As contrast to cotton and wool produced in traditional methods, hemp and bamboo are natural fi bers that do not create environmental problems for two reasons: the fi rst is due to extraordinary productivity, easy cultivation, and high pest tolerance, requiring little or non-agrochemical application, such as pesticides and fertilizers, and second, the deep roots of these materials bind and enrich the soil (Greenchoices N.D.). Bamboo, especially, promotes a range of technical performance capabilities with its natural characteristics and properties (e.g., hypoallergenic, absorbent, fast drying, and antimicrobial) (Greenchoices N.D.). In addition to hemp and bamboo, linen made from fl ax is also an eco-friendly material that consumes few chemical fertilizers and fewer pesticides than cotton (Greenchoices N.D.). 4.1.2 Alternative Materials for Environmental Sustainability In today s textile industry, to reduce the natural resource consumption and green- house gas emission, environmentally sustainable fi ber production methods have become available as alternatives to traditional ones in the following textile cate- gories: synthetic fi ber (e.g., recycled polyester), regenerated cellulose fi bers (e.g., Tencel ® , Modal ® , and lyocell), and natural fi bers (e.g., organic cotton and wool). Recycled polyester (rPET) Recycled polyester (rPET) has been suggested as an eco-friendly alternative to polyester for two reasons: for one, rPET production requires approximately 33 53 % less energy compared to virgin polyester, and two, rPET generates 54.6 % fewer CO 2 emissions than virgin polyester (Libolon N.D.). For instance, since 1993, Patagonia has produced clothing (e.g., Capilene ® base layer, fl eece, and Fig. 4 Greenhouse gas impacts of annual cotton production in the global textile industry (Kirchain et al. 2015 ) Environmental Sustainability in the Textile Industry 29

board short shell jacket) using recycled polyester obtained from recyclable materials such as plastic soda bottles, unusable manufacturing waste, and used garments (Patagonia N.D.b). The use of recycled polyester by Patagonia is an example of a best practice for environmentally conscious manufacturing in the textile industry, providing multiple bene fi ts to the environment and society, such as reducing pet- roleum usage, increasing land fi ll life, decreasing greenhouse gas emissions, and promoting polyester-made clothing recycling streams (Patagonia N.D.b). Despite the advantages of rPET, it still creates environmental issues, due to its approxi- mately 30 % greater use of chemical bleaching solutions and water and energy usage for redyeing processes as compared to virgin polyester production (Oecotextiles 2010 ). Modi fi ed regenerated cellulose fi bers To reduce the negative impacts of a traditional viscose rayon manufacturing pro- cess, the Austrian textile company Lenzing developed Tencel ® and Modal ® , innovated types of rayon. Tencel ® and Modal ® adopt more eco-friendly manu- facturing processes with the use of non-toxic solvent spinning, which are capable of

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
