Abstract

The invention relates to a preparation method of an anti-static high-strength medical fabric and belongs to the technical field of preparation of medical supplies. The preparation method comprises thefollowing operation steps: firstly calcining a bamboo chip with acid and alkali to prepare a calcined product, then reacting graphite and potassium ferrate in a sulfuric acid solution, reacting withcopper sulfate and ferric trichloride, reducing with hydrogen peroxide to prepare a reaction solid, finally putting spandex, terylene, the calcined product and the reaction solid in a spinning machinefor spinning and drying to prepare the anti-static high-strength medical fabric; carbon fibers have good electrical conductivity and can effectively prevent the fabric from generating static electricity during the friction process, so that the electrical conductivity of graphene fibers is enhanced; as bamboo fibers are large in pipe diameter, the prepared carbon fibers have relatively large porosity, the air permeability of the fabric is enchanted; nano-graphene enables the graphene fibers to have good mechanical properties; meanwhile, copper ions and iron ions are introduced; in combinationwith metal ions, the mechanical properties of the graphene are further enhanced; therefore, the application prospect is wide.

Description

technical field [0001] The invention relates to a method for preparing an antistatic high-strength medical fabric, which belongs to the technical field of medical product preparation. Background technique [0002] Medical workers are people who are in direct contact with bacteria and viruses. There are various germs in their working environment, especially doctors who perform infusion, trauma treatment and surgical operations. They often come into contact with patients' body fluids or blood. , the probability of infection is very high, and their own health is often threatened, so they have to wear thick protective clothing to achieve the protective effect. [0003] According to different processing techniques, medical textiles can be roughly divided into: ordinary textiles, non-woven fabrics, knitwear, and special fabrics (such as fabrics with good air permeability such as perforated fabrics, which can be used for medical products such as skin patches). In addition to tradi...
