Embodiment 1

[0014] The components of a short-process low-temperature dyeing auxiliary agent of the present invention are as follows in weight percentage:

[0015]

[0016] The preparation method of this dyeing auxiliary: first add the pure water of the entire formula into the emulsification disperser equipped with a stainless steel stirrer, and then start the equipment to adjust the components according to the maleic acid acrylic copolymer and ethylenediamine di-hydroxyl Sodium phenyl large acetate, sodium ethylene diamine tetramethylene phosphonate, hydantoin, alkyl polyglycoside, glycol phenyl ether, sodium aminoacetate, tristyryl phenol polyoxyethylene ether sulfonate, The secondary alcohol polyoxyethylene ether, benzyl benzoate, and purified water are added sequentially. After all the components are added, the emulsification and dispersion are continued for 0.5-2 hours, and the stirring is stopped after the solution becomes transparent and light brown, and the processing is completed.

Embodiment 2

[0018] The components of a short-process low-temperature dyeing auxiliary agent of the present invention are as follows in weight percentage:

[0019]

[0020] The preparation method of this dyeing auxiliary is the same as in Example 1.

[0021] Taking polyester knitted fabric as an example, the polyester knitted grey fabric is dyed directly into the vat without pre-treatment and degreasing. First, add 1.5-3g / l of the short-flow low-temperature dyeing auxiliary in Example 1 or Example 2 of the present invention, and then Add disperse dye to control the heating rate at 0.6-1°C / min from 60°C, directly increase the temperature to 120-125°C and keep it for 20-50 minutes, and then reduce the temperature to 75°C at a cooling rate of 1-2°C / min Drain the liquid and wash it with water. After dyeing, the medium and light colors need to be washed 1-2 times, and the dark colors need to be washed with hot water above 80℃, and then washed with cold water to get out of the tank, that is, the same...

Embodiment 3

[0025] The components of a short-process low-temperature dyeing auxiliary agent of the present invention are as follows in weight percentage:

[0026]

[0027] The preparation method of this dyeing auxiliary: first add the pure water of the entire formula into the emulsification disperser equipped with a stainless steel stirrer, and then start the equipment to adjust the components according to the maleic acid acrylic copolymer and ethylenediamine di-hydroxyl Sodium phenyl large acetate, sodium ethylene diamine tetramethylene phosphonate, hydantoin, alkyl polyglycoside, glycol phenyl ether, sodium aminoacetate, tristyryl phenol polyoxyethylene ether sulfonate, The benzyl benzoate and purified water components are added sequentially, and the emulsification and dispersion are continued for 0.5-2 hours after all the components are added, and the stirring is stopped after the solution becomes transparent and light brown, and the processing is completed.

Abstract

The invention relates to the field of dyeing, in particular to a short-process low-temperature dyeing aid and a preparation method thereof. The short-process low-temperature dyeing aid is characterized by mainly comprising the following components in percentage by weight: maleic acid acrylic copolymer, sodium ethylene diamine di-orthohydroxyphenyl aceticacid (EDDHA), ethylene diamine tetra sodium, hydantoin, alkyl polysaccharide, ethylene glycol phenylate, sodium glycinate, tristyrylphenol ethoxylates sulfonate, secondary alcohol polyoxyethylene ether, benzyl benzoate and the like. Compared with the prior art, the aid and the method have the advantages that the conventional pretreatment and dyeing processing mode of polyester and blended (yarns) fabrics is thoroughly changed, namely pretreatment processes of the yarns and the fabrics which comprise a yarn and knitwear oil removing process, a woven fabric desizing process, a slight decrement process, a polyester / cotton fabric bleaching treatment process and other processes are combined with a dyeing process to form a one bath treatment process; and the dyeing temperature of one bath dyeing is reduced, reduction clearing processes of most of dyed fabrics are eliminated, water is saved by more than 60 percent, and electricity is saved by more than 30 percent.

Description

Technical field [0001] The invention relates to the field of printing and dyeing of polyester blended yarns and fabrics such as pure polyester, polyester cotton, polyester viscose, polyester spandex, polyester-nylon composite superfine fibers, PTT, PBT and other blended yarns and fabrics, and particularly relates to a short process low temperature Dyeing auxiliary and preparation method thereof. Background technique [0002] Traditional knitted and woven polyester and blended fabrics need to undergo high temperature pretreatment before dyeing to remove textile oil stains, stains, sizing, etc. After pretreatment, they can be dyed by high temperature and high pressure dyeing machine after washing and neutralization. In the high-temperature and high-pressure dyeing machine, high temperature dyeing at 130°C is used. After the dyeing, the medium and dark fabrics need to undergo a reduction cleaning process to remove floating colors and improve washing fastness. The traditional pre-tr...
