Production process of clean appearance pure cotton and cotton blended knitted fabric

Abstract

The invention provides a production process of a clean appearance pure cotton and cotton blended knitted fabric. The production process includes the following operation steps of singeing, alkali shrinking, stacking, dyeing and shaping; specifically, the pure cotton and cotton blended knitted fabric is subjected to singeing by a full width singeing machine with double burners on the cloth cover and a single burner at the fabric bottom; the singed cotton and cotton blended knitted fabric is subjected to alkali shrinkage treatment through an alkali shrinking machine and rolled up to a cloth rack; the fabric on the cloth rack is stacked after sealing packaging; after stacking is ended, the fabric is washed and then subjected to conventional dyeing, and dewatering and drying are carried out after dyeing is completed; and after drying is carried out, the fabric is shaped and made soft, and finally the fabric is discharged from the machine in a shaped mode. Through reasonable improvement ofthe process and parameters, the dye absorption capacity of cotton knitted fabrics is effectively improved, the tightness of the fabric is conducive to achieving low shrinkage rate of a finished product, the fabric cover is less in hairiness and shiny, the resilience and stiffness-smooth are significantly improved, the cost performance is high, and the market demands are met.

Description

technical field [0001] The invention relates to the technical field of textile technology, in particular to a production process for a knitted fabric of pure cotton and cotton blended (including interwoven cotton yarn and synthetic fiber) with a smooth appearance. Background technique [0002] Ordinary pure cotton and cotton blended (including cotton yarn and synthetic fiber interwoven) knitted fabrics have excellent moisture absorption properties, soft touch, and comfortable elasticity, which are favored by people. However, the defects of ordinary pure cotton and cotton blended knitted fabrics are also particularly obvious, such as: too large shrinkage, not wide enough, too much hairiness on the cloth surface, easy to wrinkle, and poor appearance after washing. As a result, it is difficult to enter the ranks of high-end fabrics. [0003] At present, pure cotton and cotton blended (including cotton yarn and synthetic fiber interwoven) knitted fabrics are treated by the merc...

Problems solved by technology

However, the defects of ordinary pure cotton and cotton blended knitted fabrics are also particularly obvious, such as: large shrinkage, not wide enough, more hairiness on the cloth surface, easy to wrinkle, and poor appearance after washing, etc.

As a result, it is difficult to rank among the ranks of high-end fabrics

[0003] At present, pure cotton and cotton blended (including cotton yarn and synthetic fiber interweaving) knitted fabrics are treated by mercerizing technology to change the morphological characteristics of cotton fibers, so that the fabrics have
