Abstract

This invention discloses a terylene core-spun thread twisted by two or many terylene core-spun yarns composed of terylene long silk wrapped by terylene short fibers, the process method is as follow: 1) the processed long silks and the short fibers after middle and rear roller drawing are fed into a front roller. 2) the short fibers wrap the long silks in the front roller to become the terylene core-spun yarn to be output from the roller clamp, 3) two or many terylene core-sun yarns are twisted to terylene core-spun threads. The long silk tension is stabilized and controlled by godet hook and a tension disk then to be fed into the front roller after positioning by the carrier rod and the locationing guide wheel.

Description

A kind of terylene covered line and preparation method thereof

Technical field

The present invention relates to a kind of sewing thread that is applied on the Sewing machines, particularly a kind of high speed sewing thread and preparation method thereof.

Background technology

Update along with Sewing machines, its machine speed is also more and more faster, add popularizing of high-grade fabric, the high speed sewing thread that clothing is used often requires powerful high, the powerful coefficient of variation is few, twist height, the yarn defect is few, seamability is good, the sewing thread of now general on the market terylene short fiber spinning can not satisfy user's needs, it mainly is to adopt the mode of hollow ingot unwinding to spin, its shortcoming is: the tension force of unwinding can increase gradually along with dwindling of long filament tube unwinding diameter, in addition during the long filament feeding roller, traverse moves along with moving of short fiber feeding traverse, thereby the generation peeled yarn, in order to satisfy the needs in market, a kind of stable more and twist high speed sewing thread is more uniformly brought into schedule.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of stable more and uniform more terylene covered line of the twist and preparation method thereof.

The technical solution adopted for the present invention to solve the technical problems is: a kind of terylene covered line is to be formed by two or many terylene covered yarn twisteds, and described every terylene covered yarn all is made up of polyester filament outer wrapping terylene short fiber.

A kind of preparation method of terylene covered line is:

(1): treated polyester filament and treated terylene short fiber are fed from front roller;

(2): terylene short fiber is wrapped in front roller and becomes terylene covered yarn outside the polyester filament and export from roller nip;

(3): two or many terylene covered yarns are become terylene covered line behind the twisting machine twisted.

The described polyester filament processing procedure of step (1) is: thereby earlier through traveller and tension pulley control and stable thread-tension; Feed from front roller behind the location by lever jack and location guide wheel again.

The processing procedure of the described terylene short fiber of step (1) is: during terylene short fiber is passed through, the rear roller drawing-off.

The invention has the beneficial effects as follows: the production operation process of this product is simple, the output height, and cost is low; The product of producing not only outward appearance is bright and clean, and the yarn defect is few, and seamability is good, is difficult for balling-up, compare with the ordinary polyester line have powerful height, the powerful coefficient of variation is few, the characteristics that the twist is high, thus can be widely used in the clothing sewing.。

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is a process chart of the present invention.

The specific embodiment

With reference to Fig. 1, a kind of terylene covered line is to be formed by two or many terylene covered yarn twisteds, and described every terylene covered yarn all is made up of polyester filament outer wrapping terylene short fiber.

The concrete steps of producing terylene covered line in the present embodiment are as follows: 1: the terylene short fiber in treated polyester filament and the process, after the rear roller drawing-off is fed from front roller; Described polyester filament processing procedure is: thereby earlier through traveller and tension pulley control and stable thread-tension; Because control well polyester filament tension force size and stable be the important assurance of spinning high-quality bag yarn, so traveller and tension pulley can require make any adjusting according to reality; Feed from front roller behind the location by lever jack and location guide wheel again; Only guarantee that polyester filament is in the center of terylene short fiber all the time in spinning process, could guarantee the effective of product, can not produce ill effects such as peeled yarn, dew heart yarn, locate guide wheel in addition and can follow the feeding of polyester filament and rotation flexibly, thereby can not damage and bump colored polyester filament; 2: terylene short fiber is wrapped in front roller and becomes terylene covered yarn outside the polyester filament and export from roller nip; Terylene covered yarn mainly is that polyester filament is limited on the axis of resultant yarn, and from the cross section of resultant yarn, core is a polyester filament, is terylene short fiber on every side, and both boundaries clearly; 3: two or many terylene covered yarns are become terylene covered line behind the twisting machine twisted according to actual processing request.

The production operation process of this product is simple, the output height, and cost is low; The product of producing Product not only outward appearance are bright and clean, and the yarn defect is few, and seamability is good, is difficult for balling-up, with ordinary polyester Line compare have powerful height, the powerful coefficient of variation is few, the characteristics that the twist is high, thus can be wide General being applied in the clothing sewing.

Claims (2)

1. terylene covered line is characterized in that being formed by two or many terylene covered yarn twisteds, and described every terylene covered yarn all is made up of polyester filament outer wrapping terylene short fiber.

2. the preparation method of a kind of terylene covered line according to claim 1 is:

(1): treated polyester filament and treated terylene short fiber are fed from front roller;

(2): terylene short fiber is wrapped in front roller and becomes terylene covered yarn outside the polyester filament and export from roller nip;

(3): two or many terylene covered yarns are become terylene covered line behind the twisting machine twisted.

The described polyester filament processing procedure of step (1) is: thereby earlier through traveller and tension pulley control and stable thread-tension; Feed from front roller behind the location by lever jack and location guide wheel again.

The processing procedure of the described terylene short fiber of step (1) is: during terylene short fiber is passed through, the rear roller drawing-off.
