Problems solved by technology

[0006] Direct action of dyes: the light groups of the flax macromolecules can be combined with dyes, but the flax macromolecules only have three light groups, and the crystallinity is high, so the amount of adsorption of dyes is limited, resulting in flax fibers The dye uptake and color fastness are not ideal

Abstract

An accelerating agent used for printing and dyeing of linen and a using method thereof are disclosed. The accelerating agent comprises following raw materials by weight: 2 parts of rare earth elements, 2 parts of chitosan, 1 part of sodium chloride, 15 parts of 2,4,5-trichlorophenol, 5 parts of citric acid and 100 parts of water. The using method of the accelerating agent used for printing and dyeing of linen is also disclosed. The method includes 1) fully stirring the components by mass to prepare the accelerating agent; 2) dipping linen into the accelerating agent having a temperature of 90 DGE C for 30 min, and treating with microwave having power of 70 W as assistant; 3) dipping the linen obtained in the step 2) into a caustic soda solution having a temperature of 85 DEG C for 50 min; 4) dipping the linen obtained in the step 3) into an acetic acid solution having a temperature of 45 DEG C for 20 min; and 5) dipping the linen obtained in the step 4) into a sodium carbonate solution having a temperature of 80 DEG C for 35 min.

Description

technical field [0001] The invention relates to a dyeing accelerator in the field of textile industry, in particular to a dyeing accelerator used in the printing and dyeing of linen fabrics and a use method thereof. Background technique [0002] Flax, also known as hemp and flax, is the oldest natural and environmentally friendly textile fiber in the world, and it is also one of the green products with the most development potential. Flax fiber is soft, strong, wear-resistant, good hygroscopicity, fast moisture conduction, and relatively fine, which is an excellent textile raw material; and flax is harmless to human health, and meets the needs of the current era of green, low-carbon, healthy, etc. elements of quality. Therefore, flax is an excellent environmentally friendly textile and clothing fabric with sustainable development characteristics. [0003] Both the chemical organization and the microstructure of flax have an adverse effect on the dyeing properties of flax. ...
