Why B2B Buyers Must Master Silk Authentication

When sourcing mulberry silk fabric for your private label products, the financial stakes are substantial. A single container of 22mm silk fabric represents a significant investment, and receiving inferior polyester disguised as silk can devastate your business.

Beyond financial losses, counterfeit silk damages brand credibility. Your customers expect the luxurious feel and skin benefits of genuine silk—polyester alternatives cannot deliver these experiences. Understanding how to test real silk has become a non-negotiable skill for every silk procurement professional.

The Science Behind Authentic Mulberry Silk

Genuine mulberry silk originates from the cocoons of Bombyx mori silkworms that feed exclusively on mulberry leaves. This specialized diet produces silk fibers with unique molecular structures that define authentic silk’s exceptional properties:

  • Triangular prism structure: Refracts light at different angles, creating silk’s characteristic iridescent sheen
  • Protein-based composition: Contains 18 amino acids beneficial for skin and hair
  • Natural temperature regulation: Keeps users cool in summer and warm in winter
  • Moisture-wicking properties: Absorbs moisture without feeling damp

These properties are impossible to replicate with synthetic fibers, which is why professional silk product testing methods can reliably detect authenticity.

Professional Testing Methods for Authenticating Silk

1. The Burn Test: The Gold Standard

Perhaps the most reliable field test for silk pillowcase manufacturers and buyers alike is the burn test. Here is how professionals conduct this examination:

Take a small fiber sample and hold it with tweezers near a flame. Observe the following characteristics:

Characteristic Authentic Mulberry Silk Synthetic Imitation
Ignition behavior Slow to ignite, self-extinguishing Melts first, then burns rapidly
Flame color Small yellow flame Bright orange flame with melting
Odor Resembles burning hair or feathers Smells like burning plastic or chemicals
Ash residue Crushable black ash Hard bead-like residue
Smoke Minimal, gray smoke Black, acrid smoke

Our quality control team performs this test on every batch. When manufacturing silk accessories, we ensure each production run meets strict authenticity standards.

2. Microscopic Fiber Analysis

Under magnification, genuine silk fibers display distinctive characteristics invisible to the naked eye. Professional laboratories and experienced silk product manufacturers use this method for definitive authentication:

  • Fiber uniformity: Natural silk shows consistent diameter throughout
  • Smooth surface: Fibers appear glossy and uniformly structured
  • No splitting: Individual fibers remain intact under magnification
  • Natural irregularities: Subtle variations confirm organic origin

Synthetic polyester, even high-quality “silk-like” fabrics, shows obvious manufacturing imperfections under the microscope—visible seams, uniform plastic appearance, and mechanical uniformity that betrays its artificial nature.

3. The Water Absorption Test

Genuine mulberry silk demonstrates remarkable hydrophilicity due to its protein structure. When a water droplet contacts authentic silk, it spreads rapidly and absorbs within seconds. Polyester and other synthetics repel water, causing droplets to bead and roll off the surface.

This test is particularly valuable when inspecting finished products like wholesale silk pillowcases without damaging them.

4. Chemical Testing for Definitive Results

For absolute certainty in silk authenticity verification, chemical tests provide conclusive evidence:

  • Sulfuric acid test: Silk dissolves in concentrated sulfuric acid while synthetics do not
  • Acetone test: Genuine silk remains unaffected; some synthetics dissolve or discolor
  • Zinc chloride test: Authentic silk fibers swell and dissolve in this solution

These tests require laboratory conditions but offer the highest level of certainty for B2B silk procurement professionals making significant purchasing decisions.

Physical Characteristics: What to Look For

Beyond laboratory testing, experienced silk buyers develop an eye for authentic silk through careful observation of physical properties:

Luster and Sheen

Authentic mulberry silk displays what experts call a “soft, diffused luster”—a gentle, multi-dimensional shine that shifts with viewing angle. Counterfeit silk typically shows a flat, plastic-like sheen or an unnaturally bright shine that looks artificial under lighting.

