- Circular economy: Proposal for sustainable sneaker production in a small footwear companyPublication . Sanches, Regina Aparecida; Duarte, Adriana Yumi Sato; Mendes, Francisca D.; IPCB. ESARTAbstract: A solution for the destination of discarded textile scraps from clothing companies is textile shoddy. The process is known as textile recycling. The shoddy fibers are obtained from the processing of residual materials and reinserted into the textile chain to produce new fabrics through circular economy strategies. In this context, the main objective of this article is to present a proposal to produce sustainable sneakers for small footwear companies. To produce the yarns, shoddy fibers originating from garment scraps discarded by industries in the city of Ibitinga (SP, Brazil) were used. Textile materials discarded by the clothing manufacturers with a 100% polyester composition were selected; the fabric scraps were shredded and mixed with recycled polyester fibers (PET) to produce the yarns: 50% shoddy fibers / 50% recycled polyester from PET bottles. The yarns were produced on ring spinning frames and the uppers on rectilinear knitting machines. The produced articles showed that there is technical viability to produce seamless knitted uppers using shoddy fibers as raw materials.
