Abstract

1,131,517. Plastics/fabric laminates. HERCULES Inc. 18 May, 1966 [18 May, 1965], No. 22196/66. Heading B5N. A mouldable fabric comprises a laminate of a thermoplastic film and a backing fabric which contains polypropylene and cellulosic fibres in a ratio of polypropylene to cellulosic fibres within the range of from 2:1 to 20:1 by weight. The cellulosic component may be included in the backing fabric as a component of a composite yarn of blended staple fibres in the ratio 70- 90% polypropylene and 30-10% cellulosic. Alternatively the cellulosic component is in the form of unblended strands interwoven or knit with the polypropylene component. The backing fabric may be a woven or knit fabric or a chemically or mechanically bonded non-woven fabric. To produce the mouldable fabric a film of thermoplastic material is preheated above its softening point and then passed through heated calender rolls under pressure together with the backing fabric. Alternatively the thermoplastic film is melt extruded on to a running length of backing fabric and then calendered, or the film and backing fabric are secured together by adhesive. The laminated fabric may be embossed either by using embossing rollers after joining the backing fabric to the film or by using engraved moulds in the moulding step. The moulding may occur in unheated or heated moulds with the fabric being preheated in the former case and optionally in the latter case. In one example the fabric is clamped loosely in the frame of a compression mould; is heat shrunk until it becomes taut in the frame, and then moulded. In the examples given a plain weave backing fabric containing 91% polypropylene fibres and 9% rayon or cotton fibres is heat set at 300‹ F. This fabric is then calendered to a film of p.v.o. at 215‹ F. In another example a jersey knit fabric of 80% polypropylene/20% cotton composite yarn is laminated to a vinyl film and then moulded to form a typewriter case. The thermoplastic films may be of polyvinyl chloride, polyethylene, polypropylene, cellulose acetate, or a copolymer of vinyl chloride with vinyl acetate or vinylidene chloride. A second thermoplastic layer may be applied to the opposite side of the backing fabric by sprinkling powdered thermoplastic material, e.g. polyethylene or polypropylene, on the backing fabric in the mould prior to preheating. Upon being heated the thermoplastic material melts and forms a mouldable film. The mouldable fabrics of the invention can be used as book covers or in upholstery and are scuff resistant, durable and moisture resistant.
