Embodiment 1

[0029] The pure cotton woven bleached fabric is selected as the pre-dyed fabric, which is subjected to desizing, scouring, and bleaching treatment to remove a large amount of oil, cotton hull and other impurities, and then it is subjected to depilatory enzyme mercerizing treatment. Dye colorant, cationic modifier, leveling agent, dispersant, alkaline reagent, wet rubbing fastness improver PG and water are mixed together to form a dye solution. The mass concentration of each component is:

[0030] Dye toner: 30g / L; cationic modifier: 25g / L; levelling agent: 3g / L; dispersant: 3g / L; alkaline reagent: 5g / L; wet rubbing fastness improver PG: 10g / L. The dyes used are reactive dyes, the cationic modifiers are glycidyl triethyl ammonium chloride and glycidyl trimethyl ammonium chloride, the leveling agent is flat plus O, and the alkaline reagent is Sodium carbonate.

[0033] The pure cotton woven bleached fabric is selected as the pre-dyed fabric, which is subjected to desizing, scouring, and bleaching treatment to remove a large amount of oil, cotton hull and other impurities, and then it is subjected to depilatory enzyme mercerizing treatment. Dye colorant, cationic modifier, leveling agent, dispersant, wet rubbing fastness improver PG and water are mixed together to form a dye solution. The mass concentration of each component is:

[0034] Dye toner: 10g / L; cationic modifier: 12g / L; levelling agent: 1g / L; dispersant: 1g / L; wet rubbing fastness improver PG: 6g / L. The dye color agent used is a reactive dye color agent, the cationic modifier is a chlorotriazine type quaternary ammonium compound, and the leveling agent is octylphenol polyoxyethylene ether and phenethylphenol polyoxyethylene ether.

[0035] Then immerse the treated pure cotton woven bleached cloth in the prepared dyeing liquor to control the bath ratio to 1:5, keep the initial dye...

Embodiment 3

[0037] The pure cotton woven bleached fabric is selected as the pre-dyed fabric, which is subjected to desizing, scouring, and bleaching treatment to remove a large amount of oil, cotton hull and other impurities, and then it is subjected to depilatory enzyme mercerizing treatment. Dye colorants, cationic modifiers, levelling agents, dispersants, alkaline reagents, and wet rubbing fastness improver HT-TMS are mixed with water to form a dye solution. The mass concentration of each component is:

Abstract

The invention provides a method for dyeing fabric by using a dye, belonging to the technical field of textile printing and dyeing and aiming to the solve the problems of complex process, low dyeing rate, poor dyeing uniformity and poor color fastness and hand feel of dyed fabric of the existing method for dyeing the fabric by using the dye. The method comprises the following steps of: desizing the fabric, scouring, bleaching and mercerizing; adding the dye, a cationic modifier, a leveling agent, a dispersant, an alkaline reagent and a wet rubbing fastness enhancer to water, and mixing uniformly to prepare a dyeing solution; soaking the fabric into the dyeing solution, and controlling temperature and liquor ratio to dye; steaming the dyed fabric for colour fixation, washing by water and drying to finish dyeing the fabric by using the dye. The method for dyeing the fabric by using the dye is simple, ensures the high dyeing rate and the uniform dyeing, and ensures that the dyed fabric has good washing fastness and rubbing fastness and a soft feel.

Description

Technical field [0001] The invention relates to a method for dyeing fabrics, more specifically, to a method for dyeing fabrics with dyes, belonging to the technical field of textile printing and dyeing. Background technique [0002] Fabrics refer to textiles made of natural fibers or synthetic fibers. According to different processing methods, they can be divided into woven fabrics, knitted fabrics and non-woven fabrics. They are commonly used raw materials for making clothes, curtains and other daily necessities. Dyes are substances that can color fibers and other materials, mainly natural dyes and synthetic dyes. Dyeing with dyes can make the fabric show various colors that people need, making it more beautiful. [0003] The existing fabric dyeing methods mainly include: pretreatment, spin-drying, dyeing, spin-drying, post-treatment, and drying. Existing fabric dyeing methods all have problems such as complex process, low dye uptake, light color, poor color fastness, and hard h...
