1. Check the texture

The real woolen sweater is soft, elastic, feels good and keeps warm; The texture, elasticity, feel and warmth retention of fake sweaters are poor.

2. Burning test

Real wool contains a lot of protein. Take a few fibers from the clothes and light them, smell them and look at the ashes. If there is the smell of burnt feathers, the ashes will be crushed with your fingers, which is pure wool; If there is no smell of burnt feathers and the ashes are not crushed and caked, it is a chemical fiber fabric.

3. Friction electrostatic inspection

Rub the clothes to be inspected on the cotton shirt for about 5 minutes, and then quickly separate from each other. If there is no "snapping" sound, it is a real sweater; If there is a "snapping" sound, even with electrostatic sparks, it is a chemical fiber fabric, not a fake sweater.
