Ecoprint: desenvolvimento de estampas em tecido 100% algodão usando aplicação de folhas e flores naturais

Abstract

The growing concern about the environmental impacts caused by the textile industry has driven the development of sustainable alternatives to conventional dyeing and printing methods. In this context, this study aimed to develop prints on 100% cotton fabrics using the ecoprint technique, through the application of natural leaves and flowers collected in the city of Apucarana-PR. The methodology was based on exploratory research with an experimental and bibliographic approach, and involved the collection and selection of plant species, fabric preparation using natural mordants (tannin and a mixture of reagents), and the application of steam printing with exposure times of 30, 60, and 90 minutes. The samples were evaluated both visually and through spectrophotometric analysis using the CIELAB system. The results showed that the tannin method provided more intense, well-defined prints with greater color depth, especially after 90 minutes of steam exposure. The most prominent species were onion peel and cosmos flower, both demonstrating high dyeing potential. It was concluded that ecoprint applied to cotton is a viable and environmentally friendly technique, capable of producing aesthetic patterns with reduced ecological impact, in alignment with sustainability principles and the United Nations Sustainable Development Goals (SDGs).
