The most widely recycled plastic in the world is recycled polyethylene terephthalate (rPET). To minimize the environmental related issues associated with synthetic fibers, several researchers have explored the potential use of recycled polyester fibers in developing various technical textile products. This study aims to develop needle-punched nonwoven fabrics from recycled polyester fibers and investigate its suitability in oil spill cleanup process.

According to Box and Behnken factorial design, 15 different needle-punched nonwoven fabrics from recycled polyester fibers were prepared by changing the parameters, namely, needle punch density, needle penetration depth and fabric areal weight. Several featured parameters such as oil sorption, oil retention, oil sorption kinetics, wettability and reusability performance were systematically elucidated.

The maximum oil sorption of recycled nonwoven polyester is found to be 24.85 g/g and 20.58 g/g for crude oil and vegetable oil, respectively. The oil retention is about 93%–96% in case of crude oil, whereas 87%–91% in case of vegetable oil. Recycled polyester nonwoven possesses good hydrophobic–oleophilic properties with static contact angle of 138° against water, whereas 0° against crude oil and vegetable oil. The reusability test results indicate that recycled polyester nonwoven fabric can be used several times because of its reusability features.

There is no detailed study on the oil sorption features of needle-punched nonwoven fabrics developed from recycled polyester fibers. This study is expected to help in developing fabrics for oil spill cleanups.

The purpose of this paper is to study the non-isothermal degradation kinetics of recycled polybutylene terephthalate, polytrimethylene terephthalate and polyethylene terephthalate using thermogravimetric analysis (TGA) in a nitrogen atmosphere.

To achieve this goal, the author utilized standard kinetic models, such as Coats-Redfern and Kissinger equations, for analysis of the TGA data.

When applied to the TGA data, the Kissinger model resulted in a coefficient of determination (R2) value greater than 0.99.

This study describes the maiden application of the Kissinger model to obtain the pre-exponential factor (A) and activation energy (E) for different polyester systems used in the textile industry.

Introduction: Sustainable marketing practices foster a company and its stakeholders’ environmental, social, and economic well-being while promoting products and services. An integrated approach to sustainability recognises these three interdependent pillars, seeking to unite together. Investing in renewable energy has triple-bottom-line benefits – reducing greenhouse gas emissions, creating jobs, and promoting economic growth. Sustainable marketing practices can be a win-win for companies and the environment.

Need of the Study: Studying and understanding the sustainable development goals (SDGs) are crucial for India and worldwide. Sustainable marketing is becoming increasingly important for companies as they seek to meet the growing demand for sustainable products and services. Sustainable marketing practices can help businesses reduce environmental impact, promoting eco-friendly products and services.

Purpose of the Study: The study focused on achieving the SDGs requires addressing all three pillars of sustainability together. The study explored the different sustainable marketing practices that companies adopt worldwide, how they contribute to environmental, social and economic stability, the benefits of such practices, and the challenges companies face in implementing them.

Methodology: The study is based on secondary data – 10 companies, out of which 5 brands are among the top 10 brands (Souromi, 2023) and 5 are within the top 20 international sustainable brands (Fashinza, 2020) belonging to the textile industry worldwide, were chosen and their sustainable marketing practices were identified and analysed.

Findings: The study highlights standard sustainable marketing practices adopted by different companies worldwide in the textile industry, exploring the contribution of sustainable marketing practices in achieving SDGs.

Sports fashion is marketed showing happiness, physical performance and self-care. Thus, sports fashion brands should see a good fit with sustainability: future orientation, self-care, care for others and going out for a physical experience, oftentimes in nature. On the other hand, sports fashion is regularly made of non-sustainable materials and produced under difficult work conditions. This paper aims to discuss the aforementioned issues.

The paper at hand seeks to investigate sports brands' approach to sustainability by examining their product portfolio and their annual report data, analyzing their status quo and sustainability strategy. A content analysis is conducted employing the brands' annual reports and their online shops as data sources to assess their status quo in terms of sustainability as well as future plans.

Results show that on the ecological side, brands unanimously focus on carbon reduction, organic cotton, recycled polyester, circularity-ready business model innovation and water and toxic waste management. The social aspect may be divided into the focal brand and the supply chain, including similar measures: equality and diversity, the promotion of ethnic and cultural minorities and increased safety and health for workers.

