Problems solved by technology

At present, domestic research on hemp blended fabrics mostly focuses on the development of hemp / cotton blended fabrics, and there are also related researches on the development of hemp / tencel blended fabrics, but these products have low strength and are difficult to meet the requirements of denim clothing or work clothes. According to the requirement of milling, the invention patent with authorized notification number CN106906546B discloses a production method of blended yarn. method, the blended yarn is supple, moisture-absorbing and breathable, but this invention only achieves a unique style through the change of raw materials, the practical range is not wide, and it is not suitable for the production of denim clothing or work clothes. The yarn hardness in this invention Good wear resistance is low, strong hygroscopicity, easy to mold, antibacterial and mosquito repellent effect is small

Embodiment 1

[0025] A preparation process of high-count hemp blended cotton yarn is characterized in that: it comprises the following process steps:

[0026] S1 cleaning process: After the high-count hemp fiber raw material and cotton fiber are put into the groove, they pass through the A002D cotton grabbing machine respectively, and then pass through the FA035 mixed cotton opener→A045B cotton condenser→A076C single-hand roll machine to make high-count hemp Cotton blended fiber roll; the speed of the large hand of the opener is controlled at 500r / min, and the blending ratio of high-count hemp fiber and cotton fiber is 1:1.8;

[0027] S2 Hydrophobic treatment: carry out hydrophobic modification after the mixed cotton is mineralized;

[0028] S3 carding process: high-count hemp blended fiber rolls are made into raw sliver on the A186G carding machine;

[0029] S4 drawing process: the high-count hemp mixed cotton raw sliver is merged in two ways on the FA306 draw frame, and the head is combi...

Abstract

The invention belongs to the technical field of spinning methods, and particularly relates to a preparation process of high-count hemp and blended cotton yarn. The process comprises the following process steps of S1, cotton cleaning; S2, hydrophobic treatment; S3, cotton carding; S4, drawing; S5, roving; and S6, spinning. High-count hemp and cotton fibers serve as main raw materials and are mixed according to requirements through the steps of mixing in a certain proportion, slivering, drawing and the like through cotton spinning and cleaning equipment, roving, spinning and spooling are conducted to form yarn, and then two-for-one twisting is conducted to form thread; the blended cotton fibers subjected to hydrophobic modification after material mixing can be effectively hydrophobic; the mineralization treatment can enable the yarn to be more stiffened and wear-resistant; and the yarn is low in cost and suitable for manufacturing various work clothes.

Description

technical field [0001] The invention belongs to the technical field of spinning methods, in particular to a preparation process of high-count hemp blended cotton yarn. Background technique [0002] New natural raw materials, pollution-free dyeing materials, pollution-free technology, and health-care raw materials are the main direction of the development of the textile industry. As a kind of natural cellulose fiber, hemp has attracted people's attention in its processing and utilization, especially its structure and characteristics, which are the focus of its research. At present, domestic research on hemp blended fabrics mostly focuses on the development of hemp / cotton blended fabrics, and there are also related researches on the development of hemp / tencel blended fabrics, but these products have low strength and are difficult to meet the requirements of denim clothing or work clothes. According to the requirement of milling, the invention patent with authorized notificati...
