According to executives at Fare, a leading Italian producer of compact staple fiber extrustion systems, improved recycling processes and equipment will encourage many more companies to adopt recycling measures as a means of improving to adopt recycling measures as a means of improving their bottom line. Until carpet recycling becomes comercially viable, the primary source of recycled polyethylene terephthalate for carpets, fiberfill, and nonwoven fabrics will remain the conversion of plastic bottles into polyester staple fibers. As hydrolysis, glycolysis, and methanolysis become more prevalent alternatives to traditional recycling methods, the polymerization of PET suitable for food grade applications will compete for the raw materials currently targeted for textile use. A substantial quantity of staple fibers is being produced from recycled polypropylene and polyester on compact spinning systems. Compact spinning machines for recycled raw materials require a double filtration system as well as crystallizing and drying equipment.
