METHOD FOR PRODUCING POLYMERIC FIBER INSULATION BATTS FOR RESIDENTIAL AND COMMERCIAL CONSTRUCTION APPLICATIONS

摘要

Method for producing Fiber insulation batts suitable for building thermal insulating applications are made using polymer fibers such as PET. A mixture of staple fibers and binder fibers are used to make the batt. The batt has a bulk density of 6-14 kg/m3, a thermal conductivity of 35-50 mW/m-K and a lambda*density value of from 250-550. The batts can be made by forming a web of the fibers, and calibrating and heat-setting the web. The web can be formed using pneumatic or mechanical carding processes. In some processes, the batt can be made by forming a stack of multiple plies of the web and calibrating and heat-setting the stack.
