Processable sheet with excellent rigidity and process for producing the same

摘要

A processable sheet which is inexpensive and has exellent rigidity can be manufactured easily and safely without a need of any special apparatus. The sheet comprises a fibrous layer and a multi-layer film on one surface or both surfaces of the fibrous layer. The fibrous layer comprises highly entangled conjugate fibers each of which has a structure of a core and a sheath. The core is made of a high melting point-thermoplastic resin (B) and the sheath is made of a low melting point-thermoplastic resin (A). The multi-layer film comprises an outer thermoplastic resin (C) which is highly compatible with the low melting point-thermoplastic resin (A). Tho fibrous layer and the multi-layer film, as well as the contact points of the conjugate fibers, are melt-bonded to each other by a thermal treatment.
