Flame-retardant anti-molten-drop antistatic core-spun yarn and preparation method thereof

Abstract

The invention discloses flame-retardant anti-molten-drop antistatic core-spun yarn and a preparation method thereof. The preparation method of the flame-retardant anti-molten-drop antistatic core-spunyarn comprises the following steps that aramid fibers, flame-retardant viscose fibers and antistatic fibers are mixed and then subjected to combing, drawing and roving in sequence, and the mixture and mixed nylon filaments are subjected to core spun yarn spinning; spooling is carried out, and the core-spun yarn is obtained, wherein the nylon filaments are a mixture obtained through drawing and mixing of flame-retardant nylon filaments and non-flame-retardant nylon filaments. According to the method, the aramid fibers, the flame-retardant viscose fibers, the flame-retardant nylon filaments, the high-strength non-flame-retardant nylon filaments and conductive fibers serve as main components, and a flame-retardant anti-molten-drop fabric is prepared through blending spinning and weaving technologies. The fabric has the advantages of being retardant to flame, resistant to molten drops, high in strength, antistatic, easy to dye, low in cost, simple in process, good in yarn quality and thelike, can be used for meeting requirements in the aspect of special operations and can also meet requirements in the aspects of uniforms and the like.

Description

Technical field [0001] The invention relates to a flame-retardant anti-melt dripping anti-static core-spun yarn and a preparation method thereof, belonging to the textile field. Background technique [0002] In flame-retardant clothing, aramid fiber is usually used as the main material. Aramid fiber is a high-performance fiber with mature technology. Its chemical name is polymetaphenylene isophthalamide (commonly known as aramid 1313) and polypara Phthaloyl p-phenylenediamine (commonly known as Aramid 1414), both of these fibers have good high temperature resistance and flame retardancy, but the glass transition temperature of aramid fiber is high, dyeing is difficult, and water absorption is poor. Therefore, it is difficult for aramid fabrics to have high-quality color, camouflage printing, and cannot meet the camouflage needs of the army; the problem of static electricity is also more prominent, and it cannot be used in gunpowder processing plants, flammable powder processing p...

AI Technical Summary

Problems solved by technology

[0002] In flame-retardant clothing, aramid fiber is usually used as the main material. Aramid fiber is a high-performance fiber with a very mature process at present. Phthalamide (commonly known as aramid 1414), these two fibers have good high temperature resistance and flame retardancy, but the glass transition temperature of aramid fiber is high, dyeing is difficult, and water absorption is also poor Therefore, it is difficult for aramid fabrics to have high-quality color and camouflage printing, which cannot meet the camouflage requirements of the army; the problem of static electricity is also relatively prominent, and it cannot be used in gunpowder processing plants, flammable powder processing plants, etc. that have high anti-static requirements. occasion use

[0003] Aramid fibers are usually used in combat fabrics. The proportion of aramid fibers in the previous generations of combat fabrics of the US military accounted for more than 50%. Due to the difficulty of dyeing aramid fibers, the camouflage printing of the entire combat fabric is difficult, low in strength, and poor in comfort. question

The latest generation of flame-retardant combat fabrics for the U.S. military is made of aramid 1414 / flame-retardant viscose / high-strength nylon 66 (25:65; 10) blended with three fibers. Appropriate wear resistance and comfort; but there are still problems such as poor durability, low strength and high price, and 25% aramid 1414 fiber makes the fabric must be printed with a part of paint, resulting in poor hand feeling still exists
