LEATHER-LIKE FORMED ARTICLE

摘要

PURPOSE:To obtain the subject formed article having high hygroscopicity similar to natural leather by mixing spherical sericin having particle diameter smaller than a specific level into a synthetic rubber or a synthetic resin and heat- forming the mixture. CONSTITUTION:Sericin having spherical form of <=20mum in diameter is mixed into a synthetic rubber (e.g. butadiene or olefin rubber) or a thermoplastic resin (e.g. vinyl acetate resin) and the obtained compound is heat-formed by conventional method to obtain an excellent leather-like formed article resembling natural leather in the surface nature and having high hygroscopicity.
