1,088,657. Laminates. TECHNICAL INFORMATION SERVICE. June 14, 1965 [March 8, 1965], No. 25033/65. Heading B5N. A process for the fabrication of non-woven textile products comprises the fabrication of at least two fibre batts, the separate needling of each fibre batt on a needle loom, the bringing together of the needled batts and their securing together, so that the top and bottom fibre batts of this assembly show as outer surface that side of the individual fibre batt which is opposite to the one into which the needles of the aforesaid needleloom have last penetrated. The fibre batts which are of natural and/or synthetic fibres, e.g. wool, are secured together by gluing, sticking, bonding, spraying with a binder containing two components with a polyurethane base, sewing or knitting. A reinforcing and/or insulating layer of, e.g., foam rubber or P.V.C. foam, may be inserted between two of the batts before bonding them together, and after bonding a quilted effect can be obtained by seaming or calendering. In all embodiments, after securing, the fibre batts may be subjected to finishing operations such as smoothing, raising, beating, brushing, curling, or frizzing and/or are provided with a hair covering. During or after its needling each fibre batt may be reinforced with binding means, fabric or foam backing. The process can be used to produce a blanket having " winter " and " summer sides, the blanket being produced by unwinding two needled fibre batts from rolls, spraying one of the batts with a binder, bringing the two batts together, calendering, drying the binder, treating the assembly on a raising machine, cutting the assembly into blankets and seaming off with a ribbon.
