Mulberry Silk: Which Claims Hold Up
Quick answer
Silk is genuinely remarkable, which is why so many claims get attached to it — and a good number of those claims do not survive being asked a simple question. Below is a claim-by-claim audit of the ones buyers are most often shown, with what is defensible and what is being overstated.
The point is not to talk silk down. It is that a specification built on claims a supplier cannot support is a specification that will not hold up when your own customer asks about it.
How to read a silk claim
Three questions settle most of them.
- Is the claim about the fibre, or about the finished cloth? "Silk is strong" is about the fibre. Whether your scarf is strong depends on the weave and the momme, which are decisions made later.
- Is it measurable, or is it an adjective? "Temperature regulating" has a mechanism behind it. "Luxurious" does not, and it cannot be checked.
- Who is making it, and what would falsify it? A claim nobody can test is a claim nobody can be held to.
The claims, audited
| Claim | What holds up | What is overstated |
|---|---|---|
| "Grade 5A / 6A raw silk" | Raw silk is graded, and the grade describes the filament. | A grade describes the raw fibre, not the finished scarf. Without a traceable statement from the reeling house, the letters on a page tell you very little. |
| "Hypoallergenic" | Silk is a protein fibre close in composition to human hair and is generally well tolerated by sensitive skin. | It is not a medical claim. Anyone can react to a dye or a finish, on any fibre. |
| "Temperature regulating" | The fibre absorbs and releases moisture and has a natural crimp, so it insulates without trapping heat the way a coated synthetic does. | It is not air conditioning. It is a real but modest effect, and it is why silk works across more of the year than wool of the same weight. |
| "Stronger than steel" | Silk has high tensile strength for its weight. | This is almost always quoted per unit of weight against a steel wire of the same diameter, which is not a comparison any buyer makes. It also says nothing about abrasion resistance. |
| "Anti-ageing" / "anti-wrinkle" for skin | Silk’s smooth surface and low friction are gentler on skin and hair than a coarser fibre. | Claims about collagen, wrinkles or skin repair are cosmetic claims about the wearer, not properties of the cloth, and they are not something a textile can establish. |
| "Naturally antibacterial" | Silk has some natural resistance to certain micro-organisms. | It is not an antimicrobial finish and should not be presented as one. This is where a claim starts to need evidence that most suppliers do not have. |
| "24 momme, so it is the best" | Higher momme is heavier cloth with more body, for the same weave. | Momme is weight, not quality. A 24 momme scarf is the wrong choice for something meant to be light, and it says nothing about the raw filament or the finishing. |
| "Chemical-free" | Silk is a natural fibre and the fibre itself is not synthetic. | Dyeing, printing and finishing all involve chemistry. "Chemical-free" is not a claim a dyed or printed textile can honestly make. |
| "Handmade" | A hand-rolled edge genuinely is skilled hand work, on all four sides. | The cloth is woven on a loom, and most printing is done by machine. "Handmade" is usually describing the finish, not the whole scarf — it is more accurate to say what was done by hand. |
What we put in writing
The test above is the one we hold our own quotations to. Every quotation and sample card carries the same lines, because these are the things that actually determine what the cloth is — and every one of them is something a buyer can check.
- The weave and the momme. These two numbers settle more about the cloth than anything else on the page.
- The format, in centimetres.
- The printing method, and how many colours the artwork carries.
- The edge finish, named as hand-rolled and hand-stitched, or as a machine hem.
- The packing, quoted as its own line so it does not disappear inside the unit price.
- The minimum order quantity and the production lead time — stated as weeks after sample approval, not as a date we cannot hold.
- A physical sample before bulk production, on the actual weave and momme you have chosen.
- A colour-matching step during sampling, where brand colour accuracy matters.
- Photographs of the finished order before it ships.
That is the whole list. It is short, and it is the one a buyer can work with.
Questions we are asked about silk claims
What does 5A or 6A silk actually mean?
It is a grade applied to raw silk filament, describing its quality before weaving. It is not a grade of the finished scarf, and a scarf carrying the letters does not thereby carry the raw silk that earned them. If a grade matters to your specification, ask for the traceability behind it.
Is mulberry silk really better than other silk?
Mulberry silk is the finest and most uniform commercial silk, and it is what we work in. Tussah and eri silks come from other species and behave differently — coarser, warmer in tone, sometimes spun rather than reeled. "Better" depends on what the cloth has to do.
Is higher momme better?
No. Momme is the weight of the cloth. Heavier is better for a scarf that should hold a knot and carry a print with depth; lighter is better for a scarf that should be airy. It is a fit question, not a quality ranking.
Can silk be called chemical-free?
Not honestly, if it has been dyed or printed. The fibre is natural, but dyeing, printing and finishing involve chemistry. What can be said accurately is that silk is a natural protein fibre that biodegrades, and that we can describe the processes used.
What should I ask a supplier to prove a silk claim?
Ask what the claim is about — the fibre or the cloth — and what evidence sits behind it. For weave and momme, the answer is a specification. For a raw silk grade, it is traceability to the reeling house. For a skin or antibacterial claim, it is usually nothing, which is the useful thing to find out.
Where to go next
For the fibre itself, what silk is. For the case for silk that does survive scrutiny, why silk — including a section on what silk does not do. For how to check a scarf in your hand, how to tell if silk is real. And for how these claims land on a unit cost, what your unit cost buys.
