The present application relates to an artificial leather and a manufacturing method therefor. The artificial leather comprises a substrate layer; a polyolefin elastomer composite layer, and a polyurethane resin solution layer, wherein the polyolefin elastomer composite layer is provided on a surface of the substrate layer, and the polyolefin elastomer composite layer comprises at least one foamed layer and at least one modification layer, and the polyurethane resin solution layer is provided on a surface of the polyolefin elastomer composite layer away from the substrate layer.

An abrasion resistant finish for a fungal material, the finishing comprising an optimum quantity biodegradable polylactic acid plastic (PLA) dispersed in water to produce a PLA mixture. When the PLA mixture is applied to the fungal material, water carries the PLA deeply into the matrix of the fungal hyphae to a depth at least 2 N/10 mm or 1% of the thickness of the fungal material, whichever is greater. The finish fortifies the hyphal structure as the water evaporates and creates a PLA coating on the fungal material with improved abrasion resistance and water resistance.

The present disclosure relates to a synthetic leather including a base material layer containing a fiber base material, in which at least a part of the synthetic leather contains a polypeptide derivative, the polypeptide derivative contains a block copolymer containing a first segment containing a polypeptide skeleton, and one or a plurality of second segments that are bonded to the first segment, the polypeptide skeleton is a recombinant polypeptide skeleton or a hydrophobic polypeptide skeleton, and the second segment contains a molecular group having a plasticizing function for the polypeptide skeleton.
