Embodiment 1）

[0021] The polyester / nylon / cation dyeable polyester / 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 4.5, then simultaneously refine and dye polyester fibers at 130°C for 30 minutes, then cool down to below 60°C to drain the liquid.

[0023] The first dyeing solution is an aqueous solution containing 2.0 g of refined emulsifier, 1.0 g of high-temperature disperse leveling agent and 0.08 g of disperse dye per liter; and the total weight of disperse dye is 0.08% 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 main component is polyoxyethylene nonylphenol ether; the high-temperature disperse leveling agent is produced by Jiangsu Shouxin Chemical Co., Ltd. RDT-27N high temperature disperse leveling agent, its ma...

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 dacron / chinlon / cation dyeable dacron / spandex fabric dyeing method. The dacron / chinlon / cation dyeable dacron / spandex fabric dyeing method comprises the following steps: (1) soaking a fabric into a first dyeing solution containing a refined emulsifier and disperse dyestuffs; adding acid for adjusting the pH to be 4.0 to 5.0; then treating at the temperature of 120 DEG C to 135 DEG C for 20min to 60min; (2) carrying out hot water washing, reduction washing and acid neutralization on the fabric treated by the step (1) in sequence; (3) soaking the fabric treated by the step (2) into a second dyeing solution containing cationic dyestuffs and acidic dyestuffs and adding acid for adjusting the pH to be 4.0 to 6.5; then treating at the temperature of 110 DEG C to 120 DEG C for 30min to 60min; (4) carrying out room-temperature water washing on the fabric treated by the step (3) and carrying out acidic fixation after discharging liquid. The dyeing method disclosed by the invention has relatively good dyeing fastness and quality, the dyeing time is shortened, and the water consumption is reduced, so that energy consumption is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a polyester / nylon / cation dyeable polyester / 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 disadva...
