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.

Abstract: A material for a primary carpet backing including a nonwoven fabric including first bicomponent core/sheath fibers including a first thermoplastic polymer in the core and a second thermoplastic polymer in the sheath and second bicomponent core/sheath fibers including a third thermoplastic polymer in the core and a fourth thermoplastic polymer in the sheath, wherein the first thermoplastic polymer in the core of the first bicomponent core/sheath fibers is of a different polymer family as the third thermoplastic polymer in the core of the second bicomponent core/sheath fibers, and wherein the second thermoplastic polymer in the sheath of the first bicomponent core/sheath fibers and the fourth thermoplastic polymer in the sheath of the second bicomponent core/sheath fibers are polymers of the same polymer family, preferably having the same melting temperature.

Abstract: A nonwoven carrier material including at least a first part and a second part whereby the first and the second part including at least two layers of thermoplastic fibers. The first part and the second part are connected with each other in a connecting area to form the nonwoven carrier material whiteout thickness and weight variations in the connecting area. Further, a method for connecting a first and a second part of a nonwoven carrier material to form a connected nonwoven carrier material.

Abstract: An erosion control system is disclosed for preventing erosion of embankments including a three-dimensional material, the three-dimensional material including void volumes, and a mixture including a particulate material and a binder material included in the void volumes, wherein the binder material includes an organic binder material derived from living matter.