Touch and Feel

The tactile experience of genuine silk is unmistakable:

  • Temperature: Authentic silk feels cool to the touch and quickly warms with skin contact
  • Texture: Smooth without slipperiness, with a subtle grip that feels luxurious
  • Weight: Real silk has a characteristic weight that feels substantial yet light
  • Drape: Flows naturally without stiffness or excessive fluidity

Comparing authentic silk against known samples, as demonstrated in our silk versus bamboo comparison, helps train procurement teams to recognize quality.

The Wrinkle Test

Genuine silk wrinkles differently than synthetic alternatives. When crumpled, authentic silk forms soft, flowing wrinkles with gentle creases. Polyester tends to form sharp, plastic-like creases that persist and may even appear permanent.

Understanding Momme Weight and Quality Grades

Authentic silk quality is measured in momme (mm), with higher numbers indicating denser, more luxurious fabric. Professional B2B silk buyers understand this grading system:

Momme Weight Quality Grade Best Applications Characteristics
8-12 mm Lightweight Lining, scarves Sheer, delicate appearance
14-16 mm Standard Pillowcases, light garments Balance of quality and affordability
19-22 mm Premium Luxury bedding, sleepwear Rich luster, substantial feel
25-30 mm Ultra-Premium Luxury accessories, high-end bedding Maximum durability and opulence

When sourcing private label silk accessories, specifying momme weight protects you from receiving inferior products disguised under vague descriptions.

Certifications and Documentation

Reputable silk suppliers provide comprehensive documentation to verify authenticity:

  • Oeko-Tex Standard 100: Certifies absence of harmful substances
  • GOTS certification: Confirms organic silk production methods
  • Laboratory test reports: Provides scientific verification of fiber composition
  • Raw material certificates: Documents the source of silk cocoons

Our commitment to transparency means we provide full documentation for every order, as detailed in our quality assurance processes.

Protecting Your Silk Supply Chain

Establishing reliable silk sourcing relationships requires multiple verification layers:

Supplier Verification Checklist

  • Request physical samples before placing bulk orders
  • Conduct or request third-party laboratory testing
  • Verify supplier manufacturing capabilities and certifications
  • Request references from other B2B clients
  • Start with smaller trial orders to establish trust

The investment in thorough verification protects against far greater losses from counterfeit products. Our team at GzDreamway welcomes contact for custom silk manufacturing inquiries, where we demonstrate our commitment to authentic, premium-quality silk products.

Frequently Asked Questions

What is the minimum order quantity for authentic mulberry silk products?

At our manufacturing facility, the minimum order quantity (MOQ) is 50 pieces per design for silk products. This MOQ applies to standard pillowcases, eye masks, and other silk accessories. For custom private label orders, we offer flexible production options that accommodate various order volumes while maintaining our rigorous quality standards. Bulk orders typically qualify for additional pricing benefits and priority production scheduling.

How can I verify silk authenticity without damaging the product?

Non-destructive testing methods include examining luster quality under different lighting conditions, performing the water absorption test on hidden areas, checking fabric weight against stated momme specifications, and observing how the fabric drapes and wrinkles. For valuable finished products, we recommend working with third-party textile testing laboratories that specialize in fiber authentication using microscopic and chemical analysis methods.

What certifications should I look for when sourcing silk?

Essential certifications include Oeko-Tex Standard 100 (safety), GOTS (organic), and ISO quality management certifications. Request documentation of fiber composition testing, which should confirm 100% mulberry silk content. Reputable manufacturers provide certificates of authenticity and laboratory test reports from recognized testing facilities.

Why does authentic mulberry silk cost more than alternatives?

Genuine mulberry silk requires specialized production: silkworms fed exclusively on mulberry leaves, careful cocoon harvesting, delicate fiber reeling processes, and skilled weaving. This labor-intensive, time-sensitive production explains the premium pricing compared to synthetic alternatives that can be manufactured rapidly with automated processes.

Can I request samples before placing bulk silk orders?

Absolutely. We strongly encourage all B2B clients to request samples before committing to large orders. Sample orders allow you to conduct your own authenticity testing, evaluate physical properties, and ensure the silk meets your quality expectations.

