Problems solved by technology

Now almost more than half of the sports shoes are made of fly-woven shoes. Although fly-woven shoes are light in weight and have good air permeability, when it rains or steps on a wet road, the upper will seep water immediately, and the inside of the shoe will get wet immediately. One of the biggest pain points of shoes
[0005] In the existing technology, ordinary high-elastic fibers are used to weave the fly-knit upper, and then the anti-splash finishing treatment is not resistant to washing. The basic standard will drop by 2-3 levels after washing 5 times, which is equivalent to continuous wearing for 1-2 weeks. The splash-proof effect is basically lost
In addition, the method of adding anti-splashing agent to the ordinary fiber through the cheese dyeing factory is not good in washing resistance, and it will drop by 1-2 grades after 5 times of standard washing
However, the anti-splash fiber of the applicant's previous research and development results cannot be processed into high-elastic fiber by secondary processing

Embodiment 1

[0037] The base fiber of this embodiment is polyester long fiber, namely polyester POY colored long fiber.

[0038] The product made from the base fiber is fluorine-free, environmentally friendly and splash-proof high-elastic polyester.

[0039] Specifically, such as figure 1 As shown, the preparation method of the fluorine-free environmentally friendly splash-proof high elastic polyester of the present embodiment comprises the following steps:

[0040] Using the "two-for-one twisting" high-elasticity process, when polyester POY colored long fibers are in the texturing machine, the temperature of the upper heating box is 160-200 ° C, which is 5-20% higher than the conventional process; the false twister "D / Y ratio ” is 1.6-1.9, which is 5-20% higher than the conventional process; the fiber is two strands, one in the S direction and the other in the Z direction, which are combined and directly wound after passing through their respective false twisters; for example, the textur...

Embodiment 2

[0047] The base fiber of this embodiment is polyamide long fiber, that is, polyamide POY colored long fiber.

[0048] The product made from the base fiber is fluorine-free, environmentally friendly, splash-proof and high-elastic nylon.

[0049] Specifically, such as figure 1 As shown, the preparation method of the fluorine-free environmentally friendly splash-proof high-elastic nylon of the present embodiment includes the following steps:

[0050] Using the "network" high-elasticity process, when nylon POY colored long fibers are texturized by the texturing machine, the temperature of the upper heating box is 180-220 ° C, which is 5-20% higher than the conventional process; the "D / Y ratio" of the false twister is 1.8-2.2, 5-20% higher than the conventional process; the fiber is two strands, one in the S direction and the other in the Z direction. It is 1.3 atmospheres; in addition, the air pressure of the network nozzle can be selected according to actual needs between 1.1-2...

Embodiment 3

[0057] The base fiber of this embodiment is made of polypropylene long fiber, that is, polypropylene POY colored long fiber.

[0058] The product made from the base fiber is fluorine-free, environmentally friendly, splash-proof and high-elastic polypropylene fiber.

[0059] Specifically, such as figure 1 As shown, the preparation method of the fluorine-free environmentally friendly splash-proof high-elastic polypropylene fiber of this embodiment includes the following steps:

[0060] Adopt "two-for-one twisting" high-elasticity technology, when the polypropylene POY colored long fiber is textured in the texturing machine, the temperature of the upper heating box is 150-170℃, which is 5-20% higher than the conventional technology; the "D / Y ratio" of the false twister 1.6-1.8, which is 5-20% higher than the conventional process; the fiber is two strands, one in the S direction and the other in the Z direction, which are combined and directly wound after passing through their re...

Abstract

The invention belongs to the technical field of textile industry, and in particular relates to a plasma-modified fluorine-free environmentally-friendly anti-splash high elastic fiber and a preparationmethod and application thereof. The preparation method comprises the step of successively carrying out mechanical high-elasticity, plasma-modified anti-splash treatment, high-temperature oven bakingand winding molding for a matrix fiber. The preparation method is green, environmentally friendly and pollution-free, has a simple process, and reduces the production cost and labor cost. The fluorine-free environmentally-friendly anti-splash high elastic fiber can be woven directly on the machine into anti-splash flying woven uppers, and can be directly made into fluorine-free environmentally-friendly anti-splash shoes. After being tested, the fluorine-free environmentally-friendly anti-splash high elastic fiber can reach the highest level 5 in a spray performance before washing and after washing, and meets the requirement of the anti-splash performance of flying woven shoes.

Description

technical field [0001] The invention belongs to the technical field of the textile industry, and in particular relates to a plasma-modified fluorine-free, environment-friendly and anti-splash high-elastic fiber as well as a preparation method and application thereof. Background technique [0002] At present, the "fluorine-free environmental protection and splash-proof" finishing agents often used in textiles on the market contain fluorine, especially C8 organic fluorine chemicals containing PFOS (perfluorooctane sulfonic acid) and PFOA (perfluorooctanoic acid), which are harmful to the human body. Bioaccumulation, varying degrees of toxicity, persistence and potential hazards. Therefore, the use of PFOS and PFOA is strictly restricted. Although fluorine-free waterproofing agents (only splash-proof, not oil-proof and not anti-fouling) can't achieve the effect of fluorine-containing waterproofing agents, but based on the improvement of environmental protection awareness, only...
