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

Embodiment 1

[0020] The spinning method of the 240Nm spun silk yarn of the present embodiment, comprises the steps:

[0021] Step 1: Pretreat the spun silk fiber raw material, and use the GYFA311D fiber stretcher to cut the spun silk into fibers with a length of less than 40mm. The average length of the spun silk fiber after stretching is 30mm, which is suitable for processing on cotton spinning equipment .

[0022] Step 2: Based on the weight of the spun silk raw material obtained in the first step, spray 0.33% CAS antistatic agent aqueous solution and 11% water to the spun silk raw material according to the weight percentage, and let it stand for 30 hours to balance and control the moisture regain at 16%.

[0023] Step 3: Put the silk bags obtained in the first two steps on the cotton opening and cleaning equipment for opening and mixing. The beater speed is 465r / min, the beater speed of A076C coiler is 770r / min, and the fan speed is 1500r / min.

[0024] The fourth step: card the silk ...

Embodiment 2

[0033] The basic steps of the spinning method of the 300Nm spun silk yarn of the present embodiment are the same as in Example 1, but the specific process parameters of each step are different, specifically as follows:

[0034] Step 1: Pretreat the spun silk fiber raw material, and use the GYFA311D fiber stretcher to cut the spun silk into fibers with a length of less than 40mm. The average length of the spun silk fiber after stretching is 31mm, which is suitable for processing on cotton spinning equipment .

[0035] The second step: based on the weight of the silk raw material obtained in the first step, spray 0.3% CAS antistatic agent aqueous solution and 13% water to the silk raw material according to the weight percentage, and let it stand for 32 hours to balance and control the moisture regain at 17.5%.

[0036] Step 3: Put the silk bag obtained in the first two steps on the cotton opening and cleaning equipment for opening and mixing treatment. The main process paramete...

Abstract

The invention relates to a method of spinning high-count spun silk yarns; the method comprises the steps: pretreatment of spun silk fiber material; spraying of antistatic agent and water; cotton opening and cleaning procedure; cotton carding procedure; preparation procedure for combing; combing procedure; drawing procedure; roving procedure and spinning procedure. The production cost of spun silks in the present spun silk enterprises is very high and the produced spun silk products are lack of competitiveness; in order to solve the problems, the method of spinning the high-count spun silk yarns in cotton spinning equipment is searched in the combination of the characteristics of the spun silk fiber material; and finally, the high-count spun silk yarns with yarn fineness of 240-300Nm are spun on a four-roller and three-section draft ring spinning machine modified by grid ring type compact spinning; the method not only changes the situation that the present silk spinning equipment is only capable of spinning low-count spun silk yarns, but is improved in the utilization of the spun silk material; the competitive advantage of the spun silk products in the market is promoted and the benefits are brought to enterprises.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a spinning method of high-count spun silk yarn. 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 ya...
