AI Technical Summary

Technical Problem

Traditional anti-color bleeding technology is prone to failure under high temperature and strong water flow, cannot actively eliminate free dyes, and has limited effect on intercepting highly migratory dyes, damaging the feel and breathability of fabrics.

Method used

The dye molecular structure is altered through a complexation reaction using chelating agents and anti-blend agents, transforming it into a water-insoluble solid. Combined with components such as cellulose ether and povidone, a stable anti-blend solution is formed, suitable for a variety of fabric materials.

Benefits of technology

It maintains stable performance under high temperature or strong water flow, significantly reduces the risk of dye loss from dark-colored clothing, actively intercepts migrating dyes, and achieves long-lasting bright colors. It is suitable for fabrics such as cotton, linen, and chemical fibers.

Abstract

This invention relates to a dye-blocking liquid for clothing and its preparation method, belonging to the field of detergent technology. A liquid system is constructed using a specific ratio of chelating agents, dye-blocking agents, fixing agents, and rheology modifiers (cellulose ethers / povidone, etc.). Through a chemical complexation mechanism, it actively captures free dye molecules, converting them into water-insoluble inert precipitates. Simultaneously, dynamic dispersion technology ensures rapid penetration of the active ingredients into the fabric fibers. The technical effects are: overcoming the temperature-sensitive defects of traditional physical adsorption and the protective blind spots of fixing agents, achieving highly efficient interception and deactivation of dyes under high-temperature and high-flow environments; standard testing verifies that its dye-blocking performance significantly exceeds industry benchmarks, and the liquid formula leaves no residue, is suitable for various fabrics, provides comprehensive color protection for mixed-wash clothing, and fundamentally eliminates the risk of dye blockage.
