Recyclable thermoplastic moldable nonwoven liner for office partition and method for its manufacture |
摘要 |
A rigid thermoformable recyclable nonwoven liner material is formed by a wet process on a papermaking machine. The rigid thermoformable nonwoven liner material is intended to be laminated to a woven fabric and then thermomolded around a wooden panel to form an office partition. The wet-laying process may consist entirely of conventional steps. The fiber furnish includes polyester matrix fibers and co-polyester/polyester bicomponent binder fibers. The web of fibers coming off the papermaking machine is passed through a foam press, which applies a water-based medium having polyvinyl chloride binder dispersed therein. The web is dried, treated again with a water-based medium having polyvinyl chloride binder dispersed therein and then dried again. The final product can be molded in a wide range of temperatures ranging from 225° to 300° F.
