Abstract

The invention relates to a hydrophilic color fixing agent for cotton fabric. The hydrophilic color fixing agent for the cotton fabric is characterized by being prepared by polymerizing the following components: 5-30 parts of a vinyl pyridine compound, 30-90 parts of an amine compound, 5-40 parts of an acrylic compound, 5-50 parts of a solvent, 0.02-3 parts of an initiator and 5-30 parts of neutralizing acid. The hydrophilic color fixing agent for the cotton fabric has the beneficial effects as follows: the hydrophilic color fixing agent for the cotton fabric does not affect the hydrophilicityand the hand feel of the fabric itself and can achieve a good color fixing effect.

Description

technical field [0001] The invention relates to a hydrophilic color-fixing agent for cotton fiber fabrics and a preparation method thereof. The hydrophilic color-fixing agent does not affect the hydrophilicity and hand feeling of the fabric itself, and at the same time can achieve the color fastness of traditional color-fixing agents Spend. technical background [0002] Cotton fiber fabrics have good hygroscopicity, warmth retention and soft hand properties and play an important role in fabric fibers. Cotton fiber dyeing mainly includes reduction, direct vulcanization and reactive dyes, etc. Among them, reactive dyes have achieved rapid development because of their broad color spectrum, economy, and environmental protection. The color-fixing agents for reactive dye cotton on the market have mainly experienced dicyandiamide formaldehyde resin-type color-fixing agents, polyamine-type resin-type color-fixing agents, polycation-type color-fixing agents, reactive resin color-fix...
