A kind of production method of high-count spun silk yarn

Abstract

The invention discloses a high-count spun silk yarn production method. The method includes the following steps that raw materials are prepared, and spun silk yarn is cut into fibers ranging from 28 mm to 30 mm in length in a crush cutting mode; then the spun silk yarn is put into conditioning fluid according to the weight ratio of 1 to 10 of the conditioning fluid, processing is conducted for 30-50 min at the room temperature, then the spun silk yarn is cleaned with clear water, drying and enzyme deactivation are conducted, and the water spray moisture regain is controlled to be 14%-18%; the conditioning fluid contains, by weight, 1%-1.2% of tea saponin and 0.8%-1.5% of papain; the obtained silk bags are further processed into spun silk coarse yarn, and then the obtained spun silk coarse yarn is directly fed into a four-roller three-section drafting ring throstle improved in a grid ring type compact spinning mode to spin the high-count spun silk yarn. Through the high-count spun silk yarn production method, the preprocessing technology is further optimized, the papain is fully utilized to process the spun silk raw materials in cooperation with tea saponin, and by means of the method, excellent spun silk yarn extremely low in hairiness and great in breakage strength can be produced at a time.

Description

technical field [0001] The invention relates to a production method of high-count spun silk yarn, which belongs to the field of textile processing. Background technique [0002] Spun silk is a kind of natural protein fiber with good tensile properties. The fiber is thin, soft, smooth, elastic, and elegant in luster. Its fabric has smooth handle, good drapability, warmth retention and good moisture absorption and release And other characteristics, belong to high-grade textile fabrics. 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...

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

[0003] The prior art discloses a spinning method for spinning high-count spun silk yarns on cotton spinning equipment. It is mainly improved from the textile technology, and a big breakthrough has been made, but the spun silk yarns produced still have relatively hairiness. many questions
