Claims
- 1. A method for producing a nonwoven material having at least one layer of continuous filaments, the method comprising laying a first web of continuous filaments on a wire or other permeable support member having a resilient extensibility in a transverse direction and which substantially resumes its original dimension when the extension is discontinued, wherein the wire is stretched in the transverse direction to at least 120% of its original width when the continuous filaments are laid on the wire, and discontinuing the stretching after the continuous filaments have been laid on the wire.
- 2. The method as claimed in claim 1, wherein the wire is stretched to at least 130% of its original width when the continuous filaments are laid on the wire.
- 3. Method as claimed in claim 1, wherein after discontinuation of the stretching of the wire a second web of natural fibres and synthetic staple fibres are laid on top of said first web of continuous filaments.
- 4. Method as claimed in claim 3, wherein said second web contains cellulose fibres.
- 5. Method as claimed in claim 3, wherein the second fibrous web is is dry-, wet- or foam formed.
- 6. Method as claimed in claim 3, wherein the second fibrous web are hydroentangled together.
- 7. The method as claimed in claim 1, wherein the wire is stretched to at least 150% of its original width when the continuous filaments are laid on the wire.
- 8. Method as claimed in claim 1, wherein after discontinuation of the stretching of the wire a second web of natural fibres or synthetic staple fibres are laid on top of said first web of continuous filaments.
- 9. The method as claimed in claim 1, wherein the continuous filaments are spunbound fibers.
- 10. The method as claimed in claim 1, wherein the continuous filaments are meltblown fibers.
