Polyester knitwear fabric and method of processing the same

Abstract

The invention relates to a knitted polyester fabric and a processing method thereof. The fabric comprises covering weave and bottom weave, the raw material of the covering weave is polyester superfine denier fiber, and the raw material of the bottom weave is polyester fiber, wherein, the content of the polyester superfine denier fiber is 60-80 percent of the total ingredients, and the content of the polyester fiber is 20-40 percent of the total ingredients. The invention has the advantages that: as the polyester superfine denier fiber is used as the covering weave and the polyester fiber is used as the bottom weave, the polyester superfine denier fiber can effectively control the rate of retraction, after opening fiber, the fabric has soft cotton handfeel and good temperature suction, elasticity and resistance to deformation and excellent warmth retention and air permeability, and is skin-friendly; and the processing method adopts weft knitting weaving which has short process, small raw material loss, and no parking bars on the fabrics compared with the warp knitting weaving.

Description

technical field [0001] The invention belongs to the technical field of knitted textiles, in particular relates to a knitted polyester fabric, and also relates to a processing method of the knitted polyester fabric. Background technique [0002] Fabrics woven by warp knitting machines such as Raschel double needle bed warp knitting machines widely used in the industry have the advantages of compactness, stability and higher output than circular knitting machines; but the elasticity and feel of the fabrics and The preparation work before production is more cumbersome. Compared with the circular knitting machine, it takes a long time and consumes a lot. The stop bar will obviously leave bar marks on the fabric during weaving. Its disadvantages are many defects and high processing cost. Chinese Invention Patent Application Publication No. CN101113547A recommends a supersoft Raschel plush fabric and its production method. The raw materials selected in the technical scheme of this...

Problems solved by technology

Because the raw material is relatively thick, it is picky about the gram weight, which can only meet 240-320g/m 2 Requirements for less than 240g/m 2 The fabric is difficult or even impossible to process, so not only is there a waste of materials, but also it is not enough to meet the market requirements due to the restriction of the weight, the whole process is time-consuming, and the waste of raw materials is large, and the loss is large

Because there are many cases of raw materials in warping, taking the door width of 59-60 inches as an example, the number of raw materials is 600-800 cases of pipes. According to the implementation method, three kinds of raw materials are used in the same fabric, and each raw material is used. If there are 700 cases of pipes, 2100 heads or joints need to be pierced during warping; the production process is complicated; re-shaping shakers and packaging are arranged in the process flow, but the fabric after the shaker tends to shrink to varying degrees, thus Cause width instability and gram weight deviation; although there is such a teaching in the manual, two sets of ground weave bars of a double-needle bed Raschel warp knitting machine can weave a ground weave that is as stable as a woven fabric, but The elasticity of the fabric produced in this way is often better than none, and the softness, hand feeling and close-fitting feeling when wearing are not ideal; the double-needle bed Raschel warp knitting machine needs to be processed with a belt knife, because it is difficult to maintain the same level with the belt knife and the fabric , so there will be a large deviation in the weight of the same door width. In addition, the two pieces of fabric that have been cut with a knife are usually divided into A side and B side, and the fabrics on A and B sides show significant weight deviations.
