1. Hand feeling: Pure wool fabrics usually feel soft and smooth, long-haired fabrics are smooth and smooth to the touch, and have a tingling sensation against the wool, while blended or purified fiber products are not soft, some are too soft and loose, and sometimes Sticky.
2. Look at the color: the color of pure wool fabrics is natural and soft, bright and without old feeling. In contrast, blended or purified fiber fabrics have darker gloss or flashing color.
3. Look at elasticity: hold the material tightly by hand, and then release it immediately to see the elasticity of the fabric. The pure wool fabric has a high resilience rate and can quickly return to its original state, while blended or chemical fiber products have poor wrinkle resistance, and most of them have relatively low wrinkle resistance. Significant wrinkles or slow recovery.
4. Identification by burning method: Take a bunch of yarn and burn it with fire. The smell of pure wool fiber is like burning hair, and the smell of chemical fiber fabric is like burning plastic. The harder the burning particles, the more chemical fiber composition.
