Document Type and Number:
WIPO Patent Application WO/2021/237679
Kind Code:
A1
Abstract:
A bacterial cellulose-based air filter screen and a use. The bacterial cellulose-based air filter screen is of a three-layer structure, i.e., a layer of bacterial cellulose-based filter screen is sandwiched between two layers of polymer fiber filter screens; the polymer fiber filter screens are grid filter screens having a uniform size and formed by weaving polymer fibers by means of blended yarns; and the bacterial cellulose-based filter screen is formed by means of in situ synthesis of bacterial cellulose on a non-woven fabric by bacteria by means of fermentation. The bacterial cellulose-based air filter screen has a good particle filtering effect, large formaldehyde adsorption capacity, good antibacterial property, and a good static electricity bearing capability, can be used in manufacturing a window screen, an air conditioner filter screen, an air purification filter screen, and the like, and has a wide range of uses.
