ABSTRACT:
A process of producing a tufted pile fabric comprises providing a primary backing which may be woven, non-woven or knitted fabric and containing for example polypropylene, polyester, polyamide, jute or viscose rayon, applying a meltable fibrous layer to both sides of the primary backing, preferably by needling fibres into the backing, inserting pile tufts into the primary backing so that parts of the pile tufts extend through backing and the meltable fibrous layers and melting the fibrous layer which is on the side of the backing opposite the pile forming surface of the tufts to secure the tufts to the backing and provide an anchor coat for the fabric. The meltable fibre may be polyamide fibre with a melting point in the range 80.degree.-150.degree. C. and may conveniently be Grilon K115 (Grilon is a Registered Trade Mark). The process may be used to provide mother and daughter tufted pile fabrics by applying a second primary backing with meltable fibrous layers applied thereto to the pile forming surface of the first fabric and melting the fibrous layers of the second primary backing to adhere the latter to the pile forming surface of the tufts, and thereafter slitting the tufts intermediate the two primary backings.
