背景技术
SM无纺布属于复合无纺布，是纺粘无纺布和熔喷无纺布的复合产品，具有强力高、过滤性能好、透气性能好、不含粘合剂、无毒等优点，目前主要用于医疗卫生劳动防护产品如屋顶、手术服、手术帽、防护服、洗手衣、手袋等。
相对于单独使用纺粘无纺布，SM无纺布在屋顶材料中主要作为防滑材料使用时的优点有：表面凹凸不平，防滑效果好，并且添加抗老化母粒，具备抗UV功能，避免长时间阳光照射导致的布面粉化。但是现有的SM无纺布有两种工艺，一种是SM热轧法，该方法加工的材料，其强度高，但是由于过轧机将材料完全融为一体，导致产品的布面光滑，只能靠单纯纺粘轧机轧点起到防滑作用，防滑效果甚微。另一种工艺是将熔喷层喷覆在纺粘层上面，不经过轧机热轧，但由于熔喷铺网过程中迅速结晶，导致熔喷层和纺粘层在结合时不能完全粘合在一起，容易分层，造成后加工过程中，由于两种无纺布材料强力等性能不同，拉伸张力也不一致，高速生产过程中容易出现断布的情况，此外，由于熔喷无纺布的耐磨性差，强度不度，硬挺度不够，导致了SM无纺布的耐磨性，强度和硬挺度较差。
为了解决上述问题，目前最常用的方法为使用热压粘合将两种无纺布粘合到一起,但是该方法会影响制备的SM无纺布的防滑效果,而且不能从根本上解决两种无纺布材料强力等性能不同，拉伸张力也不一致，高速生产过程中容易出现断布的问题，也不能解决SM无纺布的耐磨性，强度和硬挺度较差的问题。
