Abstract

The invention relates to a dyeing method for improving deep dyeing performance of polyamide fiber, and belongs to the technical field of textile printing and dyeing. The dyeing method comprises the following steps: adding disperse dye into a mixed solution of ethanol and water to obtain a dyeing solution, and dyeing the polyamide fiber in an ultrasonic environment, wherein by virtue of strong penetration of ethanol into the polyamide fiber, a synergistic effect is produced under the auxiliary action of ultrasonic, and a large number of dye molecules are carried into the free volume of the fiber so as to deeply and thoroughly dye the polyamide fiber. By the dyeing method, the dyeing temperature is low, the dyeing time is short, strength damage of the polyamide fiber in the dyeing process is alleviated, and the problem that the dyeing depth is not high when the disperse dye dyes the polyamide fiber is effectively solved; and the dyeing method is simple in process and strong in operability and is an efficient polyamide fiber dyeing method.

Description

technical field

[0001] The invention relates to a dyeing method for improving the dyeing performance of nylon fibers, which belongs to the technical field of textile printing and dyeing processing. Background technique

[0002] Nylon fiber belongs to the category of polyamide fiber. The trade name is nylon. It has the characteristics of high strength and high elasticity. It is mainly used as the main raw material of elastic fabrics in the market, such as manufacturing swimwear, stockings, underwear and other textile products. Nylon fibers include polycaprolactam and polyhexamethylene adipamide, namely nylon 6 and nylon 66. Nylon fiber contains a large number of polar amino groups. Under certain conditions, it can be dyed with acid dyes, disperse dyes and other dyes. Nylon fibers dyed with acid dyes are bright in color, high in exhaustion rate, and easy to achieve the designed color.

[0003] When nylon fiber is dyed with acid dyes, the pH value of the dyeing environment is...