佐藤 優子2026-08-06
2026-08-06 のブログ記事を読みました。B2Bバイヤーとして、100%マルベリーシルクの裏地は、特に日本市場向けのハンドバッグOEM製造において、非常に重要です。しかし、サンプルの風合いが硬く、光沢が鈍かったのは気になりました。私たちは東京で高級ブランドを展開しており、色の一貫性とサプライチェーンの透明性に厳しい基準を設けています。「momme weight testing」と「FTIR silk analysis」をぜひ活用したいです。現在、サプライヤー選定中で、少量パイロットランで品質を確認したいです。工場の「sericin residue check」についても知りたいです。宜しくお願いします。
GZDreamway2026-08-06
佐藤様、お問い合わせありがとうございます。サンプルの硬さと光沢の鈍さは、典型的なセリシン残留または加工工程の問題です。当工場では、入荷時検品として「momme weight testing」と顕微鏡による繊維識別を即座に行い、100%マルベリーシルクの純度を確認します。その後、皆様のご要望に応じて「FTIR silk analysis」で合成繊維の混入がないかを徹底的に検査します。特に日本市場向けには、「sericin residue check」を実施し、必要に応じて追加の「degumming」工程を提案し、本来の柔らかさと自然な光沢を再現します。色の一貫性については、お客様のカラースワッチをもとに「lab-dye」で試作し、分光光度計でΔEを測定した後、「small pilot runs」(推奨100〜300メートル)で実生産条件下での色検証を行います。全バッチに「batch-level SGS reports」と「OEKO-TEX」証明書を添付し、「traceability of silk supply chain」を保証します。パイロットで問題が発生した場合は、「Non-Conformance Report」を発行し、再テストや再染色のオプションを提示します。サンプルと色見本をお送りいただければ、項目別の費用明細と共に、日本市場向けの詳細なテストプランをご提案します。

Dear Sato-san, thank you for your inquiry. The hardness and dull luster of the samples are typical issues related to sericin residues or processing methods. In our factory, we immediately conduct incoming quality control with momme weight testing and microscopic fiber ID to confirm 100% mulberry silk purity. Then, if required, we perform FTIR silk analysis to thoroughly check for synthetic fiber contamination. For the Japanese market, we conduct sericin residue checks and offer additional degumming to restore natural softness and sheen. Regarding color consistency, we begin with your color swatches, perform lab-dyeing with spectrophotometric ΔE measurement, and then run small pilot batches (recommended 100–300 meters) to validate color and hand feel under real production conditions. All batches are accompanied by batch-level SGS reports and OEKO-TEX certificates, ensuring full traceability of the silk supply chain. If any issue arises during the pilot, we issue a Non-Conformance Report and propose retest or recolor options. Please send your representative samples and color swatches so we can prepare a detailed test plan with itemized costs for the Japanese market. |

We received the mulberry silk lining swatches for our new line of vegan leather handbags, and while the feel is promising, the color on the edge seems a bit washed out compared to the center. We're a Seattle-based startup focusing on sustainable custom handbag manufacturing, and our customers are very particular about organic silk certification and zero-waste production. Do you use any specific dyeing technique for edge-to-edge color consistency in short runs? We're exploring small batch customization and need a supplier who can handle unique Pantone matching without a huge minimum order. Also, could you share what your typical lead time is for a 200-meter pilot run to cross-check the shade? Our last supplier had a 10-day turnaround, but we're hoping for a faster iteration loop on these eco-friendly deodorant bag liners. If you have any case studies or B2B testimonials from other sustainable bag brands in North America, that would help us validate the partnership before we commit to a larger procurement cycle. We're also curious about your return policy for defective rolls fabric in transit. |
GZDreamway2026-08-04
Hi Hannah, thanks for the detailed note—edge-to-edge color consistency is a classic pain point in custom handbag manufacturing, and we've tackled it head-on in our Guangzhou facility. We start by calibrating our dye formulas with a spectrophotometer to measure ΔE across the full width of the fabric, not just the center, which catches any uneven absorption early. For your sustainable line, we can offer a 200-meter pilot run with a 7-day lead time, including lab-dip approval, so you can validate the shade quickly. We also use an additional degumming step to ensure the silk takes dye evenly, reducing edge fade. For B2B buyers like you, we've developed a lean process for organic silk certification and zero-waste production, and we can share case studies from similar North American eco-brands upon request. If any fabric defects arrive in transit, our return policy covers replacement within 15 days, provided you send photos and a small sample for our internal review. Let's schedule a video call to walk through your specific Pantone needs and our small batch customization workflow—we're flexible with minimums and can adjust the timeline to meet your iteration loop. We're committed to helping you launch this line smoothly.

