Waterproof moisture-permeable composite fabric with gradient pore size distribution
The invention discloses a waterproof moisture-permeable composite fabric with gradient pore size distribution. An A/B/C/D four-layer structure is adopted, a surface layer A is taken as an external strength layer of the composite fabric, a textile fabric mainly made of polyester or nylon chemical fibers with breaking strength larger than 200 N is adopted, and the maximum pore size ranges from 40 micrometers to 200 micrometers; the B layer adopts PP melt-blown cloth with the maximum aperture of 10-40 microns as a supporting layer of the C layer microporous membrane with the nanoscale aperture; the layer C is a waterproof and moisture permeable functional film layer serving as a core and is made of a biaxially oriented PE microporous film material manufactured by a thermally induced phase separation method, wherein the average pore size of the biaxially oriented PE microporous film material is 50-200 nanometers, the air permeability Gurley value of the biaxially oriented PE microporous film material is 10-90s/100cc, and the latent heat of fusion of the biaxially oriented PE microporous film material is 160-250J/g; the inner layer D adopts spun-bonded non-woven fabric or polyester taffeta or oxford fabric and other textile lining as a wear-resistant protective layer of the layer C; interfaces among the layers are subjected to hot-pressing composite connection by adopting a thermoplastic rubber type or EVA (Ethylene Vinyl Acetate)-based or a combined hot melt adhesive mesh porous material of the thermoplastic rubber type or the EVA-based or the thermoplastic rubber type or the EVA-based or the combined hot melt adhesive mesh porous material with the gram weight of 4-12g/m < 2 >, the moisture permeability of the composite fabric is greater than 8000g/(m < 2 > * 24h), and the hydrostatic pressure resistance is greater than 30KPa.
具有梯度孔径分布的防水透湿复合面料，采用A/B/C/D四层结构，表层A作为复合面料的外部强度层，采用断裂强力大于200牛的涤纶或尼龙化纤为主的纺织面料，最大孔径介于40‑200微米；B层采用最大孔径介于10‑40微米的PP熔喷布作为纳米级孔径C层微多孔膜的支撑层；C层作为核心的防水透湿功能膜层，采用平均孔径介于50‑200纳米，透气度Gurley值介于10‑90s/100cc，熔融潜热介于160‑250J/g的热致相分离法制造的双向拉伸PE微多孔膜材料；内部的D层采用纺粘无纺布或涤塔夫或牛津布等纺织里布作为C层的耐磨保护层；各层之间的界面采用克重介于4‑12克每平米的热塑性橡胶型或EVA基或二者的组合热熔胶网状多孔材料进行热压复合连接，复合面料的透湿率大于8000g/(m2*24h)，耐静水压大于30KPa。
