Abstract

The invention discloses a poly-cation color fixing agent, which comprises the following components in parts by weight: 20 to 40 parts of diethylene triamine, 20 to 40 parts of epoxy chloropropane, and 10 to 20 parts of dimethyl diallyl ammonium chloride. The invention also discloses a preparation method of the poly-cation color fixing agent. The provided poly-cation color fixing agent can achieve an excellent color fixing effect. Moreover, the color fixing agent does not generate formaldehyde during the process of production and application, and the textiles processed by the color fixing agent will not give off formaldehyde either.

Description

Technical field [0001] The invention relates to a fixing agent. Specifically, it relates to a polycationic color fixing agent and a preparation method thereof. Background technique [0002] Fixing agent is one of the important additives in the printing and dyeing industry. In recent years, with the development of science and technology, printing and dyeing technology has also been significantly improved. Due to the expansion of international textile trade and the improvement of people's living standards and environmental protection awareness, textiles are required to be comfortable, clean and safe. Since Germany first launched the "Blue Angel" program in the 1970s, some developed countries in the world (Japan, the United States, etc.) have successively passed and implemented relevant laws and regulations, stipulating various indicators for textiles. Green textiles are required to prohibit the use of carcinogenic, teratogenic, and poorly biodegradable dyes and dyes produced by c...
