Dyeing method of wool fibers

Abstract

The invention belongs to the technical field of textile dyeing, and particularly relates to a dyeing method of wool fibers. The method comprises the following steps: (1), preprocessing the wool fibers, specially, firstly mixing propolis, ethanol and water; performing microwave processing; then adding the wool fibers; soaking the wool fibers and then performing ultrasonic treatment for 20 to 40 minutes; then adding a yeast aqueous solution and performing ultrasonic treatment again; then fumigating the wool fibers by using rice water at 75 to 90 DEG C and then soaking the wool fibers in an ethanol solution; finally, washing the wool fibers with water and performing vacuum drying; (2) performing dip dyeing; (3) performing post-processing; (4) washing; (5) fixing color. According to the dyeingmethod of wool fibers disclosed by the invention, the wool fibers are preprocessed, so that loss of strength of the wool fibers due to dyeing is reduced, the colour fastness to washing and fastness to wet rubbing of the dyed wool fibers are good, the wool fibers soft handfeel, and the quality of the wool fibers is improved.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing, and particularly relates to a dyeing method for wool fibers. Background technique [0002] As a natural protein fiber, wool fiber has excellent heat retention and is widely used. The dyeing of wool fiber makes its application more diverse, and in traditional dyeing, in order to make the dyeing effect of wool fiber better and the dyeing more uniform, wool fiber is usually dyed at high temperature, and some will be treated with alkali, which will last a long time. The high temperature for a long time causes the loss of the strength of the wool fiber, the fiber strength is reduced, and the quality of the product is affected. [0003] In the prior art, in order to reduce the loss of wool fiber strength by dyeing, a low-temperature printing and dyeing method is usually adopted, but there are common defects such as long dyeing time, complicated process and poor color fastness. SUMMARY OF THE ...

Problems solved by technology

Dyeing wool fiber makes its application more diversified. In traditional dyeing, in order to make the dyeing effect of wool fiber better and more uniform, wool fiber is usually dyed at high temperature, and some of them will be treated with alkali. The continuous high temperature makes the strength of wool fiber lose, and the fiber strength decreases, which affects the quality of the product

[0003] In the prior art, in order to reduce the loss of wool fiber strength due to dyeing, low-temperature printing and dyeing methods are usually used, but there are common defects such as long dyeing time, complicated process, and poor color fastness.
