医疗防护用防水透湿非织造复合材料的制备及性能
Preparation and properties of waterproof and breathable composite nonwovens for medical protection
摘要
Abstract
To further optimize the protective efficacy and wearing comfort of medical protective materials,hydrophobic breathable composite nonwovens have been meticulously engineered.The composite nonwovens,composed of SS surface layer,SMMS middle layer,and SS lining layer,undergoes polymer modification using a ternary antistatic agent and nano silicon dioxide(SiO2),while the backing material underwent modification treatment with polyethylene glycol(PEG),followed by hot-rolling composite to yield samples of waterproof and breathable composite nonwovens.The mechanical properties,moisture comfort performance and medical protective characteristics of the samples were tested.The results show that the fracture strength of the samples is 143.18 N in longitudinal direction and 68.54 N in transverse direction,and the bursting strength is 1 126.75 kPa,which is higher than the GB 19082-2009 standard.The hydrostatic pressure of the sample is 22.82 kPa,the filtration efficiency is 99.82％,the permeability of the sample is 6.89 mm/s,the permeability of the water vapor is 4 637 g/(m2·d),with both high protective characteristics and wet comfort,far superior to the composite breathable film and other similar medical protection products.关键词
