Waterproof-breathable multilayer structure

Abstract

The invention relates to a multilayer structure comprising a textile layer comprising at least one polymer chosen from a polyamide and a copolymer containing polyamide blocks and polyether blocks, and combinations thereof; and a film comprising at least one copolymer containing polyamide blocks and polyether blocks, the polyether blocks comprising polyethylene glycol blocks, the polyethylene glycol blocks representing at least 40% by mass relative to the mass of the film; in which the film adheres to the textile layer via a copolyamide. The invention also relates to a process for manufacturing said multilayer structure, to a process for recycling said multilayer structure and also to an article comprising said multilayer structure.
