Method of dyeing fabric by using dye

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 fabric dyeing method, in particular to a fabric dye dyeing method, which belongs to the technical field of textile printing and dyeing. Background technique

[0002] Fabric refers to textiles made of natural fibers or synthetic fibers. According to different processing methods, it can be divided into woven fabrics, knitted fabrics and non-woven fabrics. It is a common raw material for making clothes, curtains and other daily necessities. Dyes refer to substances that can color fibers and other materials, mainly including natural dyes and synthetic dyes. Dyeing with dyes can make the fabric present various colors that people need, making it more attractive in appearance.

[0003] Existing fabric dyeing methods mainly include: pre-treatment, drying, dyeing, drying, post-treatment, drying. The existing fabric dyeing methods all have the problems of complex process, low dye uptake, light color yield, poor color fastness, and ha...

Embodiment 1

[0029] Select pure cotton woven bleached fabric as pre-dyed fabric, desizing, scouring and bleaching it to remove a large amount of impurities such as oil agent and cotton shell, and then subjecting it to hair removal enzyme mercerizing treatment. Mix the dye color agent, cationic modifier, leveling agent, dispersant, alkaline reagent, wet rubbing fastness improving agent PG and water together to prepare a dye liquor. The mass concentration of each component is:

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

[0031]Then immerse the treated pure cotton woven bleached cloth in the prepared dye solution to control the b...
