Problems solved by technology

However, when dyeing and printing existing pure wool fabrics, there are the following problems: 1. The invisible damage to wool fabrics in the pre-dyeing and printing process is relatively large. The safety of raw materials is poor, and the consumption is large, which is easy to cause waste of resources, increase the discharge of pollutants, and pollute the environment; 3. The color fastness of wool fabrics after printing and dyeing is poor

Embodiment 1

[0030] A dyeing and printing process for wool fabric, comprising the following steps:

[0031] (1) Chlorine-free anti-shrinking treatment: the wool fabric is immersed in a composite enzyme anti-felting finishing solution with a temperature of 45°C, and a dipping and one rolling treatment is performed. The composite enzyme anti-felting finishing solution includes raw material components and The mass percentage is: silicone resin 26%, amylase 10%, pectinase 9%, potassium hydrogen sulfate 12%, softener 5%, water 38%;

[0032] (2) Washing and pre-drying: Wash the wool fabric after the chlorine-free anti-shrinkage treatment in step (1), and then pre-dry it at 75°C for 15 minutes;

[0033] (3) Bleaching and dyeing: the wool fabric treated in step (2) is dipped into the dyeing solution for two dips and two pads, and during the second soaking process, the temperature of the dyeing solution is raised to 100°C for thermal insulation dyeing;

[0034] (4) Color fixing: Immerse the wool f...

Abstract

The invention discloses a dyeing and printing processing technology of wool fabric. The technology comprises the steps as follows: (1) chloride-free shrink-resistant treatment: the wool fabric is impregnated in a complex enzyme anti-felting finishing solution for single-padding and single-rolling treatment, wherein the complex enzyme anti-felting finishing solution is prepared from raw material components in percentage by mass as follows: 25%-30% of organic silicon resin, 18%-22% of complex enzyme, 10%-15% of potassium hydrogen sulfate, 4%-8% of a softening agent and 30%-40% of water; (2) washing and pre-drying; (3) bleaching and dyeing; (4) fixation; (5) washing and drying; (6) setting. The technology is simple and easy to control, shrink-resistant, bleaching and dyeing and setting treatment is adopted, the printed and dyed wool fabric is ensured to have the stable size and good color fastness, and the technology has the advantages that the water and power consumption is low and energy saving and emission reduction effects can be realized, accords with the development trend of the dyeing and printing industry and has broad market prospects.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a dyeing and printing processing technology for wool fabrics. Background technique [0002] With the development of science and technology and the improvement of people's living standards, consumers have transitioned from simply paying attention to fabric texture to wanting equal attention to health, environmental protection and fashion coordination. Changing the appearance, feel, fashion, safety and environmental performance of fabrics through dyeing, printing processes and the selection of dyeing and printing raw materials is an effective means to achieve this trend. However, when the existing pure wool fabric is dyed and printed, there are the following problems: 1. The invisible damage to the wool fabric is relatively large during the pre-dyeing and printing process. The safety of raw materials is poor, and the dosage is large, which is easy to cause wast...
