How To Distinguish Silk Clothes?

We all know that silk clothes have many advantages, but what if we buy counterfeit goods? In the following article, we will introduce the method of identifying silk for you.

1. Price identification method

The price of silk fabrics is relatively expensive, about twice that of chemical fiber and imitation silk fabrics, but not all expensive ones are silk, this is just a recognition factor, and it is still necessary to identify and judge from multiple perspectives.

2. Luster and feel identification method

Silk has a slight grip and feels smooth to wear. Ordinary synthetic fabrics do not possess this characteristic. Some good rayon can also achieve a smooth texture, but cannot achieve the straightness of silk.

3. By folding in half

Silk has high elasticity and basically does not leave creases. It can be restored to its original state and is smooth as before. However, counterfeit or artificial silk does not have such elasticity, making it prone to creases and unable to restore its original state.

4. Combustion identification method

Take out a portion of the yarn thread and burn it, the silk cannot see the open flame, there is a smell of burning hair, it indicates the presence of protein fibers, the gray particles are black and can be crushed by hand. Simulated silk catches fire and has a plastic smell. After the fire is extinguished, hard rubber blocks will be left at the edges.

5. Tensile force identification method

The tensile strength of silk is poor and it is easy to break. Rayon is prone to breaking when in a moist state. Chemical fibers are relatively strong and tough in both wet and dry conditions.

6. Friction based acoustic recognition method

Rubbing the fabrics against each other produces a "silk chirping" sound, while synthetic fabrics and fabrics made from other materials do not produce this sound.

7.84 Disinfectant identification method

In experiments, chemical methods are usually used to identify: 1 gram of silk scarf fiber is placed in 1 mole of sodium hypochlorite solution. If it is completely dissolved, it can be determined that it is silk. The main component of 84 disinfectant is sodium hypochlorite, which will undergo a chemical reaction of dissolution when encountering protein fibers. In daily life, you can try 84 disinfectant to distinguish between real and fake silk. When using this method, it should be paid to controlling the specific gravity, if the amount of disinfectant is not enough, the concentration is not reached, or some fabrics have a tight structure, they may not be completely dissolved.
