Take the cashmere sweater to the light, and check the density of the cashmere sweater under the light to ensure that the lines are clear and tidy, and it is not easy to expose. If the cashmere sweater is of poor quality, loose density and chaotic texture, it is easy to transmit light.

Real cashmere sweaters generally contain more than 95% cashmere, and the higher the density, the light transmittance is an important index to test the quality of cashmere sweaters.

Step 2 consider

Check the weight of cashmere sweater by hand. Cashmere sweaters are not too heavy, but too light consumption may be discounted and the manufacturing density is not enough. If it is too heavy, it may be mixed with too much wool.

Step 3 touch your hand

The surface feel of cashmere sweater is finer than ordinary wool, and the average fineness is between 14- 16um, which is silky and quite comfortable. Some fake cashmere sweaters may feel slippery, but if they are rubbed with two fingers, it is probably because of talcum powder.

Step 4 look at flexibility

Grasp the cashmere sweater in the palm of your hand and test its elasticity. Because wool has medulla, it is solid and has poor elasticity, while cashmere sweater's wool is hollow and has no medulla, so it is as elastic as glutinous rice board.

Step 5 burn with fire

When a real cashmere sweater burns, it will not only have the burnt smell of protein and flint, but also burn slowly, and the burnt ash will be powdery and will be broken when touched. Although wool has this smell when it burns, because it contains chemical fiber, the ashes will slowly shrink into a ball when it burns.
