Body Text: <p>DuPont Sorona&reg; is a partially bio based polymer (37%) derived from annually renewable plant sugar and oil based TPA. </p> <p>A life cycle assessment published by DuPont indicates that the production of DuPont Sorona&reg; fibres has a 60% lower carbon footprint than nylon 6,6, an alternative polymer [1,2].* </p> <font size="2">* Note that this is a comparison of polymers at the factory gate. The overall environmental implications of producing clothing from each material will depend on subsequent processing, use and disposal methods.</font>

Body Text: <p>Man made cellulose fibres are manufactured from plant based raw materials. These currently span a variety of different end fibres that have various performance attributes and have been produced through various processing methods.</p> <p>One man made cellulose fibre that has proven resource savings is <a href="https://www.lenzing.com/products/tencel-tm/" target="_blank">TENCEL&reg;.</a> TENCEL&reg; is the brand name used by Lenzing Fibers for their version of lyocell. Production is based on a revolutionary solvent spinning process. The unique closed-loop production process was the result of new demands placed on manufacturers for environmentally responsible products that utilised renewable resources as their raw materials.<p> <p>It is the direct dissolution of the cellulose in an organic solvent without the formation of an intermediate compound that differentiates lyocell from other cellulosic fibres such as viscose. The closed-loop manufacturing process recovers >99.7% of the solvent. The solvent itself is non-toxic and all the effluent produced is non-hazardous. TENCEL&reg; has all the benefits of being a cellulosic fibre, in that it is fully biodegradable and absorbent. It has high strength in both the wet and dry state and being a staple fibre it blends well with all other fibres types.</p>

Body Text: <p>A peer-reviewed life cycle assessment from 2010 [1] analysed the environmental implications of five man-made cellulose fibres produced by Lenzing in either Asia or Austria. The carbon footprint findings are shown on the figure to the left. The figure includes a new (2012) version of Tencel that was due to be produced with energy recovered from waste, a lower carbon form of energy.</p> <p>The study concluded that modern man-made cellulose fibres have a “clear potential” to reduce environmental impacts compared to other fibres.</p>

Body Text: <p>Archroma Advanced Denim, reduces resource use in two ways:</p> <p><b>Denim Production</b><br> Two new modifications have been developed by Clariant to reduce process steps within denim colouration, whilst at the same time widening the colour potential for denim. Archroma's Denim-Ox process reduces the 10-12 box stages prior to sizing, down to only 4 boxes, whilst their Pad/ Sizing - Ox process reduces this further to just 1 box.</p> <p><b>Indigo - Free</b><br> In general all jeans are post-washed/treated for aesthetic reasons. One of the most popular post-washings is bleach, which uses chlorine for obtaining a paler blue. In the case of Advanced Denim, the use of Diresul RDT Indicolos instead of Indigo, allows for a more efficient dyeing process but also the possibility to use a safer and more environmental friendly agent to obtain bleached looks.</p>
