Abstract: This paper starts from the actual functional requirements for water rescue clothing of our country's fire rescue front-line 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 7 000 g/（m2·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.