Chloé Bernard2026-08-02
Bonjour, je suis responsable qualité chez une maroquinerie de Genève. Nous avons reçu des échantillons de doublure en soie de mûrier pour notre ligne de sacs à main personnalisés, mais le tissu était plus rigide que prévu et le brillant semblait trop prononcé, ce qui est gênant pour notre clientèle exigeante qui valorise la douceur et un rendu naturel. Le marché suisse requiert une transparence totale sur la chaîne d'approvisionnement et des certifications comme OEKO-TEX, et nous aimerions savoir comment vous effectuez le test de poids momme (momme weight testing) et l'analyse FTIR (FTIR silk analysis) pour confirmer la pureté. De plus, pour une commande OEM, nous souhaitons valider la couleur avec un petit lot pilote de 200 mètres car nous avons eu des écarts de teinte par le passé avec d'autres fournisseurs. Pourriez-vous aussi détailler votre gestion des résidus de séricine (sericin residue check) pour améliorer le toucher et assurer une consistance de couleur (color consistency) avant la production en série ? Merci d'avance pour vos éclaircissements.
GZDreamway2026-08-02
Bonjour Chloé, merci pour votre retour détaillé. Nous comprenons parfaitement vos préoccupations concernant la rigidité et le brillant excessif, qui sont souvent dus à des résidus de séricine non éliminés ou à un calandrage trop agressif. Pour le marché suisse, nous avons mis en place un protocole rigoureux. Dès réception de vos échantillons, nous effectuons un momme weight testing avec des balances calibrées pour vérifier la densité du tissu, suivi d'une identification microscopique des fibres pour confirmer qu'il s'agit bien de 100% soie de mûrier. Si un doute persiste, nous passons à une analyse FTIR qui détecte toute trace de polyester ou de nylon. Pour le toucher, nous réalisons un contrôle des résidus de séricine et proposons un dégommage supplémentaire pour restaurer la souplesse et le tombé naturel, essentiel pour vos doublures de luxe. Concernant l'approbation des couleurs, nous commençons par vos échantillons de couleur, suivis d'une teinture en laboratoire avec mesure ΔE par spectrophotomètre, puis nous produisons un petit lot pilote de 200 mètres, comme vous le souhaitez, pour valider la teinte et le toucher en conditions réelles. Nous fournissons des rapports SGS par lot et des certificats OEKO-TEX pour une traçabilité totale. Envoyez-nous vos échantillons et nuanciers, nous préparerons un plan de test détaillé avec devis par article.

Hello Chloé, thank you for your detailed feedback. We fully understand your concerns about the stiffness and excessive sheen, which are often due to sericin residues that have not been removed or overly aggressive calendering. For the Swiss market, we have a rigorous protocol in place. Upon receiving your samples, we perform momme weight testing with calibrated scales to verify fabric density, followed by microscopic fiber ID to confirm 100% mulberry silk. If any doubt remains, we proceed with FTIR analysis to detect any polyester or nylon traces. For the hand feel, we conduct a sericin residue check and offer additional degumming to restore softness and natural drape, essential for luxury linings. For color approval, we start with your color swatches, then lab-dye with spectrophotometric ΔE measurement, and produce a small pilot run of 200 meters to validate shade and hand feel under real conditions. We provide batch-level SGS reports and OEKO-TEX certificates for full traceability. Please send your samples and color swatches; we will prepare a detailed test plan with itemized quotes.

