Problems solved by technology

These methods are very effective in improving the color fastness to chlorine, but because most of the chlorine-resistant color-fixing agents used in these methods are water-soluble rigid polymers with aromatic rings, they have a negative impact on the feel and shade of the fabric. Problems such as fabric color change, hard hand feeling and poor washability

Abstract

The invention discloses a chlorine fastness improver, and a preparation method and an application thereof. The chlorine fastness improver comprises, by mass, 1-5% of polyacrylate, 5-48% of a hydrazide derivative, 0.5-6% of a dispersant, and the balance of water. The hydrazide derivative concretely is one or more of octanedioic dihydrazide, azelaic dihydrazide, sebacic dihydrazide, dodecanedioic dihydrazide, isonicotinoylhydrazine, 1,2-diisonicotinic acid hydrazide, 1,2-dimethyl-1,2-dibenzoylhydrazine and isophthalic dihydrazide. The preparation method of the chlorine fastness improver is simple, and the chlorine fastness improver makes chinlon and spandex swimming suit dyed fabrics have the advantages of effectively improved chlorine fastness, small color change, good handle, good chlorine fastness and good water wash resistance.

Description

technical field [0001] The invention relates to a chlorine-resistant enhancer and its preparation method and application, belonging to the technical field of textile dyeing and finishing. Background technique [0002] Swimming pools must add a certain amount of chlorine water to sterilize and disinfect. Swimming suits will fade and change color after being soaked in chlorine-containing swimming pool water for a long time, resulting in a great change in the color and light of swimsuits, which deviates from the original style and affects the wearing experience of consumers. . Therefore, the color fastness to chlorine water is an important performance index of swimwear fabrics, and its color fastness to chlorine is usually required to reach level 4 or above (up to level 5). In order to improve the chlorine-resistant color fastness of polyamide spandex swimwear fabric, post-treatment with chlorine-resistant color-fixing agent is required.
