Cashmere is different from wool. Wool grows on sheep and cashmere only grows on goats. Generally speaking, cashmere only refers to cashmere. Sheep don't have cashmere. Many people call the fine wool on sheep, which is somewhat similar to cashmere, as "Cashmere". In fact, they confuse the concepts of cashmere and wool.
The scale arrangement of wool is denser and thicker than that of cashmere, and its shrinkage is greater than that of cashmere; The outer scale of cashmere fiber is small and smooth, and there is an empty air layer in the middle of the fiber, so it is light in weight and feels smooth and waxy.
The crimp degree of wool is smaller than that of cashmere. The crimp number, crimp rate and crimp recovery rate of cashmere fiber are larger. It is suitable for processing into knitwear with fullness, softness and good elasticity. It is comfortable and natural to wear and has good reduction characteristics, especially in the aspects of no shrinkage after washing and good shape retention. Due to the high natural curl of cashmere, it is closely arranged in spinning and weaving and has good holding force, so it has good warmth retention, which is 1.5-2 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, small density, regular circular cross-section, strong moisture absorption, 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. The acid and alkali resistance of wool is better than that of cashmere, and the damage of wool in the presence of oxidant and reductant is less than that of cashmere. The pilling resistance of wool products is better than that of cashmere products, but the shrinkage is large.
