Problems solved by technology

[0007] The advantage of this process is: the damage to cotton fibers is usually less, and it is more friendly to the environment; the disadvantage is: the pretreatment effect is not as good as the aforementioned traditional process, and most of them are for cotton fabrics and a few for cotton-polyester fabrics, while For cotton-spandex fabrics, because spandex uses a large amount of silicone oil surfactants in the spinning and weaving process, the existing biological enzyme pretreatment methods are even less effective for cotton-spandex fabrics.
[0008] In addition, the vast majority of cotton fabrics need to be drained before dyeing after pretreatment, and it is difficult to achieve one-bath dyeing, that is, there will be color spots on the fabric surface after one-bath dyeing

Embodiment 1）

[0029] The cotton fabric refining one-bath dyeing process of the present embodiment has the following steps:

[0030] ① Immerse the cotton fabric [this example is 95% cotton + 5% spandex interwoven fabric] in the treatment solution, raise the temperature to 55 °C at a speed of 1.5 °C / min, and perform biological enzyme pretreatment for 60 minutes.

[0031] The treatment solution in this example contains 1.0g / L alkaline pectin lyase, 0.35g / L neutral cellulase, 0.1g / L enriched endonuclease, 0.05g / L laccase, 0.02g / L An aqueous solution of surfactant CLD-H, 1.0g / L spandex scouring degreaser ACR, and 0.5g / L penetrant JFC.

[0032] Among them, the surfactant CLD-H comes from Xi'an Chulongda Chemical Co., Ltd., the spandex scouring degreaser ACR comes from Changzhou Xin'anda Company, and the penetrant JFC comes from Shanghai Fengrui Chemical Co., Ltd.

[0033] ②Then add 80g / L Yuanming powder directly to the treatment solution in step ①, raise the temperature to 80°C at a speed of 4°C...

Embodiment 2～ Embodiment 5）

[0038] The cotton fabric refining one-bath dyeing process of each embodiment is basically the same as that of embodiment 1, and the differences are shown in Table 1.

Abstract

The invention discloses a one-bath dyeing process for cotton fabrics, comprising the following steps: immersing cotton fabrics in a treatment solution containing composite biological enzymes, raising the temperature to 50-58 DEG C, and performing biological enzyme pretreatment for 30-60 minutes; and then directly Add Yuanming powder to the treatment solution, raise the temperature to 75-85°C, and treat for 5-10min to inactivate the composite biological enzyme at high temperature; then add the prepared reactive dye to the treatment solution at a constant speed, and the feeding time is 20-40min , after adding and cooling to 60-70 ℃, add soda ash in 2-3 times, each feeding time is 15-30min, add heat preservation dyeing for 40-60min; after dyeing, drain, wash, adjust acid, drain, Soap. The cotton fabric refining one-bath dyeing process of the invention not only has high whiteness and capillary effect, less damage to fibers, no color flowers on the cloth surface, but also better leveling degree.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and particularly relates to a one-bath dyeing process for refining and dyeing cotton fabrics. Background technique [0002] Cotton is a natural cellulose fiber, and its main component is cellulose, but there will be impurities such as pectin, waxy substances, ash, and natural pigments in the growth process. The existence of these impurities will seriously affect the dyeing process. Therefore, it needs to be removed by scouring, bleaching and other pretreatment processes before dyeing. [0003] At present, there are two main pretreatment processes for cotton fabrics: [0004] (1) The traditional pretreatment process, that is, using a large amount of caustic soda, surfactants, hydrogen peroxide and other chemicals for scouring and bleaching. [0005] The advantages of this process are: good pretreatment effect and stable quality; the disadvantages are: the damage to cotton fib...
