The new emerging technology of dyeing; which is really enthusiastic for Indian textile industries. Indian textile processing is one of the highly water-consuming industries. Such technologies have reached the international advanced level and meet the state emission-reduction and energy-saving requirements for environment-protection products and new technologies of the textile industry, producing good economic and social benefits and making a positive contribution to the energy-saving and emission-reduction work. This technology also reduces the effluent load. This new technology is called "AIRDYE".
Keywords: Air Dyeing, Cost Reduction, Energy Saving, Environment Protection, Water Saving.
Introduction
AirDye technology manages the application of color to textiles without the use of water. It was developed and patented by Colorep, a California-based sustainable technology company. Depending on the fabric and type of dyeing, AirDye uses up to 95% less water and up to 86% less energy, contributing 84% less to global warming, according to an independent assessment requested by the company[1]. AirDyed fabrics do not leach colors or fade as easily as vat-dyed fabrics because the dye is actually inside the fibers. The process of making textiles can require several dozen gallons of water for each pound of clothing. The AirDye process employs air instead of water to help the dyes penetrate fibers, a process that uses no water and requires less energy than traditional methods of dyeing; the technology works only on synthetic materials and is currently available only in the United States.
