SUMMARY:

The textile and clothing industry, in addition to being one of the oldest and largest in the world, also stands out as one of the most profitable sectors. According to UNECE (2018), the sector showed one of the highest growth rates at the beginning of the 21st century. However, this growth has also made it one of the biggest global polluters, as the foundations of the industry are based on unsustainable environmental production and consumption practices. These practices directly and significantly impact the triple planetary crisis, which includes climate change, loss of nature and biodiversity, and, finally, pollution and waste.Textile waste from the fashion industry is a direct consequence of the linear economic production model, which promotes a cycle focused on extracting from nature, transforming into products, and discarding. This system is driven by fast fashion, the predominant model in the fashion industry, characterized by the rapid and large-scale production of clothing inspired by the latest trends. Due to the fleeting nature of fashion trends, consumers are encouraged to purchase frequently and in large quantities, resulting in an accelerated cycle of production and disposal. This production model is based on the use of cheap labor and low-quality raw materials to reduce production costs and maximize the profits of major department store companies.This research aims to present a technological alternative for reverse logistics by considering the socio-environmental and industrial relevance in an attempt to reintroduce this pre-consumer cotton textile waste into the textile manufacturing chain as a new value-added product. In this context, the present project aims to incorporate the mentioned waste into a polymeric matrix, thus obtaining a composite material for application in the fashion industry. The fabrication of the composite materials was carried out using two phase-inversion techniques: evaporation and immersion precipitation, to analyze which method achieved better physical properties.
