A method of manufacturing bulked continuous carpet filament that includes providing a polymer melt and separating the polymer melt from the extruder into at least eight streams. The multiple streams are exposed to a chamber pressure within a chamber that is below approximately 25 millibars, or another predetermined pressure. The streams are recombined into a single polymer stream. Polymer from the polymer stream is then formed into bulked continuous carpet filament.

A method of producing an exercise weight structure comprises mixing a particulate material with a binder material and molding the resulting mixture to an appropriate shape. An outer skin for the exercise weight structure is firstly formed of a resilient material, and forms a mold into which an inner weight section or body is molded or cast. The inner weight section and the outer skin are both formed of recycled material and include a common binder material.

A method of reprocessing a fiber composite part to form a preform is provided including determining a location having a longest stretch of continuous, unidirectional fibers in the part, determining an axis generally closest to and parallel to the fibers at the location, suspending the part from an anchor point within a heated cavity, heating the part to a temperature above a glass transition temperature and below a melting temperature of the resin of the part, and applying at least one force vector to the composite part, the sum of such vectors being parallel to the axis, wherein fibers of the part realign in a direction generally parallel to the sum of the force vectors, and wherein the composite part yields in the direction of the at least one applied force vector to provide a preform.

The invention relates to a sound protection panel for cladding a wall of an automotive vehicle, the panel includes a mass-spring system. The panel has a lower spring layer based on a resiliently compressible material, an upper mass layer based on resiliently compressible foam flakes, the flakes being bound together by a two-component fibre-based bonding agent comprising a core. The core is fusible at a high temperature or infusible, and a sheath fusible at a lower temperature, the flakes being fused with the sheath to form an upper agglomerated layer.

A waste tire resourceful regeneration treatment method is provided, including: step S1, sorting, including: sorting waste tires according to types of the waste tires to obtain target waste tires with steel wires; and step S2, bead-cutting, including: performing a bead-cutting process on the target waste tires through a bead-cutting machine, to cut the target waste tires into beads and first remaining portions separated from the beads. With respect to the method, the target waste wires with steel wires are sorted out from waste wires of different types, a bead-cutting machine is used to remove beads with steel wires from the waste tires with steel wires and separate the steel wires from the beads with steel wires, then a series of processes including cleaning, crushing, magnetic separation, fiber separation, sieving, desulphurizing, and cooling are performed to obtain recycled resources of the waste tires.
