Embodiment 1

[0015] The DTY high elastic yarn is prepared by using the POY-DTY process with polyamide 6 chips and additives as raw materials, 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→corridor→POY winding yarn; among them: melt spinning temperature: 270-278℃; side blowing conditions: wind speed is 0.2-0.5 m / s, wind temperature 25-30 ℃, relative humidity 60-75%; oiling rate 0.70-1.50%; spinning speed 3500-4500 m / min; DTY production process route: yarn guide→feeding roller→first Hot box→cooling plate→false twister→output roller→oiling device→DTY winding wire; wherein, the temperature of the first hot box is 140-175 ℃, the D / Y ratio is 1.2-1.8, and the drafting ratio is 1.20-1.30. Based on the weight of the polyamide 6 slices, the additives include 0.35wt% sodium methacrylate, 0.12wt% lithium bromide, 0.4wt% dibutyltin laurate, 0.20wt% silver-loaded dioxide Silica gel, 1.2...

Abstract

The present invention relates to a process for an antistatic and antibacterial polyamide 6DTY high elastic filament, which is prepared from raw materials comprising polyamide 6 chips and additives by a POY-DTY process on high-speed spinning equipment. The prepared DTY high elastic 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, and in particular relates to a DTY high elastic yarn process for producing polyamide 6 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 ...
