재활용 PET 및 PCT 기반의 비건 스웨이드의 그레이 컬러 염색성에 관한 연구

Abstract

As environmental concerns have grown, there is increasing interest in ecofriendly and human-friendly vegan suede as a substitute for natural leather. This study used microfiber vegan suede made from recycled PET and eco-friendly fiber PCT to explore the dyeing of a grey color using disperse dyes, suitable for various products. The results confirmed that the optimal dyeing conditions for grey color on vegan suede are 120 °C for 30 minutes. Additionally, by varying the composition of the reducing agent during the reduction clearing process, it was found that under conditions of 5 g/l of reducing agent, 5 g/l of alkali, and 6 g/l of surfactant, the dry rubbing fastness was rated 4-5, and the wet rubbing fastness was rated 3-4. This represents an improvement of at least one grade in fastness compared to suede without reduction washing, indicating that the reduction washing positively impacts dry rubbing fastness. Ultimately, this study evaluated the influence of the dyeing and reduction washing processes on the fabric's properties, providing foundational data to enhance the practicality of vegan suede.
