环保型麻地膜的试制

 将非织造布制造工艺与特有的浸渍等后整理工艺相结合,以苎麻、黄麻等麻类纤维为主要试制原料,研究成网方法、固结方法、拒水整理等对环保型麻地膜的影响。结果表明,采用梳理成网与气流成网相结合的成网工艺、使用丙烯酸脂胶乳或醋酸乙烯胶乳为固结剂的化学固结方法,产品表面浸渍有机氟防水剂等组合工艺,试制的麻地膜产品面密度为30~50 g/m2、抗拉强力为629~1 532 N.m、顶破强力为81~203 N、撕破强力为56~82 N、渗透系数为7.79×10-4~1.76×10-3,产品力学性能指标满足使用要求。

Trial manufacturing of environmental friendly bast fiber mulch film

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.
