Abstract

The invention relates to an infrared BCF (bulked continuous filament) chopped fiber for underwear. The infrared BCF chopped fiber for underwear is made of nylon 6 chips and additives through a process route of spinning, hot stretching, hot air jet texturing, air cooling, chopping, fiber conveying and bagging. The prepared infrared BCF chopped fiber for underwear has functions of infrared absorption and radiation.

Description

technical field [0001] The invention belongs to the field of spinning materials, and in particular relates to an infrared BCF short fiber for producing underwear by slicing. Background technique [0002] At present, synthetic fibers generally include polyester (polyester), nylon (polyamide), polypropylene (polypropylene), spandex (polyurethane), acrylic (polyacrylonitrile) and the like. These fibers have different properties and thus different uses. But at present generally take fabric, because its fiber is thicker, feel rough, softness is poor, air permeability is poor, water absorption is poor, easy to pilling. With the improvement of people's living standards, the requirements for textiles are getting higher and higher. [0003] Polyamide fiber is the earliest synthetic fiber variety put into industrial production in the world. It is made of polyamide synthesized by polycondensation reaction of aliphatic dibasic acid and diamine or aliphatic amino acid, and then melt-s...
