“… 9 The share of polyester (PET) fiber alone accounts for more than 54% in the global textile industry, 10 which is expected to grow in the coming years. 11 Therefore, PET is considered an important textile fiber, and most of the previous laundering studies primarily focus on PET fabrics.…”

The release of fragmented fibers (FFs), including microplastics from textiles, during their service life is considered an established source of environmental pollution. The yarn structure is identified to affect the amount and length distribution profile of shed FFs from textiles. In the present work, the impact of yarn structures spun from 100% polyester staple fibers, using commercially relevant spun yarn technologies in the textile industry, on the release of FFs from textiles is studied. The bespoke woven fabric samples produced from three types of spun yarns, which include ring, airjet (air vortex) and rotor yarns, were subjected to an accelerated washing process, for up to five washes, to quantify shed FFs and their length distribution profile. The morphological shapes of FF ends associated with the nature of fiber damage were also investigated. The results demonstrated that airjet and rotor yarn structures had released 28% and 33% less mass of FFs, respectively, as compared to the ring yarn structure during the whole washing process. The length distribution profile identified that the ring yarn structure shed longer length FFs as compared to both airjet and rotor ones. The damaged ends highlight the importance of textile manufacturing processes on the generation of FFs. The results of this study give a better understanding of the yarn structural effect of commercially relevant technologies on shedding of FFs, which are released as a pollutant to the environment.

“…The authors pointed out that chemical oxygen demand caused the largest water eutrophication footprint, followed by ammonia nitrogen and 5-day biochemical oxygen demand. 8 Some scholars also accounted for and evaluated the water footprint of alkali reduction, printing and washing processes of polyester printed fabrics based on the water footprint theory, 18 which pointed out that the washing process is a key aspect of water conservation and the alkali reduction process is a key aspect of implementing pollutant reduction and treatment. Down jackets are practical cold-weather garments.…”

Down jackets consume a lot of energy and water, and emit greenhouse gases, wastewater and other pollutants during the life cycle. For example, melt spinning polyester fibre production, spinning, weaving, fabric dyeing and finishing are high-energy consumption processes. Down processing, fabric dyeing and finishing are typical water consumption and wastewater pollutant discharge processes. Carbon and water footprints are practical tools for evaluating the environmental impact of a product in its life cycle. This article quantified and evaluated the carbon and water footprints of the life cycle of 100 down jackets – from raw material production to recycling and disposal without transportation activities. The results showed that the carbon footprint of the 100 down jackets production was 2544.1 kgCO2e with recycling. As for the water footprint, it showed that fabric production had a great impact on water eutrophication and water scarcity. The water scarcity footprint of 100 down jackets production was 27.46 m3H2Ot, respectively. The water eutrophication footprint generated by producing 100 down jackets in new industry was 1.91 kgPO43−eq. The comprehensive assessment of carbon footprint and water footprint with the life cycle assessment polygon method indicated that the raw material production phase of down jackets generated a more significant impact on the environment than the use phase. The impact on the environment during the use phase is primarily the environmental load on water resources.

O aumento das emissões de gases de efeito estufa (GEE) tem intensificado o aquecimento global e evidenciado as mudanças climáticas no cenário nacional e mundial. Nesse contexto, torna-se necessário que sejam utilizadas ferramentas de monitoramento, como forma de conscientização visando à sua redução. Entretanto, esses cálculos são complexos e, para facilitá-los, podem ser utilizadas calculadoras de pegada, que se constituem como importantes ferramentas de comunicação sustentável. Neste estudo, foi utilizada a Calculadora de CO2 da Iniciativa Verde para obter os valores estimados de emissão relacionados a uma escola de ensino fundamental localizada na zona rural do Município de Caruaru, Estado de Pernambuco, Nordeste do Brasil. O plantio de árvores é uma possível alternativa de compensação e, de acordo com os dados da plataforma, pode ser obtido o quantitativo necessário para neutralizar as emissões. Foi realizado o plantio de 17 mudas de espécies endêmicas selecionadas, o que proporciona à escola o patamar de carbono zero.
