A method of producing a divided conduit containing, in order forming a strip-shaped textile having a first longitudinal edge and a second longitudinal edge, extruding a molten thermoplastic polymer into the form of an at least partially molten conduit having an inner surface and an outer surface, and placing at least one strip-shaped substrate within the at least partially molten conduit during or directly after conduit formation such that the first longitudinal and second longitudinal edges of the strip-shaped substrate embed into the inner surface of the conduit. The strip-shaped textile is selected from the group consisting of a woven, non-woven, and knit and the strip-shaped textile is air permeable. The inner surface and outer surface of the conduit is continuous.

Process for forming a divided conduit

A divided conduit containing a thermoplastic conduit and at least one strip-shaped film having a first longitudinal edge and a second longitudinal edge which are embedded into the inner surface of the conduit forming at least two flexible, longitudinal channels for enveloping cables or other elongated structures.

Divided conduit

A method of producing a divided conduit comprising forming a strip-shaped substrate having a first longitudinal edge and a second longitudinal edge. The strip-shaped substrate is a strip-shaped textile or a strip-shaped film. Then extruding a molten thermoplastic into the form of a conduit and placing the one strip-shaped substrate within the extruded conduit during or directly after conduit formation. The first longitudinal edge and the second longitudinal edge of the strip-shaped substrate adhere to or embed into the inner surface of the conduit.

A divided conduit containing a thermoplastic conduit and at least one strip-shaped textile. The strip-shaped substrate may be a strip-shaped textile or a strip-shaped film and has a first longitudinal edge and a second longitudinal edge which are adhered to or embedded into the inner surface of the conduit forming at least two flexible, longitudinal channels for enveloping cables or other elongated structures.

The present invention is a durable composite consisting of a polyester knitted fabric and an extruded film that are heat laminated together without the use of additional adhesive. The open-mesh structure of the fabric, when combined with the film, results in improved sound dissipation for the composite as compared with conventional textile headliners. Because both the fabric and the film components have flame retardant constituents, the resulting composite is capable of meeting even the most stringent of flammability requirements. An optional backing layer may be added to the film layer to create a three-layer composite, which may be suited for certain applications.

Composite fabric for vehicles

A warp-knitted fabric of at least three-bar construction, which is comprised of multifilament synthetic pile yarns on the technical back which are raised or broken to produce a plush surface and monofilament synthetic ground yarns on the technical face, the pile yarns being comprised of microdenier filaments having a denier no greater than 1.1.
