Nanofiber-based biomedical non-woven fabric and preparation method thereof

Abstract

The invention discloses a nanofiber-based biomedical non-woven fabric and a preparation method thereof. Firstly, phase-change temperature-adjusting microcapsules are added into nuclear layer liquid offirst fibers, a large number of hydrophilic groups are introduced into the nuclear layer liquid to prepare fibers A with super-hydrophilic performance, and alkali liquor is used for preparing multiple holes in the surfaces of the fibers A, so that the binding force of the fibers A and antibacterial capsules is increased; and a spinning solution is modified through an electrochemical method, modified ceramic with anti-radiation and anti-bacterial capacity is added, second fibers with super-hydrophobic performance are obtained, and a first non-woven fabric and a second non-woven fabric are bonded through a bonding agent to obtain the biomedical non-woven fabric which has the phase change temperature adjustment capacity, the moisture absorption capacity, the anti-bacterial capacity, the blood repelling capacity and the anti-radiation capacity, while the wearing comfort of medical staff is improved, invasion of microorganisms and pathogens can be effectively resisted, and high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to nanofiber-based biomedical nonwoven fabrics and a preparation method thereof. Background technique [0002] Biomedical non-woven fabrics refer to materials used to diagnose, treat, repair or replace damaged tissues and organs of living organisms or enhance their functions, mainly including surgical gowns, protective clothing, sterile cloth bags, masks, diapers, etc. . [0003] The current protective clothing on the market needs to have a good microbial isolation function, which leads to the fact that the protective clothing does not have the ability to absorb moisture and breathe. When wearing traditional protective clothing, medical staff tend to feel stuffy and uncomfortable, and the sweat secreted cannot be discharged in time. Bacteria are also very easy to breed in protective clothing; at the same time, there are usually some instruments in the hospital that need to...

AI Technical Summary

Problems solved by technology

[0003] The current protective clothing on the market needs to have a good microbial isolation function, which leads to the fact that the protective clothing does not have the ability to absorb moisture and breathe. When wearing traditional protective clothing, medical staff tend to feel stuffy and uncomfortable, and the sweat secreted cannot be discharged in time. Bacteria are also very easy to breed in protective clothing; at the same time, there are usually some instruments in the hospital that need to use radiation to examine the body. Occasionally irradiating the human body will not have much impact on the human body, but medical staff need to stay in this environment for a long time Ionizing radiation can easily cause harm to the human body, cause cell mutation and white blood cell death, and cause cancer, leukemia and other human terminal diseases. However, the current radiation protection clothing on the market is expensive, difficult to prepare, and the popularity rate is not high. Therefore, people urgently need a biomedical non-woven fabric with simple principle, good radiation protection effect, certain antibacterial and moisture absorption ability, and good blood repelling effect to prepare medical protective clothing.
