Abstract

The present invention relates to a production process of a chinlon 66 BCF chopped fiber. The chinlon 66 BCF chopped fiber is prepared from raw materials containing chinlon 66 chips, an organic aromatic compound, an antioxidant, a metal salt catalyst and a dispersant by a process route comprising spinning, thermal stretch, hot air jet texturing, air cooling, cutting, fiber transmission and packaging. The prepared BCF chopped fiber has fresh and long-lasting fragrance and good stability, and is the best material for production of carpet.

Description

technical field [0001] The invention belongs to the field of spinning materials, in particular to a production process for producing nylon 66 BCF short fibers 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-spun...
