Detergent and preparation method thereof

Abstract

The invention provides a detergent and a preparation method thereof. The detergent is prepared from polyvinylpyrrolidone (PVP), sodium polyacrylate PAAS, fatty alcohol-polyoxyethylene ether AEO-9, sodium dodecyl sulfate SDS, sorbitan laurate PEG-80 and water. The detergent has the functions of strong wetting, permeation, dispersion, emulsion, detergent washing, reprecipitation resistance and other functions, and resists hard water; the stained fastness, the dry friction fastness and wet rubbing fastness of a soaped fabric can be improved, and the color is even and the color is bright; the COD (Chemical Oxygen Demand) of the emitted waste water can also be reduced, the treatment cost of the printing and dyeing sewage can be lowered, and safety and environment protection can be achieved.

Description

technical field [0001] The invention relates to a cleaning agent and a preparation method thereof. Background technique [0002] Cleaning agent is a substance used to remove various impurities, dirt, auxiliaries and sizing remaining on fibers or their fabrics during the printing, dyeing and finishing processes. Cleaning is the key process of fabric dyeing post-treatment, and the quality of cleaning effect directly affects the quality of finished dyed fabrics. The research on efficient detergent and its cleaning process plays an important role in improving washing efficiency and color fastness, reducing waste water discharge and pollution, and saving energy and reducing consumption. It can be seen that detergent is a very important auxiliary agent in the printing and dyeing industry and plays a pivotal role. With the development of the printing and dyeing industry, the research on cleaning agents has also made great progress, and many corresponding cleaning agents with diff...

Problems solved by technology

For example, when fabrics such as cellulose fibers are dyed with reactive dyes, a considerable part of the dyes are hydrolyzed when they do not form covalent bonds with the fibers, and some hydrolyzed dyes are adsorbed to the surface of the fibers to form floating colors that are not combined with the fibers, seriously affecting The color fastness of dyed products, so reactive dyes must be soaped after dyeing. Now many reactive dye cleaning agents have been developed, but there are still many defects. How to improve the floating color removal rate and product quality has become our Issues to be Solved

Soaping with traditional soaping agents is generally carried out under relatively high temperature conditions, which has the disadvantages of energy consumption and high color of the lotion. Traditional detergents also have problems such as insufficient color fastness and serious environmental pollution.
