Embodiment 1）

[0013] The method of dyeing the fabric containing polyester fiber and cotton fiber of the present embodiment has the following steps:

[0014] ① Dyeing polyester fiber: immerse the fabric containing polyester fiber and cotton fiber in the dye vat filled with the first dye solution, and dye the polyester fiber in the fabric at a temperature of 130°C for 30 minutes.

[0015] The fabric used in this example is a single jersey fabric woven with 93% cotton-polyester blended yarn (CVC 60 / 40 30S) and 7% spandex (30D).

[0016] The pH value of the first dyeing liquor is 4.5, which contains 1.02g of disperse dyes, 1.0g of glacial acetic acid, 0.5g of disperse leveling agent, 1.0g of multifunctional dispersant and 1.0g of refining emulsifier per liter an aqueous solution; and the total weight of disperse dyes is 1.221% by weight of the fabric.

[0017] Among them, the disperse dyes are disperse yellow Y-10GN produced by Jinglian Trading Co., Ltd. and disperse blue TU / B-CC produced by S...

Abstract

The invention discloses a method for dyeing a fabric containing polyester fiber and cotton fiber. The method comprises the following steps of: (1) immerging the fabric containing polyester fiber and cotton fiber into a dyeing vat filled with a first dyeing solution so as to dye the polyester fiber in the fabric; (2) after discharging out the first dyeing solution, adding a refining solution to the dyeing vat and refining the fabric; (3) after discharging out the refining solution, adding a second dyeing solution to the dyeing vat so as to dye the cotton fiber in the fabric; (4) first soaping the dyed fabric and then pickling the fabric for fixation. Compared with the traditional process, the method for dyeing the fabric containing polyester fiber and cotton fiber, disclosed by the invention, is used for reducing the washing reducing process after the polyester fiber is dyed so that the use of sodium hydrosulfite is avoided, the dyeing time is reduced, the water usage is reduced, the energy consumption is largely saved and no pollution to the environment is avoided.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and in particular relates to a method for dyeing fabrics containing polyester fibers and cotton fibers. Background technique [0002] The textile printing and dyeing industry has always been an industry with high energy consumption and high pollution. According to statistics, the coal consumption per 10,000 meters of cloth in my country is about 3 tons, the power consumption is 450KW / hour, the water consumption is 300-400 tons, and the energy consumption is 3 to 5 times the international advanced level, the water consumption is 2 to 3 times. With the increasing efforts of the country on environmental protection, especially the elimination of backward production capacity, and the arrival of low-carbon economy, how to develop energy-saving and consumption-reducing processes has become a top priority for printing and dyeing enterprises. [0003] Cotton fiber has a good feel and excellent h...
