Fibre continued organic

While the global organic fibre market is now worth around US 800 million , conventional cotton farmers across the world continue to use some US 2 billion of chemicals per year, within which at least US 819 million are classified as hazardous , and cause substantial damage to the well-being of developing world communities and their environment. 

Research into controlled-release antimicrobials continues with organo-silver compounds and silver zeolites, which are promising candidates for textile finishes. Silver ions, for example, incorporated in glass ceramic, have a very low toxicity profile and excellent heat stability. These principles are also used for fibre modification, an alternative to the antimicrobial finishes with high permanence. In recent years a variety of antimicrobial modified fibres have been developed, including polyester, nylon, polypropylene and acrylic types. An example of these fibre modifications is the incorporation of 0.5-2 % of organic nitro compounds...
