Production process and production equipment of rayon cotton and linen product cloth

Abstract

The invention relates to the field of printing and dyeing processes, and particularly discloses a production process and production equipment of rayon cotton and linen product cloth. The production process comprises the following steps that S1, flattening is carried out; S2, oxygen bleaching is carried out, specifically, an oxygen bleaching agent is prepared, and the cloth continuously passes through the oxygen bleaching agent; S3, washing is carried out with water; and S4, dyeing is carried out. The oxygen bleaching agent is prepared from water, caustic soda liquid with the concentration of 3-5 g / L, sodium carbonate with the concentration of 1-2 g / L, hydrogen peroxide with the concentration of 3-10 g / L, a refining agent with the concentration of 2-3 g / L, a stabilizer with the concentration of 1-2 g / L and a chelating agent with the concentration of 0.5-1 g / L. The production process has the advantages that the difference of materials among batches is small, the stability is high, and the use of water resources is reduced.

Description

technical field [0001] This application relates to the field of printing and dyeing technology, and more specifically, it relates to a production process and production equipment for rayon, cotton and linen products. Background technique [0002] Rayon is a silky man-made fiber composed of cellulose, the main component of plants, and has the same properties as cotton and flax fibers; cotton and linen are natural fibers extracted from plants. [0003] Before dyeing rayon and cotton, it is necessary to remove the cottonseed husks in the fabric to improve the flatness of the fabric and ensure the subsequent dyeing effect. Cottonseed hulls are now mainly removed using the oxygen bleaching process. In the related art, for flat style fabrics, generally the fabrics are leveled, oxygen bleached (boiled), washed and then dyed; or overflow), washed with water and then dyed. [0004] The specific operation of oxygen bleaching is as follows: a batch of fabrics corresponds to a tank o...

AI Technical Summary

Problems solved by technology

[0005] In the above-mentioned related technologies, the thermal bleaching between each batch of fabrics is intermittent production, and there are differences in the environment and processing parameters during thermal bleaching; while the effect of oxygen bleaching will directly affect the subsequent dyeing, resulting in differences in the color of the fabrics , leading to large differences between batches of cloth
