wherein, the PTFE nanofiber has the high-efficiency low-resistance filtering function, and the polycaprolactone has good biocompatibility and biodegradability. The composite film can be manufactured by the following steps:
firstly, PTFE dispersion resin and extrusion aid are mixed according to a certain proportion, and PTFE sheet is prepared through the procedures of extrusion, calendaring, drying and the like;
then, the PTFE sheet is biaxially stretched at a certain temperature and speed to form a network structure formed by connecting micro fibers, namely a PTFE nano film;
then, melting PCL particles at a certain temperature, and coating the PCL particles on two sides of the PTFE nano film in a spraying or dipping mode to form a PCL coating;
finally, the coated PTFE nano-film is subjected to hot pressing or hot air curing and other procedures, so that the PCL coating and the PTFE nano-film are firmly combined, and the PTFE composite film 15 is obtained.
When the double-layer composite nano antibacterial non-woven fabric medical protective clothing is used, a user pulls the zipper 10 open, wears the medical protective clothing on a body, pulls the zipper 10 closed, and bonds the second wool surface magic tape fixing band 12 and the second hook surface magic tape movable band 13, so that the strip-shaped baffle cloth 11 shields the zipper 10, and then bonds the first wool surface magic tape fixing band 5 and the first hook surface magic tape movable band 6 on the two sleeves 2, thereby completing the wearing of the medical protective clothing, when the user breathes, the external air enters the hood 7 from the ventilation tube 90, bacteria can be effectively prevented from being inhaled under the action of the pre-filter layer 91, the high-efficiency filter layer 92 and the active carbon filter layer 93, and good ventilation property and comfort are maintained, and because the upper clothing 1, the sleeves 2, the trousers 3, the foot sleeves 4 and the hood 7 are all made of the double-layer composite nano antibacterial non-woven fabric, and the comfort of the medical protective clothing can be improved due to the first plant nano cellulose non-woven fabric 14; the PTFE composite film 15 can effectively isolate bacteria and viruses and prevent cross infection; the second plant nano-cellulose non-woven fabric 16 can enhance the durability and the protectiveness of the medical protective clothing, the waterproof layer 17 is arranged on the inner side of the first plant nano-cellulose non-woven fabric 14, and the wear-resistant layer 18 is arranged on the outer side of the second plant nano-cellulose non-woven fabric 16, so that the medical protective clothing has good antibacterial effect, comfort, skin-friendly property, durability and protectiveness, and is suitable for personal protection.
The foregoing has shown and described the basic principles, principal features and advantages of the utility model.
