Abstract
The present invention discloses an active dye dyeing process of a jean fabric. According to the present invention, a series of processes such as pre-treatment process, pre-shaping, dyeing, color fixation, post-finishing, water washing and air-drying are adopted, a double-active group active dye is adopted to replace the previous indigo blue dyeing solution and the sulfur dye, and the reasonable dyeing process condition is assistedly adopted to carry out the special dyeing process for the jean fabric; and the prepared finished product has advantages of rich color, uniform and stable color, color losing resistance during the water washing process, and the like, and the active dye is used, such that the amount of the discharged printing and dyeing wastewater in the previous dyeing process is substantially reduced so as to easily achieve the ecology environment.
Description
Technical field
The present invention relates to the dyeing of fabric, relate in particular to a kind of reactive dyeing process of jean.
Background technology
Since the eighties in 20th century, denim has been with rapid changepl. never-ending changes and improvements in the development of China, and the center of production of denim has been transferred to the country of the low labor cost in Asia by countries such as the U.S., especially China.Cowboy is also because the features such as it is wear-resisting, endurable, fashion become at present widely popular ready-made clothes materials.But traditional denim fabric generally adopts ciba blue 2b dyestuff or SULPHUR DYES to dye, the fabric color of producing is on the one hand single, can not meet the pursuit of people to fashion, exist on the other hand color unstable, washing process in easily fade, daily washing protected and caused puzzlement, the processing cost of the dyeing waste water that sulfide dyeing produces is in addition too high, and environment is caused to adverse influence.
Therefore, need a kind of new technical scheme to address the above problem.
Summary of the invention
Goal of the invention: in order to solve the existing problem of prior art, the invention provides the discharge of a kind of environmental contaminants less, abundant, the colour stable of dyed color, finished product wash the reactive dyeing process of the jean that is difficult for fading.
Technical scheme: for achieving the above object, the reactive dyeing process of a kind of jean of the present invention, comprises the following steps:
(1) pre-treatment process: jean fabric to be dyeed new production pack is dropped into rinsing machine and once wash, add destarch enzyme OD-355 according to the consumption of 6-9g/L, temperature is that 70-80 ℃, bath raio are 1:20-1:40, and washing time is 10-20min; Wash and carry out intermediate water after the complete 15-20min of banking up and wash, temperature is that 80-85 ℃, bath raio and washing time are with for the first time;
(2) pre-setting: the fabric after washing is carried out to presetting technology at 140-150 ℃;
(3) dyeing: first prepare dye liquor, by the REACTIVE DYES of double-active group, 25% caustic soda, blowing agent, bleeding agent mixing post-foaming, REACTIVE DYES consumption is 40-50g/L, and amount of caustic soda is 15-20mL/L, foaming agent consumption is 10-15g/L, and bleeding agent consumption is 2-4g/L; Fabric is immersed in the dye liquor after foaming, and bath raio is 1:5-1:10, processes after 2-5min with soaping after the washing 5min of 60-70 ℃ for 130-140 ℃, then washes and once carry out afterwards roll compacting technique, and the padding machine speed of a motor vehicle is 50-65m/min, is dried to eighty per cant dry;
(4) fixation: the fabric after drying is reentered into dye vat, and bath raio is 1:15-1:25, adds glacial acetic acid and color-fixing agent, and wherein glacial acetic acid addition is 1-2g/L, and color-fixing agent addition is 1-2g/L, is warming up to 50-60 ℃ of insulation 30min, takes out washing;
(5) postfinishing process: carry out softness sizing and shrunk finish technique, add softener and dressing liquid, both additions are respectively 5-8g/L and 10-12g/L, and bath raio 1:15-1:25 soaks after 10-15min, carries out whole latitude, 110-125 ℃ of hot-air seasoning;
(6) wash and dry: washing, the fabric after washing is positioned over to ventilating and cooling place and dries, temperature is 25-35 ℃.
More preferred, the washing pH of described step (1) controls as 6.0-7.0.
More preferred, the REACTIVE DYES of described double-active group is Type B, EF type.
More preferred, described blowing agent is surfactant-based blowing agent.
More preferred, in described step (3), bake out temperature is 70-80 ℃.
Beneficial effect: the reactive dyeing process of a kind of jean provided by the present invention, by a series of operation of pre-treatment process-pre-setting-dyeing-fixation-arrange afterwards-wash-dry, adopt the REACTIVE DYES of double-active group to replace indigo dye liquor and SULPHUR DYES in the past, and be aided with rational dyeing condition and be applicable to the special dyeing of jean, obtained finished product has rich color, color is uniform and stable, the advantage such as be difficult in water-washing process fading, and the use of REACTIVE DYES, greatly reduce the dyeing waste water amount of discharging in dyeing in the past, be conducive to ecological environment.
