Description

Technical Field

[0001] The invention relates to the technical field of textile fabrics, in particular to a production process of a fried color style fabric. Background Art

[0002] At present, there are many methods to obtain irregular colored fabrics in this field, mainly using tie-dyeing, printing and color frying. Among them, tie-dyeing art is a technology of spinning first and then dyeing. Its process characteristics are to use threads to twist the fabric to be printed and dyed into knots, and then print and dye. Through the tying technique, various patterns are formed. The production of tie-dyeing is overly dependent on manual work, resulting in low output and high cost. Printing is to design a pattern and apply it to the fabric by direct spraying, transfer printing or scraping to obtain a colored fabric, but the printing effect is not as natural as on the ready-made clothes, especially the printing effect at the seam is more unnatural, and the printing process cost is also high.

[0003] The color frying mainly involves frying the color stripping agent. The color will be single after frying. The specific process is to soak the dry pumice with potassium permanganate solution, and then stir and polish it together with the fabric, so that the dye at the friction point is oxidized by potassium permanganate, making the cloth surface irregularly faded, forming a white effect similar to flying snowflakes.

[0004] CN101403198A "A Colored Cloth" and CN104963215A "A Fabric Art Dyeing Method" disclose a method of using multiple types of dyes to dye the base color and the surface color twice, and then using the difference in dye soap fastness between the surface color and the base color to achieve the effect of irregular colored fabrics. The process of this scheme is complicated, and the surface color is mostly sulphurized, reduced or painted; sulphurized and reduced dyes are organic dyes, and a large amount of organic volatiles will be emitted during the dyeing process, and the finished dyed products will also emit organic volatiles for a period of time, which is no longer in line with the theme of green environmental protection in today's world; in addition, the paint-dyed fabrics also have poor hand feel and are not bright enough. Summary of the invention

[0005] 1.
