Abstract
Upholstery material and shoe upper material made from a base sheet of criss-crossing elastomeric polyurethane fibers running parallel to the surfaces of the sheet, said fibers being bonded together at their points of contact. In one preferred form the product has a preformed skin whose thickness is less than about 100 microns and preferably less than about 50 microns, such as about 20 to 40 microns and the skin is joined to the fibers of the base sheet by spaced fingers of a binder.
Claims10
A sheet comprising criss-crossing fibers, of elastomeric polyurethane, running parallel to the surfaces of the sheet, said sheet containing a polymeric binder of elastomeric polyurethane adhered to said fibers within said sheet, the weight ratio of said binder to said fibers being in the range of about 1:10 to 6:10, said fibers being bonded together at their points of contact, the pores of said sheet constituting about 2/5 to 182 of the volume of said sheet, the proportion and position of said binder being such that the interior of said sheet has a structure of said criss-crossing fibers running parallel to the surfaces of the sheet with open pathways between intersecting fibers and there are bodies of said binder which each surround, and are firmly bonded to, a plurality of overlying intersecting fibers in the interior of said sheet.
