How to identify silk?

It is well-known that silk is premium and luxurious, and its super elegance makes it attractive for those looking for a quality life.

However, when confronted with hundreds of so-called “silk goods” displayed either online or in brick-and-mortar stores, it is a headache to tell which ones are real for an inexperienced person.

Luckily, there is a list of ways to help you identify genuine silk. 

  • Price

  • Lustre

  • Weave

  • Pattern

  • Hand touch

  • The burn test



Pure silk is always expensive than synthetic fabrics, such as satin. Satin looks similar to silk, while they are essentially different. Silk is a natural fiber, and satin is a synthetic fiber. As a result, satin products are usually 4-10 times cheaper than silk products, depending on silk’s types and brands.

Because of its triangular prism-like structure of silk fibers, silk shimmers and reflects multicolors from different angles of light, while synthetic fibers only shine white no matter what the angle of light falling on it.

Silk can be either hand-woven or machine-woven. Hand-woven silk is more natural-looking, and every piece is unique because there are minor variations in the evenness of the texture. While machine-woven silks look perfectly even and all rolls are the same. 

Most synthetic fabrics are machine-woven, yet some fake silk fabrics are woven on purpose to look natural with tiny imperfections.

Printing and weaving are two commonly used ways to add patterns onto silks. A printed pattern is visible on one side and a silhouette on the reverse side. A woven pattern is visible on both sides, but the design on the reverse side appears slightly blurred.

Regarding synthetic fabrics, only the printed pattern is available. And the design could only be seen on the printed side.

Hand touch

If you touch the genuine silk with your hands, it will have three features.

  1. You could get the same wonderful feeling as you gently rub your kitty’s hair, or the chocolate melting in your mouth.
  2. It will become warm by rubbing. With other fabrics, it is impossible to experience warmth.
  3. You could hear a crunching noise if you scrunch it up a bit in your hand.

The burn test

If you have a silk swatch on hand, we recommend this method because it is the most definitive test to distingue genuine silk. There are three differences when burning pure silk and synthetic silk.

  1. Smell: Burnt pure silk smells like burnt human hair, while fake silk smells like plastic.
  2. Flame: Burnt pure silk has no flame, and it will stop burning once the fire is removed, while fake silk stays on fire.
  3. Ash: Burnt pure silk will crush into black ash, while burnt fake silk forms a molten glob, no ash produced.