The paper derives development opportunities and pitfalls for sports fashion brands.

The purpose of this paper is to compare the bursting strength, bursting distension, air permeability and wale wise wicking rate properties of recycled polyester (r-PET) and virgin polyester (v-PET) raw materials from which single jersey knitted fabric samples are manufactured. Meanwhile, numerical optimization method was used in predetermined parameters to determine the optimum r-PET and v-PET blend ratio and yarn manufacturing technology. In the optimization analysis, the average values of the important yarn and fabric properties inspected were taken as a target according to the 50 percent proportion of r-PET and v-PET fiber for both compact and ring yarn manufacturing technology.

To encourage the use of value-added textile products produced from recycling PET bottle with the focus of social responsibility is a condition that should be evaluated within the scope of waste management. The recycling of PET bottles and finding new opportunities for the uses in different field are crucial for both contributing environmental economy and conserving natural energy resources. The most important alternative ways is to use the r-PET fiber from recycling PET bottle in textile industry. In this study, 19.7 tex r-PET/cotton and v-PET/cotton-blended compact and ring spun yarns were produced at different blending ratios at the same production parameters.

Results showed that blend type, blend ratio and yarn manufacturing technology have statistical significance effect on bursting strength and air permeability. Besides, it was found that blend type has no significance on wale wise wicking rate unlike other parameters. Optimization analysis indicated that single jersey knitted fabric with v-PET/CO 58.62/41.38 percent compact yarn had higher desirability with the value of 0.72.

At the present time, r-PET fiber is blended in small amount (approximately 5–15 percent blend ratio) with both cotton and polyester together. In addition, it is possible using different fiber blend types instead of cotton and polyester according to the usage area. The most important question is to determine the amount of r-PET proportion. In other words, both optimum yarn/fabric quality parameters should be ensured and at the same time life cycle of the apparels should not be short when the optimum r-PET proportion is taken into consideration.

Microfiber is one of the major sources of microplastic emission into the environment. In recent times, research on microfiber has gained momentum, and research across different disciplines was performed. However, no complete study was performed from the viewpoint of textiles to analyse the microfiber shedding behaviour by relating the properties textiles. The purpose of this paper is to analyse the microfiber shedding behaviour in textiles.

Articles on the microfiber shedding across different disciplines were collected and analysed systematically to identify the influencing factor. The influence of laundry parameters is found to be majorly discussed section, yet very few research data is found on the effect of yarn and fabric properties on the microfiber shedding.

Most of the articles listed laundry detergent addition, higher temperature, use of softeners, type of washing machines used and amount of liquid used as the major factors influencing the fiber shedding. Concerning the fiber and yarn characteristics, yarn twist, fiber type (staple/filament), method of production, fabric structure and specific density are reported as influencing factors. Some articles highlighted the influence of ageing of textiles on the fiber shedding.

The review identified the research gap in the textile sector and reports that so far, no research performed on microfiber shedding with the textile parameters. The review further urges the importance of research works to be performed in the textile by considering the fabric and yarn properties.

Wool fiber is accepted as one of the natural and renewable sources and has been used in the apparel and textile industry since ancient times. However, wool fiber has the highest global warming potential value among conventional fibres due to its high land use and high methane gas generation. This study aimed to recycle the wool fabric wastes and also to create a mini eco-collection by using the produced yarns.

This manuscript aimed to evaluate the fabric wastes of a woolen fabric producer company. Fabric wastes were opened with two different opening systems and fiber properties were determined. First, conventional ring yarns were produced in the company’s own spinning mill by mixing the opened fibres with the long fiber wastes of the company. In addition, opening wastes were mixed with different fibres (polyester, long wool waste, and Tencel fibres) between 25% and 70% in the short-staple yarn spinning mill and used in the production of conventional ring and OE-rotor yarns. Most of the yarns contained waste fibres at 50%. Recycled and virgin yarns were used as a weft and warp yarn and a total of 270 woven fabric samples were obtained and fabric properties were examined. Also, a fabric collection was created. A life cycle assessment (LCA) was made for one of the selected yarns.

