Gas permeation type textile printing and dyeing process

Abstract

The invention discloses a gas permeation type textile printing and dyeing process, and belongs to the technical field of textile. By simplifying an existing drying process, after infrared preliminary drying is conducted, gas permeation powder is filled and laid on the surface of woven cloth, and then a color fixing mother disc is sealed and covered; then a magnetic field is applied to force the color fixing mother disc to extrude the gas permeation powder into pores of the woven fabric, so that the gas permeation powder is dissolved in residual water in the woven fabric, the gas permeation powder releases a large amount of gas after chemical reaction, the gas rapidly permeates and expands in the woven fabric, and the water only provides a carrier for the chemical reaction and does not participate in the chemical reaction, so that the dye is not prone to migration; the color fixing mother disc is reversely extruded to release a color fixing liquid for exchange after the gas is expanded to a certain degree, the color fixing liquid enters the woven fabric along a gas permeation track, and the non-migrated dye is fully and uniformly subjected to color fixing treatment. Compared with the prior art, the drying and color fixing procedures are simplified; and meanwhile, the dyeing effect of the woven fabric is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of textiles, and more specifically relates to an air-permeable textile printing and dyeing process. Background technique [0002] The textile industry is a traditional pillar industry in my country, including five parts: textile, printing and dyeing, chemical fiber, clothing and textile special equipment manufacturing. With the rapid development of the national economy, my country's printing and dyeing industry has also entered a period of rapid development, the level of equipment and technology has been significantly improved, and the production process and equipment have been continuously updated. [0003] The printing and dyeing process refers to the general term for the physical and chemical treatment of various textile materials during the production process, including the pretreatment, dyeing, printing and finishing processes of textile materials, collectively referred to as the printing and dyeing pro...

Problems solved by technology

[0004] At present, the common dyeing-drying-fixing process in the printing and dyeing process is to achieve better dyeing effect. The dyes on the fabric can be evenly distributed on the fabric to provide the necessary conditions for the color fixing process. In the prior art, the method of infrared drying-hot air drying-drum heating is generally used, and the hot air drying has a positive effect on the fabric. Non-contact heating is adopted on the opposite side to further reduce the amount of liquid carried on the fabric. This heating method will cause a certain migration of the dye, thereby reducing the subsequent color fixing effect
