Breathable waterproof cloth and manufacturing method thereof

The invention discloses breathable waterproof cloth and a manufacturing method thereof. The breathable waterproof cloth comprises a base material, an electrospinning film and a melt-blown adhesive film. The electrospun membrane is disposed on the substrate and includes a plurality of nanofibers, and the average fiber fineness of the nanofibers is 100 nm to 800 nm. The melt-blown adhesive film is arranged between the base material and the electrospinning film, the melt-blown adhesive film comprises a plurality of melt-blown fibers, and the average fiber fineness of the melt-blown fibers is 800 nanometers to 20 micrometers. The breathable waterproof cloth prepared by the manufacturing method disclosed by the invention has high breathability, high waterproofness and high interlayer strength. 一种透气防水布及其制造方法，透气防水布包括基材、电纺膜及熔喷粘胶膜。电纺膜配置于基材上并包括多条纳米纤维，且纳米纤维的平均纤维细度为100纳米至800纳米。熔喷粘胶膜配置于基材与电纺膜间，熔喷粘胶膜包括多条熔喷纤维，且熔喷纤维的平均纤维细度为800纳米至20微米。以本揭露的制造方法制备而成的透气防水布兼具高透气性、高防水性及高层间强度。
