Problems solved by technology

[0003] However, through literature search, it is found that there are still many defects in the existing antibacterial fibers: first, the diameter of the existing antibacterial fibers is relatively thick, usually above 3 microns, which limits the ability of the fiber material to filter ultrafine particles and extremely fine particles containing viruses. The application of particles and aerosols, especially in clothing and medicine; secondly, the existing antibacterial fibers mainly adopt the post-treatment method and the original silk improvement method, but the antibacterial and deodorant dissolved by the former may have potential safety hazards and durability to th

Example Embodiment

[0027] In the preparation process of the product of the present invention, the fibrous material is prepared by the action of the twin-screw extruder and the raw materials and methods in the peeling process of the alkali hydrolysis method all belong to the technical content well-known to those skilled in the art and the production personnel. Therefore, in the specific embodiments This part of the content is omitted in the article. The diameter of the nano antibacterial ultrafine fibers has nothing to do with the raw materials used in the alkaline hydrolysis, the concentration of the solution and the pH value, but the increase in the number of peelings.

[0028] The following examples do not limit the twin-screw extruder because although the manufacturers and models of the twin-screw extruders are different, they do not affect the preparation of colored nano-antibacterial ultrafine fibers.

Example Embodiment

[0029] Example 1

[0030] In a chemical fiber factory, 200 kilograms of nylon 6, 200 kilograms of polyethylene terephthalate and 1 kilogram of silver-containing nanoporous zeolite ultrafine particles are mixed, and the silver-containing nanoporous zeolite ultrafine particles are mixed The size is 100 nanometers, melted at high temperature, through the action of a twin-screw extruder, a polyamide / polyester nano antibacterial fiber containing nano antibacterial particles is obtained. After alkali hydrolysis, a nano antibacterial fiber with a diameter of 150 nanometers is obtained. superfine fiber.

Example Embodiment

[0031] Example 2

[0032]In a chemical fiber factory, 10 kilograms of nylon 6, 10 kilograms of butylene terephthalate and 0.1 kilograms of particle size nanoporous zeolite containing titanium dioxide ultrafine particles are mixed in formic acid, which contains titanium dioxide nanoporous zeolite The ultra-fine particles are 100 nanometers in size and uniformly dispersed. They are connected to the jetting head through a syringe pump and a pipe. The jetting head is connected to a high-voltage positive electric field, and the copper mesh is grounded. The distance between the jetting head and the copper mesh is controlled at about 10cm. h, the voltage is 10kv, electrospinning is performed to obtain a nylon 6 / butylene terephthalate nano antibacterial ultrafine fiber containing nano antibacterial particles, the diameter of the fiber is 100 nanometers.

Abstract

The present invention relates to a nano-grade anti-bacterial super-fine fibre material and its production method. In particular, it relates to a method for producing nano-grade anti-bacterial super-fine fibre material by adopting melt- spinning process. The invented nano-grade anti-bacterial super-fine fibre material is formed from (by wt%) 98%-99.9% of high-molecular super-fine fibre and 0.1%-2% of nano-grade anti-bacterial agent. Besides, said invention also provides the concrete steps of its production method.

Description

Technical field: [0001] The invention relates to a nano antibacterial ultrafine fiber material and a production method, in particular to a nano antibacterial ultrafine fiber material produced by a melt spinning method. Background technique: [0002] Various microorganisms live in the environment of human life. Various textiles such as towels, quilts, underwear, toys, etc. used in daily life are suitable places for the growth and reproduction of microorganisms, which have a huge impact on human health and even release Disgusting odor affects environmental sanitation; with the rapid development of modern fiber technology and the improvement of living standards, people put forward higher requirements for the functions of fibers used in daily life, and the proportion of high-tech fibers will increase Increase, antibacterial textiles will be widely used in the fields of information industry, biomedical engineering, energy engineering, environmental protection engineering, militar...
