Abstract

The invention relates to a method for preparing activated carbon fiber medical dressing. The method specifically comprises the following steps: (1) carrying out pretreatments on a clean raw material fiber, such as deoiling, roughening and activating, and cleaning the clean raw material fiber; (2) chemically silvering the fiber, and supplementing related consumed functional components in the plating solution after the plating operation; (3) washing, dewatering and drying the silver-loaded fiber; (4) pre-treating, carbonizing and activating the silver-loaded fiber. The method is simple in process and principle, the used chemical silvering solution is stable and is suitable for mass production, and granules in the prepared silver-loaded carbon fiber material are firm in binding force with the matrix, moderate in mechanical strength, excellent in antibacterial ability and continuous in stability, so that the silver-loaded carbon fiber material has a broad application prospect in the healthcare industry.

Description

technical field [0001] The invention relates to a preparation method of an activated carbon fiber composite material, in particular to a preparation method of a continuous antibacterial carbon fiber dressing. Background technique [0002] Activated carbon fiber is a new type of high-efficiency adsorbent developed in the 1960s and 1970s. It has the advantages of large specific surface area, rich micropores, small pore size and narrow distribution, large adsorption capacity, and fast adsorption speed. It is widely used in environmental protection and medical treatment. Health and other aspects have broad application prospects. [0003] In the field of water purification and medical sanitation, activated carbon fiber mainly exerts its advantages of excellent filtration and purification, adsorption of microorganisms and absorption of exudate. However, the good times don’t last long. This is because as time goes by, bacteria can easily grow on the surface of carbon fiber, causin...
