Problems solved by technology

[0002] There are many types of traditional elastic fabrics, and the elastic effect is not ideal. In order to obtain elastic properties, elastic yarns are mainly used to add spandex fibers to assist in processing and producing fabrics.
[0003] In addition to the unsatisfactory stretching effect of traditional fabrics, the raw materials are not renewable, do not meet the concept of "green, environmental protection, energy saving", and the production cost is high

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 --3 described, a kind of preparation method of elastic knitted fabric, comprises the following steps:

[0025] Step A: select polyester yarn as the raw material yarn count;

[0026] Step B: Enlarging the needle pitch and lengthening the coil through the manufacturing equipment, and weaving with the predetermined knitting needle arrangement and triangular arrangement to obtain the blank;

[0027] Step C: using an open-width water washing process to perform heat and humidity treatment to preshrink the blank to obtain elasticity;

[0028] Step D: Carry out pre-shaping at a temperature of 150--170 degrees Celsius;

[0029] Step E: dyeing at a temperature of 120-130 degrees Celsius;

[0030] Step F: Perform resetting at a temperature of 130--150 degrees Celsius to obtain a finished product.

[0031] In step A, the polye...

Abstract

The invention discloses a preparation method of a comfortable and elastic knitted fabric. The method comprises the following steps that A, a polyester yarn is selected as a raw material yarn; B, by means of weaving equipment, weaving is conducted according to the needle gauge being 24 needles and predetermined knitting needle arrangement and triangle arrangement, a coil is prolonged, and a blank is obtained; C, hot-wet treatment is conducted through an open width washing process, and the blank is preshrunk; D, presetting is conducted at 150-170 DEG C; E, dyeing is conducted at 120-130 DEG C; F, re-setting is conducted at 130-150 DEG C to obtain a finished product. Compared with the prior art, the method has the advantages that the boiling shrinkage characteristics of a two-component bio-based PDT polyester raw material yarn are adopted, when the blank is opened, by adjusting yarn coil lengthening, needle gauge amplification, wet-hot pretreatment of former dyeing and finishing to the blank and softening finishing of back-end dyeing and finishing, the fabric is shrunk to obtain elasticity, a traditional process of obtaining the elasticity only by adding spandex is improved, the adopted raw materials are degradable and conform to the environmental protection concept, and the comfortable and elastic properties are more excellent.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for preparing stretch-elastic knitted fabrics. Background technique [0002] There are many types of traditional elastic fabrics, and the elastic effect is not ideal. In order to obtain elastic properties, elastic yarns are mainly used to add spandex fibers to assist in processing and producing fabrics. [0003] In addition to the unsatisfactory stretching effect of traditional fabrics, the raw materials are not renewable, do not meet the concept of "green, environmental protection, energy saving", and the production cost is high. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a method for preparing stretchy knitted fabrics. The present invention uses a two-component bio-based PDT polyester yarn raw material to lengthen the yarn count coil and enlarge the needle distance when the blank is opened. 1. The wet heat pre...
