Embodiment 1

[0014] The composition of a short-process low-temperature dyeing auxiliaries of the present invention is by weight percentage:

[0015]

[0016] The preparation method of this dyeing auxiliary: First add the pure water of the whole formula into the emulsification disperser equipped with a stainless steel agitator, then start the equipment, and mix each component with maleic acid acrylic acid copolymer, ethylenediamine di-ortho-hydroxy Sodium phenyl macroacetate, sodium ethylenediamine tetramethylene phosphonate, hydantoin, alkyl polyglucoside, ethylene glycol phenyl ether, sodium glycine, tristyrylphenol polyoxyethylene ether sulfonate, Secondary alcohol polyoxyethylene ether, benzyl benzoate, and pure water are added sequentially. After adding all the components, continue to emulsify and disperse for 0.5-2 hours. Stop stirring when the solution becomes transparent and light brown, and the processing is completed.

Embodiment 2

[0018] The composition of a short-process low-temperature dyeing auxiliaries of the present invention is by weight percentage:

[0019]

[0020] The preparation method of this dyeing auxiliary is with embodiment 1.

[0021] Taking polyester knitted fabrics as an example, the polyester knitted gray fabric is directly put into the vat for dyeing without pre-treatment and degreasing, and the short-process low-temperature dyeing auxiliary 1.5-3g / l in the embodiment 1 or embodiment 2 of the present invention is first added, and then Add disperse dyes and control the temperature rise rate at 0.6-1°C / min from 60°C, directly raise the temperature to 120-125°C and keep it for 20-50 minutes, then lower the temperature to 75°C at a cooling rate of 1-2°C / min Afterwards, drain and wash with water. After dyeing, the medium and light colors can be washed with water for 1-2 times, and the dark colors need to be washed with hot water above 80°C once, and then washed with cold water to be re...

Embodiment 3

[0025] The composition of a short-process low-temperature dyeing auxiliaries of the present invention is by weight percentage:

[0026]

[0027] The preparation method of this dyeing auxiliary: First add the pure water of the whole formula into the emulsification disperser equipped with a stainless steel agitator, then start the equipment, and mix each component with maleic acid acrylic acid copolymer, ethylenediamine di-ortho-hydroxy Sodium phenyl macroacetate, sodium ethylenediamine tetramethylene phosphonate, hydantoin, alkyl polyglucoside, ethylene glycol phenyl ether, sodium glycine, tristyrylphenol polyoxyethylene ether sulfonate, Benzyl benzoate and pure water components are added sequentially, after adding all the components, continue to emulsify and disperse for 0.5-2 hours, stop stirring when the solution becomes transparent and light brown, and the processing is completed.

[0028] Take the polyester / viscose blended woven fabric as an example, the polyester / visco...

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 printing and dyeing field of pure polyester, polyester cotton, polyester viscose, polyester spandex, polyester nylon composite superfine fiber and other polyester blended yarns and fabrics, PTT, PBT and other blended yarns and fabrics, and particularly relates to a short-process low-temperature Dyeing auxiliary and its preparation method. Background technique [0002] Traditional knitted and woven polyester and blended fabrics need to undergo high-temperature pre-treatment before dyeing to remove textile oil stains, stains, sizing, etc. After pre-treatment, they can be washed and neutralized before they can be dyed by high-temperature and high-pressure dyeing machines. In the high-temperature and high-pressure dyeing machine, the high temperature of 130°C is used for dyeing. After dyeing, the medium-dark fabrics need to undergo reduction cleaning to remove floating colors and improve washing fastness. The traditional pretr...
