Waste Management

Ecotextiles: The way forward for sustainable development in by Mohsen Miraftab

By Mohsen Miraftab

A conscientiously selected and edited number of 23 papers from the Ecotextile 2004 convention held on the collage of Bolton, this e-book explores recycling and use of waste as uncooked fabrics in such parts as garments and carpet manufacture.  The papers speak about sustainability and eco-design with issues on greater layout, use of sustainable fibers, and production suggestions. next chapters evaluate sustainable improvement and renewables, together with composites made up of cloth waste. They take on waste administration in components corresponding to dyeing and effluent therapy. the realization assesses novel applied sciences, together with new fibers and completing techniques.

The repolymerized nylon 6 is converted into yarn and tufted into carpet. The carpets obtained from this process are very similar in physical properties to those obtained from virgin caprolactam. The “6ix Again” program of the BASF Corp. has been in operation since 1994. Its process involves collection of used nylon 6 carpet, shredding and separation of face fibers, pelletizing face fiber for depolymerization and chemical distillation to obtain a purified caprolactam monomer, and repolymerization of caprolactam into nylon polymer [19].

Currently in the United States alone, over 2 million tons of postconsumer carpet waste is discarded into landfills each year, and the amount is expected to increase to over 3 million tons by 2012. Very little post-consumer carpet at present is recycled. To establish a sustainable commercial network to recycle fibrous waste, operations based on different technologies must coexist such that different types of materials collected can be recycled to the greatest extent. This paper reviews technologies for carpet waste recycling.

A range of after-treatments to confer additional properties is also available, these include impregnation, coating, infra-red singeing, calendering and lamination, to complete the manufacturing process. To complement the roll goods manufacturing Anglo Felt has developed a significant slitting, sheeting and cut parts converting operation and distribution business in order to provide maximum service for the customer. This versatile operation has provided the possibilities for development of specialist technical products from recycled fibres.
