Abstract

The invention discloses a natural dye ultrasonic dyeing method of chinlon fabric. The method comprises the following steps: preparing a dye solution from natural dye; immersing the chinlon fabric intodeionized water, adding calcium carbonate, then heating and carrying out ultrasonic treatment, then immersing the chinlon fabric into an organic acid solution for soaking, dehydrating and drying; putting the chinlon fabric into the dye solution, and carrying out ultrasonic dyeing; and washing the chinlon fabric with water, and carrying out soaping, secondary rinsing with water, dehydrating, drying and shaping. According to the dyeing method, a large amount of organic dyeing aids do not need to be added for dyeing, only a small amount of calcium carbonate and organic acid need to be added in the dyeing process, the other raw materials are natural raw materials which are safe and harmless to human bodies, inorganic dye is adopted in the dyeing method of the chinlon fabric, and the soaping color fastness of the fabric can reach the fifth level.

Description

technical field [0001] The invention relates to the technical field of nylon dyeing, in particular to an ultrasonic dyeing method for nylon fabric with natural dyes. 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 generally acidic, and the pH ra...
