Embodiment Construction

[0010] The present invention will be further described below in conjunction with specific embodiment:

[0011] A kind of dyeing process of polyester-cotton blended fabric hemp gray effect, comprises the following steps,

[0012] First, the cotton yarn is cationic treated, and the polyester is made of full-dull polyester; specifically, by adding a modifier such as a quaternary ammonium compound containing a chlorohydrin group, the cationic group is connected to the cotton yarn fiber after dipping and rolling. Thereby improving the dyeing performance of the fiber;

[0013] Next, weave the cationic-treated cotton yarn and polyester into a single-sided jersey, and turn the cylindrical single-sided jersey through the fabric-reversing machine before entering the tank;

[0014] Then, oxygen bleaching, according to the mass percentage, add 1% multifunctional pretreatment agent, 1.5% multifunctional full treatment agent and 2% hydrogen peroxide, heat to 60 ° C for 10 minutes, then add...

Abstract

The invention discloses a dyeing process for a heather grey effect of a polyester-cotton blended fabric. The dyeing process comprises the following steps: firstly cationic treatment is conducted on cotton yarn, and polyester subjected to complete extinction is selected as polyester; then the cotton yarn subjected to cationic treatment and the polyester are woven into single jersey, and the cylindrical single jersey is turned over through a cloth turn-over machine before entering a cylinder; and then oxygen bleaching is conducted, in percentage by mass, 1% of a multifunctional pretreatment agent, 1.5% of a multifunctional total-treatment agent and 2% of hydrogen peroxide are added, heating is conducted to reach 60 DEG C which is maintained for 10 min, and then 0.8% of glacial acetic acid isadded for normal-temperature operation for 10 min. According to the dyeing process for the heather grey effect of the polyester-cotton blended fabric, the duration is shortened, salt and alkali are not added, and the good heather grey effect is formed.

Description

Technical field: [0001] The invention relates to the field of textile printing and dyeing, in particular to a process for dyeing polyester-cotton blended fabrics with hemp effect. Background technique: [0002] In the prior art, polyester-cotton blended fabrics are dyed with a hemp effect, which requires adding salt and alkali, and also requires high-temperature treatment, resulting in high pressure for sewage treatment and high energy consumption. Invention content: [0003] The technical problem to be solved by the present invention is to provide a process for dyeing polyester-cotton blended fabrics with hemp effect with low energy consumption and no need to add salt and alkali. [0004] The technical solution of the present invention is to provide a kind of dyeing process of polyester-cotton blended fabric hemp gray effect, comprising the following steps, [0005] First, the cotton yarn is cationic treated, and the polyester is made of full-dull polyester; [0006] Ne...
