Problems solved by technology

[0003] However, vinylon fiber has the following problems: vinylon fiber is fluffy, has few crimps, and the cohesion force between fibers is small. It is easy to generate a lot of static electricity during spinning, and the spinnability of the fiber is poor.

Abstract

The invention relates to a method for producing high-count yarns from vinylon and polyester fibers, and cotton by blending. Vinylon and polyester, and cotton fibers are selected. Vinylon and polyester fibers are blown, carded and pre-doubled, and then combined with cotton combed silvers on drawing, and cone yarns are produced through procedures of roving, spinning and spooling. Low speed, multi-combing and less-beating, large gauge, small-feeding and less-falling, weighing and pressurizing are adopted in a blowing procedure; large gauge, small noil, big ration, full transfer and proper combing are adopted in a cotton carding procedure; large gauge, big ration, low speed, first-pass pre-doubling and second-pass mixed drawing processes are adopted in the drawing procedure so that components are mixed uniformly; large gauge, big ration, heavy pressurizing, low speed and small twist are adopted in the roving procedure; moderate twist coefficient and low spindle speed processes are adopted in the spinning procedure. The vinylon is added in a polyester-cotton fabric, so that the polyester-cotton fabric has good moisture absorption and good gas permeability, is firm and durable, and resists acid and base, corrosion, moth damage and solarization; high-quality fine staple cotton is added in the polyester-cotton fabric, so that the polyester-cotton fabric is comfortable and soft to wear, keeps warm in wearing, and is suitable for making work clothes.

Description

technical field [0001] The invention relates to a method for producing high count yarn by blending vinylon, polyester fiber and cotton. Background technique [0002] Vinylon is the trade name of polyvinyl acetal fiber, also known as Vinylon. Its performance is close to that of cotton, known as "synthetic cotton", and it is the most hygroscopic variety among existing synthetic fibers. Vinylon was made in Germany in the 1930s, but it is not resistant to hot water and is mainly used for surgical sutures. In 1939, the heat treatment and acetalization method was successfully studied, which made it a fiber with good hot water resistance. The raw materials for producing vinylon are easy to obtain, the manufacturing cost is low, and the fiber strength is good. In addition to being used for clothing, it also has various industrial uses. Vinylon and cotton are blended to produce muslin, poplin, corduroy, underwear, canvas, tarpaulin, packaging materials, work clothes, etc. The fab...
