Problems solved by technology

[0003] At present, a large amount of alkali agents and scouring agents are used in the dyeing and finishing process of cotton knitted fabrics. Although the scouring effect required for dyeing and finishing can be obtained, it will cause irreversible damage to cotton fibers and make cotton knitted fabrics feel poor. ; At the same time, there are many dyeing and finishing processes at present, and each step needs to consume a large amount of water resources and heat energy, and the cost of dyeing and finishing is too high

Embodiment 1

[0051] An energy-saving dyeing and finishing process, comprising the following steps:

[0052] step one:

[0053] Configure a bath including the following components:

[0054] Anti-wrinkle agent: 1-2g / L

[0055] Degreaser: 1-2g / L

[0056] Leveling agent: 0.1-0.5 g / L

[0057] Yuanming powder: 2g / L

[0058] Glacial acetic acid (97%): 0.3g / L

[0059] Disperse dyes: 1 g / L

[0060] Anti-precipitation agent: 2g / L

[0061] Ordinary cationic dyes: 2 g / L

[0062] Glacial acetic acid (97%): 0.2g / L

[0063] Refining solution: 5 g / L;

[0064] Step 2: Putting the cloth into the treatment solution for polishing and dyeing, wherein the mass ratio of the cotton knitted fabric to the treatment solution is 1:10;

[0065] Step 3: Soaping the cotton knitted fabric after the polishing and dyeing treatment, and putting it into the color-fixing solution after soaping for color-fixing treatment; wherein the mass ratio of the cotton knitted fabric to the color-fixing solution is 1:8;

Abstract

The invention discloses an energy-saving dyeing and finishing process. The process includes: performing one bath pot treatment on cotton knitted fabric, and putting the cotton knitted fabric into refining liquid for refining treatment by using pectinase, wherein octadecyl benzyl dimethyl ammonium chloride, dodecyl diphenyl ether sodium disulfonate, triethanolamine and 3-dimethylamino-1, 2-propylene glycol are added into the refining liquid; polishing the cotton knitted fabric, and integrating polishing with dyeing, wherein N-(hydroxyethyl) ethylenediamine trisodium triacetate, diepoxy glycerylether and 3-dimethylamino-1, 2-propylene glycol are added into treatment liquid; performing saponification and color fixation, wherein hydroxyethyl ethylenediamine, dimethylamino propyl methacrylamide and 3-amino-2-cyclohexene-1-ketone; finishing, wherein substances like 3-(2-aminoethylamine) propyl methyl dimethoxysilane are added into finishing liquid. By process optimizing, alkali consumptionis reduced, process flow is shortened, production cost is lowered greatly, and environment friendliness and energy conservation are realized.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an energy-saving dyeing and finishing process. Background technique [0002] Dyeing and finishing refers to the process of chemically treating textile materials (fibers, yarns and fabrics), which is also commonly known as printing and dyeing in modern times; dyeing and finishing together with spinning, weaving or knitting production form the whole process of textile production ; The quality of dyeing and finishing has an important impact on the use value of textiles. [0003] At present, a large amount of alkali agent and scouring agent are used in the dyeing and finishing process of cotton knitted fabrics. Although the scouring effect required for dyeing and finishing can be obtained, it will cause irreversible damage to cotton fibers and make cotton knitted fabrics feel poor. At the same time, there are many dyeing and finishing processes at present, and each step needs to co...
