Abstract

The invention relates to a chinlon 66 fiber spinning method. According to the method, high-speed spinning equipment is adopted; and chinlon 66 slices, thiazole aromatic compound, an anti-oxidant, a catalyst, a delusterant and a dispersant 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 a FDY (Fully Drawn Yarn) filament with a long-lasting faint scent and high stability. The FDY filament can meet different requirements of follow-up weaving, trimming and processing.

Description

technical field [0001] The invention belongs to the field of spinning materials, and in particular relates to nylon 66 fiber spinning and a preparation method thereof. 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. ...
