Análise técnica do uso de resíduos de poli (tereftalato de etileno) (PET) na indústria têxtil

Abstract

The increase in the volume of industrial wastes and continuous production of solid waste of various kinds cause many environmental concerns. In this context, the disposal of packaging and bottles of poly(ethylene terephthalate) (PET) has become a major problem because of the little attention given to the final destination. Therefore, this research proposes a technical analysis of the use of PET waste, from primary recycling, as feedstock for textile industry. Yarns of recycled PET were compared with commercial polyester yarns through of various analysis, such as, tensile test and solidification color analysis. At the same time, scanning electron microscopy (SEM) was used to investigate the morphology of the yarns and better interpretation of results. It might be noted that yarns of PET recycled have satisfactory performance, although tensile strength and solidity color to light are inferior to conventional polyester yarns.
