Abstract
Multi-layer covering articles having a base layer adapted to yieldably conform to a surface to be covered and having properties appropriate for a particular application in which the article is to be used, and a thermoplastic surface layer bonded to a surface of the base layer and incorporating a reinforcing material to provide strength and tear resistance for the covering article. The reinforcing material permits the surface layer to function as the strength-providing member of the article, permitting the base layer to be designed solely in accordance with the requirements of a particular application without regard to its strength. Preferred embodiments of the invention include a concrete curing blanket in which the base layer includes a porous, non-woven synthetic fabric having optimum liquid retention and spreading properties and which is very thin and light in weight, and a solar heating swimming pool cover in which the base layer is formed of a plastic bubble sheet and the surface layer includes a black or other heat-absorbing color layer for heating water in the pool by conduction of solar energy therethrough. The reinforcing layer allows for lightweighting of the total product with the ability, if desired, to add dark and light (reflective) sides or the traditional translucent look in lightweight form.
