cotton, naturally colored cotton, lyocell, corn, soya bean, recycled polyester, and some others, as listed in Table 1 (Jain and Easter 2010 ). With the increase in consumer interest and the establishment of third-party certi fi cation systems, the textile industry has emphasized the production of sus- tainable fi bers and the search for newer alternatives. Some successful examples are Tencel, recycled polyester, recycled and organic cotton, and bamboo. However, the sustainability and eco-friendliness depend critically on how the fi ber is subse- quently processed. The careful selection of dyes and chemicals through accurate and reliable information provided by reputed suppliers enables processors to match a customer s RSL criteria. Because of a lack of clear information and the absence of an inter- nationally agreed-upon standard for a de fi nition of eco-friendly dyes, various myths and misinformation have emerged around dyestuffs. In summary, a sustainable approach covers the following points: Minimum use of resources (water and energy) Minimum chemical consumption Minimum pollution load Elimination of toxic chemicals from the supply chain. Therefore, sustainable textiles or apparels are, Safe for humans and the physical environment Made from renewable materials Produced while making the most ef fi cient use of resources, such as water and energy Manufactured by people employed in decent working environments Capable of being washed at low temperatures using environmentally friendly laundering agents Capable of being returned safely to the environment at the end of their useful life (Performance Apparel Markets 2009 ). In terms of life cycle assessment, sustainable textiles are manufactured and used in sustainable ways without using restricted substances and can be disposed of sustainably after use. To minimize the usage, it is important to measure the inputs. To eliminate the most harmful chemicals, it is important to know and understand what is being used.

Uncontrolled or unknown inputs lead to the unmanaged use of resources and uncontrolled outputs. The measurement and control of these inputs and outputs can lead to the following: Improved resource productivity Improved eco-ef fi ciency Improved cost ef fi ciency Improved customer satisfaction Improved brand reputation 4 Restricted Substances The relocation of production due to globalization has created additional levels of complexity for sustainable textile production because different nations have dif- ferent environmental laws or even none at all. To secure a clean production by manufacturers, trade and brands around the world refer to the RSL. The number of demanding and critical consumers requesting transparent value chains and high- quality, harmless, and environmentally safe products is constantly growing. This is

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
