Problems solved by technology

And there is no report about coating tourmaline on the surface of activated carbon fibers at present.
The reason is that the particle size of tourmaline powder is large, it cannot be firmly combined with the surface of the fiber, and it is easy to peel off.
And because their preparation method does not go through the roasting process, various antibacterial agents and negative ion releasing materials are not firmly combined with carbon fibers, and they are easy to fall off, so they cannot be used in air or water for a long time

Abstract

The present invention relates to a negative ion anti-bacterial hollow carbon fibre and its preparation method. It includes (by weight ratio) 5-13 portions of tourmaline, 0.6-4 portions of Ag anti-bactrial agent, 15-25 portions of Ti (OC5H11)4 and 100 portions of hollow active carbon. Its preparation method includes the following steps: using hollow active carbon as carrier, adopting vacuum repeated impregnation process to make the micro-size tourmaline powder be fed into central pore of hollow active carbon fibre, and utilizing the combination of vacuum repeated impregnation and sol-gel to make the surface of hollow active carbon fibre be coated with nano-size silver series anti-bacterial agent and nano-size TiO2 series anti-bacterial agent. The number of negative ions released by the invented hollow active carbon fibre can be up to 2200-2250 / cu cm. For Escherichia coli the diameter the diameter of its bacteriostatic ring can be up to 22 mm, and for staphylococcus aureus the diameter of its bacteriostatic ring can be up to 21.5 mm.

Description

technical field [0001] The invention relates to an anion antibacterial hollow activated carbon fiber, and also relates to a preparation method of the anion antibacterial hollow activated carbon fiber. Background technique [0002] The document "Chinese Patent N002111545.1" discloses a silver-loaded tourmaline multifunctional fiber and its manufacturing method, which is made of silver-loaded tourmaline and viscose fiber. The fiber has the advantages of emitting far infrared, releasing negative ions, generating bioelectricity, antibacterial, deodorizing and deodorizing. [0003] The document "Chinese patent NO03147863.8" discloses an antibacterial activated carbon fiber and its preparation method. Activated carbon fibers are immersed in a solution containing at least one metal ion Ag#+[+], Cu#+[2+], Zn#+[2+], and the activated carbon fibers are covered with silver through adsorption and chemical reaction. ions, copper ions and zinc ions, and then dried, it has a good effect ...
