Biological enzyme dye accelerator for wool fabrics

Abstract

The invention discloses a biological enzyme dye accelerator for wool fabrics. The biological enzyme dye accelerator comprises, by weight, 100 parts of complex enzymes, 20-30 parts of stabilizers, 15-19 parts of penetrating agents, 10-15 parts of lanthanum chloride, 9-11 parts of chitosan, 2-5 parts of pentane alcohol sodium phosphate ester, 6-9 parts of dodecylphenol ether and 40-60 parts of water. The invention further discloses a method for applying the biological enzyme dye accelerator for the wool fabrics. The biological enzyme dye accelerator and the method have the advantages that the biological enzyme dye accelerator is excellent in stability, and the excellent activity of the biological enzyme dye accelerator still can be kept even after the biological enzyme dye accelerator is stored for a long time; the wool fabrics can be dyed under low-temperature conditions after being finished by the aid of the biological enzyme dye accelerator, and are excellent in dye-uptake.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a biological enzyme dyeing accelerator for wool fabrics. Background technique [0002] Wool is a natural protein fiber, which has excellent hygroscopicity, warmth retention, air permeability, resilience, etc., and is widely used in various high-grade textile fabrics. However, due to the natural source of wool fiber, its structure is very different from that of ordinary chemical synthetic fibers. The scale layer on the surface of the fiber is hard and hydrophobic, which will significantly affect the adsorption of dye molecules, thereby increasing the difficulty of wool dyeing. In routine operations, wool is often heated to 90-100°C for high-temperature dyeing, but high-temperature dyeing not only increases operating costs, but also increases energy consumption and damages wool fibers. The consequences of wool damage during dyeing are: weight loss of wool and reduced yield; diff...

AI Technical Summary

Problems solved by technology

The solvent additive method is to add a small amount of solvent to the conventional liquid dyeing bath, so that the wool is dyed at 80°C. This method will cause serious environmental pollution due to the use of harmful organic solvents.

The formic acid method refers to the use of concentrated formic acid with a large bath ratio to dye at room temperature. Although it can make wool fabrics have a good dyeing effect at low temperature, the formic acid method requires high equipment and is easy to cause damage to wool fibers. It is also difficult to mass-produce

The urea method is to use the wool fabric to be dyed after being treated with urea, but the efficiency of urea is not high, and the subsequent dyeing effect is not good.

The low-temperature plasma method is to dye the fabric after plasma treatment, but the process of this method is relatively complicated and the cost is high
