The identification of cashmere and wool
The scales of wool are denser and thicker than cashmere, and its shrinkage is greater than that of cashmere. The scales on the surface of cashmere fiber are small and smooth, and there is an air layer in the middle of the fiber, so it is light in weight and feels smooth and waxy.
The curl degree of wool is smaller than that of cashmere. The number of curls, curl rate and curl recovery rate of cashmere fiber are larger. It is suitable to be processed into knitwear with full, soft and elastic feel. It is comfortable and natural to wear and has good elasticity. Restoration properties, especially in terms of non-shrinkage after washing and good shape retention. Because cashmere has a high natural curl, is tightly arranged during spinning and weaving, and has good cohesion, it has good warmth retention, which is 1.5 to 2 times that of wool.
The fineness unevenness of cashmere is smaller than that of wool, and the appearance quality of its products is better than that of wool. Cashmere fiber has uniform fineness, low density, mostly regular circular cross-sections, strong hygroscopicity, can fully absorb dyes, and is not easy to fade. .
The density of cashmere is smaller than that of fine wool, and its products are lighter and thinner than wool products. Wool’s acid and alkali resistance is better than that of cashmere, and it is less damaged than cashmere when encountering oxidants and reducing agents. Wool products have better pilling resistance than cashmere products, but they have greater shrinkage.
The main types of counterfeit cashmere products on the market are: the cashmere content is seriously insufficient, which is not enough to achieve the warmth-keeping effect of cashmere products; the second is to pass it off as good, using fine wool instead of cashmere. Generally, the fineness of cashmere is between 13.5 microns and 15.5 microns. microns, and wool is larger than this data. lTtkUy
