Dry cleaning and bleaching agent for wool

Abstract

The invention discloses a dry cleaning and bleaching agent for wool, which is characterized in that the agent is a mixed liquor composed of an aqueous hydrogen peroxide solution and an aqueous solution of a decontaminant with volume ratio of 1:1; the aqueous hydrogen peroxide solution is prepared by hydrogen peroxide with concentration of 50% and water according to volume ratio of 1:1-2; and the aqueous solution of the decontaminant is prepared by sodium alcohol ether sulphate and water by weight ratio of 1: 1-1: 1.5. The agent is uniformly sprayed on the wool, dry cleaning and bleaching for wool can be realized, a wool scouring production link can be cancelled, and dry cleaning and bleaching for the wool can be synchronously carried out, a lot of time and energy consumption can be saved, production efficiency can be greatly increased, production cost is reduced, water consumption is little, sewage is not generated, water resource is saved, and environmental pollution can be basically avoided.

Description

technical field [0001] The invention relates to a dry-cleaning bleaching liquid used for washing and bleaching wool. Background technique [0002] Raw wool (newly sheared wool) is used as a textile raw material, the lighter the color, the higher the whiteness, and the higher the grade of wool. Before textile processing, the raw wool needs to be cleaned and processed to become scoured wool, which is then made into tops; the tops are drawn and thinned on the spinning frame to become yarns, and finally enter the weaving process. The washed wool has a considerable whiteness, which can meet the general dyeing requirements. However, due to the natural light yellow color of wool, it affects the whiteness of wool. To achieve the requirements of easy coloring and bright color, it is necessary to minimize the amount of dyeing on wool. Under the premise of fiber strength damage, the wool is bleached to improve product quality and meet the market and user requirements for wool quality....

AI Technical Summary

Problems solved by technology

Washing wool not only wastes water resources, but also discharges the sewage with detergent and bleaching agent, pollutes water sources, and causes environmental pollution; bleaching agent uses pharmaceuticals such as sodium hydrosulfite and sodium pyrophosphate, which can easily damage wool

In short, this method can easily lead to rough wool feel and reduced strength, or yellowing and mildew of wool due to poor control of dry humidity; especially when the process conditions are not controlled properly, the wool fiber is seriously damaged, which not only affects the product quality, Moreover, it also brings negative impacts to the follow-up process; at the same time, it consumes a lot of resources such as electricity, coal, and groundwater; the processing cycle is relatively long, and a large amount of sewage is generated during the processing, and the cost of pollution treatment is relatively high, and the sewage is not treated or treated in place. Discharging out will pollute water sources and cause environmental pollution, affecting the lives of local residents
