Title (EN) A DISCONTINUOUS HYDROCOLLOID ARTICLE
(FR) ARTICLE HYDROCOLLOÏDE DISCONTINU
Abstract: front page image
(EN)A discontinuous hydrocolloid article is disclosed that provides for a high rate of water absorption and a high rate of water vapor transmission. Also, disclosed is a method of making a discontinuous hydrocolloid article. In one embodiment, the discontinuous hydrocolloid article comprises a plurality of cross-linked polymer strands comprising a hydrophobic polymer and a hydrocolloid dispersed throughout the hydrophobic polymer and a plurality of joining strands. Each polymer strand repeatedly contacts an adjacent joining strand at bond regions.
(FR)L'invention concerne un article hydrocolloïde discontinu présentant un taux élevé d'absorption d'eau et un taux élevé de transmission de vapeur d'eau. L'invention concerne également un procédé de fabrication d'un article hydrocolloïde discontinu. Dans un mode de réalisation, l'article hydrocolloïde discontinu comprend une pluralité de brins de polymère réticulé comprenant un polymère hydrophobe et un hydrocolloïde dispersé dans tout le polymère hydrophobe ainsi qu'une pluralité de brins de jonction. Chaque brin de polymère entre en contact répété avec un brin de jonction adjacent au niveau de régions de liaison.