At the end of the study, it was determined that it was possible to produce yarn and fabric samples from fiber blends containing high waste fiber ratios beyond 50%. All the woven fabric samples produced from conventional ring and OE-rotor yarns gave higher breaking, tearing and stitch slip strength values in the weft and warp direction than limit quality values of the company. In addition, abrasion resistance and WIRA steam stability properties of the fabric samples were also sufficient. Environmental analysis of the recycling of the wastes showed a possible decrease of about 9940034.3 kg CO2e per year in the global warming potential. In addition, fiber raw material expenses reduced yarn production cost about 50% in case of opened fabric waste usage. However, due to insufficient pilling resistance results, it was decided to evaluate the woven fabrics for the product groups such as shawls and blankets, where pilling resistance is less sought.

The original aspects of the article can be summarized under two headings. First, there are limited studies on the evaluation of wool wastes compared to cotton and polyester fibres and the number of samples examined was limited. However, this study was quite comprehensive in terms of opening type (rag and tearing), spinning systems (long and short spinning processes), fiber blends (waste 100% and blends with polyester, long wool waste and Tencel fibres) and yarn counts (coarser and finer). Recycled and virgin yarns were used as a weft and warp yarn and a total of 270 woven fabric samples were obtained using different colour combinations and weave types. All processes from fabric waste to product production were followed and evaluated. Life cycle assessment (LCA) and cost analysis was also done. The second unique aspect is that the problem of a real wool company was handled by taking the waste of the woolen company and a collection was created for the customer group of the company. Production was made under real production conditions. Therefore, this study will provide important findings to the research field about recycling, sustainability etc.

Sustainable manufacturing is gaining prominence in light of the rising environmental and social concerns worldwide. One major task to enhance manufacturing sustainability is assessment of the current state of sustainability of a manufacturing firm. This paper reviews the existing sustainability assessment approaches applicable for manufacturing firms and observes that most of these approaches are not easy to apply for reasons such as high amount of skill, data and time requirement. Towards bridging this gap, this study proposes a sustainability assessment approach.

The assessment approach proposed in the paper uses a predefined list of potential sustainable manufacturing practices (SMPs) covering the primary and support activity domains of a manufacturing firm's value chain. It proposes a method to assess the extent of implementation of SMPs and identify associated drivers and barriers for each SMP area/category along the value chain of a firm as well as at overall firm level. A case study from textile industry is presented to demonstrate the utility of this approach.

The sustainability assessment approach adopted in this study uses less time and skills as well as ensures comprehensive coverage of SMPs. It provided valuable information to the management of the case company on how sustainable their practices are and why?

The study highlights the importance of sustainability assessment at SMP area/category level as well as explores practice area/category specific drivers and barriers. It provides a useful approach for a quick assessment of the current state of sustainability in manufacturing firms.

Forward and reverse supply chains form a “closed loop” when managed in a coordinated way and this “cradle to cradle” responsibility has strong relevance to addressing environmental sustainability in global supply chains. The extensive outsourcing of manufacturing has created highly fragmented supply chains, which is strongly evidenced within the UK clothing industry, and it presents major environmental challenges, particularly around waste and resource use. The purpose of this paper is to investigate how a closed loop supply chain (CLSC) can be successfully developed to address environmental sustainability.

The natural resource-based view (NRBV) acknowledges the importance of a firm’s tangible and intangible resources, as well as socially complex relationships, and provides three path-dependent strategies for achieving environmentally based competitive advantage. Via an in-depth case study of the UK-based clothing firm, the NRBV is employed as a framework for understanding the processes that a focal firm needs to engage in to develop a CLSC, and the contribution that is made by its resources and supplier relationships.

The findings illustrate the key importance of strategic resources and shared vision and principles between the focal firm and its suppliers, in order to progress from a more reactive pollution prevention strategy to a fully embedded CLSC response to environmental sustainability. The case study highlights the need to extend the current CLSC model to integrate the design function and end customer; the design function ensures that appropriate environmental practices can be implemented, and customers represent a key stakeholder as they enable the reverse flows required to maximise value and minimise waste.

The NRBV and its three path-dependent strategies are an established framework for understanding environmentally based competitive advantage, but has not previously been explicitly employed to investigate CLSCs. This research, therefore, provides valuable insight into the applicability of this model in the supply chain field, and the key role of tangible and intangible resources and socially complex supplier relationships in developing and achieving a CLSC.
