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 the human body. Sexual problems, while the latter is prone to wool or broken ends, it is difficult to obtain high-quality fabric feel; again, there is a patent report (Chinese Patent Application No. 03131864.9) that the antibacterial agent accounts for 2% of the total weight in the nano antibacterial superfine fiber material. 40%, the application of a large number of valuable antibacterial agents and the preparation method of electrospinning are not conducive to industrial production; finally, most of the existing nano-antibacterial microfibers rely on imports, and the domestic technology content is low, and it is urgent to improve industrialization. technical content

preparation example Construction

[0027] In the preparation process of the product of the present invention, the raw materials and methods in the stripping process of the fiber material obtained by the action of the twin-screw extruder all belong to those skilled in the art and the production personnel. Therefore, in the specific embodiment In this part, the content is omitted. The diameter of the nano-antibacterial superfine fiber has nothing to do with the raw materials used in alkali hydrolysis, the concentration of the solution and the pH value, but only the increase in the number of peeling times.

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

Embodiment 1

[0030] In a chemical fiber factory, 200 kg of nylon 6, 200 kg of polyethylene terephthalate and 1 kg of silver-containing nanoporous zeolite ultrafine particles were mixed, and the silver-containing nanoporous zeolite ultrafine particles The size is 100 nanometers, melted at high temperature, and 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.

Embodiment 2

[0032]In a chemical fiber factory, 10 kg of nylon 6, 10 kg of butanediol terephthalate and 0.1 kg of ultrafine particles of nanoporous zeolite containing titanium dioxide were mixed in formic acid, and the nanoporous zeolite containing titanium dioxide The size of the ultra-fine particles is 100 nanometers, dispersed evenly, connected to the injection head through a syringe pump and a catheter, the injection head is connected to a high-voltage positive electric field, the copper grid is grounded, the distance between the injection head and the copper grid is controlled at about 10cm, and the solution flow rate is 300ml / h, the voltage is 10kv, and electrospinning is carried out to obtain a kind of nylon 6 / butylene terephthalate nano antibacterial superfine fiber containing nano antibacterial particles, and 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...
