Abstract

The invention discloses a one-bath quick-bleaching agent for printing and dyeing and a preparation method and application of the one-bath quick-bleaching agent. The quick-bleaching agent comprises a component I, a component II and a component III, wherein the mass ratio of the component I to the component II to the component III is 1: 1: 2; The component I comprises a fiber amorphous region channel expanding agent accounting for 88% of the total mass of the component I, and the balance of water; the fiber amorphous region channel expanding agent comprises the following components in percentageby mass: 30-40% of benzyl benzoate, 10-15% of diethylene glycol phthalate or dipropylene glycol phthalate, 20-25% of dibutyl maleate, 15-25% of fatty alcohol-polyoxyethylene ether and 5-10% of ethylene glycol butyl ether; the component II comprises a dispersing agent accounting for 9-12% of the total mass of the component II and the balance of water; and the component III comprises a dye antioxidant accounting for 25-30% of the total mass of the component III and the balance of water. The preparation method is simple and feasible; a large amount of water can be reduced by adopting the quick-bleaching agent for printing and dyeing, the cost is reduced, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing auxiliaries, in particular to a one-bath fast bleaching agent for printing and dyeing and its preparation method and application. Background technique [0002] In the traditional process of textile printing and dyeing, the traditional process of polyester / cotton fabric needs to be pre-treated first, bleaching cotton under alkaline and hydrogen peroxide conditions, washing and then dyeing polyester with disperse dyes under acidic conditions. During this process, a large amount of wastewater is generated, which increases the burden on sewage treatment and pollutes the environment. At the same time, a large amount of steam is generated, and energy consumption, time and labor costs remain high. Therefore seek a kind of speed bleaching agent that can not only bleach cotton when dyeing polyester on disperse dyes, but also do not affect the depth and shade of dyed polyester fibers on disperse...
