The application discloses a medical natural antibacterial and antiviral mildew-proof wet non-woven fabric and a preparation method and application thereof, and belongs to the technical field of medical polymer materials and textiles. The non-woven fabric is prepared from the following raw materials: polyethylene terephthalate long fibers, polyethylene terephthalate short fibers, vinylon fibers and natural antibacterial and antiviral ultraviolet slow-release glue solution. The non-woven fabric is endowed with natural and non-toxic antibacterial and antiviral effects by using the extract of Chinese herbal medicine effective components. Meanwhile, the mechanical properties and the antibacterial and antiviral capacity of the non-woven fabric can be effectively improved by adding nano materials with far infrared function after surface modification to prepare high-efficiency natural antibacterial and antiviral ultraviolet slow-release microcapsule glue solution. The method improves the added value and application field of the wet non-woven fabric and is convenient for large-scale processing and production. The prepared wet non-woven fabric has excellent performance indexes, good air permeability and an antibacterial and antiviral efficiency of 99.99%.

This invention provides non-fired tiles and a method for manufacturing non-fired tiles that make it possible to reduce carbon dioxide emissions. [Solution] A fired tile containing 1 to 7 parts by weight of Portland cement (1), 18 to 58 parts by weight of blast furnace slag (2), 57 to 77 parts by weight of a carbon dioxide adsorbent (3) which is a powder containing calcium carbonate derived from calcium compounds that chemically adsorbs carbon dioxide, and 0.1 to 5 parts by weight of organic fiber (4) which is a synthetic fiber called vinylon RMS, is manufactured by sequentially carrying out a mixing process, a molding process, a first drying process, a steam curing process, a second drying process, and a coating process.

The invention discloses a skeleton non-woven fabric. The skeleton non-woven fabric at least contains 25-45 wt% of vinylon fibers, 25-45 wt% of polyester fibers and 15-25 wt% of an adhesive. The skeleton non-woven fabric disclosed by the invention has the characteristics of high air permeability and high rigidity and softness, and can be applied to the field of air filtration.
