Abstract

A waterproof cloth is provided that solves the problem in durability of the conventional biodegradable plant-derived component resin, such as a polylactic acid resin, and exhibits excellent comfort. The waterproof cloth contains a cloth having formed on one surface thereof by a coating method or a joining method a waterproof layer containing a polyurethane resin film containing from 10 to 65% by weight of a plant-derived component.

Description

technical field [0001] The present invention relates to a water-repellent processed fabric, more specifically, to a comfortable water-repellent processed fabric suitable for sports, especially outdoor sports clothes, raincoats, etc. Environmental load in global warming countermeasures, water-repellent processed fabrics containing plant-derived components that contribute to carbon neutrality. Background technique [0002] Regarding a water-repellent finished fabric containing a plant-derived component, for example, Patent Document 1 discloses a porous water-repellent finished fabric with good biodegradability using a polylactic acid resin as a plant-derived component. [0003] However, conventional water-repellent finished fabrics having good biodegradability may cause problems in terms of durability in practical use when applied to sportswear, raincoats, and the like. That is, the present situation is that in the current general polylactic acid fiber, it is difficult to mai...
