Abstract

The present invention relates to a process for an antistatic and antibacterial polyamide 6FDY filament. The 6FDY filament is prepared from raw materials containing polyamide chips and additives on a high-speed spinning device by a process route comprising a screw extruder, a pre-filter, a static mixer, a metering pump, a spinning assembly, flow, side blowing, oil application, a spinning shaft, a first godet, a second godet, a third godet and winding. The prepared FDY filament has antistatic and antibacterial function, and good stability, and can meet different requirements of post-weaving finishing.

Description

technical field [0001] The invention belongs to the field of spinning materials, in particular to a process for producing polyamide 6 FDY filaments 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. A genera...
