Abstract
Abstract A fashion felt of laminar structure comprising two outer layers at least one of which consists essentially of melt fibres, a layer of synthetic fibres, preferably synthetic fibre waste, positioned between the two outer layers, and a layer of surface batt secured to one of the outer layers. The laminar fashion felt possesses a high degree of plasticity and is given the desired shape in heat and compression treatments and the desired outlines in cutting operations. By varying the thickness of the batt layer and by compressing different parts of the product to a larger or lesser extent, the degree of softness or hardness of the product could be chosen in accordance with the end use thereof. The fashion felt is particularly useful for furniture and car interior upholstery and fittings. The invention also concerns a method of producing the felt.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
97 words
An improved fashion felt comprising a first outer layer and a second outer layer, at least one of said outer layers consisting essentially of melt fibres, a third layer of synthetic fibres, preferably synthetic fibre waste, positioned intermediate said first and second layers thus separating said layers, said first and second layers interconnected to said third intermediate layer by needling, and a layer of surface batt secured to said first outer layer by means of needling, said felt having been given the desired shape in heat and compression treatments and the desired outlines through cutting, preferably stamping.
Claim 2
Dependent Claim
97 words
An improved fashion felt comprising a first outer layer and a second outer layer, at least one of said outer layers consisting essentially of melt fibres, a third layer of synthetic fibres, preferably synthetic fibre waste, positioned intermediate said first and second layers thus separating said layers, said first and second layers interconnected to said third intermediate layer by needling, and a layer of surface batt secured to said first outer layer by means of needling, said felt having been given the desired shape in heat and compression treatments and the desired outlines through cutting, preferably stamping.
Claim 3
Dependent Claim
26 words
An improved fashion felt as claimed in claim 1, wherein said first outer layer supporting said surface batt consisting of texturized melt fibres, preferably polypropene fibres.
Claim 4
Dependent Claim
22 words
An improved fashion felt as claimed in claim 1, wherein said second outer layer opposite said surface batt consists of a film.
Claim 5
Dependent Claim
147 words
An improved method of producing an improved fashion felt, comprising the steps of applying onto a continuously advancing web of melt fibres a layer of synthetic fibres, preferably synthetic fibre waste, applying an outer layer of melt fibres on top of said synthetic fibre layer, bonding together by means of needling said three layers composed of said melt fibre web, said synthetic fibre layer and said layer of melt fibres, turning the thus formed composite web by passing said web round rollers, applying a surface batt on said web, securing said surface batt to said web by needling, winding the thus formed web product onto a supply roll, withdrawing said web product from said roll and feeding it into an oven to heat said web and layer of melt fibres, and thereafter imparting the desired shape and structure to said heated web product in a pressing tool.
Claim 6
Dependent Claim
147 words
An improved method of producing an improved fashion felt, comprising the steps of applying onto a continuously advancing web of melt fibres a layer of synthetic fibres, preferably synthetic fibre waste, applying an outer layer of melt fibres on top of said synthetic fibre layer, bonding together by means of needling said three layers composed of said melt fibre web, said synthetic fibre layer and said layer of melt fibres, turning the thus formed composite web by passing said web round rollers, applying a surface batt on said web, securing said surface batt to said web by needling, winding the thus formed web product onto a supply roll, withdrawing said web product from said roll and feeding it into an oven to heat said web and layer of melt fibres, and thereafter imparting the desired shape and structure to said heated web product in a pressing tool.
Claim 7
Dependent Claim
43 words
An improved method as claimed in claim 4, comprising heating the web face opposite said surface batt in the passage thereof between said oven and said pressing tool, preferably by exposing said face to infra-red heat, whereby a water-impermeable surface layer is formed.