Bonjour, je suis responsable des achats pour une marque de maroquinerie à Bruxelles. Nous avons reçu des échantillons de doublure en soie de mûrier pour notre ligne de sacs à main haut de gamme, mais le tissu était plus rigide que prévu et le brillant semblait trop prononcé. Pour le marché belge, qui exige une qualité irréprochable et des certifications comme OEKO-TEX, c'est un vrai problème. Pourriez-vous me détailler votre processus de test momme weight et d'analyse FTIR pour confirmer la pureté de la soie, ainsi que votre gestion des résidus de séricine pour améliorer la souplesse ? Aussi, comment gérez-vous l'approbation des couleurs avec de petits lots pilotes pour garantir une teinte parfaite avant la production en série ? Merci pour votre retour.

Bonjour Jean-Pierre, merci pour votre retour. Nous comprenons parfaitement vos préoccupations concernant la rigidité et le brillant excessif, qui sont souvent dus à des résidus de séricine non éliminés ou à un calandrage trop agressif. Pour le marché belge, nous avons mis en place un protocole rigoureux. Dès réception de vos échantillons, nous effectuons un momme weight testing avec des balances calibrées pour vérifier la densité du tissu, suivi d'une identification microscopique des fibres pour confirmer qu'il s'agit bien de 100% soie de mûrier. Si un doute persiste, nous passons à une analyse FTIR qui détecte toute trace de polyester ou de nylon. Pour le toucher, nous réalisons un contrôle des résidus de séricine et proposons un dégommage supplémentaire pour restaurer la souplesse et le tombé naturel, essentiel pour vos doublures de luxe. Concernant l'approbation des couleurs, nous commençons par vos échantillons de couleur, suivis d'une teinture en laboratoire avec mesure ΔE par spectrophotomètre, puis nous produisons un petit lot pilote de 200 à 300 mètres pour valider la teinte et le toucher en conditions réelles. Nous fournissons des rapports SGS par lot et des certificats OEKO-TEX pour une traçabilité totale. Envoyez-nous vos échantillons et nuanciers, nous préparerons un plan de test détaillé avec devis par article.

Bonjour, je suis responsable qualité pour une maison de maroquinerie à Montréal. Nous avons reçu un échantillon de doublure en soie de mûrier pour notre ligne de sacs à main personnalisés, et bien que l'étiquette annonce 100% soie, le toucher est plutôt rigide et le lustre semble trop prononcé, ce qui est gênant pour notre clientèle exigeante au Canada. Le marché nord-américain requiert une transparence totale sur la chaîne d'approvisionnement et des certificats comme OEKO-TEX pour nos commandes OEM. J'aimerais savoir comment vous effectuez le test de poids momme (momme weight testing) et l'analyse FTIR pour confirmer la pureté du tissu. De plus, en tant que nouveaux acheteurs, nous souhaitons valider la couleur avec un petit lot pilote de 250 mètres avant de lancer une production complète, car nous avons déjà eu des écarts de teinte avec d'autres fournisseurs. Pourriez-vous me détailler votre processus de contrôle qualité, notamment la gestion des résidus de séricine pour améliorer la souplesse du tissu ? Merci d'avance pour votre retour. |

Bonjour Camille, merci pour votre message détaillé. Nous comprenons tout à fait votre préoccupation concernant la rigidité et le brillant excessif, qui sont souvent attribuables à des résidus de séricine non éliminés ou à un calandrage trop agressif. Pour répondre à vos besoins spécifiques pour le marché montréalais, notre protocole commence par un contrôle entrant où nous effectuons un momme weight testing à l'aide de balances calibrées pour vérifier la densité du tissu, suivi d'une identification microscopique des fibres pour confirmer qu'il s'agit bien de 100% soie de mûrier. Si un doute persiste sur la pureté, nous avons développé un système d'analyse FTIR qui détecte toute trace de polyester ou de nylon, garantissant ainsi une authenticité irréprochable. Pour ce qui est de la texture, nous réalisons un contrôle des résidus de séricine par un test de dégommage contrôlé ; si le taux est élevé, nous proposons un dégommage supplémentaire pour adoucir le tissu et lui donner un tombé plus naturel, essentiel pour les doublures de luxe. Concernant l'approbation des couleurs pour votre commande OEM, notre processus inclut l'envoi de vos échantillons de couleur, une teinture en laboratoire avec mesure ΔE par spectrophotomètre pour garantir une consistance chromatique parfaite, puis la production d'un petit lot pilote de 250 mètres, comme vous le souhaitez, pour valider la teinte et le toucher dans des conditions réelles. Nous fournissons un rapport SGS par lot et un certificat OEKO-TEX pour assurer une traçabilité totale de la chaîne d'approvisionnement. Si ce pilote ne répond pas à vos attentes, nous émettons un rapport de non-conformité et proposons des ajustements, comme une retinte ou un traitement supplémentaire. N'hésitez pas à nous envoyer vos échantillons représentatifs et vos nuanciers ; nous préparerons un plan de test détaillé avec des devis par article pour chaque analyse effectuée. Nous serions ravis de collaborer avec votre maison et de vous offrir une qualité irréprochable pour vos sacs à main personnalisés.

