Breathable layered flexible materials, methods and uses thereof

The present disclosure relates to a breathable layered flexible material comprising at least one polyvinyl chloride (PVC) porous layer or a plurality of PVC porous layers; and a support layer; wherein pores of the PVC porous layer or the plurality of PVC porous layers are obtained by water evaporation of the water-in-oil PVC emulsion; and wherein the pores extend from the PVC layer to the support layer to provide air permeability of the material. The present disclosure also relates to a method for preparing the breathable layered flexible material. Decoration, in particular automotive trim, comprising the breathable layered flexible material is also disclosed. 本公开涉及透气层状柔性材料，包括至少一个聚氯乙烯(PVC)多孔层或多个PVC多孔层；和支撑层；其中，所述PVC多孔层或多个PVC多孔层的孔通过油包水PVC乳液的水蒸发获得；并且其中，孔从PVC层延伸到支撑层以提供材料透气性。本公开还涉及用于制备所述透气层状柔性材料的方法。本发明还公开了包含透气层状柔性材料的装饰，特别是汽车装饰。
