Abstract

The invention relates to a nylon-66 FDY (Fully Drawn Yarn) filament with anti-static and anti-bacterial functions. The nylon-66 FDY filament is prepared according to a method in which high-speed spinning equipment is adopted, and nylon-66 slices and additives are taken as raw materials. The method comprises the following steps: step 1, carrying out trickling, blowing laterally and oiling with a screw extruder, a pre-filter, a static mixer, a metering pump and a spinning component; and step 2, rolling with a channel, a first godet, a second godet and a third godet, so as to obtain the anti-static and anti-bacterial FDY filament. The FDY filament is high in stability and can meet different requirements of follow-up weaving, trimming and processing.

Description

technical field [0001] The invention belongs to the field of spinning materials, in particular to a nylon 66 FDY filament produced 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 general term for a clas...
