The Advantages Of Antibacterial Fiber Are Obviously Favored.

The rapid development of chemical fiber has provided a very wide field for fiber modification, so people began to turn the perspective of antibacterial and deodorant treatment to fiber modification to obtain antibacterial and odorless textiles.

This method is highly technical and difficult, involving a wide range of engineering fields, especially for the requirements of antibacterial and deodorant, but because of its obvious advantages, it is well received by customers.

Antibacterial and deodorant fibers are developed on the technology of antibacterial and deodorizing post-treatment.

In the world, there has been a method of producing durable antibacterial and deodorant fibers by means of polymer modification and blending modification of chemical fibers since 80s.

Compared with the antibacterial and deodorizing post-treatment technology, the antibacterial and deodorant fiber has good deodorizing effect and durability, and the fiber does not adhere to the resin. The fabric has good handle, simple process, and no need for finishing, and the cost is low.

Although the antibacterial and deodorizing finishing is easy to process, the antibacterial and deodorizing effect is not ideal. After dozens of washing, the antibacterial and deodorizing effect of the fabric is reduced, and it is difficult to meet the requirements of consumers.

(1) grafting antibacterial fiber groups onto fibers by chemical modification.

For example, the Japanese silkworm dyed dyeing company used the dyeing method to form the coordination bond between the CN base and the CugSs of the acrylonitrile fiber, and produced the shengdun SS N fiber, which is both antibacterial and deodorant, and can also conduct electricity and prevent static electricity.

(2) in

In the process,

Blending with acrylonitrile or polyamide and other polymers.

This is the main way to develop antibacterial and deodorant fibers.

(3) use physical modification to immerse the antibacterial agent into the deeper part of the fiber surface.

When the melt is spun, the antibacterial and deodorant is added to the spinning agent and cooled with draft. When the shrinkage fiber is melted, the antibacterial fiber deodorant is wrapped in the surface layer.

Immersing the gel fiber in wet spinning into the antibacterial and deodorant solution, sealing the antibacterial and deodorant solution into the interior.

The development of multi microporous fibers is also conducive to the penetration of antibacterial and deodorant.

(4) compound spinning technology.

If the antibacterial deodorant is added to the fiber cortex or a part of the composite fiber.

The composite antibacterial and deodorant fiber with island structure and mosaic structure is being developed.

The antibacterial and deodorant fiber products are the best in Japan, followed by the European and American countries. Our country has also made research and development in this area in the past ten years, including the Shanghai synthetic fiber research institute, Jiangsu Textile Research Institute, Shanghai Petrochemical experimental plant and so on.
