Abstract
Abstract Thermoplastics articles having surfaces laminated to cloth are made without distortion of the cloth by using a melded cloth, that is to say a cloth composed of contiguous conjugate fibres fused together at points where they touch one another. The articles can be made by moulding thermoplastics materials onto melded cloth inserted into a mould.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
91 words
A thermoplastics article having a surface fused to a cloth wherein the cloth comprises at least 25% by volume of contiguous conjugate fibres at least some of which are fused together at at least some of the points where they touch one another, each conjugate fibre comprising two mutually adhering fibre-forming components one of these which forms at least part of the surface of the fibre can be rendered fusible by a treatment which does not significantly affect the other component so as to enable contiguous fibres to be fused together.
Claim 2
Dependent Claim
91 words
A thermoplastics article having a surface fused to a cloth wherein the cloth comprises at least 25% by volume of contiguous conjugate fibres at least some of which are fused together at at least some of the points where they touch one another, each conjugate fibre comprising two mutually adhering fibre-forming components one of these which forms at least part of the surface of the fibre can be rendered fusible by a treatment which does not significantly affect the other component so as to enable contiguous fibres to be fused together.
Claim 3
Dependent Claim
42 words
A thermoplastics article as claimed in claim 1 wherein the cloth comprises conjugate fibres comprising a core of nylon 66 or polyethylene terephthalate in contact with or sheathed in nylon 6 or a nylon 6/nylon 66 copolymer or a polyethylene terephthalate/isophthalate copolymer.
Claim 4
Dependent Claim
26 words
A thermoplastics article according to claim 2 wherein the cloth comprises conjugate fibres comprising a core of nylon 66 enclosed within a sheath of nylon 6.
Claim 5
Dependent Claim
29 words
A thermoplastics article according to claim 2 wherein the cloth comprises conjugate fibres comprising a core of polyethylene terephthalate in contact with or enclosed within a polyethylene terephthalate/isophthalate copolymer.
Claim 6
Dependent Claim
15 words
A thermoplastics article according to claim 1 wherein the thermoplastics material comprises a crystalline polyolefin.
Claim 7
Dependent Claim
22 words
A thermoplastics article according to claim 5 wherein the polyolefin is a polymer of propylene or a copolymer of propylene and ethylene.
Claim 8
Dependent Claim
19 words
A thermoplastics article according to claim 6 wherein the thermoplastics material is in the form of a structural foam.
Claim 9
Dependent Claim
14 words
A thermoplastics article according to claim 1 wherein the article is a furniture component.
Claim 10
Dependent Claim
17 words
A thermoplastics article according to claim 1 wherein the article is a trim for a motor vehicle.
