The twisting of cashmere yarn is to make the two sections of the yarn rotate relative to each other. At this time, the fibers in the yarn that are parallel to the yarn axis are inclined into helix. For short fibers, twisting is mainly to improve the strength of the yarn.

The twisting of filament can not only improve the strength of yarn, but also produce some effect. The number of twists and the combination of twist direction and twist in the fabric have a great influence on the appearance and performance of the product.

A cashmere spinning yarn and a manufacturing method thereof are characterized in that the production method comprises the following steps: strip making, first drawing, second drawing, roving and yarn forming. As a modification of the invention, powder antistatic coating can be added to the roving and yarn forming steps.

The manufacturing method of cashmere blended yarn provided by the invention solves the problem of uneven cashmere color blocking in yarn forming; the steps of flower cleaning and carding adopt more carding and less beating, and the powder anti-static coating is added to reduce the damage and falling of cashmere fiber, and solve the problem that cashmere is easy to wind up the cylinder and doff; the powder anti-static coating is added to the spinning process, which solves the problem of skin scratching caused by static electricity Roller and roller phenomenon; increase the twist of roving to overcome the disadvantages of sticking, rotten and loose in the spinning process due to the reduction of cashmere crimp number and the smooth fiber.

The yarn twist of cashmere yarn manufacturer refers to the physical and mechanical properties such as strength, elasticity, elongation, luster and hand feeling of the yarn In fact, the relative angular displacement between the cross sections of the cotton yarn is used to change the yarn structure by making the original straight and parallel fibers and the yarn axis incline. During the twisting process, the thick sliver gradually shrinks from the width, and the two sides gradually fold into the center of the yarn line, forming a twisting triangle. In the twisting triangle, the width of the sliver Degree and cross section change from flat ribbon to cylindrical yarn.
