Embodiment 1

[0032] A kind of dyeing method of cationic modified cellulose fiber fabric, comprises the following steps:

[0033] (1) Fiber modification: The cellulose fiber fabric is modified with two cationic modifiers, a small-molecular quaternary ammonium salt cationic modifier and a high-molecular quaternary ammonium salt cationic modifier. permanent cellulose fiber gray cloth; the small molecule quaternary ammonium salt cationic modifier is an epoxy quaternary ammonium salt compound, and the high molecular quaternary ammonium salt cationic modifier is a cationic polyacrylamide compound;

[0034] (2) Gray cloth pre-setting: needle plate type setting machine is used, the control temperature is 170°C, the pre-setting time is 40s, and the width is required to be 5% larger than the finished product; the condition of the gray cloth after pre-setting: the door width is 210cm, and the weight is 253g / m , the shrinkage rate is 3%;

[0035] (3) Reduction cleaning: Add reduction detergent and gl...

Abstract

The invention relates to a dyeing method of a cationic modified cellulose fiber fabric. The method comprises the following steps of fiber modification, gray fabric pre-setting, reduction clearing, dyeing auxiliary formula design, preparation, dyeing process and fixation aftertreatment, wherein two cationic modifiers of a micromolecule quaternary ammonium salt modifier and a macromolecule quaternary ammonium salt modifier are used for conducting modification treatment on a cellulose fiber fabric, then dyeing is conducted, and dyeing auxiliaries with special components are added for promoting dyeing. The dyeing method of the cationic modified cellulose fiber fabric has the advantages that cationic modified cellulose fibers are adopted for dyeing, and meanwhile the dyeing auxiliaries with the special components are added to increase the exhaustion rate and fixation rate of dye and improve color fastness to washing of dyeing materials.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a method for dyeing cationic modified cellulose fiber fabrics. Background technique [0002] In recent years, the contradictions in the development of my country's textile industry's ecological circular economy have become increasingly prominent, especially the high dependence on water resources and the environmental problems caused by high emissions have seriously restricted the sustainable development of the industry. According to incomplete statistics, the annual water consumption of my country's textile printing and dyeing industry is 1.7 billion tons, and the sewage discharge is as high as 1.6 billion tons. Compared with foreign countries, the water consumption of my country's textile printing and dyeing industry is 2-3 times that of foreign countries, and the energy consumption is 3-5 times that of foreign countries. Because the traditional dyeing method uses water as the m...
