subject: Structure Of Slipper [print this page] A slippers wholesale having a structure consisting of unfoamed surface layers, an internal closed-cell layer and intermediate open-cell layers. This improved slippers wholesale is produced by adding a foaming material comprising short lengths of fiber and a blowing agent to a thermoplastic resin, melting the resulting composition, forcing the melt into a fixed-cavity mold and cooling the melt to solidify.
A slippers wholesale comprising a main body and a strap which are integrally molded of synthetic resin, said main body consisting of a central closed-cell layer containing a suitable distribution of short lengths of fiber, a couple of intermediate open-cell layers containing a suitable distribution of short lengths of fiber one disposed on each side of said closed-cell layer and a couple of unfoamed resin surface layers containing a suitable distribution of short lengths of fiber one disposed on each of the outer sides of the corresponding open-cell layer.
A main object of the present invention is to provide a novel slippers wholesale of which a slippers wholesale main body and a strap main member are integrally and simultaneously molded.
A further object of the present invention is to provide a novel synthetic resin foam slippers wholesale having an internal three-layer structure.
A further object of the present invention is to provide a novel synthetic resin foam slippers wholesale having an internal three-layer structure, the main body of said slippers wholesale having a shank inside so as to provide durability and resistance against deformation of the slippers wholesale.
These objects can be accomplished by blending a foaming material comprising an intimate mixture of short lengths of fiber and a blowing agent with a thermoplastic synthetic resin or a thermoplastic synthetic resin composition containing a plasticizer, stabilizer and pigment, melting the blend, casting the melt into a metal mold having a fixed cavity and, finally, cooling the melt to solidify.
