How to identify polyester yarn?

1. Soft and delicate texture

Rayon has poor tensile properties and is easily broken after being stretched; moreover, the rayon feels rough and clammy and feels clammy and cold. After clenching it tightly, there are many wrinkles, and even after it is flattened, there are still lines. Take out the cloth and wet it. The elasticity is different when wet and dry. The characteristics of silk and rayon are opposite. The silk has a soft luster but soft to the touch, and the texture is delicate but can make a special sound of "silk ming" or "silk ming" when rubbing against each other. After clenching it tightly with your hands, the wrinkles are less and less obvious, and the silk has the same elasticity in dry and wet. The popular polyester yarn rebounds quickly, has good anti-wrinkle properties, is strong and not easy to break, and is highly reflective.

2. Bright and elegant gloss

If the polyester silk, which is popular with customers, is expanded to observe the appearance, one can see that it is smooth, elegant and bright. The higher the purity of wrinkles on the hands, the more densely arranged silk threads can be seen when looking closely at the silk. The fine and well-received polyester yarn is soft to the touch after debonding treatment, but the silk surface is darker and has no pearl luster; the chemical fiber fabric is bright and dazzling and has a hard hand.

3. Combustion method

Several groups of silk fabrics can be selected by burning. Burning silk will not have an open flame, but it has a plastic smell, and rubber blocks will be produced; silk fabrics such as burning silk will not have obvious rubber blocks, but Polyester DTY and the like will appear black small particles. Be careful with fire if you are going to try this method.
