The textile industry is considered the most ecologically harmful industry due to toxins released during dyeing and bleaching processes. This has led to a need for more eco-friendly or "green" textiles made from organic and recycled materials. Eco-textiles, also called ecotech or oekotech textiles, refer to textile products produced and processed using environmentally sustainable methods. Examples of eco-friendly fabrics include organic cotton, hemp, bamboo, and recycled polyester. The market for technical textiles used in environmental engineering applications is growing due to increased awareness of sustainability issues and regulations regarding waste management.
