Abstract

PURPOSE:To obtain smooth-touch composite pad stuff by a method wherein chips made by crushing the waste of skin stuff, knit or woven fabrics and the like are impregnated with a specified quantity of resin liquid with foaming property, filled then on an intermediate material such as rough wool and calico set in a mold for forming and after that are formed monolithically. CONSTITUTION:The chips obtained by crushing cut pieces or wastes of intermediate materials such as skin stuff including polyvinyl-chloride leather, synthetic leather etc., knit and woven fabrics and nonwoven fabrics or of cushion stuff made of polyurethan form and the like into the size of 2-50mm by a crusher are impregnated with an undiluted foaming solution of polyurethan form at the rate of 10-60% or, desirably 20-40% to the weight of chips. And the impregnated chip material 11 thus obtained is filled on an intermediate stuff 10 such as polyurethan- form slab, rough wool, calico and nonwoven fabrics set in the lower mold 9, then pressurised and heated, whereby the undiluted foaming solution being made to foam, and formed solidly, thus the composite pad stuff being obtained.