Hello Camille, thank you for your detailed message. We fully understand your concern about the stiffness and excessive sheen, which are often due to sericin residues that have not been removed or an overly aggressive calendering process. To meet your specific needs for the Montreal market, our protocol begins with an incoming inspection where we perform momme weight testing using calibrated scales to verify fabric density, followed by microscopic fiber identification to confirm it is indeed 100% mulberry silk. If any doubt remains about purity, we have developed an FTIR analysis system that detects any trace of polyester or nylon, thus ensuring irreproachable authenticity. For texture, we perform a sericin residue check through a controlled degumming test; if the level is high, we offer additional degumming to soften the fabric and give it a more natural drape, essential for luxury linings. Regarding color approval for your OEM order, our process includes sending your color swatches, laboratory dyeing with spectrophotometric ΔE measurement to guarantee perfect color consistency, and then producing a small pilot run of 250 meters, as you requested, to validate the shade and hand feel under real conditions. We provide a batch-level SGS report and an OEKO-TEX certificate to ensure full traceability of the silk supply chain. If this pilot does not meet your expectations, we issue a non-conformance report and suggest adjustments, such as recoloring or additional treatment. Feel free to send us your representative samples and color swatches; we will prepare a detailed test plan with itemized quotes for each analysis performed. We would be delighted to collaborate with your house and offer you impeccable quality for your custom handbags. |

Bonjour, je suis responsable des achats pour une petite marque de maroquinerie basée à Bordeaux. Nous avons reçu des échantillons de doublure en soie de mûrier étiquetés 100 % pure, mais le toucher est légèrement rugueux et le brillant semble un peu artificiel par endroits, ce qui est gênant pour notre collection automne-hiver. Le marché français, surtout en province, exige une traçabilité irréprochable avec des certificats OEKO-TEX pour les commandes OEM destinées aux boutiques haut de gamme. Pourriez-vous me détailler votre processus de test de pureté, notamment le momme weight testing et l'analyse FTIR, ainsi que la gestion des résidus de séricine pour améliorer la douceur ? J'aimerais aussi savoir si vous proposez des petits lots pilotes de 200 à 300 mètres pour valider la teinte avant la série, car nous avons eu des surprises de variation de couleur sur des commandes précédentes.
GZDreamway2026-07-30
Bonjour Léa, merci pour votre retour. La rugosité et le brillant irrégulier que vous décrivez sont souvent causés par un excès de résidus de séricine ou une contamination légère par des fibres synthétiques, un défi récurrent dans l'approvisionnement en soie pour le marché français du luxe. Dans notre usine à Guangzhou, nous avons développé un protocole de contrôle qualité en plusieurs étapes pour garantir la pureté et la consistance. Sur réception de vos échantillons, nous effectuons un test de poids momme avec des balances de laboratoire calibrées pour mesurer la densité du tissu. Ensuite, nous réalisons une identification microscopique des fibres pour confirmer la présence de 100 % soie de mûrier. Si le toucher ou l'aspect reste douteux, nous passons à une analyse FTIR qui utilise la spectroscopie infrarouge pour détecter même des traces de polyester ou de nylon, garantissant ainsi une pureté totale. Pour la rugosité, nous effectuons un contrôle des résidus de séricine par un test de dégommage contrôlé, et nous proposons un dégommage supplémentaire pour restaurer la douceur et le lustre naturels. Concernant l'approbation des couleurs OEM, notre processus débute par l'envoi de vos échantillons de couleur, suivis d'une teinture en laboratoire avec mesure ΔE par spectrophotomètre pour assurer une parfaite consistance chromatique. Nous produisons ensuite un petit lot pilote de 200 à 300 mètres, comme vous le souhaitez, pour valider la teinte et le toucher dans des conditions de production réelles. Nous fournissons des rapports SGS par lot et des certificats OEKO-TEX pour une traçabilité complète de la chaîne d'approvisionnement. Si ce lot pilote ne correspond pas à vos attentes, nous émettons un rapport de non-conformité et proposons des options de retinte ou de test supplémentaire. Veuillez nous envoyer vos échantillons représentatifs et vos nuanciers ; nous préparerons un plan de test détaillé avec des devis par article pour chaque analyse. Nous sommes impatients de collaborer avec votre marque bordelaise.

