How to identify silk underwear on the market?

Currently, there is a kind of fabric on the market which looks very similar to silk in texture and also feels quite smooth, yet its price is about two-thirds lower. Today, the Sexy Underwear website will teach you how to identify silk underwear. Generally speaking, silk usually refers to silk produced by silkworms, including mulberry silk, tussah silk, castor silk, cassava silk and so on. Consumers can use the following methods to identify silk fabrics.

1. Identification of silk underwear: Product number identification method.
Domestic silk fabrics adopt a unified product number composed of 5 Arabic numerals. The first digit from the left among these 5 digits represents the material number of the fabric. For pure silk fabrics (including mulberry silk and spun silk), it is "1"; for chemical fiber fabrics, it is "2"; for blended fabrics, it is "3"; for tussah silk fabrics, it is "4"; and for rayon fabrics, it is "5".

2. Identification of silk underwear: Price identification method.
The price of silk fabrics is approximately twice that of chemical fiber and artificial silk fabrics.

3. Identification of silk underwear: Luster and hand-feel identification method.
Spread the sample flat and observe its appearance. Silk has the property of absorbing light. It looks smooth without a mirror-like surface, with an elegant and soft luster, showing a pearl-like shine. It feels soft and flowing, and the silk threads are relatively dense. When grasped by hand, wrinkles will appear. The higher the purity and the greater the density of the silk, the better the hand-feel. Although artificial silk fabrics have undergone softening treatment and feel relatively soft, the fabric surface is dull and has no pearl-like luster. Chemical fiber fabrics have a bright and dazzling luster and feel rather stiff. In addition, silk products should have a slightly scratchy feel. When two layers of fabric are rubbed against each other, a "silk chirping" sound will be produced, while fabrics made of other materials do not have this sound.

4. Identification of silk underwear: Combustion method.
Pull out some yarns and burn them. For silk, there is no open flame, and it gives off a smell like burning hair. The silk ash is in the form of black particles and can be crushed by hand. For artificial silk, when it meets fire, flames will appear, and it has a plastic smell. After the fire goes out, hard edges will be left.
