Embodiment 1

[0015] A kind of production method of knitted denim has the following process steps:

[0016] a. Warping: use a warping machine for pure cotton ring spinning;

[0017] b. Dyeing: Use a dyeing machine to carry out bundle-like indigo reduction dyeing of the warped pure cotton ring-spun yarn, and add dyeing auxiliary polyvinyl acetate emulsion Perapret PE-2 produced by BASF in Germany to soften the yarn. deal with;

[0018] c. Distributing warp: use the warp dividing machine to divide the dyed yarn;

[0019] d. Tube-making and untwisting: Use tube-making and untwisting machinery to make tubes and untwist to make indigo cheeses with small head-to-tail color difference, strong color fastness, no end breakage, and uniform tension, suitable for knitting denim weaving;

[0020] e. Weaving: Feed the indigo cheese into the knitting weft knitting machine and cut the width after weft knitting;

[0021] f. Finishing with a padder: ① Feed the cloth, feed the woven cloth through the cloth...

Abstract

The present invention relates to fabric producing technology, and is especially process of producing knitted denim. The present invention has softening treatment on the yarn via adding assistant during the indigo reducing dyeing course, and several times of softening treatment and hot settling in the dewisting course and the post-finishing course, so that cheap ring yarn may be used in producing knitted denim for lowering production cost. The produced knitted denim has stable elasticity, high wash ability, high wrinkle resistance, high permeability and soft handing and is ideal fabric for making high grade costume, especially sports wear, etc.

Description

technical field [0001] The invention relates to the technical field of textile manufacturing, in particular to a production method of knitted denim. Background technique [0002] Traditional denim is made of pure cotton ring-spun yarn. It has the characteristics of rough style, stiff fabric, poor air permeability, and white core. It is used to make trousers and jackets, but not underwear. Traditional weft-knitted fabrics are made of air-spun weft-knitted fabrics. They are soft, breathable, comfortable, free of white cores, and highly elastic. They are often used to make underwear. With the development of society and the improvement of people's living standards, fashion, uniqueness and distinctive personality are pursued for clothing, so clothing fabrics are also required to be diverse. In recent years, people have developed a knitted denim fabric with a denim style kneaded in the traditional weft knitted fabric. It has stable elasticity and still has the characteristics of...
