Abstract

The invention relates to a method of yarn bundle-shape continuous back-flow silkete, which includes the following steps: 200 to 1000 billet yarns are combined into a yarn bundle, and 1 to 36 yarn bundles are arranged for parallel running; the 1 to 36 yarn bundles continuously run on a silkete machine set and sequentially pass through an immersing and rolling alkali tank 1, a ventilating drum 1, an immersing and rolling alkali tank 2, a ventilating drum 2, an alkali-removing steam box, an alkali-removing eluting tank, a water scrubbing tank 1 and a water scrubbing tank 2 to fall into a yarn container in a wet-yarn type. The method of yarn-bundle-shape continuous back-flow silkete realizes the continuous production of yarn silkete, reduces sewage discharging amount, has the yarn-bundle running of the yarn, high production efficiency, uniform silkete quality and high yarn utilizing rate, enables the yarn silkete to be the normal preprocessing technology, and is helpful for improving the product grade of yarn dyed fabric and knitted fabric.

Description

technical field [0001] The invention belongs to the field of yarn pretreatment technology, in particular to a method for continuously reflowing and mercerizing yarn bundles. Background technique [0002] Yarn pretreatment and dyeing is an important process in the deep processing of textiles. The grade of dyed fabrics made from dyed yarns is higher than that of textiles that are woven first and then dyed. Therefore, dyed fabrics occupy a considerable share in the domestic and foreign textile fabric markets, especially in the high-end product market. my country is the world's largest producer of dyed fabrics, so the production capacity of yarn pretreatment and dyeing is huge. So far, most of the mercerizing of pure cotton and cotton / polyester and cotton / linen blended yarns adopts skein mercerizing, which belongs to the intermittent production mode, and has the problems of uneven mercerizing, low labor productivity, high labor intensity, and high water, electricity and steam c...
