摘要： Filter media and filters are provided that include at least two layers and a plurality of nanoparticles dispersed in depth within at least one of the layers. A gas filter comprises a first layer of fibers, a second layer of fibers bonded to the first layer and a plurality of nanoparticles incorporated into the first layer. The nanoparticles increase the overall surface area within the filter, which increases its filtration efficiency and allows for the capture of submicron contaminants without significantly compromising other factors, such as pressure drop (i.e., air flow) through the filter. In addition, the filters disclosed herein are capable of withstanding rigorous conditioning, which allows the filter to achieve the same level of filtration performance throughout the lifetime of the filter. Systems, devices and methods are also provided for manufacturing such filters.

摘要： An air-cleaning filter includes a non-woven fabric for dust collection and a non-woven fabric for deodorization having activated carbon particles combined therewith. By adjusting the particle diameter and content of the activated carbon particles and laminating with a non-woven fabric coated with an absorber for other gases, a dust collecting function and a deodorizing function can be imparted at the same time while also creating a structure with a low differential pressure.

摘要： An absorption and retention system for vehicle leaks consists of a top absorbent pad received by a bottom layer, the two being fused together. The combination of top pad and bottom layer are geometrically configured to be removably attached by wires to the undercarriage of a vehicle and to be positioned for receiving leaks from the vehicle and being of a geometric configuration to avoid interference with any operative portions of the vehicle such as wheels or the like. The pad is adaptable for receiving any of numerous liquids, including lubricants, hydraulic fluids, coolants and the like. The top pad may be of absorbent polypropylene and the bottom film of a suitable flexible and impermeable plastic or spunbond polypropylene fabric. A mechanic pad facilitates implementation of the absorption and retention system.

摘要： An antibacterial and antiviral degradable mask and a manufacturing method thereof are provided. From outside to inside, the mask sequentially comprises a surface layer (1), a core layer (2), and an inner layer (3) that contacts the face; the surface layer (1) is made of an antibacterial and antiviral cellulose spunlace non-woven fabric; the core layer (2) is made of a polypropylene melt-blown non-woven fabric; the inner layer (3) is made of a polypropylene spunbond non-woven fabric or a degradable natural cotton fabric. The mask can have both antibacterial and antiviral functions; moreover, the material is degradable, and thus, environmental pollution pressure caused by non-degradable petroleum-based fiber materials such as polypropylene can be effectively relieved.
