Medical Knowledge: The Key Technology Of Medical Protective Clothing Production, Do You Know?

Cheng Fei, general manager of Shanxi Bing Juan Industrial (Group) Co., Ltd.: medical protective clothing is used as a class of chemical protective clothing, mainly used for medical staff to wear. It not only needs to discharge moisture, breathe freely and wear freely, but also enables medical personnel to avoid infection of viruses, bacteria and other pollutants in the process of diagnosis and treatment, to resist water, alcohol and oil intrusion, and to effectively resist static electricity. And even prevent dust from entering.

First of all, materials should be used to meet the requirements of "three rejecting one resistance" (i.e. water repellency, blood refusal, alcohol refusal and antistatic). This composite material can be made of different materials, such as polyethylene / polypropylene spun adhesive nonwoven fabric, compounded with breathable microporous membrane or other nonwoven fabrics, or combined with spunlaced nonwoven fabric and breathable microporous membrane, or spunlaced nonwovens with wooden paddles.

At present, the non-woven materials used in several medical protective clothing sold and developed in the domestic market are mainly polypropylene spunbonded fabric, Spunlaced fabric made of polyester fiber and wood pulp, polypropylene spunbonded melt blown spunbonded nonwoven fabric, namely SMS or SMMS, high polymer coated fabric, polyethylene breathable film / nonwoven composite cloth.

"Common medical protective clothing is usually connected by hats, tops and trousers. In order to facilitate the wear and tear, and make the bonding more close, the closed door design is usually used in the design, that is, the internal zipper is closed, the external gluing of the plaid is done, and the zipper and the Velcro are pressed through the flat seam. Then, it is made by cutting, suturing, tightening and gluing.

In order to enhance the isolation performance and safety of medical protective clothing. After sewing, it is necessary to glue and seal the stitches and pinholes left in the production so as to prevent dust or liquid from entering the needle holes of sewing.
