The UPC’s INTEXTER has carried out an evaluation to calculate the share of fibers used within the garments which are dumped in textile assortment bins. The examine makes use of an progressive methodology and is due to this fact extra correct than different approaches thus far.

About 550 kg of garments from the Formació i Treball Basis clothes bins have been analyzed within the first examine ever to characterize the fibers that make up T-shirts, shirts, coats, trousers, jackets and different kinds of clothes which are dumped in textile assortment bins.

In line with INTEXTER researchers, of all used garments from the bins, 62% are reusable and 37% are recyclable. The examine concludes that the most typical fiber is cotton, with 50% in recyclable garments and 60% in reusable garments. Polyester follows, with 30% in each varieties. Subsequently, cotton and polyester account for about 80% in recyclable clothes and 88% in reusable clothes.

Acrylic fibers account for a a lot decrease share. The examine reveals a big distinction between recyclable clothes (12.4%) and reusable clothes (3.1%), as a result of clothes produced from these fibers is essentially the most readily deteriorated.

The characterization has been attainable by means of an progressive methodology based mostly on crushing clothes and standardizing the combination by the use of two steps: (1) computerized carding and (2) analyzing the ensuing webs utilizing the standardized chemical methodology. The end result permits for the dedication of the composition of textile merchandise, together with the usual moisture regain of each fiber.

Specializing in cotton and polyester

INTEXTER Director Enric Carrera says, “In mild of the evaluation, we will say that the recycling technique of post-consumer textile waste ought to concentrate on recovering and reusing 80% of the predominant fibers, specifically cotton and polyester.”

The examine additionally consists of an evaluation of the fiber composition of clothes on the web sites of main manufacturers. A complete of 701 clothes had been analyzed, equivalent to the primary 30 objects in six main classes (T-shirts, jumpers, denims, underwear, socks and shirts) at Zara, H&M, C&A and Mango. On this case, the evaluation doesn’t embrace jackets or coats.

The evaluation reveals that 66.8% of clothes include combined fibers, which considerably limits their recycling potential. Solely 37.3% of the clothes studied are 100% made with a single fiber.

As for house textiles, 361 objects had been analyzed, equivalent to the primary 20 objects in 4 main classes (sheets, towels, tablecloths and curtains) at Ikea, Zara Residence, H&M Residence, 10xDIEZ and Carrefour. In contrast to clothes, house textiles are predominantly fabricated from a single materials. The most typical fibers are cotton, polyester, linen, viscose and lyocell, in that order. Sheets and towels are primarily produced from 100% cotton, whereas tablecloths and curtains from 100% polyester, though binary mixtures of cotton and polyester or cotton and linen are additionally used.

Extending the life of clothes

How a lot would we cut back our environmental influence by reusing used clothes? Carrera says, “If we may double the lifespan of clothes, we might be lowering the style trade’s greenhouse gasoline emissions by 44%. Extending the energetic lifetime of clothes by simply 9 months would already cut back carbon, water and waste footprint by 20–30%. A rise of 10% in second hand gross sales may save 3% of carbon emissions and 4% of water, based on information from the report Valuing our garments: the price of U.Okay. style, printed by WRAP in 2017.”

The UPC’s INTEXTER has carried out an intensive bibliographic evaluate of current research on how a lot CO2 is saved by reusing clothes. It has concluded that reusing 1kg of clothes saves 25 kg of CO2, in contrast to EU estimates thus far, which steered solely 3.169 kilos.

How are recycled clothes made? And why is recycling them additional so laborious?
