Laminated fabric of polypropylene

A process for forming a laminated fabric comprising the steps of conveying a pre-formed layer of woven polypropylene yarns from a storage location to a spraying station, conveying a pre-formed layer of non-woven polypropylene material from a storage location to said spraying station, spraying one surface of said woven polypropylene yarn and one surface of the non-woven polypropylene material with a solvent-based adhesive, conveying said pre-formed layer of woven polypropylene yarn and said pre-formed layer of non-woven polypropylene material to a bonding station whereat said pre-formed layer of woven polypropylene yarn and said pre-formed layer of non-woven polypropylene material are bonded together under pressure at a temperature below 200.degree. F. to produce a unitary fabric structure having greater strength and stability characteristics than the layer of woven polypropylene yarns without shrinkage or distortion of the characteristics of the polypropylene yarns.
