Preparation process of worsted knitting yarn anti-fuzzing and anti-pilling yarn

Abstract

The invention belongs to the technical field of textile, and particularly relates to a preparation process of worsted knitting yarn anti-fuzzing and anti-pilling yarn, which specifically comprises the following steps: enhancing the yarn stability through a three-time cyclic yarn steaming method, under the action of steam, enabling wool fibers to absorb moisture and expand, weakening the intermolecular acting force, enabling the fibers to become loose, enabling the surfaces of the fibers to be smoother, and improving the anti-fuzzing and anti-pilling performance of the fibers. And hairiness is reduced. The yarn structure is more stable through the low-speed, small-drafting and strong yarn steaming technology, so that wool yarn hairiness is reduced, the anti-pilling performance is improved, the product appearance and durability are improved to meet the requirements of consumers, the market competitiveness is enhanced, the replacement frequency of clothes can be reduced, data waste is reduced, the concepts of environmental protection and sustainable development are met, and the yarn is worthy of popularization and application. In the yarn steaming process, the steam can release the internal stress of the fibers, curling and twisting of the fibers are reduced, the yarn structure is more stable, front guard arrangement is more orderly, the yarn surface is smoother, and the yarn is more durable and not prone to fuzzing and pilling.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textiles, and in particular to a worsted knitting yarn anti-pilling yarn preparation process. BACKGROUND

[0002] Wool spinning is a production process of yarn made of animal hair such as wool, cashmere, rabbit hair and hair-type chemical fibers through spinning process. The products have the characteristics of warmth and moisture absorption, and are widely used in the fields of clothing, carpet and industrial cloth.

[0003] With the development and progress of society, the traditional wool spinning knitting yarn product cannot fully meet the needs of people's life in appearance and use performance. Modern consumers have higher and higher quality requirements for textiles, and the anti-pilling performance has become one of the important indicators of the quality of textiles. In order to improve product quality, enhance wearing comfort and prolong service life, it is necessary to reduce the hairiness of yarn, improve product stability and improve the anti-pilling performance.

[0004] Therefore, the present application provides a worsted knitting yarn anti-pilling yarn preparation process to solve the above technical problems in the prior art. SUMMARY

[0005] Based on the technical problems in the background art, the present application provides a worsted knitting yarn anti-pilling yarn preparation process.

[0006] The worsted knitting yarn anti-pilling yarn preparation process provided by the present application has the advantages that The process uses Merino superfine wool (19.5mic, TEC treatment); The process flow includes: Front spinning: In order to improve the uniformity of the yarn, the front spinning is run at a low speed, specifically, the gilling is 150 m / min, the roving machine is 120 m / min, and the accidental draft is reduced as much as possible to ensure the uniformity of the sliver; Spinning: Small draft (draft is about 15 times) is used on the (Aozawa 451) spinning machine, which is beneficial to reduce the spinning breakage rate and improve the sliver level of the yarn; Yarn steaming: The yarn steaming process is a key process flow for improving the anti-pilling performance of the present application. The yarn steaming process is to strengthen the stability of the yarn through three-cycle yarn steaming method. The three-cycle yarn steaming method is as follows: The preheating temperature is designed to be 60℃ / 5min, the vacuum degree is 85%, and the temperature is 80℃ / 6min for setting; Through three times of circulating steaming, yarn stability is enhanced, under the action of steam, wool fiber absorbs moisture and expands, intermolecular force is weakened, fiber becomes relaxed, at the same time, fiber surface is smoother, hairiness generation is reduced, in the process of steaming, steam can also release the internal stress of fiber, reduce fiber curling and twisting, make the yarn structure more stable, avant-garde arrangement more orderly, yarn surface more smooth, make it more durable, not easy to fuzz and pilling; Winding: use Swiss LOEPFE clearer hair function to detect the hairiness value of each yarn in the winding process, if the hairiness value exceeds the set value, the electronic clearer will automatically clear the related yarn to ensure that the hairiness of all yarns is within the set hairiness value range; Double twisting: before the double twisting batch, the winding ball should be balanced for twelve hours to further release the internal stress of the yarn; Steaming: after the double twisting, the double twisted yarn is steamed again to balance the twist direction of the yarn; Packaging: packed into the warehouse.

[0007] Compared with the prior art, the present application provides a worsted knitting yarn anti-fuzzing and pilling yarn preparation process, which has the following beneficial effects: Through low speed, small draft and strong steaming process, the yarn structure is more stable, thereby reducing the hairiness of wool yarn, improving the anti-fuzzing and pilling performance, improving the appearance and durability of the product to meet the requirements of consumers, enhancing the market competitiveness, reducing the replacement frequency of clothes, reducing material waste, meeting the concept of environmental protection and sustainable development, wherein through three times of circulating steaming, yarn stability is enhanced, under the action of steam, wool fiber absorbs moisture and expands, intermolecular force is weakened, fiber becomes relaxed, at the same time, fiber surface is smoother, hairiness generation is reduced, in the process of steaming, steam can also release the internal stress of fiber, reduce fiber curling and twisting, make the yarn structure more stable, avant-garde arrangement more orderly, yarn surface more smooth, make it more durable, not easy to fuzz and pilling.
