Problems solved by technology

The free calcium and magnesium ions in the water combine with the anions in the soap or washing powder, and the raw precipitate adheres to the surface of the towel or clothing, making the towel or clothing hard after washing, while traditional finishing aids can soften the towel or clothing , but most of the softeners will have some toxic residues that will greatly damage people's health, and it will be even more harmful to children, especially when children touch or even inhale such softeners while playing, it will cause great harm to their health. harm

Abstract

The invention relates to an environment-friendly finishing auxiliary which comprises waterborne polyurethane, sodium acetate, sorbitan fatty acid ester, dimethyl octadecyl hydroxyethyl ammonium nitrate, perfume, sodium chlorate and water. The environment-friendly finishing auxiliary can well soften various fabrics such as chemical fiber fabric, cotton spinning fabric, silk weaving fabric and the like. The environment-friendly finishing auxiliary is nonhazardous during use, has aromatic odor, can be used as a softener for top-grade fabric, can soften fabrics hardened due to various reasons in life, is safe and nonhazardous in the use process and has good prevention effect on pilling and wrinkles of the fabric.

Description

technical field [0001] The invention relates to the field of chemical raw materials, in particular to environment-friendly finishing aids. Background technique [0002] Finishing auxiliaries are widely used in the textile printing and dyeing industry. With the development of society, people pay more and more attention to environmental protection, and many highly toxic and highly polluting finishing auxiliaries have been discontinued. For example, finishing auxiliaries containing monoalkyl quaternary ammonium salts are highly toxic and bio Poor degradability, etc. have been gradually eliminated; while the toxicity of dialkyl quaternary ammonium salts and alkyl acyl quaternary ammonium salts is lower than that of monoalkyl quaternary ammonium salts, but their biodegradability is very poor, they will kill biological bacteria and are easy to It is absorbed by sludge during sewage treatment and pollutes farmland. Some clothes will pill and wrinkle after long-term wearing. The ...
