Embodiment 1

[0037] First, pre-treat the nylon and spandex blended fabrics provided by Shanghai Jingxuan Garment Co., Ltd., using two-dip and two-rolling. The liquid components are: soda ash 3g / L, hydrosulfite 0.5g / L, JFC 2g / L. Take out and wash with water, soap powder 2g / L, bake at 130°C for 3min, expand and set.

[0038] Next, configure the dye solution: Weak acid brilliant blue RAW 2% o.w.f, leveling agent β-cyclodextrin 3g / L, acetic acid 3g / L, pH adjusted to 5-6, liquor ratio 1:10, feed at room temperature, at 2°C Raise the temperature to 100°C / min, keep it warm for 60min, cool down to 60°C, add disperse blue 2BLN 2% / o.w.f, dispersant NNO 3g / L, ammonium sulfate 3g / L, adjust the pH to 6-7, and use 2 °C / min to 100 °C and keep it warm for 30 min, then cool down to 50 °C at 2 °C / min, take it out, and wash it with water.

[0039] Final color fixation: place the washed fabric in the solution of anionic color-fixing agent DM-2539D (the mass fraction of anionic color-fixing agent DM-2539D is...

Embodiment 2

[0043] According to Example 1, the color was fixed only once, the color fixing temperature was 80° C., and the color was fixed for 30 minutes. The rest were the same as in Example 1, and the dyed nylon and spandex blended fabric was obtained, and the performance was tested (results are shown in Table 2).

[0044] Table 2

[0045]

Embodiment 3

[0047] According to embodiment 1, change disperse dye into disperse blue SE-2R, all the other are identical with embodiment 1, obtain the nylon and spandex blended fabric after dyeing, test performance (results are shown in Table 3).

Abstract

The invention relates to a dyeing method of a nylon / spandex blended fabric. The method comprises the following steps: pretreating the nylon / spandex blended fabric; then carrying out dyeing in the samebath, adding an acid dye, a leveling agent and acetic acid in the dyeing process, adjusting the pH value, carrying out heating, heat preservation and dyeing, adding a disperse dye, a dispersing agentand ammonium sulfate after cooling, adjusting the pH value, and carrying out heating, heat preservation, dyeing, cooling and water washing; and carrying out color fixation. According to the method, an acid dye and a disperse dye are used for one-bath two-step dyeing, the process is simple, and large-scale production can be realized by adopting conventional dyeing equipment.

Description

technical field [0001] The invention belongs to the field of fabric dyeing methods, in particular to a dyeing method of nylon / spandex blended fabrics. Background technique [0002] Nylon has excellent strength, wear resistance and soft feel. It is the best material for down jackets, mountaineering clothes, fishing nets and other finished products. It is often blended or interwoven with other fibers. Its characteristics are as follows: 1. Strong and wear-resistant, nylon fabric is a fabric The one with the best wear resistance, much higher than other fiber fabrics; 2. Nylon fabric is lighter and comfortable to wear; 3. Elasticity and recovery, chemical stability and hygroscopicity are better. [0003] Spandex is a polyurethane fiber. Because of its excellent elasticity, it is also called elastic fiber and has been widely used in clothing fabrics. The main characteristics of spandex fabrics are: 1. Very high elasticity. General products do not use 100% polyurethane, but mostl...
