Problems solved by technology

Part of the equipment adopts pad dyeing process → padding lye → steaming two times of liquid dyeing process. Although it was the most advanced continuous pad dyeing process of towel fabric at that time, because the dyeing process before and after dyeing was processed in a rope shape, the product poor quality stability
At the same time, the products produced by continuous pad dyeing have obvious differences in style compared with intermittent production methods such as overflow machines, and cannot meet the needs of domestic and foreign customers.

Abstract

The invention relates to a reactive dye continuous pad-dyeing shorted and wet steaming machining process for towel and quilt fabrics, which is characterized in that an oil pressure evenness calender is selected and used; the liquor retention is controlled in the range of 90 to 100 percent; the adoption of a low-capacity trough ensures that the exchange of dye liquor is completed in a short time; saturated steam is used in a steaming box, so that the influence of the towel and quilt fabrics with high liquid taking quantity on the temperature and the humidity after the towel and quilt fabrics enter the steaming box is reduced; a special dye liquor stabilizer for reducing the hydrolyzation speed of dye is added into the dye liquor; and the dyeing is completed under the temperature and humidity conditions regulated by the process. The process has the advantages of high production efficiency, low energy consumption, low labor intensity, low environmental pollution, low aberration and stable product quality.

Description

technical field [0001] The invention relates to a wet short-steaming process for continuous pad dyeing of towel fabrics with reactive dyes, and belongs to the technical field of textile printing and dyeing. Background technique [0002] At present, the dyeing of towel fabrics is mainly produced by intermittent methods such as overflow machines, which not only have low production efficiency and large cylinder difference, but also high water consumption, energy consumption, and large wastewater discharge. In order to solve the problems of low efficiency and high consumption in batch production, cold batch dyeing technology has been developed at home and abroad. However, due to the thick fabric of the towel quilt, the stacking time is long, the production batch is very small, and the production efficiency is difficult to improve. Dyeing and finishing quilt fabrics by continuous pad dyeing can greatly improve production efficiency, reduce energy consumption, and realize energy ...
