PVDF/PVDF混纺纳米纤维防水透湿膜的开发
Preparation of PVDF/PVDF nanofibrous blend as waterproof and breathable membrane
摘要
Abstract
The bico-blended PVDF①/PVDF②nanofibrous membrane was prepared by multineedle electrospinning tech-nology, and the properties such as surface morphology, mechanical strength, waterproof and moisture permeabili-ty were examined to decide the optimum calendering temperature. Thereafter, the bico-blended electrospun membrane was laminated with hydrophobic fabric using Co-PA as thermal binder to prepare breathable fabric, and the properties of which including peeling strength, waterproof and moisture permeability were comparatively studied with PTFE membrane based breathable fabric. The results show that as calendering temperature 135℃, pressure 0.3 kPa and calendering time 1 s, the tensile strength of bico-blended PVDF①/PVDF②nanofibrous membrane calendered is 24.22 MPa, hydrostatic pressure 3 324 mmH2O, moisture permeability is around 10 000 g/(m2·24 h). The compound fabric was prepared by calendering bico-blended PVDF①/PVDF②nanofi-brous membrane, Co-PA thermal binder and the hydrophobic fabric at 135℃and 0.3 kPa for 15 s, its peeling strength(12.28 N/(2.5 cm)) and moisture permeability(5 202 g/(m2·24 h)) were superior to these of PTFE compound fabric, hydrostatic pressure(10 130 mmH2O) was below PTFE compound fabric but can still meet the requirements of commercial use.关键词
