High-strength flame-retardant leather sewing thread

Abstract

The invention mainly relates to the field of textile processing technology, and discloses a high-strength flame-retardant leather sewing thread, which comprises the following raw materials, by weight:33-35 parts of aramid, 21-23 parts of bamboo fiber, 21-23 parts of cotton fiber, 16-18 parts of ceramic fiber, 12-14 parts of polyacrylonitrile-based carbon fiber; the high-strength flame-retardant leather sewing thread has high strength, high tightness and strong stability, and can effectively inhibit combustion with flame retardant grade reaching V-1 level, and can improve the strength and grade of leather products; blending bamboo fiber and cotton fiber into core yarn can improve the strength and anti-bacterial property of sewing thread, inhibit the production of mould, avoid mouldy sewingthread after long-term use, and prolong the service life of leather products. The core yarn is soaked in sodium selenite solution after completion, and the shrinkage ratio of core yarns is reduced toless than 0.5%, and the sewing fastness of leather products is increased and the health care and bacteriostasis function of sewing thread is improved.

Description

technical field [0001] The invention mainly relates to the technical field of textile processing, in particular to a high-strength flame-retardant leather sewing thread. Background technique [0002] With the gradual improvement of people's living standards, more and more leather products are used, such as clothing, gloves, shoes, bags, furniture, decorations and automotive supplies, etc. Leather products generally have a higher frequency of use and cleaning, and The use strength is relatively high, so there are also high requirements for leather sewing threads. Not only high strength and good wear resistance are required, but also strong corrosion resistance and high temperature resistance, especially for furniture and automotive supplies made of leather materials. , once it burns, it will cause great disasters. Therefore, sewing threads with high strength and flame retardancy can not only improve the grade of leather products, but also inhibit burning and reduce the occurr...

Problems solved by technology

[0003] The existing patent document CN 107916479 A discloses a production process of flame-retardant sewing thread, which specifically discloses that aramid 1313 fibers are sprayed with auxiliary agents, and then steamed at 80°C for 24 hours for pretreatment, and then opened and cleaned → Carding → Two draw frames → Spinning the roving into aramid 1313 roving, and further weaving into aramid 1313 sewing thread, the additive formula is: add softener 0.4, antistatic agent 0.6, water 5kg according to 100kg of raw materials Ratio preparation; it uses the flame retardant performance of aramid fiber 1313 itself, but it is soaked in softener and antistatic agent to reduce the yarn breakage rate and yarn defects, but pure aramid fiber 1313 itself is still relatively fluffy, and it is suitable for sewing leather When using the fluffy aramid fiber 1313 for sewing, the leather is thick and the structure is dense, and it is easy to cause needle hole blockage and thread breakage. Frequent thread changes not only reduce the production efficiency of leather products, but also significantly reduce the quality of leather products due to more thread ends. grade, so the market needs a special high-strength flame-retardant sewing thread for leather
