Abstract

The invention relates to the technical field of alkali shrinkage technology of cloth, and discloses an alkali shrinkage technology of all-cotton jersey. The technology comprises the following steps ofS1, pre-treatment, wherein the pre-treatment of the all-cotton jersey is carried out through an open-width washing machine; S2, alkali padding of the all-cotton jersey; S3, afterfinish processing ofthe all-cotton jersey; and S4, drying and sizing of the all-cotton jersey, wherein the sizing of the all-cotton jersey is completed through a setting machine; and the pre-shrinking process is carriedout. The technology has the following advantages and effects that the pre-treatment is carried out through the open-width washing machine to ensure the uniformity of subsequent alkali shrinkage of theall-cotton jersey, the internal structure of cotton fiber of uniformly alkali-shrunk all-cotton jersey is changed, the ability of dyeing cotton fiber on the dye is improved, the coloring is easier, all fastness indicators reach national standards, the dimensional stability is good, the draping feeling is good, the fabric is stiff and smooth and shiny, and is not easy to pill and wrinkle, and theoverall grade is greatly improved.

Description

technical field [0001] The invention relates to the technical field of the alkali shrinkage process of cloth, in particular to an alkali shrinkage process of cotton jersey. Background technique [0002] Cotton jersey is very common in the market, and consumers are willing to buy it. Pure cotton jersey is a single-sided fabric with 100% cotton. Many T-shirts are made of pure cotton jersey, which has better sweat absorption. Cotton jersey is easy to wrinkle, absorbs water well but sticks to the skin easily, causing a "stuffy" feeling. At the same time, after washing the cotton jersey many times, the glossiness is poor, the color is not bright enough, and the cotton jersey is loose and has no crisp feeling; in order to solve this problem, the cotton jersey is usually treated with an alkali shrinkage process. The process of treating cotton knitted fabrics with concentrated caustic soda solution in a relaxed state. The alkali shrinkage of cotton knitted fabrics has two process...
