Abstract

The invention discloses an environment-friendly dyeing method of chinlon and cotton blended fabric. The method comprises the following steps: adding natural dye into a dye vat filled with a mixed solution of ethanol and deionized water to prepare a dye solution; immersing the blended fabric into the deionized water, adding tea saponin and calcium carbonate, then heating and carrying out ultrasonictreatment, then immersing the blended fabric into an organic acid solution, and then dehydrating and drying the blended fabric; putting the blended fabric into the dye solution, and carrying out ultrasonic dyeing; and washing the blended 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 materialswhich are safe and harmless to human bodies, and after dyeing, the blended fabric is high in soaping color fastness and free of chromatic aberration between polyamide fiber and cotton fibers.

Description

technical field [0001] The invention relates to the technical field of blended fabrics, in particular to an environment-friendly dyeing method for nylon and cotton blended fabrics. 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, natural 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,...
