Preparation method of vortex spinning brocade yarn

Abstract

The invention relates to a production method of vortex spun colored silk yarns and belongs to the technical field of production of special yarns. The method includes: selecting materials, premixing slivers, pre-drawing, and performing vortex spinning. Colored viscose fiber and a plurality of flat polyester fibers different in color are pre-mixed; namely, the colored viscose fiber and the flat polyester fibers are alternately disposed in a disc grille of a cotton mixer, the fibers and the grille are fed into a carding machine after opening and are fed into a drawing frame for pre-drawing by the carding machine so as to obtain mixed slivers; the flat polyester fibers and the colored viscose fiber are made into polyester slivers and viscose slivers respectively before drawing and vortex spinning; the obtained fabric has the advantages of colorfulness, diversity, wear resistance and the like.

Description

technical field [0001] The invention relates to a preparation method of vortex spinning brocade yarn, which belongs to the technical field of preparation of special yarns. Background technique [0002] With the development of textile technology, different spinning forms can form different yarn styles due to different spinning principles. The vortex spinning process is short and the production rate is high. At the same time, it can save a lot of labor and is easy to operate. It is also relatively simple, and the strength and uniformity of the spun yarn are better than those of conventional technology. Not only can core-spun yarns be produced, but also double-structured yarns can be produced by using different fiber lengths and shrinkage degrees. Rich and colorful special yarn, so it is widely used. However, since vortex spinning yarns are generally pure viscose yarns and polyester-viscose blended yarns, the proportion of colored cotton or pure polyester yarns, pure cotton ya...

AI Technical Summary

Problems solved by technology

However, since vortex spinning yarns are generally pure viscose yarns and polyester-viscose blended yarns, the proportion of colored cotton or pure polyester yarns, pure cotton yarns and other wool yarns should not be too high, such as pure cotton Generally, the proportion of spinning should not exceed 40%, otherwise the spinning efficiency will be affected due to poor spinnability; at the same time, air-jet vortex spinning uses high-speed compressed air to form yarns, and the speed is more than 20 times that of traditional spinning, generally up to 380 meters per minute, so the influence of temperature and humidity is particularly sensitive, the viscose type is controlled at 50-60%, and the polyester-viscose blended type is controlled at 40-45%, so the requirements for the type of fiber and the air-conditioning environment are relatively strict, which limits product development. further development of
