Environmentally-friendly thermal and acoustic insulation materials from recycled textiles
2019
Abstract Continuing increase in energy consumption and environmental pollution are some of the main challenges of the 21st century. One of the approaches to overcome these challenges is to increase the use of recycled materials and environmentally-friendly approaches to manufacturing. Thermal and acoustic insulation in buildings and transport vehicles from recycled textiles can play an important role in energy savings and reduction of environmental pollution. Textiles contribute a significant amount to the waste stream since most of these valuable fiber products are discarded after use. These discarded but valuable textiles can be recycled to produce several products including thermal and acoustic insulation materials. In this paper, a comprehensive review of the current state of textile waste generation and its environmental effects, and present progress of using industrial and post-consumer recycled textiles in insulation materials is provided. Mechanism of acoustic and thermal insulation materials of textile fibers are also reviewed. Existing research of some textile waste used as building insulation materials, method of conversion of textile waste into building insulation materials, comparative analysis of different insulation materials and life cycle assessment of textile fibers are assessed.
