Green and environment-friendly wool composite fiber and refining method and application thereof

Abstract

The invention discloses a refining method of green and environment-friendly wool composite fiber. The refining method comprises the following steps that an environment-friendly penetrating agent is dissolved in ethanol water, low-temperature uniform stirring is conducted, wool tops are immersed in the solution, the solution is sent into a wool acid dissolving auxiliary, the solution is taken out,lifted and subjected to standing, redundant liquid is removed, air drying is conducted, and pretreated wool fiber is obtained; and a reinforced viscose solution is sent into an impregnation tank, thepretreated wool fiber is added for ultrasonic treatment, then under extrusion and traction of a clamping roller, the reinforced viscose solution uniformly coats the pretreated wool fiber, the pretreated wool fiber is sent into a coagulating bath for coagulation, cleaning and drafting are conducted, the pretreated wool fiber is sent into a milk protein fiber spinning solution, and the green and environment-friendly wool composite fiber is obtained through curing, drafting, drying and shaping. According to the refining method, a previous technology is broken through, the fiber can reach the fineness of a common refining technology, the mechanical property of the fiber is excellent, and the surface smoothness is high; and a preparation containing available chlorine or chemical agents such assodium pyrosulfite and sodium hydrogen sulfite are not adopted for treatment, and the refining method is safe, environmentally friendly and free of environmental pollution.

Description

technical field [0001] The invention relates to the technical field of wool fiber refinement, in particular to a green and environment-friendly wool composite fiber and its refinement method and application. Background technique [0002] Wool is a high-grade textile fiber material commonly used in the manufacture of textile products such as suits, fashion and knitted sweaters. However, the surface of wool has a special structure - the scale layer, which will cause felting of wool products during use, change the size and shape of the garment, and affect the appearance and performance of the garment; at the same time, the structure of the scale layer is tight, The brightness of wool products is insufficient, and the handle is not smooth and soft enough. [0003] With the continuous development of science and technology, people's requirements for the performance of fibers and their textiles are constantly improving, and textile products are developing towards high-level and hi...

Problems solved by technology

CN 103820991 B A method for modifying the surface of wool by catalytic oxidation. The aqueous dispersion of iron oxide nanoparticles is sprayed on the wool fibers so that the iron oxide nanoparticles are attached to the surface of the wool fibers, and then H 2 o 2 Solution catalysis, protease treatment, so that the surface scale structure is corroded and destroyed, and the descaling effect is achieved; CN102677450 B is a method for surface modification of wool, by using nano-TiO 2 Particles (Anatase TiO 2 Nanoparticles) are attached to wool and treated with ultraviolet light for photocatalytic treatment and protease treatment, so that the scale structure on the wool surface is partially corroded and destroyed; but the above two are not only difficult to control the degree of stripping, but also the mechanical properties of wool fiber decrease significantly

[0006] CN 105780447 B A method for modifying wool surface scales in a micro-water system. By preparing microcapsules containing sodium hydroxide, the corrosion of sodium hydroxide on wool is limited to only occur on the wool surface, so as to corrode the wool scale structure, although the use of chlorination is avoided. The problems caused by the descaling method, but a large amount of organic materials are introduced, and the surface gloss of the wool fiber is poor after corrosion

Although the existing wool stretching and thinning technology can use relatively thick wool fibers to produce thinner fibers, it is easy to generate a large amount of waste liquid and pollute the environment. At the same time, the surface smoothness of the thinned fibers is poor, and the mechanical properties drop significantly.
