Embodiment 1

[0023] After pre-treating the wool / nylon blended fabric, inject clear water into the tank, and then add dyeing auxiliaries to the dyeing bath, including Uniperol AR 0.8g / L, Albegal SET 1% (owf), Albegal B 1.6% (owf) , Yuanmingfen 6g / L, after running for 10min, add Lanasol Yellow CE 0.078%, Lanasol Red CE 0.014%, LanasolNavy CE0.016%, after running for 10min, add Lanacron Yellow N-2GL 0.057%, Lanaset Red G0.014 %, Lanaset Gray G 0.031%, after running for 10 minutes, heat up to 60°C at 1°C / min, keep warm for 15min, then heat up to 108°C at 0.6°C / min, keep warm for 30min, then cool down to 40°C, add acid release agent Albatex AB-45 0.9g / L, run for 10min, then raise the temperature to 108℃ at 0.8℃ / min, keep it warm for 30min, then cool down to 80℃, drain. Re-inject clean water, add 0.3g / L soda ash, heat up to 80°C, keep warm for 20min, and drain. Re-inject clean water, add glacial acetic acid 0.4g / L, run for 20min, and drain. Re-inject clean water, add nylon color fixing agent M...

Abstract

The invention relates to a colored light consistency dyeing method for wool / nylon blended fabric. The method comprises the following steps: placing pretreated wool / nylon blended fabric into a dye vat, injecting water, adding a dyeing auxiliary agent, running and adding a reactive dye for wool, running for 5-15 min, adding a neutral metal complex dye, running for 5-15 min, stepwise heating, cooling and adding an acid-releasing agent, running and then heating, cooling and draining; injecting water after draining, adding soda ash, and draining; injecting water, adding glacial acetic acid, and draining; injecting water, adding a dye-fixing agent, carrying out thermal insulation at 70 DEG C for 10-30 min, draying, and drying. By one-bath two-stage process for dyeing, the obtained fabric can greatly reach colored light consistency, the defect of uneven dyeing in the prior art is overcome, and the method is beneficial to application and development of wool / nylon blends.

Description

technical field [0001] The invention belongs to the field of dyeing of blended fabrics, in particular to a method for dyeing wool / nylon blended fabrics with consistent color and light. Background technique [0002] Wool is a high-grade protein fiber with excellent elasticity, plump feel and good thermal performance. Nylon is a polyamide fiber, which has the characteristics of good elasticity, high strength, good wear resistance, good moisture absorption and good air permeability. It is often used to blend with other fibers to improve the strength and other properties of the fiber. The advantages make the fabric have good wearing performance and unique style. [0003] Wool / nylon blends are often dyed with reactive dyes, acid leveling dyes, metal complex dyes and acid milling-resistant dyes to obtain consistent colors. The structural feature of nylon is that there are a large number of carbon chains and amide groups between its molecular chains, and only the ends of the mole...
