Problems solved by technology

[0004] In addition, in the field of warp knitting, due to the high speed and large output of the warp knitting machine, it is only suitable for filament weaving.
Although spun yarns such as cotton, tencel, and modal have good wearability, due to problems such as low strength, small elongation, and many hairiness, the yarn is easy to break during the warp knitting process, and the machine speed is difficult to reach the normal level. Low efficiency, so it is rarely used in warp knitting, thus limiting the development of warp knitted fabrics to diversification and high-grade

Abstract

Provided is a method for producing slurry-free self-sizing fabric containing low-melting fiber yarn. The method for producing the slurry-free self-sizing fabric containing low-melting fiber yarn is characterized in that the method includes the following steps of opening and cleaning cotton, carding, drawing, roving, spinning, winding, warping, yarn thermal bonding and weaving; for opening and cleaning the cotton, main fibers and low melting point fibers conduct disc mixing to be made into cotton rolls; for carding, the rolls with the main fibers and the low melting point fibers mixed well arecombed, the fibers are separated into a single state to form silver blended with the main fibers and the low melting point fibers; for drawing, the blended sliver is blended through a drawing machinewith low melting point fiber mass percentage to be 5-35% and the main fiber mass percentage 65-95% to prepare mixed drawn sliver. With a certain proportion of the low melting point fibers added to thefibers during spinning, yarn containing the low melting point fibers heated during subsequent processing, and low melting point fibers melted as an adhesive for the yarn, the method for producing theslurry-free self-sizing fabric containing the low-melting fiber yarn has the advantages of improving the strength and wear resistance of the yarn and attaching hairiness, and improving yarn weavability with no use of slurry.

Description

technical field [0001] The invention relates to a method for manufacturing a size-free self-sizing fabric containing low-melting fiber yarn, which belongs to the technical field of textiles. Background technique [0002] With the development of economy and society, people pay more and more attention to environmental issues. The pollution caused by the textile printing and dyeing industry as a major waste discharge cannot be ignored. According to statistics, the pollution caused by desizing in printing and dyeing wastewater accounts for a considerable proportion, accounting for about 50% of textile wet processing and finishing wastewater. A large number of pollutants in desizing wastewater come from the size used in the sizing process. At present, most of the pulp used in textile mills is a mixed pulp composed of natural pulp and chemical pulp. In chemical pulp, PVA has a long biodegradation cycle, which has brought serious environmental problems. The PVA used as a sizing ...
