Abstract: In the present era of environmental consciousness, sustainable materials play a vital role in protecting public health and environment. The eco-problems in textile industry occur during some production processes and are carried forward right to the finished product. Controlling pollution is as vital as making a product free from the toxic effect. There is a need to produce the material which is eco-friendly. So, the materials can be considered ‘environmentally friendly for a variety of reasons’. Concerns for the environment and consumer demand are driving research into environmentally friendly fibres as replacements for part of the 38 million tonnes of synthetic fibres produced annually. The main problems with synthetic fibres are that they are non-biodegradable. In last few decades, the textile industry has witnessed introduction of many new fibres in the market. Recently, environmental concerns and the growing global waste problem have spurred much research into the development of bio-based materials and motivated governments to increase the legislation pressure. Many clothing companies are focussing on use of sustainable fibres for manufacturing textiles and garments. These fibres are eco-friendly and are extracted or manufactured from bio-resources. Many innovations have been reported in recent years regarding the sustainability of these fibres. In this paper production of some regenerated sustainable fibres from bio-resources such as Viscose rayon, Lyocell fibres, Cupro fibres, Casein fibres, Groundnut protein fibres, Zein fibres, Soya bean fibres, Silicate fibres and Alginate fibres have been discussed.
