Abstract

The invention discloses a drafting process finishing method for spinning 5tex fibers by using recycled polyester fibers. The drafting process finishing method comprises a drafting device required by a drafting process, and the drafting device comprises an extrusion structure, a drafting structure arranged at one end of the extrusion structure and a cover plate placed between the extrusion structure and the drafting structure; and the extrusion structure comprises a hopper, an extrusion roller rotationally connected to one end of the hopper, a discharging plate welded to the outer wall of one end of the hopper and a bundling structure installed at one end of the hopper. A finishing method for spinning 5tex fibers through recycled polyester fibers comprises the steps that firstly, the recycled polyester fibers are placed in the discharging plate, the recycled polyester fibers are conveyed into the extrusion roller through a worker, and the polyester fibers are extruded and preliminarily shaped through the extrusion roller. Compared with a traditional mode, the phenomenon that polyester fibers are broken and bifurcated in the drafting process is reduced, the damage rate is reduced, repeated utilization is facilitated, and the qualified rate of products is increased.

Description

technical field [0001] The invention relates to the technical field of polyester fibers, in particular to a drafting finishing method for spinning 5tex fibers using recycled polyester fibers. Background technique [0002] Polyester fiber, commonly known as "polyester". It is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol, referred to as PET fiber, which belongs to polymer compounds. Invented in 1941, it is currently the largest variety of synthetic fibers. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery ability. It is durable, anti-wrinkle, non-ironing, and non-sticky; tex=g / L*1000, where g is the weight (grams) of yarn (or silk), and L is the length (meters) of yarn (or silk); [0003] The re-drawing process of the polyester fiber recovered by the traditional method is likely to cause the polyester fibe...
