Method of identification of silk

“I have a Liberty of London nightgown ready for my shop and really can’t decide whether it is silk or not. Anyone got any foolproof ways of identifying real silk? I’ve read a little about the burn test but before I see whether there’s a bit of fabric I can snip out has anyone got any other ways of telling? Thanks.”

A netizen asked for help online.Many enthusiastic netizens replied that best bet is the burn test.

Customers have big doubts about its purity when they want to buy 100% natural silk home. Therefore, there are a number of ways for reference which can be used together to try to determine if a fabric is genuine silk or a synthetic man-made fabric that looks like silk.

  • No doubt about it – genuine, Real silk usually costs at least ten times as much as synthetics to produce.
  • It is a result of the combination of threads of different single colours in each of the weft and warp. This “shot” effect gives a surface that “shines” and appears to change colour as the angle of light on it changes.
  • Silk can be hand-woven or machine-woven. Machine-woven silk will have a perfectly even weave with no flaws … and very little character. Hand-woven silk has its own individual characteristics. Each piece is unique.
  • In the final.Genuine silk with a woven pattern will have the pattern visible on both sides but the pattern on the reverse side may appear slightly “fuzzy”. Burn Test.This is not a standard test you should perform on silk! However, it is a fairly definitive test.

Genuine silk will burn with a smell like burnt hair and will produce a black, powdery ash. It will only burn while the flame is being applied – take the flame away and the threads will stop burning.

A synthetic fabric will burn with a smell like burning plastic and will drip, form a black ball of residue (not ash), and produce black smoke. It will continue to burn even after the flame is taken away.

Hope we can help you more or less.

Identify Real Silk

1. Flames:

– Genuine quality silk: Burning genuine silk produces a smell very similar to that of burning human hair. The flame is close to invisible when burning the edge of the real silk fabric. Very soon after the flame source is taken away from the fabric, the silk will self-extinguish.
– Fake silk: Most fake silk are in fact petroleum based polyester products. When burned, these materials tend to combust rapidly in intense flames, and give a smell of burning plastic.

2. Ashes

– Genuine silk: The ash from burning is black, crispy and turns to powder easily when grinded.
– Fake silk: The ash of fake silk tend to be sticky, twisted, and difficult to break apart.
