TPU/POE (thermoplastic polyurethane/polyolefin elastomer) elastic non-woven fabric as well as preparation method and application thereof

The invention discloses TPU/POE (thermoplastic polyurethane/polyolefin elastomer) elastic non-woven fabric and a preparation method and application thereof. Continuous filaments are formed through melt extrusion and drafting of a screw, the filaments are laid to form a web, and the non-woven fabric is formed after a fiber web is subjected to self-adhesion and hot rolling reinforcement. The prepared elastic non-woven fabric contains the thermoplastic polyurethane elastomer, the polyolefin elastomer and the compatilizer, the air permeability is increased to 800-1200 mm/s from traditional 270-300 mm/s, the strength CD is 10-60 N/50 mm, the strength MD is 15-90 N/50 mm, the elongation CD is 100-550%, and the elongation MD is 150-600%. The production process is simple, one-step forming is achieved, the strength is high, the elongation rate is large, the range is wide, the requirements of different fields are met, and the high-end hygienic material can be applied to pull-ups, menstrual period pants and other high-e
