Type “silk pillowcase wholesale” into any B2B platform and you will drown in listings. Prices range from under two dollars to over twenty for what every listing calls “100% mulberry silk.” They cannot all be telling the truth — and most of them are not. The wholesale silk market is one of the most mislabeled corners of the bedding trade, where polyester satin wears a silk name tag and buyers discover the fraud only when customers complain.
The defense is knowledge. Silk has a grading system, a weight system, and a set of physical properties that no synthetic can fully imitate. This guide walks through mulberry silk grades from 3A to 6A, explains what momme weight really tells you, and gives you five practical tests to separate genuine silk from polyester satin — before you wire a deposit. It is written for buyers sourcing at wholesale, where one wrong container erases a year’s margin.
Why the Wholesale Silk Market Is So Full of Fakes
The economics explain the fraud. Genuine mulberry silk costs several times more than polyester filament at the yarn stage, and the gap widens after weaving, будах, болон дуусгах. A supplier who substitutes polyester satin for silk pockets the entire difference — which is why “торго” pillowcases at polyester prices are never a bargain. They are a different product.
The mislabeling takes several forms. The crudest is pure polyester satin sold as silk. More sophisticated is a silk-polyester blend labeled 100% торго, or low-grade wild silk (tussah) passed off as mulberry. Some suppliers use real silk but at 16 momme — tissue-thin fabric that pills and tears within months — while charging for 22 momme quality. Each version exploits a buyer who cannot read a silk specification. By the end of this guide, you will be able to.
Mulberry Silk Grades: What 3A to 6A Actually Mean
Silk grading measures the quality of the raw silk fiber before it is woven: the length and uniformity of the filament, the number of defects, and the luster. The scale runs from A at the bottom through 2A, 3А, 4А, 5А, and 6A at the top. For pillowcases, the grades that matter commercially are 3A through 6A.
Grade 6A is the top of the scale: the longest, most uniform filaments with the fewest defects and the highest natural luster. It weaves into the smoothest, most lustrous fabric and commands the highest price. This is the grade behind genuine luxury positioning — the pillowcase a premium brand can sell at a premium price with a straight face.
Grade 5A is excellent silk with marginally more variation than 6A. In a finished pillowcase, most customers cannot distinguish 5A from 6A by hand. For wholesale buyers, 5A often represents the sweet spot: near-top quality at a meaningfully lower raw material cost.
Grade 4A is good commercial-grade silk — smooth, lustrous, and durable enough for a quality product, with slightly more visible variation in the filament. Many mid-range silk pillowcase programs are built on 4A.
Grade 3A is the entry point for legitimate mulberry silk pillowcases. The fabric is genuine silk with a decent hand, but the luster is duller and the surface shows more irregularity. Below 3A, the fiber is better suited to linings and industrial uses than to a product sold on luxury.
Two warnings. Эхлээд, grading is done on the raw silk, not the finished pillowcase — a supplier claiming “6А” should be able to tell you the grade of the yarn it buys, and the claim should be consistent with the price. Хоёрдугаарт, grade and weight are independent: a 6A silk at 16 momme is still a thin fabric. Always specify both.
Momme: The Weight System That Tells the Truth
Momme (mm) is the traditional weight unit for silk fabric: the weight in pounds of a 45-inch by 100-yard piece. For pillowcases, momme is the single most useful number on the specification, because it predicts durability more honestly than any marketing word.
- 16 momme: lightweight and delicate. Feels luxurious out of the bag but wears thin quickly; seams stress and the fabric is prone to tearing at the envelope closure. Common in ultra-cheap “торго” listings — often the reason they are cheap.
- 19 momme: the commercial standard for quality silk pillowcases. Good balance of drape, luster, болон бат бөх чанар. This is the weight serious mid-range programs specify.
- 22 momme: substantial and long-wearing, with a richer hand and deeper luster. The choice for premium positioning and for products that must survive years of nightly use and weekly washing.
- 25 momme and above: heavyweight silk, increasingly rare and expensive. Genuine luxury territory; verify the claim carefully, because this is where substitution fraud concentrates.
