Abstract
Self-bonded nonwoven web and woven fabic composites comprising at least one layer of a uniform basis weight self-bonded, fibrous nonwoven web comprising substantially randomly disposed, substantially continuous thermoplastic filaments adhered to at least one layer comprising woven thermoplastic yarns in the form of woven fabrics such as wall covering fabric, softside luggage fabric and leno weave fabric.
Claims18
A self-bonded nonwoven web and woven thermoplastic yarn composite comprising,
- at least one layer of a uniform basis weight self-bonded, fibrous, nonwoven web comprising a plurality of substantially randomly disposed, substantially continuous thermoplastic filaments wherein said web has a Basis Weight Uniformity Index of 1.0.+-.0.05 determined from average basis weights having standard deviations of less than 10%, adhered to
- at least one layer comprising woven thermoplastic yarns.
A softside luggage fabric comprising,
- at least one layer of a uniform basis weight self-bonded, fibrous nonwoven web comprising a plurality of substantially randomly disposed, substantially continuous thermoplastic filaments having deniers in the range of about 0.5 to about 20 and wherein said web has a Basis Weight Uniformity Index of 1.0.+-.0.05 determined from average basis weights having standard deviations of less than 10%, and
- at least one layer of a woven fabric having a plain weave construction with warp yarns having about 10 to about 48 warp ends per inch with deniers in the range of 200 to about 5000 and fill yarns having about 8 to about 30 pick ends per inch with deniers of about 200 to about 6000 wherein the woven fabric is adhered to the self-bonded, fibrous nonwoven web with a polymeric composition.
A wall covering fabric comprising,
- at least one layer of a uniform basis weight self-bonded, fibrous nonwoven web comprising a plurality of substantially randomly disposed, substantially continuous thermoplastic filaments having deniers in the range of about 0.5 to about 20 and wherein said web has a Basis Weight Uniformity Index of 1.0.+-.0.05 determined from average basis weights having standard deviations of less than 10%, and
- at least one layer of a woven fabric having a plain weave construction with warp yarns having about 10 to about 48 warp ends per inch with deniers in the range of 400 to about 5000 and fill yarns having about 8 to about 20 pick ends per inch with deniers of about 400 to about 6000 wherein the woven fabric is adhered to the self-bonded, fibrous nonwoven web with a polymeric composition.
A leno fabric comprising,
- at least one layer of a uniform basis weight self-bonded, fibrous nonwoven web comprising a plurality of substantially randomly disposed, substantially continuous thermoplastic filaments having deniers in the range of about 0.5 to about 20 and wherein said web has a Basis Weight Uniformity Index of 1.0.+-.0.05 determined from average basis weights having standard deviations of less than 10%, and
- at least one layer of a woven fabric with warp yarns having about 7 to about 13 warp ends per inch and deniers ranging from about 450 to about 550 and fill yarns having about 4 to about 7 pick ends per inch and deniers ranging from about 950 to about 1050 adhered to the self-bonded, fibrous nonwoven web with a polymeric composition.
