A kind of silk yarn production process

Abstract

The invention discloses a spun silk yarn production process. Spun silk fiber is made into continuous spun silk sliver by refining, draft making and strip forming procedures of a silk spinning production process; then the spun silk sliver is made into spun silk fine yarn by roving and spinning procedures of a cotton spinning production process; a four-roller double-leather-collar drafting system is adopted in roving and spinning of cotton spinning, and comprises a rear roller, a rear leather roller, a middle-rear roller, a middle-rear leather roller, a middle-front roller, a middle-front leather roller, a front roller and a front leather roller, a feeding roller and a feeding leather roller are additionally arranged behind the rear roller, a first groove is formed in the rear leather roller, a second groove is formed in the middle-front leather roller, during production, spun silk sliver or spun silk rove yarn is pressed and fed into the drafting system between the feeding roller and the feeding leather roller, slips and is fed via a space between the rear roller and the first groove in the rear leather roller, is pressed and fed via a space between the middle-rear roller and the middle-rear leather roller, slips and is fed via a space between the middle-front roller and the second groove in the middle-front leather roller, and finally is pressed and output via a space between the front roller and the front leather roller.

Description

technical field [0001] The invention relates to the new technology field of ring spinning, in particular to a spun silk yarn production process. Background technique [0002] Silk is a natural protein fiber with good tensile properties. The fiber is thin and soft, smooth, elastic, and elegant. Its fabric has a smooth hand, good drapability, warmth retention and good moisture absorption and release properties. And other characteristics, belong to high-grade textile fabrics. Silk yarn is generally spun on silk spinning equipment, commonly known as "long spinning". Its production process is long, the scale of labor is large, and the production cost is high, which leads to the high market price of silk yarn and the lack of competitive advantage in the product market. At the same time, due to the relatively poor level of current silk spinning production equipment and process technology, the silk yarn produced by the company is mainly low-count silk yarn, and the surface of the p...

Problems solved by technology

Spun silk yarn is generally spun on silk spinning equipment, commonly known as "long spinning". Its production process is long, the scale of labor is large, and the production cost is high. As a result, the market price of spun silk is expensive, and it lacks the competitive advantage of the product market.

At the same time, due to the relatively poor level of current silk spinning production equipment and technology, the spun silk produced by the company is mainly low-count spun silk yarn, and the spun silk yarn produced has more hairiness on the surface, so it is processed in the subsequent process It also needs to go through multiple singeing processes, which not only causes waste of raw materials, but also expands the product processing process, further increasing the production cost of the enterprise
