Problems solved by technology

At present, the commonly used color-fixing agents mostly achieve color-fixing through chemical reactions. The performance of different color-fixing agents is quite different, and there is also a specific tendency for the selection of dyes. It is generally difficult for color-fixing agents to take care of such factors as rubbing fastness, Washing fastness, light fastness, perspiration fastness and other indicators, so there are still many defects, which need to be continuously improved through further technical development and improvement

Embodiment 1

[0015] The microwave method provided by the present invention is applied to printing and dyeing color-fixing cloth, and the color is fixed directly through microwave action. The frequency of the microwave is 1900-2200 MHz, and the action time is 30-40 minutes. After the color is fixed, follow-up treatment is carried out.

[0016] Taking the above color fixing methods, compared with no color fixing, the average rubbing fastness of the final printed and dyed fabrics has increased by more than 30%, the average wash fastness has increased by more than 20%, and the average light fastness has increased by more than 12%. Perspiration fastness increased by more than 13% on average. Therefore, it is a very effective way to fix the color of printed and dyed fabrics by means of microwave action. The color fixation is achieved by microwaves, without introducing new substances into the fabric, which can ensure the effect of the fabric after dyeing.

Embodiment 2

[0018] In this example, the microwave frequency is 1600 MHz, and the action time is 30-40 minutes for microwave color fixation. Compared with Example 1, the final color fixation effect and the rubbing fastness of the printed and dyed fabrics are reduced on average. 25% or more, washing fastness decreased by more than 23% on average, light fastness decreased by more than 26% on average, perspiration fastness decreased by more than 18% on average. Therefore, the present invention finally draws through a large number of tests that in the general color fixing process of printing and dyeing, the color fixing effect of the microwave frequency of 1900-2200 MHz is better than that of other frequencies.

Embodiment 3

[0020] In this embodiment, in the dyeing and fixing process of the cloth, a common color fixing agent is used, which can significantly improve the rubbing fastness and light fastness of the cloth. The microwave frequency of cooperating with the color fixing agent for color fixing is 1600-1800MHz, and the action time is 10-20 minutes. In the process of using the color fixing agent to fix the color, microwave action is added. The rubbing fastness of the color agent has been increased by 20%, and the light fastness has been increased by 28%. At the same time, in a large number of color-fixing experiments, microwaves were introduced for synergistic color-fixing. Finally, it was concluded that microwaves can work well with color-fixing agents, which not only shortens the color-fixing time of color-fixing agents, but also enhances the color-fixing properties of color-fixing agents. color effect.

Abstract

The invention discloses a method for treating dye-printing color fixation cloth with microwaves. The method comprises the following step: at a dye-printing color fixation stage of cloth, color fixation is achieved through microwaves, wherein the microwaves have a frequency range of 1900-2200 MHz; the microwave color fixation time can be 30-40 minutes. In addition, synergetic color fixation can beachieved with microwaves while a color fixation agent is used at the dye-printing color fixation stage to perform color fixation, and the color fixation effect can be remarkably improved.

Description

technical field [0001] The invention belongs to the field of printing and dyeing color fixing, and in particular relates to a method for microwave treatment of printing and dyeing color fixing cloth. Background technique [0002] Fabric dyeing is a relatively complicated process. Different quality fabrics have different dyeing processes, such as cotton, polyester cotton, hemp cotton, woolen woolen fabrics, silk products, chemical fiber products, etc. Some can use pad dyeing and jigger dyeing. If you want to use high temperature and high pressure dyeing. Some are dyed only once, while others are painted multiple times. There are also different processes for using different dyes. Taking basic cotton as an example, in addition to controlling the known factors, there are many unknown factors in the dyeing color, such as the stability of the dye at different temperatures, the control of steam, and the pressure of the paddle. Control, etc., all require a specific scope of contro...
