Abstract
Abstract A molded hat having improved shape retention and recoverability properties wherein the fabric of the crown and brim comprises a single unit eliminating the need for sewing the brim to the crown, said fabric containing a stabilizing polymeric composition. These molded hats are prepared by placing the stabilized fabric in a hat mold and thereafter applying heat and pressure to effect the desired shape. The improved shape retention and recoverability properties result from the presence of the polymeric composition in the fabric.
