Problems solved by technology

This method needs to pre-treat the two fibers first, then dye them separately, and then blend the two fibers with the same dyeing effect. This will be limited by the dyeing equipment, and it is also difficult to achieve a level dyeing effect.
The process of this method is complex, consumes a lot of energy, and the cost is high

Abstract

This invention discloses one process method to improve crust or cotton mixture dying property, which comprises the following steps: adopting anode ion etherifying agent, alkaline agent and other assistant agent before mixture fabric dying. This invention adopts cation crust or cotton mixture fabric for pre-process for dying, which improves the cotton fiber direct property and reduce dying rate difference on curst fiber and mixture fabric even dying.

Description

technical field [0001] The invention relates to a method for dyeing chitin / cotton blended fabrics, in particular to a method for improving the dyeing levelness of chitin / cotton blended fabrics. Background technique [0002] Chitin fiber has good adsorption, cohesiveness, bactericidal, breathable, sweat-absorbing and moisturizing properties, and is naturally biodegradable. The fabric made of chitin fiber and cotton fiber (ie chitin / cotton) has the characteristics of firmness, no wrinkle or shrinkage, bright color, good sweat absorption performance, not easy to fade and excellent antibacterial properties, and has attracted people's attention in recent years. . However, due to the difference in chemical structure and performance between the two, it has become a major technical difficulty to achieve the same color when dyeing blended fabrics with reactive dyes. [0003] The chitin fiber macromolecules contain amino groups and hydroxyl groups. Amino groups can absorb hydrogen i...
