Embodiment Construction

[0010] The following is further explained with examples:

[0011] (1) Take 100g of black dye, first dissolve it with 1000ml of alcohol, stir it evenly, add it into the prepared coagulation solution, stir it evenly, and prepare it into a black coagulation bath, when the spinning solution is sprayed from the spinneret into the coagulation bath , to form colored primary fibers, and then through drafting, washing, and drying to form black fibers.

[0012] (2) Take 150g of yellow pigment, first dissolve it with 1000ml of alcohol, stir it evenly, add it to the prepared coagulation solution, and then stir it evenly to make a black coagulation bath. When the spinning solution is sprayed from the spinneret into the coagulation bath , to form colored primary fibers, and then through drafting, washing, and drying to produce yellow fibers.

[0013] (3) Take 180g of red pigment, first dissolve it with 2000ml of alcohol, stir it evenly, add it to the prepared coagulation solution, stir it ...

Abstract

This invention relates to a colored chitose fiber production technique with coagulation bathing method, the character as follows: adding dyestuff in the coagulation bathe of the wet-processing spinning to obtain colored coagulation bathing solution, then the spinning solution is sprayed from the spray board to the coagulation bathing solution to form original colored fiber, then the original colored fiber is drawing, washing, drying to from colored fiber.

Description

technical field [0001] The invention relates to the field of colored fiber processing in the wet spinning process, in particular to a production method of colored chitosan fiber. Background technique [0002] Chitosan fiber is a high polymer fiber extracted from marine organisms. There is no method and technology for producing colored chitosan fibers at present. Chitosan fibers are used for textile dyeing, mainly including chitosan fiber blended yarn dyeing and gray cloth dyeing. However, due to the different coloring mechanism of chitosan fiber and other fibers, the blended yarn and gray fabric will form a large color difference between different materials during dyeing, which will affect the appearance quality of textiles. And this production technology can directly produce colored chitosan fiber, and the color difference problem that occurs when chitosan fiber is blended with other fibers can be solved by the method of color spinning. Contents of the invention [0003...
