SYNTHETIC LEATHER AND METHOD FOR MANUFACTURING SYNTHETIC LEATHER

The present disclosure relates to a multilayer synthetic leather, at least comprising a textile arrangement; and a polyurethane based foam; wherein the polyurethane-based foam is partially fixed to the textile arrangement using a first fixing layer such that the first fixing layer has fixing areas formed by a fixing agent and free areas free from the fixing agent in the same plane.

WETNESS INDICATOR GARMENT
20210161219 · 2021-06-03 ·

The technology described herein relates to a pair of long pants garment panel comprising a pattern of a durable water-repellant (DWR) coating that is selectively applied on to the pant legs of the pair of long pants. The pattern is comprised of a plurality of discrete shapes that are isolated from one another. In other words, the textile material surrounding each discrete shape in the plurality of discrete shapes is not coated by the DWR coating. A size of the plurality of discrete shapes in the pattern is gradually decreased moving up the pant legs starting from a hemmed edge up to a knee area. The pattern is visible during wet conditions and not visible during dry conditions.
