Embodiment 1

[0018] With nylon 6 slices, bamboo charcoal powder microcapsules, antioxidants, metal salt catalysts and dispersants as raw materials, the POY-DTY process is used to prepare the DTY high elastic yarn, wherein in the POY-DTY process, the POY process route is : screw extruder→prefilter→static mixer→metering pump→spinning assembly→spinning→side blowing and oiling→chone→POY winding yarn; among them: melt spinning temperature: 270-278℃; side blowing Conditions: wind speed 0.3-0.5 m / s, wind temperature 20-30 ℃, relative humidity 60-75%; oiling rate 0.70-1.50%; spinning speed 3500-4500 m / min; among them, DTY production process The route is: yarn guide → feeding roller → first hot box → cooling plate → false twister → output roller → oiling device → DTY winding yarn; among them, the temperature of the first hot box is 150-175 ℃, D / The Y ratio is 1.0-2.0, and the draft ratio is 1.20-1.30. The raw material is based on the weight of nylon 6 slices, the consumption of bamboo charcoal po...

Abstract

The invention relates to a nylon 6 DTY (Draw Textured Yarn) fiber spinning method. According to the method, nylon 6 slices, bamboo charcoal powder microcapsules, an anti-oxidant, a metal salt catalyst and a dispersant are adopted as raw materials; and the POY (pre-oriented yarn)-DTY technology is adopted. The DTY high stretch yarn prepared according to the method has a long-lasting faint scent, 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, and in particular relates to a spinning process for producing polyamide 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-spu...
