A high-strength flame-retardant anti-melt drop wear-resistant anti-static blended wrapping core-spun yarn and its preparation method

Abstract

The invention discloses a high-strength flame-retardant anti-dripping wear-resistant antistatic blending wrapping core-spun yarn and a preparation method thereof. The preparation method comprises thesteps of mixing an aramid fiber, a flame-retardant viscose fiber and an antistatic fiber, and conducting combing, drawing and roving to obtain rove; for the rove, using a non-flame-resistant nylon filament as a core, controlling a flame-retardant nylon filament to be wound on an outer layer, spinning a spun yarn, and spooling to obtain the blending wrapping core-spun yarn. The yarn adopts the aramid fiber, the flame-retardant viscose fiber, the flame-retardant nylon filament, the high-strength non-flame-resistant nylon filament and a conductive fiber as main components, a flame-retardant anti-dripping fabric is prepared by blending spinning and weaving process, the fabric has the advantages of flame retardant, anti-dripping performance, high strength, easy dyeing, antistatic performance, abrasion resistance, low cost, simple process, excellent yarn quality and the like, and the yarn can be used not only for requirements of special operations but also for requirements of other aspects such as work clothes and the like.

Description

technical field [0001] The invention relates to a high-strength flame-retardant anti-melt drop wear-resistant anti-static blended wrapping core-spun yarn and a preparation method thereof, belonging to the field of textiles. Background technique [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-...

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
