Abstract
Abstract The carpet backing materials comprise a woven, non-woven or knitted thermoplastic backing fabric, preferably at least partially incorporating polyolefin, in particular polypropylene, yarns, to which a fleece is adhered by means of a hot melt powder adhesive having a softening point below that of the thermoplastic backing fabric. The fleece may, if desired, be pretreated to form a self-supporting web prior to being adhered to the backing fabric. A process for the preparation of the carpet backing materials and tufted carpets incorporating the backing materials are described and exemplified. When incorporated into tufted carpets, the backing fabrics avoid the problem of grinning, and improve tuft locking and dimensional stability of the finished carpets.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
51 words
A carpet backing material comprising a woven, non-woven or knitted theromplastic backing fabric to which a substantially flat fleece is attached, characterised in that the fleece is adhered to the backing fabric by means of a hot melt powder adhesive having a softening point below that of the thermoplastic backing fabric.
Claim 2
Dependent Claim
51 words
A carpet backing material comprising a woven, non-woven or knitted theromplastic backing fabric to which a substantially flat fleece is attached, characterised in that the fleece is adhered to the backing fabric by means of a hot melt powder adhesive having a softening point below that of the thermoplastic backing fabric.
Claim 3
Dependent Claim
79 words
A carpet backing according to claim 1, characterised in that the fleece adhered to the backing fabric comprises at least a first fibre component whose fibres have a softening point above that of the hot melt adhesive and prior to adhesion of the fleece to the backing fabric the fleece has been heated to a temperature equal to or greater than the softening point of the said first fibre component to cause the fleece to form a self-supporting web.
Claim 4
Dependent Claim
29 words
A carpet backing according to claim 1 or claim 2, characterised in that the backing fabric at least partially incorporates polypropylene yarns, and the fleece comprises nylon-6 and/or nylon-66.
Claim 5
Dependent Claim
121 words
A process for the manufacture of a carpet backing material according to claim 1 which comprises attaching a substantially flat fleece to a woven, non-woven or knitted thermoplastic backing fabric, characterised in that a hot melt powder adhesive having a softening point below the softening point of the backing fabric is applied to the backing fabric, the backing fabric and applied powder adhesive is heated to a temperature sufficient to melt and fuse said adhesive to the backing fabric but below the softening point of the backing fabric to form a coated backing fabric and subsequently the fleece is applied to the coated backing fabric while the adhesive is still active in order to adhere said fleece to the coated fabric.
Claim 6
Dependent Claim
69 words
A process according to claim 4, characterised in that the fleece comprises at least a first fibre component whose fibres have a softening point above that of the powder adhesive and prior to application of the fleece to the coated backing fabric the fleece is heated to a temperature equal to or greater than the softening point of the fibre component to cause it to form a self-supporting web.
Claim 7
Dependent Claim
28 words
A process according to claim 4 or claim 5, characterised in that the backing fabric at least partially incorporates polypropylene yarns and the fleece comprises nylon-6 and/or nylon-66.
Claim 8
Dependent Claim
21 words
A tufted carpet characterised in that it incorporates a carpet backing material according to any one of claims 1 to 3.
