Abstract
A carrier material includes at least a first thermoplastic fiber layer and a second thermoplastic fiber layer. At least a part of the first thermoplastic fiber layer and/or the second thermoplastic fiber layer at at least one boundary of the carrier material is removed, to provide a first part of a form-fit connection. The carrier material can be used in bituminous roofing membranes, roofing underlayment sheets, carriers for filter media, primary backings for tufted carpets and (cushion) vinyl floor coverings.
Claims15
A carrier material comprising at least a first thermoplastic fiber layer and a second thermoplastic fiber layer, wherein the first thermoplastic fiber layer and the second thermoplastic fiber layer are nonwoven thermoplastic fiber layers, wherein at least a part of the first thermoplastic fiber layer and/or the second thermoplastic fiber layer at at least one boundary of the carrier material is removed, to provide a first part of a form-fit connection.
A method of manufacturing a carrier material comprising the following steps:
- a. supplying a carrier material comprising at least a first thermoplastic fiber layer and a second thermoplastic fiber layer
- b. removing at least a part of the first thermoplastic fiber layer and/or second thermoplastic fiber layer at at least one boundary of the carrier material, and
- c. optionally rolling up the carrier material.
