Boiling-off coloring device for textile fibers

Abstract

The invention relates to a boiling-off coloring device for textile fibers. The device comprises a first device body, a first cavity is formed in the first device body, a boiling-off additive and caustic soda are added into the first cavity, and the boiling-off additive, the caustic soda and impurities, such as waxy substances and cotton seed hulls, in the textile fibers can be subjected to a chemical degradation reaction. According to the device, the textile fibers are subjected to boiling-off, dried and colored, the device conducts stirring while boiling-off is conducted, so that the boiling-off additive and caustic soda are sufficiently mixed with the textile fibers, the efficiency of removing the impurities of the textile fibers is high, and convenience is provided for following coloring for the textile fibers; the direction of the extrusion force generated by an L-shaped long plate on the surfaces of the textile fibers is opposite to the movement direction of the textile fibers, the device has a good extrusion effect, the boiling-off additive and caustic soda are recovered into the first cavity for recycling, the device is environmentally friendly, the textile fibers are dried,so that micropores in the fibers are heated to be expanded, diffusion during following coloring is quick and even, and the device has a good coloring effect, is high in overall automation degree andcan achieve circulation production.

Description

technical field [0001] The invention relates to the field of fiber coloring, in particular to a textile fiber scouring and coloring device. Background technique [0002] As we all know, there are various natural impurities in cotton textile fibers, such as: pectin, waxy substances, cottonseed hulls, etc. These impurities reduce the permeability of textile fibers in textile fibers, and the decrease in permeability will seriously affect the subsequent During the coloring process, the coloring agent diffuses inside the fiber, thereby reducing the coloring efficiency; therefore, the textile fiber needs to be scoured before being colored; the traditional scouring method is to directly pour the textile fiber into a tank with scouring aids and caustic soda In the large pot, the textile fibers treated in this way are easy to knot in the liquid, which affects the subsequent collection of the textile fibers in the drum; at the same time, the traditional scouring and coloring require t...

[0002] As we all know, there are various natural impurities in cotton textile fibers, such as: pectin, waxy substances, cottonseed hulls, etc. These impurities reduce the permeability of textile fibers in textile fibers, and the decrease in permeability will seriously affect the subsequent During the coloring process, the coloring agent diffuses inside the fiber, thereby reducing the coloring efficiency; therefore, the textile fiber needs to be scoured before being colored; the traditional scouring method is to directly pour the textile fiber into a tank with scouring aids and caustic soda In the large pot, the textile fibers treated in this way are easy to knot in the liquid, which affects the subsequent collection of the textile fibers in the drum; at the same time, the traditional scouring and coloring require two different devices for processing, and the scouring of the textile fibers Impurities in the external environment may be stuck during transportation, which will affect the subsequent coloring effect; in addition, the traditional scouring and coloring requires a long cycle, low production efficiency, and low automation; therefore, it is necessary to design a textile fiber scouring and coloring device to solve the above problems
