干式水域救援服用复合织物的性能研究

Research on properties of composite fabric for dry water rescue suit

从我国消防救援一线对水域救援服的实际功能需求出发,通过层压加工试制具有防水透气性能的复合织物,选取市售干式水域救援服用的典型外层面料及膜材料的复合面料,通过防水性、透湿性、力学性能等性能测试,对几种面料进行实用性能对比,研发综合性能优异的干式水域救援服用防水透气复合面料,并以其试制干式水域救援服样衣对其整体防水抗浸性能进行验证。结果表明,本研究试制的高强纤维织物/PTFE膜复合织物的综合性能最优,其耐静水压数值为100 kPa以上,透湿率达7000 g/(m^(2)·d),经纬向撕破强力分别为241,171 N,防水性、透气舒适性、耐用性俱佳,更加适应我国水域救援的实际需求,具有良好的应用前景。

This paper starts from the actual functional requirements for water rescue clothing of our country's fire rescue frontline team.Composite fabrics with waterproof and moisture permeability were prepared through laminating processing.The typical outer layer fabrics and membrane materials of commercial dry water rescue suit were selected.The practical performance of several fabrics was compared through performance tests such as hydrostatic resistance,moisture permeability,and mechanical properties,and a waterproof and moisture permeable composite fabric for dry water rescue suit with excellent comprehensive performance was developed.The overall waterproof and anti-soaking performance of the trial-made dry water rescue suit with self-produced fabrics was verified.The results show that the comprehensive performance of the high-strength fiber fabric/PTFE membrane composite fabrics in this study is the best,which has the hydrostatic pressure resistance value of more than 100 kPa,the moisture permeability of about 7000 g/(m^(2)·d)and warp and weft tear strengths of 241 N and 171 N respectively.With excellent waterproofness,moisture permeability,comfort and durability,it is more suitable for the actual needs of water rescue in our country and has a good application prospect.
