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

Embodiment 1

[0043] see figure 1 , an air-permeable textile printing and dyeing process, comprising the following steps:

[0044] S1. Take the woven fabric and install it on the unwinding machine for unwinding, and then send it through the singeing machine to complete the singeing process;

[0045] S2. Carry out desizing treatment to the woven fabric, then wash with water and carry out scouring and bleaching to remove residual size and impurities, and dry for later use;

[0046] S3. Dye the dried fabric by padding in the dye vat prepared with the dye solution. The bath ratio is 1:15, and it is treated at 60°C for 10 minutes, so that the liquid-carrying rate of the fabric reaches 80-90%, and then infrared rays are used. The method of drying reduces the liquid-carrying rate of the fabric to less than 50%;

[0047] S4. Unfold and spread the fabric onto the platform, then fill with a layer of air permeation powder, seal and cover the solid color master plate, apply a magnetic field under the...

Abstract

The invention discloses an air-permeable textile printing and dyeing process, which belongs to the technical field of textiles. The present invention can simplify the existing drying process and fill the surface of the woven fabric with air-permeable powder after preliminary infrared drying. , and then seal the color-fixing master plate on the airtight cover, and then apply a magnetic field to force the color-fixing master plate to squeeze the air-permeable powder into the pores of the woven fabric, thereby dissolving in the residual moisture in the woven fabric. After the chemical reaction of the air-permeable powder occurs A large amount of gas is released, and the gas penetrates and expands rapidly in the fabric. Since the water only provides the carrier of the chemical reaction and does not participate in the chemical reaction, the dye is not easy to migrate. The color master disk releases the color-fixing liquid for exchange, and the color-fixing liquid enters the fabric along the gas permeation track, and performs color-fixing treatment on the non-migrated dye fully and uniformly. Compared with the existing technology, it not only simplifies Eliminates the drying and color fixing process, and at the same time significantly improves the dyeing effect of the woven fabric.

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...
