Embodiment 1）

[0018] The nylon / cation dyeable polyester / polyester fabric one-bath dyeing method of the present embodiment has the following steps:

[0019] ① Soak the fabric in the pretreatment solution, pretreat it at 95°C for 40 minutes, and then pickle it.

[0020] This pretreatment solution is an aqueous solution containing 2.0 g of refined emulsifier and 1.0 g of sodium carbonate per liter.

[0021] 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.

[0022] The nylon / cation dyeable polyester / polyester fabric used in this embodiment is 35% nylon, 35% cationic dyeable polyester, and 30% polyester interwoven knitted fabric.

[0023] ②Immerse the fabric after the pretreatment in step ① in the dyeing solution, dye at 120°C for 45 minutes, and then cool down to below 60°C to drain the liquid.

[0024] The dyeing solution is an aqueous solution containing 3.0g s...

Embodiment 2～ Embodiment 4）

[0031] The dyeing method of each embodiment is basically the same as that of Example 1, and the differences are shown in Table 1.

[0032] Table 1

[0033]

[0034] 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 method for one-bath dyeing on a nylon / cationic dyeable polyester / polyester fabric, wherein the method comprises the following steps: 1, dipping a fabric in a pretreatment liquid, treating for 20 min-60 min, and then pickling; 2, dipping the fabric obtained after pretreatment in a dyeing liquid containing a polyester whitening agent, a cationic dye and an acidic dye, dyeing for 30 min-60 min at the temperature of 110 DEG C-130 DEG C, then cooling to 60 DEG C or less, and discharging the liquid; and 3, firstly, washing the dyed fabric with water at room temperature, discharging the liquid, and then carrying out acidic color fixation. According to the method, by choosing the suitable polyester whitening agent, cationic dye and acidic dye, one-bath dyeing on the nylon / cationic dyeable polyester / polyester fabric can be achieved, the dyed fabric is free of defects such as dyeing defects, color spots and the like, the washing color fastness and the friction color fastness are both relatively high, the quality is relatively good, moreover, the dyeing process flow is shortened, the damage to fibers is reduced, and thus the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a one-bath dyeing method of nylon / cation dyeable polyester / polyester fabric. 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] Nylon fiber has the advantages of excellent wear resistance and good hygroscopicity, but has disadvantages such as poor air permeability, easy to wrinkle, and easy to generate static electricity. Ordinary polyester fiber (hereinafter referred to as polyester fiber) has the advantages of high strength ...
