It was aimed to determine the specific resource use and reduction potential profiles in various textile sub-sectors (cotton woven fabric dyeing-finishing, wool woven fabric dyeing-finishing, synthetic woven fabric dyeing-finishing, cotton knitted fabric, synthetic knit fabric dyeing-finishing, non-woven fabric, dyeing-finishing of knitted fabric). The main focus was to elucidate opportunities for sustainability in terms of decreasing resource utilization in the textile sector. On-site surveys and detailed data collection studies were carried out at 150 textile facilities. Average specific values for water, auxiliary chemicals, dyestuff, electricity, and steam consumptions, and related reduction potentials were calculated and compared within facilities and sub-sectors. The minimum specific resource consumption values reported in the Best Available Techniques Reference Document (BREF) for the textile industry and data of similar facilities from the literature were evaluated and used. A detailed environmental performance profile of the Turkish textile sector in terms of resource usage and reduction potential was generated. The highest specific water consumption was found in the wool-woven fabric sub-sector (345 ± 262 L/kg product). Although the specific auxiliary chemical consumption shows similarities within sub-sectors, the highest specific auxiliary chemical consumption (397 ± 237 g/kg product) was found in the synthetic woven fabric sub-sector. The sub-sector with the highest specific dyestuff consumption (30 ± 13 g/kg product) was the cotton knitted fabric sub-sector. The wool woven fabric industry had the highest specific electricity (7 ± 5.3 kWh/kg product) and steam (20 ± 11 kg steam/kg product) consumption. In addition, for all the studied sub-sectors country-wide, the lowest and highest reduction potentials in resource uses were 18 ± 15% and 73 ± 13%, respectively, suggesting a need for major full-scale implementations of cleaner production for enhancing sustainability in the textile industry.

This paper discusses two major issues: (i) understanding the influence of the solvent used for fibre processing to obtain flame-retardant chicken feathers, and (ii) establishing the importance of the fibre–matrix blending temperature before composite manufacturing. Three temperature profiles for the extrusion die have been taken into consideration: a low-temperature profile (40 °C) (LT-FRCF), a medium-temperature profile (120 °C) (MT-FRCF), and a high-temperature profile (200 °C) (HT-FRCF). Due to better mixing, the tensile strengths for the medium- and high-temperature profile specimens improved by approximately 44% and 83%, respectively. The cone calorimeter results for the samples with water as the solvent for the feather modification showed a 22% reduction in the peak heat release rate compared to those of the samples with ethanol as the fibre treatment solvent, inferring the importance of the solvent used for the processing and making the process more sustainable with a lower water footprint. The research findings provide clear evidence of how the mixing (extrusion) temperature and choice of solvent for modifying chicken feather fibres affect the composites’ mechanical and flame-retardant properties. These insights contribute to our understanding of how keratinous fibres can effectively serve as flame-retardant reinforcements in polymeric composites.

“…Natural fibers, such as wool, consume, for their processing, more water than do synthetic fibers. The water consumption for wool fabric is 200-300 kg/kg, less than for cotton (250-350 kg/kg), but more than the amount used for synthetic polyester (100-200 kg/kg) [29].…”

Eco-Friendly Processing of Wool and Sustainable Valorization of This Natural Bioresource

The environmental invasion of plastic waste leads to, among other things, a reassessment of natural fibers. Environmental pollution has shown the importance of the degradability, among other properties, of the raw materials used by the textile industry or other industrial fields. Wool seems to be a better raw material than the polymers that generate large quantities of micro- and nano-plastics, polluting the soil, water, and air. However, the usual processing of raw wool involves a number of chemically very polluting treatments. Thus, sustainable procedures for making wool processing environmentally friendly have been considered, leading to the reappraisal of wool as a suitable raw material. Besides their applications for textile products (including smart textiles), new directions for the valorization of this natural material have been developed. According to the recent literature, wool may be successfully used as a thermal and phonic insulator, fertilizer, or component for industrial devices, or in medical applications, etc. In addition, the wool protein α-keratin may be extracted and used for new biomaterials with many practical applications in various fields. This review makes a survey of the recent data in the literature concerning wool production, processing, and applications, emphasizing the environmental aspects and pointing to solutions generating sustainable development.