When a supplier quotes you, the specification should read like an engineering drawing, not a poem: “100% ялам торго, grade 5A, 22 momme, charmeuse weave.” If the quote says only “high quality silk,” you have been given a price for a mystery. гэх мэт үйлдвэрлэгч Nantong Integrity Textile — which produces bedding across cotton, зотон, хулсан эслэг, Tencel, and flannel from its own workshops — will always push vague specifications back to you with precise questions, because precise specifications are the only thing a factory can cost honestly.
Charmeuse Weave: Why Real Silk Pillowcases Shine on One Side
Almost all silk pillowcases use a charmeuse weave — a satin-type weave with long floats on the face that create the signature luster, and a dull crepe-like back. This asymmetry is a useful authenticity clue: genuine silk charmeuse has a distinctly matte reverse side. Полот “сатин” imitations are often shiny on both sides, or shiny in a flat, plasticky way that does not change with the viewing angle.
Real silk’s luster is also directional and soft — it glows rather than glares, shifting subtly as the fabric moves. Polyester’s shine is harsher and more uniform, like a photograph of silk rather than silk itself. Train your eye on a known-genuine swatch once, and the difference becomes obvious forever. Ask any prospective supplier to send a cut swatch before you discuss quantities; a supplier confident in its silk will mail one without hesitation.
Five Tests That Expose Fake Silk
You do not need a laboratory to catch most fraud. These five tests, in order of reliability, will filter out the vast majority of fakes.
Test 1: The Burn Test
Pull a few threads from a seam allowance and burn them. Real silk — a protein fiber — burns slowly, smells distinctly of burnt hair, and leaves a crushable black ash. Polyester melts, smells sweet or chemical, and leaves a hard black bead that cannot be crushed. This is the single most decisive home test. Do it on every new supplier’s sample, and do it again on the bulk shipment.
Test 2: The Price Logic Test
Know the floor. Genuine 19-momme mulberry silk pillowcases cannot wholesale for the price of polyester, because the raw material alone costs more than the fake’s finished price. If a quote is dramatically below every other genuine-silk quote, it is not a bargain — it is a different fiber. Collect three to five quotes, discard the outlier at the bottom, and investigate the outlier at the top.
Test 3: The Hand and Warmth Test
Silk feels warm to the touch almost immediately — it conducts your body heat back to you. Polyester feels cool and clammy, then plasticky as it warms. Silk also has a dry, slightly textured “scroop” when bunched; polyester feels slippery in a uniform, almost oily way. Scrunch a corner in your fist: real silk springs back with soft wrinkles, while polyester either stays creased or snaps back too perfectly.
Test 4: The Sheen Test
Hold the fabric under a single light source and tilt it. Genuine charmeuse shows a soft, shifting luster that moves across the surface. Polyester satin shows a flat, bright shine that looks the same from every angle. Check the reverse side too — real silk charmeuse is matte on the back.
Test 5: The Label and Documentation Test
Fiber content labeling is regulated in most major markets, ба “100% торго” on a label is a legal claim. Ask the supplier for fiber content test reports from an accredited lab, and check whether the company holds OEKO-TEX Standard 100 certification covering silk products. A factory certified to ISO 9001, Исаа 14001, Исаа 45001, болон OEKO-TEX стандарт 100 - гэх мэт БҮТЭН БАЙДЛЫН НЭХМЭЛ is — operates the kind of documented quality system where substitution fraud is structurally difficult, because every lot is traceable through inspection records.
What to Specify in a Silk Pillowcase RFQ
Wholesale silk buying goes wrong most often at the specification stage, not the negotiation stage. Send every supplier the identical specification so quotes are comparable, and include these lines:
- Fiber and grade: 100% ялам торго, grade 5A (or 6A for premium)
- Жин: 22 momme (эсвэл 19 momme for mid-range) — never omit this
- Нэхэх: charmeuse, lustrous face out
- Хэмжээ: finished dimensions in cm or inches, жишээ нь, 50 x 75 см, plus envelope or zipper closure
- Өнгө: Pantone TCX reference or physical standard; state tolerance
- Quantities and tiers: жишээ нь, 500 / 1,000 / 3,000 pieces per color
- Сав баглаа боодол: individual polybag, gift box, insert card, private label
- Зорилтот үнэ: one all-in price per tier — a factory running a “Зорилтот үнийг хүндэтгэх” policy will answer make or no-make instead of haggling
- Testing: fiber content verification and OEKO-TEX compliance required
Notice what this specification does: it removes every hiding place. A supplier who cannot meet “grade 5A, 22 momme” must either decline honestly or quote a different specification openly — both acceptable outcomes. What you must never accept is a quote against this specification at a price that only polyester can deliver.
