Embodiment 1）

[0021] The cationic dyeable polyester / polyester / nylon / spandex fabric dyeing method of the present embodiment has the following steps:

[0022] ①Immerse the fabric in the first dyeing solution, add glacial acetic acid to adjust the pH of the first dyeing solution to 5.0, then simultaneously refine, dye polyester fibers and dye cationic dyeable polyester fibers at a temperature of 130°C for 30 minutes, and then cool down to Drain below 60°C.

[0023] The first dyeing solution is an aqueous solution containing 2.0g refining emulsifier, 1.0g high-temperature disperse leveling agent, 5.0g sodium sulfate, 0.9g precipitation preventer, 0.08g disperse dye and 0.91g cationic dye per liter; and the disperse dye The total weight of the fabric is 0.08% of the weight of the fabric, and the total weight of the cationic dye is 0.91% of the fabric weight.

[0024] Among them, the refined emulsifier used is SEM-35N refined emulsifier produced by Shanghai Shinshou Chemical Co., Ltd., and its m...

Embodiment 2～ Embodiment 4）

[0034] The dyeing method of each embodiment is basically the same as that of Example 1, and the differences are shown in Table 1.

[0035] Table 1

[0036]

[0037] The fabrics dyed in each example have no blemishes such as colored flowers and stains, and the color fastness to washing (refer to GB / T3921-2008) and color fastness to rubbing (refer to GB / T3920-2008) both reach grade 4-5.

Abstract

The invention discloses a dyeing method for a cationic dyeable terylene-terylene-polyamide-spandex fabric. The dyeing method comprises the following steps: (1) soaking the fabric in first dye liquor containing a refining emulsifier, a disperse dyestuff and a cationic dye, adding acid to adjust a pH value to 4.0 to 5.5 and then carrying out treatment at a temperature of 120 to 135 DEG C for 20 to 60 min; (2) subjecting the fabric treated in the step (1) to hot water washing, reduction cleaning and acid neutralization successively; (3) soaking the fabric treated in the step (2) in second dye liquor containing an acidic dye, adding acid to adjust a pH value to 4.0 to 7.0 and then carrying out treatment at a temperature of 90 to 105 DEG C for 20 to 60 min; and (4) subjecting the fabric treated in the step (3) to room-temperature washing, discharging liquid and then carrying out acidic dye fixation. The dyeing method provided by the invention enables good dyeing fastness and quality to be obtained, shortens dyeing time and reduces water consumption, thereby greatly lowering energy consumption.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a cationic dyeable polyester / polyester / nylon / spandex fabric dyeing method. Background technique [0002] With the increasing abundance of textile fiber materials, more and more synthetic fibers have been developed, and a variety of synthetic fibers can be blended and interwoven to complement each other in performance. They not only have warm and comfortable wearing properties, but also have different dyeing properties. The fabric has multiple colors, but this puts forward higher and higher requirements for the dyeing and finishing process. [0003] Ordinary polyester fiber (hereinafter referred to as polyester fiber) has the advantages of high strength and not easy to deform, but has the disadvantages of poor air permeability and poor hygroscopicity. Nylon fiber has the advantages of excellent wear resistance and good hygroscopicity, but has disad...
