Abstract

The invention provides a color fixing agent used for cloth. The color fixing agent comprises the following raw materials in parts by weight: 16-20 parts of polydimethyl diallyl ammonium chloride, 11-15 parts of hydroxypropyl trimethyl ammonium chloride chitosan, 2-6 parts of lauryl alcohol polyoxyethylene ether, 10-14 parts of epoxy chloropropane, 16-20 parts of ethanol, 6-9 parts of sodium polyacrylate, 20-24 parts of hydroquinone, 2-4 parts of a catalyst and 35-45 parts of deionized water. The color fixing agent has the beneficial effects that (1) the color fixing agent is good in color fixing effect, high in persistence and strong in environmental protection property and has no harm to human bodies and the environment; (2) the color fixing agent is simple in production process and low in production cost and raw material cost. Therefore, the color fixing agent is suitable for mass production and extensive use.

Description

technical field [0001] The invention relates to the field of non-woven fabric processing, in particular to a color-fixing agent for fabric and a preparation method thereof. Background technique [0002] Fixing agent is one of the important auxiliaries in the printing and dyeing industry. [1] In recent years, with the development of science and technology, dyeing and finishing technology has also been significantly improved, due to the expansion of international textile trade and people's living standards, environmental awareness The improvement of textiles requires comfort, cleanliness and safety. Since Germany first launched the "Blue Angel" plan 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 of textiles. Green textiles require that the carcinogenic, teratogenic and biodegradable dyes and chemicals produced by certain aromatic amine in...
