Non-woven fabric and polyurethane composite material and preparation method therefor

The invention provides a non-woven fabric and polyurethane composite material prepared without adhesives and a preparation method therefor. The composite material comprises the following materials: non-woven fabrics and nonporous or porous polyurethane films. The polyurethane films are directly laminated on the non-woven fabrics, and the composite material contains no adhesives. The invention provides a preparation method for the above composite material. The method comprises the following steps: first, a polyurethane solution is cast into films on a base material; then the films and the non-woven fabrics are compounded; the composite material of nonporous or porous polyurethane films and non-woven fabrics is formed through flexible adjustment of compound technologies. The composite material of nonporous polyurethane films and non-woven fabrics can be used in medical supplies of operating coats, towels or the like. The composite material of porous polyurethane films and non-woven fabrics can be used in medica
