A device, to homogenise plastics material melts, has a homogenising element with a plurality of flow channels, which differ with respect to at least one feature from the group length, cross sectional area and cross sectional shape. When flowing through the homogenising element, the plastics material melt is divided into a plurality of part streams, which, in each case, flow through an associated flow channel. When leaving the respective flow channel the part streams have different flow speeds so the plastics material melt is expanded and sheared on transition to a uniform flow. As a result, a homogenisation of the plastics material melt takes place in a simple, efficient and effective manner.

A thermoplastic artificial leather includes a thermoplastic composite laminate and a textile base. The thermoplastic composite laminate includes a foamed thermoplastic elastic layer, an unfoamed thermoplastic elastic layer and a thermoplastic adhesive layer. The foamed thermoplastic elastic layer has a first surface, a second surface and a plurality of foamed structures. The second surface is opposite to the first surface. The unfoamed thermoplastic elastic layer is disposed on the first surface of the foamed thermoplastic elastic layer. The thermoplastic adhesive layer is disposed on the second surface of the foamed thermoplastic elastic layer. The textile base is laminated on the thermoplastic adhesive layer of the thermoplastic composite laminate.

In particular embodiments, a process for producing bulked continuous carpet filament from recycled polymer utilizes two vacuum pumps in combination with a single extruder. In various embodiments, the dual vacuum arrangement (e.g., at least two vacuum pumps) operably coupled to the single extruder (e.g., MRS extruder) may be configured remove one or more impurities from recycled polymer as the recycled polymer passes through the extruder such that the process: (1) is more effective than earlier processes in removing contaminates and water from the recycled polymer; (2) allows for an increased throughput through a single extruder, which may result in a doubling of a number of thread lines produced from a single extruder; (3) results in a desired intrinsic viscosity for the extruded recycled polymer at the increased throughput; and/or (4) reduces an amount of downtime of a particular production line as a result of cleaning the two vacuum pumps.

The present invention discloses a biaxial or tri-axial eccentric rotor volume pulsed deformation plasticizing method and device. The method is characterized in that: the conveying volume of materials formed between two or three engaged eccentric rotors, which are formed by spiral structures and eccentric cylindrical structures connected alternately, and an inner surface of a stator changes periodically along the axial direction and the radial direction of the rotors, achieving the volume pulsed deformation plasticizing and conveying of the materials during engaged rotation of the two or three engaged eccentric rotors. The device's eccentric rotors are all formed by length-varying spiral structures and eccentric cylindrical structures connected alternately; the spiral structures of the eccentric rotors are engaged to each other; the axial positions of eccentric cylindrical structures of the two or three rotors are the same.
