ResumoAccording to the Ellen MacArthur Foundation, a circular system is a model of industrial economy that is regenerative and restorative in principle, designed to circularly recover the product of its activities. This model was born with the need to transform the prevalent system - which is mainly linear - where raw materials are extracted from nature, transformed into products that are then discarded at the end of their life cycles. This study was devised to develop mixed knitted fabrics - 50% shredded polyester/50% recycled polyester and 50% shredded polyester/50% BCI cotton - using polyester fibers from woven, knit and nonwoven fabric scraps and fillers discarded by clothing manufacturers in the city of Ibitinga (São Paulo, Brazil), combined with virgin BCI cotton fibers and recycled polyester from PET bottles. Defibration was the chosen recycling method for this purpose. The selected fibers were transformed into yarns by the conventional ring spinning process. Knitted fabrics were produced on a small diameter circular machine. The study made evident that there is feasibility in the production of fabrics using the selected resources as raw materials.
