Problems solved by technology

In the household washing process, it is impossible to wash one piece alone. When clothes of different colors are washed together, the problem of mixed staining often occurs, which affects the washing effect. What is more serious is that the quality and grade of high-end products are greatly affected. Destruction, domestic sewage containing dyes will also pollute the environment
Usually the solution to this problem is to add a little salt to reduce the degree of fading, or to wash the faded clothes separately, but these two methods are very troublesome and the effect is not obvious

Abstract

The invention discloses an accessory for preventing union dyeing and solves the problems of color losing and union dyeing of medium-dark clothes during current clothes washing process.The accessory comprises nonwoven cloth which contains union-dyeing-preventive ingredients, the union-dyeing-preventive ingredients include trimethyl benzyl ammonium chloride, epoxy organosilicon quaternary ammonium salt, chitosan quaternary ammonium salt, oxalic acid, sodium polyacrylate, phthalate and 2-(4-thiazolyl)benzimidazole.Chemical accessories having ultrahigh absorption fading capability and color locking capability are adhered on the nonwoven, color faded in the process of clothes washing can be fixed to avoid causing pollution to other clothes different in color, quality and grade of clothes are guaranteed, convenience during clothes washing is improved greatly, time is saved, and quality and efficiency of family life are improved.

Description

technical field [0001] The invention relates to the printing and dyeing industry, in particular to an auxiliary material made of nonwoven fabric for preventing mutual dyeing in the washing process of fabrics. Background technique [0002] As we all know, direct dyes and acid dyes are only bound to fibers by van der Waals force and hydrogen bonds, and their washing fastness is poor in wet environments; reactive dyes are bound to fibers by covalent bonds, and their washing fastness is also very general, but in dyeing 1. When the color is dark, its washing fastness is relatively low; when it is dyed with insoluble azo dyes and sulfur dyes (including liquid sulfur dyes), its washing fastness is not ideal. Although the dyeing process and materials used are different for the clothes you buy every day, most of them have the problem of fading after washing, especially dark clothes. In the household washing process, it is impossible to wash one piece alone. When clothes of different...
