    摘要： A process for preparing thermoplastic piping for recovery of the thermoplastic in which the piping is cut into a continuous spiral ribbon with straightening of this ribbon to be without substantial curvature and cutting of the straightened ribbon into pieces. Preferably, the process produces pieces of thermoplastic of sufficiently small size to be suitable for feeding to an extruder. An apparatus for preparing thermoplastic piping for recovery of the thermoplastic which combines means for cutting the thermoplastic piping into a continuous spiral ribbon with means for straightening the spiral ribbon so that it is without substantial curvature and means for cutting the straightened ribbon into pieces.

    摘要： Selvedge from carpeting containing meltable resin content is heated to melt and degrade said resin which is then separated by screening or straining from any solid residue. As an example, tufted carpeting having nylon yarn pile secured in a woven polypropylene primary back which is bonded by a thermoplastic adhesive to the pile yarns and to a secondary back of woven jute is so treated to separate a significant quantity of the resin from the jute. The jute residue may be incinerated to utilize the latent thermal energy therein. Alternatively, the secondary back may be of thermoplastic material or may be omitted. The reclaimed degraded resin is then substituted for the high molecular weight copolymer which constitutes a component of the adhesive for subsequent carpet manufacture.The process may be carried out in a double-walled vessel wherein the inner wall is pervious or it can be carried out with apparatus having a moving web of pervious material for supporting the selvedge or the like.

    摘要： A method an apparatus for reclaiming face fibers and polypropylene and/or polyvinyl chloride backing material from rolls and pieces of post-consumer carpet. The system includes a separator for separating the face fibers from the backing and for separating latex and carbon calcium powder from polypropylene backing. An extruder is provided for extruding the face fibers separated from the backing into extrusions, and a pelletizer pelletizes the extrusions. A roller opener opens the polypropylene backing into fibrous portions and also cleans such fibrous portions. Alternately, a granulator can be provided that chops and grinds the polypropylene or PVC backing into fragments after the separation of the face fibers from the backing. A heat source heats the PVC fragments, and also the polypropylene fragments (thereby separating the latex therefrom), and ultimately melts such fragments. Reclaimed fibers can be pelletized, made into extrusions, used in non-woven products and in other manners.

    摘要： A method of forming a reinforced building product from garbage, comprising the steps of sorting garbage, shredding plastics within the garbage, shredding fibers within the garbage, heating the shredded plastics, forming a slurry from the plastics and fibers, disposing the slurry within an extrusion cavity, extruding the fluid through a venturi, and allowing the extruded materials to cool. Garbage is separated into plastics, fibers, and other materials. Plastics are shredded to facilitate melting. Fibers are shredded to macroscopic lengths no greater than a maximum internal diameter of a venturi. The plastics are melted. The melted plastics are mixed with fibers and other material to form a slurry that is extruded from a cavity through a venturi, thereby causing significant alignment of the shredded fibers within the slurry in an outer region of the extruded slurry. Cooled, there is reinforced building material.

    摘要： A method of recycling spent filter media is disclosed. The method can include providing a cloth, the cloth being spent polymer-base filter media, removing foreign solid particles from the cloth, washing the cloth, drying the cloth and processing the dried cloth to produce polymer-base particles that can be used to produce a component. The processing of the dried cloth can include densifying and/or granulating the dried cloth. In addition, the spent cloth can have been used as metal working filtration media and the foreign solid particles removed from the cloth using a brush. In some instances, the cloth is washed using a dry cleaning process and the granulating or densifying of the cloth produces particles that can be used in an injection molding machine.

    摘要： The present invention concerns a method for recycling used floor covering. Post-consumer or post-industrial fibrous floor coverings are shredded to form a fibrous dispersion. The dispersion is maintained at a content of about 20-65% low-melt thermoplastic. The shredded fibrous dispersion is conveyed into a chute feeder which converts it into a batt that is heated, compressed, and cooled to form a durable backing particularly suitable for flooring applications. The batt comprises vertical layers or strata of fibers to provide additional cushion for the backing. Additionally, a portion of the shredded fibrous dispersion can also be diverted and used to form a face layer and/or adhesive layer for a reconstituted floor covering.

    摘要： A method of recycling bonded fibrous materials, the method includes the steps of: providing pieces of bonded fibrous materials, the pieces having sizes that are adapted for suspension in a liquid; suspending the discrete pieces of bonded fibrous materials in a liquid; applying mechanical work to the liquid suspension of discrete pieces to generate hydraulic pressure and mechanical shear stress conditions sufficient to hydraulically fragment the bonded fibrous materials into fibers and fiber-like components; and separating substantially individual fibers and fiber-like components from the liquid. The method is used to produce recycled synthetic fibers and fiber-like materials that have at least one thread element composed of synthetic material having at least one irregular distortion generated by hydraulic fracture of the thread element to separate it from a bonded fibrous material while the bonded fibrous material is suspended in a liquid.
