Embodiment 1

[0024] A kind of production method of fine denier polyester low stretch yarn, comprises the following steps:

[0025] S1: Set the raw silk material on the wire frame, and then introduce the raw material into the first silk feeding roller;

[0026] S2: The raw silk material is introduced into the first heating box through the first silk feeding roller, and the temperature in the first heating box is raised to 158°C before the raw silk material enters the first heating box, and the raw silk material passes through the first heating box. After heating the box, cool it through the cooling plate until the temperature of the raw silk material drops to 95°C, and then cool it naturally to 85°C;

[0027] S3: The raw silk material naturally cooled to 85°C is introduced into the false twister, and then the raw silk material heated for the first time is introduced into the second heating box through the second feeding roller, and the temperature in the second heating box is Raise to 90°C...

Embodiment 2

[0030] A kind of production method of fine denier polyester low stretch yarn, comprises the following steps:

[0031] S1: Set the raw silk material on the wire frame, and then introduce the raw material into the first wire feeding roller; The tube introduces the strand material to the first feed roller.

[0032] S2: The raw silk material is introduced into the first heating box through the first silk feeding roller, and the temperature in the first heating box is raised to 158-168°C before the raw silk material enters the first heating box. After passing through the first heating box, it is cooled by the cooling plate until the temperature of the raw silk material drops to 95-98°C, and then naturally cooled to 85-90°C;

[0033] S3: The raw silk material naturally cooled to 85-90°C is introduced into the false twister, and then the raw silk material heated for the first time is introduced into the second heating box through the second feeding roller, and the second heating box...

Abstract

The invention discloses a production method of fine denier polyester low stretch yarn. The production method comprises the following steps: arranging a raw yarn material on a yarn frame, and introducing the raw material into a first yarn feeding roller; guiding the raw yarn material into a first heating box body through the first yarn feeding roller, cooling the raw yarn material through a cooling plate after passing through the first heating box body, guiding the raw yarn material into a false twister, and then guiding the raw yarn material which is heated for the first time into a second heating box body through a second yarn feeding roller, conveying the raw yarn material passing through the second heating box body to an oiling unit through a third yarn feeding roller for oiling, and then winding the raw yarn material of which oiling is completed. The process is simple, and the quality of the fine denier polyester low stretch yarn manufactured according to the steps is effectively improved.

Description

technical field [0001] The present invention relates to a kind of fine denier polyester low elastic yarn, in particular to a production method of fine denier polyester low elastic yarn. Background technique [0002] Polyester low stretch yarn is a type of textured yarn of polyester chemical fiber. It is made of polyester chip as raw material, high-speed spinning polyester pre-oriented yarn, and then processed by drafting and false twisting. However, when producing fine-denier polyester low-stretch yarns, the quality of the manufactured fine-denier polyester low-stretch yarns is not good due to immature technology, which affects the use effect. [0003] Therefore, those skilled in the art are committed to providing a method for producing fine-denier polyester low-elastic yarns that can effectively solve the above-mentioned technical problems. Contents of the invention [0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by th...
