Problems solved by technology

[0003] The price of traditional pure cotton yarn has risen sharply, and most consumers now recognize chemical fiber products. The blended knitting products of acrylic fiber, wool and cupro fiber have increased significantly and are very popular among consumers. However, the acrylic fiber, wool and cupro fiber Three kinds of raw materials with different properties are dyed by one-bath method, which tends to lose sight of the other, resulting in low utilization rate of dyes, poor dyeing quality, and great difficulty in processing technology

Embodiment 1

[0020] Embodiment 1: as figure 1 Shown, 40 S Acrylic / wool / cupro (70 / 10 / 20) black knitted fabric dyeing method in one bath and two stages, the steps are as follows:

[0021] (1) Pretreatment: Put the acrylic / wool / cupro fiber blended knitted fabric into the dyeing vat, add cold water to the dyeing vat and control the bath ratio to 1:4.5; add degreasing agent and ice to the dyeing vat in sequence every 3 minutes Acetic acid (HAC), leveling agent, anti-sedimentation agent for one bath; add cationic dyes into the dyeing bath evenly and slowly (10-15min), after 5 minutes, add weak acid dyes evenly and slowly (10-15min), 10 Minutes later, raise the temperature to 75°C±2 at a speed of 1°C / min and keep it for 10-15min, then raise the temperature to 85°C±2 and keep it for 10-15min, then raise the temperature to 96-98°C, keep it for 60min, and finally heat it at 1°C Cool down at a speed of 1 / min, drain and wash water to prevent oil spots;

[0022] (2) Dyeing acrylic / wool / cupro fibers:...

Embodiment 2

[0027] Example 2: 60 S Acrylic / wool / cupro (35 / 30 / 35) beige knitted fabric dyeing method in one bath and two stages, the steps are as follows:

[0028](1) Pre-treatment: Put the acrylic / wool / cupro fiber blended knitted fabric into the dyeing vat, add cold water to the dyeing vat and control the bath ratio to 1:4; add degreasing agent and ice to the dyeing vat in sequence every 3 minutes Acetic acid (HAC), leveling agent, anti-sedimentation agent for one bath; add cationic dyes into the dyeing bath evenly and slowly (10-15min), after 5 minutes, add weak acid dyes evenly and slowly (10-15min), 10 Minutes later, raise the temperature to 75°C±2 at a speed of 1°C / min and keep it for 10-15min, then raise the temperature to 85°C±2 and keep it for 10-15min, then raise the temperature to 96-98°C, keep it for 60min, and finally heat it at 1°C Cool down at a speed of 1 / min, drain and wash water to prevent oil spots;

Abstract

The present invention provides a one-bath two-stage dyeing method for acrylic / wool / cupro blended knitted fabrics, which is characterized in that the process steps include (1) pretreatment, (2) dyeing acrylic / wool / cupro, ( 3) Neutralization, (4) Soaping, (5) Color fixing. Put a variety of dyes and auxiliaries in the same dyeing bath, by changing the temperature and pH value of the dyeing bath in different dyeing time periods, so that cationic dyes, weak acid dyes, and reactive dyes can achieve the best dyeing conditions to achieve multi-color dyeing. Simultaneous dyeing of fibers with different properties, thus simplifying the production process and improving production efficiency. The utilization rate of the dye and the dyeing quality are improved, and at the same time, a large amount of water resources can be saved, the discharge of sewage can be reduced, and it is beneficial to environmental protection.

Description

Technical field [0001] The present invention involves the dyeing method of textiles, especially a method of dyeing in two segments of acrylic / hairy / copper ammonia fiber -blended fabric. Background technique [0002] With the enhancement of human society's awareness of environmental protection and energy conservation, people pay more and more attention to the development and research of environmental protection, energy conservation, and efficient products.For the printing and dyeing industry that energy consumption and pollution are more serious, the development of energy conservation, efficient, and environmentally friendly textiles by improving technology has become the development direction of today's dyeing and rectification.The traditional two -bath method dyeing not only causes a waste of water resources, but also has more processes, long process processes, time -consuming and labor -intensive, and secondary dyeing.Low efficiency and high sewage volume.In order to solve the ...