Wholesale Buying Tips: Protecting Margin on a Fraud-Prone Product
Silk pillowcases carry some of the best margins in bedding accessories, which is exactly why they attract the most fraud. Protect the margin with process. Эхлээд, always start with paid samples from two or three suppliers and run the burn test on each — the small sample cost is the cheapest insurance you will ever buy. Хоёрдугаарт, write the specification into the contract with a remedy clause: if lab testing finds the bulk goods are not 100% mulberry silk at the specified momme, the supplier replaces or refunds. Гуравдугаарт, inspect the bulk shipment against the approved sample, checking sheen, жин, and construction — not just color. Дөрөвдүгээрт, build the relationship before you scale: a factory that has made your 500-piece trial honestly is the factory you trust with 5,000 жижиг хэрэгсэл.
On pricing, understand what moves the number. Grade steps (5A to 6A), momme steps (19 руу 22), and order quantity are the three real levers; everything else is noise. A supplier offering “6A 25-momme” at a 19-momme price is not generous — the specification is fiction. And when you have collected genuine quotes, use the target-price approach: show the range you have seen, name one price, and ask for a make-or-no-make answer. Serious factories prefer this. It replaces weeks of theater with one honest decision.
Байнга асуудаг асуултууд
What is the best momme for wholesale silk pillowcases?
19 momme is the commercial standard for quality programs — a good balance of luxury hand, бат бөх чанар, болон зардал. 22 momme suits premium positioning and heavier use. Avoid 16 momme for wholesale; it is too fragile for a product sold on durability, and its low price is the reason it appears in so many misleading listings.
Is 6A silk worth the premium over 5A?
For most wholesale programs, no. The visible and tactile difference between 5A and 6A in a finished pillowcase is minimal, while the raw material premium is real. Specify 6A only when your brand story and retail price genuinely require top-grade positioning. Spend the savings on momme instead — customers feel weight every night, but almost no one can feel a grade step.
Can I trust a supplier’s “100% ялам торго” label?
Итгэл, then verify. The label is a legal claim in most markets, but enforcement happens after the damage. Verify with the burn test on samples, require fiber content test reports for bulk orders, and prefer suppliers with OEKO-TEX Standard 100 certification covering their silk products. A documented quality system is the best predictor of an honest label.
How do silk pillowcases differ from satin pillowcases?
“Satin” describes a weave, not a fiber. A silk pillowcase is almost always a silk charmeuse (a satin-type weave in silk fiber). А “satin pillowcase” with no fiber stated is almost always polyester satin — shiny, slippery, and lacking silk’s temperature regulation, Чадуу хөгжил, and protein-fiber softness. When a listing says “торго” but the price says “полиэфир,” believe the price.
What minimum order should I expect for custom silk pillowcases?
It varies by factory and by whether the color is stock or custom-dyed. Stock colors in standard sizes can start in the low hundreds of pieces; custom colors or custom sizes typically need higher commitments because dyeing has setup costs. Ask for tiered pricing — for example 500, 1,000, ба 3,000 pieces — so you can see exactly where the price breaks before you commit.
How should silk pillowcases be packaged for retail?
At minimum, an individual protective polybag with a sewn-in private label and care instructions. For gift and premium positioning, a rigid gift box with an insert card dramatically lifts perceived value — packaging is often the difference between a commodity listing and a giftable product. Confirm packaging specifications and costs in the RFQ; they are frequently five to ten percent of landed cost.
Source Silk You Can Prove
The wholesale silk market rewards buyers who specify precisely and verify ruthlessly. Grade, momme, нэхэх, and closure in the RFQ; burn test and lab reports in verification; a documented quality system behind the supplier. Do that, ба “100% ялам торго” becomes a fact you can print on the label with confidence instead of a hope you paid for.
