Check the Label and Fiber Content
The first quality check is simple: read the label. A real mulberry silk pillowcase should clearly state 100% mulberry silk or 100% pure mulberry silk. If the label only says satin, silky, silk-feel, or luxury fabric, it may not be natural silk.
For brand buyers, labels are not enough by themselves. Ask the supplier for fabric composition, silk type, momme weight, color options, care instructions, and production tolerance. Clear documentation is a stronger sourcing signal than vague luxury language.
Understand Silk Grade and Momme Weight
Grade 6A is widely used to describe high-quality long-fiber mulberry silk. It suggests smoother, more uniform silk filaments, but grade alone does not define the whole pillowcase. Buyers should also check fabric weight, weave, finishing, dyeing, sewing, and packaging.
Momme is a fabric weight measurement commonly used for silk. A higher momme often feels more substantial and durable, while a lighter momme can feel softer and more delicate. For pillowcases, the right momme depends on the target customer, retail price, climate, and desired hand feel.
| Quality factor | What to check | Why it matters |
|---|---|---|
| Fiber content | 100% mulberry silk declaration | Confirms the product is not only synthetic satin or silk-like fabric |
| Silk grade | Grade 6A or equivalent long-fiber quality | Supports smoother hand feel and more stable fabric quality |
| Momme weight | Appropriate silk weight for pillowcase use | Affects durability, opacity, drape, and perceived value |
| Craftsmanship | Clean seams, stable closure, neat label placement | Determines whether the pillowcase feels premium after repeated use |
Evaluate Texture, Luster, and Hand Feel
Authentic mulberry silk should feel smooth and soft without rough patches. Its luster is usually gentle and natural rather than harsh or plastic-like. When you move the fabric under light, the surface should reflect softly and elegantly.
Be careful with overly shiny products. Strong shine can come from synthetic satin or finishing treatments, not necessarily high-quality silk. A premium pillowcase should balance shine, softness, drape, and breathability.
Check Stitching, Closure, and Workmanship
A high-quality pillowcase is more than silk fabric. Check the stitching line, seam strength, closure design, label position, size tolerance, and surface cleanliness. Loose threads, uneven seams, distorted corners, or poorly placed labels can lower the product value even when the fabric itself is good.
For custom orders, confirm whether the pillowcase uses envelope closure, zipper closure, flange edge, contrast piping, printed logo, woven label, care label, or retail packaging. These details affect both customer experience and production cost.
Use Safe Verification Methods
Some traditional guides mention the crunch test or burn test. A gentle crunch sound can sometimes appear when real silk is compressed, but it is not a complete proof of quality. The burn test can identify fiber behavior, but it damages the product and may be unsafe for consumers.
For brands, safer verification is better: request swatches, supplier documentation, fiber content reports when needed, pre-production samples, color approval, and bulk inspection. If the product is being developed for retail, hotel, beauty, or wellness channels, professional quality control is more reliable than home testing.
Custom Pillowcase Planning for Brands
When developing custom mulberry silk pillowcases, connect quality expectations with product positioning. A beauty brand may care most about hair and skin messaging. A hotel supplier may care more about durability and repeated washing. A gift brand may focus on color, packaging, and presentation.
- Confirm 100% mulberry silk, silk grade, and momme weight.
- Choose solid color, printed pattern, embroidery, or logo label.
- Decide envelope closure, zipper closure, flange edge, or piping.
- Check fabric hand feel, luster, color, size, seams, and labels on the sample.
- Plan care cards, pouches, boxes, ribbons, or other custom packaging.
- Review related fabric, color, and craftsmanship options before bulk production.

Frequently Asked Questions
How can I tell if a pillowcase is real mulberry silk?
Start with the label and supplier documentation. A real mulberry silk pillowcase should clearly state 100% mulberry silk or 100% pure mulberry silk. Then check the hand feel, natural luster, weave density, stitching, and whether the supplier can provide fiber content and quality details.
What does Grade 6A mulberry silk mean?
Grade 6A is commonly used to describe high-grade long-fiber mulberry silk. For pillowcases, it usually indicates a smoother, more uniform filament quality, but buyers should still check momme weight, weave, finishing, stitching, and supplier reliability.
Is a burn test recommended for checking a silk pillowcase?
A burn test can identify fiber behavior, but it is not recommended for finished consumer products because it damages the item and may be unsafe. Brands should rely on supplier documentation, lab testing, swatches, and professional quality checks instead.
What momme weight is good for mulberry silk pillowcases?
Many premium silk pillowcases use a medium-to-high momme weight because it gives better opacity, durability, and drape. The best choice depends on product positioning, target price, hand feel, season, and packaging level.
