A copper-based metal-organic framework antibacterial fiber and its preparation method

Abstract

The invention discloses antibacterial fibers with a copper-based metal organic framework. The antibacterial fibers with the copper-based metal organic framework are prepared from 80-99.9% of polyester, 0.1-20% of a copper-based metal organic framework material and an antibacterial agent, wherein the antibacterial agent is at least one of a quaternary ammonium salt antibacterial agent of vitamin C at the mass percent concentration of 5-20% and a halamine antibacterial agent of vitamin C at the mass percent concentration of 5-20%. A method for preparing the antibacterial fibers comprises the steps that the copper-based metal organic framework material and polyester are subjected to melt spinning with a spinning machine, and copper-based metal organic framework and polyester composite fibers are obtained; the copper-based metal organic framework and polyester composite fibers are steeped into the antibacterial agent, then rinsing and drying are carried out, and the antibacterial fibers with the copper-based metal organic framework are obtained. The obtained antibacterial fibers with the copper-based metal organic framework have good antibacterial performance and are simple in preparing method.

Description

technical field [0001] The invention relates to the field of functional textile functional materials, in particular to a copper-based metal-organic framework antibacterial fiber and a preparation method thereof. Background technique [0002] Copper-based metal-organic framework is the abbreviation of copper-organic framework material. It refers to the porous material that forms a periodic network through self-assembly of copper ions and organic ligands. It has high porosity, large specific surface area, regular channels, and controllable particle size. Advantages, widely used in medical treatment, adsorption, catalysis, energy storage and other fields. Antibacterial fiber refers to a type of fiber with antibacterial function, which is widely used in medical and health, civilian and military textiles and other fields.

Problems solved by technology

In the present invention, organosilicon quaternary ammonium salt and cationic silicon-containing surfactant are used in the fabric, so that the fabric has good softness, resilience, smoothness and obvious antistatic effect, and the organosilicon quaternary ammonium salt and oxidation The joint use of copper makes the fiber obtained by using copper oxide alone have better repellency and antibacterial properties, but the antibacterial fiber produced by using copper oxide as raw material has higher requirements for wastewater treatment in the production process, which increases the cost

Chinese invention patent (publication number 101148785B, date of publication is March 26, 2008), including the steps of (1) adding comfrey and drug transdermal absorbent to the spinning stock solution containing polyacrylonitrile, (2) spinning stock solution The comfrey medicinal polyacrylonitrile fiber for preventing and treating skin diseases is made by spinning process. This invention has the effect of preventing and treating skin diseases, but its process adopts wet process, the process flow is complicated, and the production cost is high
