Weaving method of cotton-vinylon blended hollow yarn home textile fabrics

Abstract

The invention relates to a weaving method of cotton-vinylon blended hollow yarn home textile fabrics. The method comprises steps of 1) of water-soluble polyvinyl alcohol spinning, the polyvinyl alcohol is spun through a dry spinning method, the polyvinyl alcohol solution with the concentration of 30-40% is made to flow through a spinning device and is pressed into a hot air passage from small holes of a spinning jet, and the hot air is utilized to evaporate the water of the polyvinyl alcohol solution so that the polyvinyl alcohol solution is made to coagulate into filament fiber in fine flow;2) of spinning of core-spun yarns; 3) of weaving, pure cotton yarns and the core-spun yarns obtained in the 2) are subjected to sizing at the temperature of 50-75 DEG C, and the fabrics are woven at intervals; and 4) of desizing and vinylon-dissolving, the fabrics obtained in the 3) are simultaneously subjected to desizing and vinylon-dissolving, the desizing liquid is kept for 30-45 minutes at the temperature of 90-98 DEG C, and the fabrics after complete desizing and vinylon-dissolving are obtained. The weaving method is advantaged in that good vinylon-dissolving of the core-spun yarns and high yarn strength in the weaving process are achieved.

Description

technical field [0001] The invention relates to a weaving method for a home textile fabric, in particular to a weaving method for a cotton and vinylon blended hollow yarn home textile fabric. Background technique [0002] Water-soluble vinylon is easily soluble in water, easy to degrade, odorless and non-toxic, and has been widely used in traditional textiles, medical treatment, papermaking, non-woven fabric development, disposable product production, embroidery base fabric production and other fields. [0003] Hollow yarn is the application of hollow fiber concept in yarn. Water-soluble vinylon and cotton fiber are used as core-spun yarn, and the core yarn of vinylon is dissolved in hot water to form pure cotton hollow yarn. This greatly increases the volume content of stored air in the yarn. The yarn core in the hollow yarn is melted away, and the quality is reduced, which can realize the thinning and specialization of the yarn and the lightness and thinning of the home t...

Problems solved by technology

However, it uses water-soluble vinylon staple fiber for sliver mixing, and the hollow effect of the yarn is not obvious and easy to collapse after fiber removal

[0005] Another example: the invention patent with the application number of 200710019777.2 discloses a soft and warm hollow yarn producer. First, the selected cotton fibers are processed, including cotton blending, carding, drawing, combing, drawing, roving, The process of spinning, winding, and loosening; secondly, selecting water-soluble fibers as blended fibers, and then processing the selected water-soluble fibers. The steps include at least cleaning and carding; although the products produced have Many advantages, but the processing procedure is too complicated and the production efficiency is low

[0006] For another example, the invention patent with the application number 201210371990.0 discloses a high hollowness core-spun yarn spinning process, the core-spun yarn obtained and the towel weaving process using the core-spun yarn, which combines two coarse cotton yarns with a number of 4.1 to 7.3 tex water-soluble vinylon filaments are compound twisted to produce spun yarns coated with cotton fibers; then the water-soluble vinylon filaments are hydrolyzed to obtain the high hollowness core-spun yarn; The disadvantage of this method is: the hollow effect of the obtained fabric is easy to collapse during use, thus weakening the excellent performance of the hollow yarn