Hello Léa, thank you for your feedback. The roughness and uneven sheen you describe are often caused by excess sericin residues or slight synthetic fiber contamination, a common challenge in silk sourcing for the French luxury market. In our Guangzhou factory, we have a multi-step quality control protocol to ensure purity and consistency. Upon receiving your samples, we perform momme weight testing using calibrated lab scales to measure fabric density. We then conduct microscopic fiber identification to confirm the presence of 100% mulberry silk. If the hand feel or appearance remains questionable, we proceed with FTIR analysis, using infrared spectroscopy to detect even trace amounts of polyester or nylon, thus ensuring total purity. For the rough texture, we perform a sericin residue check through a controlled degumming test, and we offer additional degumming to restore natural softness and luster. Regarding OEM color approval, our process starts with your color swatches, followed by lab-dyeing with spectrophotometric ΔE measurement to ensure perfect color consistency. We then produce a small pilot run of 200 to 300 meters, as you prefer, to validate both color and hand feel under real production conditions. We provide batch-level SGS reports and OEKO-TEX certificates for complete traceability of the silk supply chain. If this pilot lot does not meet your expectations, we issue a non-conformance report and propose recolor or retest options. Please send your representative samples and color swatches; we will prepare a detailed test plan with itemized quotes for each analysis. We look forward to collaborating with your Bordeaux-based brand.

エレナ・ヴァインベルク2026-07-28
先日貴社から受け取った100%マルベリーシルクのハンドバッグ裏地サンプルの触感が予想以上に硬く、光沢がややプラスチックっぽく感じました。ドイツ市場向けの高級ラインでは、自然なドレープ性と柔らかさが不可欠で、OEKO-TEX認証とカラーコンシステンシーは絶対条件です。正直なところ、このサンプルだけでは大ロット発注に踏み切れません。御社のOEM承認プロセスにおけるスモールパイロットラン(例:300メートル)の具体的な流れと、その中でどのようにモメ重量テストやセリシン残留チェックを実施しているのか教えてください。また、SGSのバッチレポートは各パイロットロットごとにも発行可能でしょうか?
GZDreamway2026-07-28
エレナ様、貴重なご意見をありがとうございます。手触りの硬さと光沢の不自然さは、まさにセリシン残留やシルクの加工工程に起因する典型的な課題であり、ドイツの高級市場で要求される基準を満たしていないのはごもっともです。当工場では、この問題を根本的に解決するために、まず入荷時にモメ重量テスト(momme weight testing)と顕微鏡による繊維同定(microscopic fiber ID)を実施し、100%マルベリーシルクであることを確認します。その後、FTIRシルク分析(FTIR silk analysis)で合成繊維の混入がないかを厳密にチェックし、さらにセリシン残留チェック(sericin residue check)で硬さの原因を特定します。必要に応じて追加の糊抜き工程(additional degumming)を提案し、ドレープ性と自然な光沢を復元します。OEMカラー承認プロセス(OEM color approval process)では、まずお客様からカラースワッチをお送りいただき、ラボダイ(lab-dye)で色合わせを行います。その後、推奨300メートルのスモールパイロットラン(small pilot run)を実施し、分光光度計を用いたΔE測定でカラーコンシステンシー(color consistency)を検証すると同時に、パイロットロットごとにSGSバッチレポート(batch-level SGS reports)とOEKO-TEX証明書を発行し、サプライチェーンの完全なトレーサビリティ(traceability of silk supply chain)を保証します。パイロット段階で問題が発生した場合は、ノンコンフォーマンスレポート(non-conformance report)を発行し、リカラーやリテストのオプションを提示します。このプロセスにより、大量生産前のすべてのリスクを排除できます。サンプルとご希望の色見本をお送りいただければ、すぐに詳細なテストプランと項目別の費用見積もりをご提案します。

