First of all, the composition of clothes can be preliminarily judged by observing the composition list marked on the clothes. For example, some composition lists will indicate the cotton content, etc. The following figure is the composition list of clothes. However, the ingredient list may not really reflect the ingredients of clothes, and many fakes will sell dog meat, so some common sense of fabric identification is needed to help identify the ingredients of clothes.

The following are the identification methods of various fabrics:

1. Pure cotton cloth: the cloth surface is soft in luster and soft to the touch.

2. Viscose cotton cloth (including artificial cotton and fiber-rich cloth): the cloth surface is soft and bright, bright in color, smooth and smooth, soft to the touch and low in elasticity.

3. Polyester/cotton: The luster is brighter than pure cotton, the cloth surface is flat, and it is clean without yarn ends or impurities. It feels smooth and crisp, and its elasticity is better than pure cotton.

4. Pure wool worsted fabric: the surface of the fabric is smooth and bright, and the texture is fine and clear. Soft and natural luster, pure color. Soft and elastic. Pinch the tweed by hand to loosen it, the crease is not obvious, and it can be quickly restored to its original state. Most yarn counts are double-stranded.

5. Wool woolen cloth: The woolen cloth has a plump surface and a compact and thick texture. There are fine hairs on the surface, and the texture is generally not exposed. Feel warm, plump and elastic. Most of the yarns are coarse count single yarns.

6. Wool-polyester blended woolen cloth: the appearance is pure wool style. The tweed is clear, flat and smooth, not as soft as pure wool fabric, and has a stiff and rough feeling, and its elasticity is higher than that of all wool and wool-bonded wool fabric. Tighten the tweed by hand and release it, and the crease will quickly return to its original state.

7. Real silk: the silk surface is smooth and clean, with soft luster and bright and pure colors. Feel smooth, soft, light and elegant appearance. When the silk surface is dry, it has a pulling feeling when touched by hand, and there is a "silk sound" when it is torn.

8. Viscose silk fabric (rayon silk): The silk surface is bright but not soft, bright in color, smooth to the touch, soft and drape, but not as light and elegant as real silk. When the silk surface is loosened by hand, there are creases, and the recovery is slow. The voice is hoarse when it is torn. After the warp and weft are wet with water, they are easy to break.
