Grey Fabric Classroom - Factors Influencing the Brightness of Fluff Cloth Prints

Grey cloth classroom starts, and Xiao Bian together to rise knowledge ~ ~

Today, we talk to you about the factors that affect the velvet prints.

1. The effect of process selection on the vividness of the flower color: The printing process has a great influence on the vividness of the flowers. Therefore, the sample selection process is crucial. At present, the printing process of the flannel cloth is nothing more than the following four: the whole ice process, the ice live process , Full live technology, pull live technology, these four kinds of craft have their own advantages and disadvantages, the process of production should be combined to develop a practical and feasible process.

2. The effect of the pretreatment process on the vividness. Generally there are two kinds of pre-treatment bleaching process for cotton fabrics, namely oxygen bleaching and chlorine bleaching. Chlorine bleaching has a greater influence on the vividness of flower color than oxygen bleaching. Therefore, oxygen bleaching should be used as much as possible.

3. Effect of colorant on vividness:

(1). Ice-dyeing dyes, diazotization of chromogenic radicals are key operations for ice-dye dye printing. It directly affects the vividness of colors and various color fastness. The accuracy of the ingredients has a great influence on the diazotization reaction. An excess of acid will reduce the coupling rate and the amount of small chromophores will not dissolve well. Excessive amount of sodium nitrite will cause insufficient amount of hydrochloric acid and nitrosation side reactions, and less amount of diazotization will be insufficient. There is also time, temperature, feeding speed and other factors will affect the stability of the color paste. The color paste is stable and the color is bright.

(2). Reactive dyes: The hydrolysis of reactive dyes has a great influence on the vividness of the flowers. Not only the amount of alkali chemicals should be mastered, but also the temperature of the paste must be low. Do not leave the paste, and the pulp should be used less frequently. Anti-stain salt S cannot be added.

(3). The pull element should adopt the triple cold operation method, so that the color paste is stable and the blackness is guaranteed.

The above slurry should be used softened water, softening water slurry not only save dye, and bright shade.

4. The influence of the printing operation on the vividness: To ensure that the color of the printed color is accurate, a knife must be added, and the pattern area is particularly small without a knife, which can be solved by adding freshwater white pulp.

5. The effect of steaming on the vividness: To strictly operate the steaming process, under normal circumstances, the solid color of baking is not pure and bright.

6. The effect of post-processing on the vividness: The post-treatment washing should be sufficient to ensure that the floating color is washed. Soaping temperature should be above 90 degrees.

7. Finishing the influence of the width on the vividness;

(1). From a theoretical point of view, tentering has no effect on the vividness of flowers, but if the tenter is used, the heat source is gas. Because the gas does not purify and contains sulfur, sulfur affects the shade of reactive dyes.

(2). The temperature of the tenter: The temperature is too high and the light is dark. For example, when the active yellow-brown K-GR temperature exceeds 145 degrees, the color light becomes dark and yellowish.
