POLYESTER FILM HAVING LAMINATED STRUCTURE AND METHOD FOR MANUFACTURING THE SAME
A polyester film having a laminated structure and a method for manufacturing the same are provided. The polyester film has at least two polyester film layers. Each of the polyester film layers includes a physically recycled polyester resin and a chemically recycled polyester resin. The physically recycled polyester resin is formed by a plurality of physically recycled polyester chips. The chemically recycled polyester resin is formed by a plurality of chemically recycled polyester chips, and is mixed with the physically recycled polyester resin. The plurality of chemically recycled polyester chips further includes chemically recycled electrostatic pinning polyester chips. The chemically recycled electrostatic pinning polyester chips contain electrostatic pinning additives, and the electrostatic pinning additives are metal salts. The at least two polyester film layers are a white polyester film layer and a black polyester film layer, respectively.

Methods and systems for processing mixed textile feedstock, isolating constituent molecules, and regenerating cellulosic and polyester fibers
Methods and systems of the present invention use mixed textile feedstock, which may include post-consumer waste garments, scrap fabric and/or other textile materials as a raw feed material to produce isolated cellulose and other isolated molecules having desirable properties that can be used and be used in the textile and apparel industries, and in other industries. A multi-stage process is provided, in which mixed textile feed material is subjected to one or more pretreatment stages, followed by at least two pulping treatments for isolating cellulose molecules and other molecular constituents, such as polyester. The isolated cellulose and polyester molecules may be used in a variety of downstream applications. In one application, isolated cellulose and polyester molecules are extruded to provide regenerated cellulose fibers and regenerated polyester fibers having desirable (and selectable) properties that are usable in various industrial applications, including textile production.

Inter-penetrating elastomer network derived from ground tire rubber particles
Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.
