Abstract: Nonwoven manufacturing technology combined with finishing technics such as specific impregnation were used to investigate effects of web-forming,consolidation method and water-repellent finishing etc on environmental friendly bast fiber mulch film,and bast fiber such as ramie and jute were major material for trial manufacture.The results showed that the bast fiber mulch film manufactured by using web-forming technic combining carding with air-lay,chemical consolidation method taking use of acrylate or vinyl acetate latex as consolidation agent,product surface dipped by waterproof agent(organic fluorine) has surface density of 30-50 g/m~2,tensile strength of 629-1 532 N·m,bursting strength of 81-203 N,tearing strength of 56-82 N and permeability coefficient of 7.79×10~-4-1.76×10~-3.Its mechanical property indexes can meet application requirements.