Dear Elena, thank you for your valuable feedback. The stiffness and unnatural sheen you noticed are classic issues associated with sericin residues or suboptimal processing, and we fully understand why this does not meet the standards required for the German luxury market. Our factory addresses this through a systematic quality control process. Upon receipt, we perform momme weight testing and microscopic fiber ID to confirm 100% mulberry silk. If there are any concerns about hand feel, we proceed with FTIR silk analysis to rule out synthetic contamination and a sericin residue check to identify the cause of stiffness. We can then offer additional degumming to restore the desired softness and natural drape. For your OEM color approval process, we propose starting with your color swatches, followed by lab-dyeing with spectrophotometric ΔE measurement to ensure color consistency. We then recommend a small pilot run of 300 meters to validate both color and hand feel. For each pilot lot, we issue batch-level SGS reports and OEKO-TEX certificates, ensuring full traceability of the silk supply chain. If any non-conformance is found, we provide a detailed report and offer recolor or retest options before mass production. Please send your representative samples and color swatches so we can prepare a comprehensive test plan with itemized costs.
Carlos Mendoza2026-07-27
Hola, soy gerente de compras de una marca de bolsos en la Ciudad de México. Recibí muestras de forro de seda de morera etiquetadas como 100% pura, pero la textura era áspera y el brillo era mate, lo cual es decepcionante porque nuestro mercado de lujo en México exige una consistencia de color impecable y certificaciones como OEKO-TEX. ¿Podrían explicar cómo realizan pruebas de peso momme y análisis FTIR para verificar la pureza? También necesito un proceso de aprobación de color con lotes piloto pequeños para asegurar que el tono coincida antes de la producción en masa, ya que tuvimos problemas con entregas anteriores donde el color varió significativamente entre lotes.
GZDreamway2026-07-27
Hola Carlos, gracias por compartir su experiencia. Entendemos perfectamente su frustración con una textura áspera y un brillo opaco, ya que esto es un problema común en muestras iniciales que pueden tener residuos de sericina o mezclas de fibras. En nuestra fábrica en Guangzhou, hemos desarrollado un protocolo de control de calidad que aborda exactamente estos puntos para el mercado mexicano. Comenzamos con un momme weight testing en máquinas calibradas para verificar la densidad del tejido, y una identificación microscópica de fibras para confirmar que sea seda de morera al 100%. Si se sospecha una mezcla, procedemos con un análisis FTIR que puede detectar incluso trazas de poliéster o nailon. Para mejorar el tacto y el brillo, realizamos una revisión de residuos de sericina (sericin residue check) y ofrecemos un desgomado adicional para restaurar la suavidad y el lustre natural. En cuanto a la aprobación de color OEM, nuestro proceso comienza con el envío de muestras de color (color swatches) y luego realizamos un teñido de laboratorio (lab-dye) con medición ΔE por espectrofotómetro para garantizar la consistencia cromática. Luego producimos un pequeño lote piloto de 100 a 500 metros para validar el color y el tacto en condiciones de producción reales. Proporcionamos informes SGS por lote y certificados OEKO-TEX para una trazabilidad completa de la cadena de suministro (traceability of silk supply chain). Si el lote piloto no cumple con sus expectativas, emitimos un informe de no conformidad y proponemos opciones de retinte o repetición de prueba. Envíenos sus muestras representativas y muestras de color para que podamos preparar un plan de prueba detallado con costos desglosados. Estamos listos para garantizar que su próxima entrega cumpla con los estándares de lujo de México.
