Bending rigidity of yarns using beam method on a two-support configuration

This paper reports a simple, quick and reasonably accurate approach for measuring the bending rigidity of yarns. The beam method has been adapted and applied using a bending frame that has a fixed support and a simple support. The yarns are left to bend under the effect of their own weight. The accuracy and the precision of that bending frame are assessed over the time using an isotropic material and then compared against the ring-loop method and the KES-FB-2 pure bending tester. The findings show that the precision of this bending frame is acceptable. However, this bending frame gives at least 1.6 times greater values of bending rigidity than the KES-FB-2 pure bending tester, though the relationship between these two methods is linear and significant. Moreover, the spun yarns appear to have high levels of variability of the bending rigidity. This study is important as it overcomes the challenges faced while using other methods to measure the bending rigidity of yarn. It also provides a comprehensive account of the variation in this property. Further, it gives an indication of the highly non-uniform structure of spun yarns and the impact of yarn defects on the bending properties of yarns

Optimizing Reliability of Digital Inclinometer and Flexicurve Ruler Measures of Spine Curvatures in Postmenopausal Women with Osteoporosis of the Spine: An Illustration of the Use of Generalizability Theory

The study illustrates the application of generalizability theory (G-theory) to identify measurement protocols that optimize reliability of two clinical methods for assessing spine curvatures in women with osteoporosis. Triplicate measures of spine curvatures were acquired for 9 postmenopausal women with spine osteoporosis by two raters during a single visit using a digital inclinometer and a flexicurve ruler. G-coefficients were estimated using a G-study, and a measurement protocol that optimized inter-rater and inter-trial reliability was identified using follow-up decision studies. The G-theory provides reliability estimates for measurement devices which can be generalized to different clinical contexts and/or measurement designs

Textile Recycling and Recovery::An Eco-friendly Perspective on Textile and Garment Industries Challenges

The world has been facing a growing crisis in textile waste due to global population growth and improved living conditions, combined with a decrease in the life cycles of textile products. Textile recycling is one of the key aspects for reducing the massive waste problem generated by the fashion and textile industries. Despite the need to develop textile waste recycling industries, acceptable practical interim measures still need to be taken. Textile waste can affect people’s lives economically and environmentally. Producing apparel from natural or synthetic origin can produce pollutants and waste at each stage. In this review article, the effects of the fashion and textile industry have been studied from economic and environmental perspectives. The available technologies and methods for waste recovery and recycling at each stage have been studied, and the uses of products after recycling have been systematically investigated. Despite all the progress made in the waste recycling processes of the fashion industry, many deficiencies and challenges still need to be addressed. Among the most critical challenges are the large scale of industries, the problems of collecting and classifying waste materials, and the presence of contaminants including blends and chemicals. There is also need for more awareness among consumers about the importance of fiber-to-fiber recycling processes, because to date the progress in this field is out of proportion to its necessity. Overall, this article is a valuable resource for anyone interested in understanding the current state of recycling and recovery in the textiles, garment, and fashion industries.<br/

The impact of COVID-19 on the mental wellbeing of health and social care workers in Scotland

Background: Recent studies published during the COVID-19 pandemic have reported that the mental wellbeing of health and social care workers (HSCWs) has been adversely impacted. Research has yet to explore what factors may help HSCWs positively adapt in the face of the adversities endured during the pandemic. Methods: The study consisted of a cross-sectional online survey exploring the impact of COVID-19 on the mental wellbeing of HSCWs (n= 1300+). The survey included both closed and open-ended questions exploring COVID-19 perceived risks, stress, burnout and mental wellbeing as well as coping and team resilience. Both quantitative and qualitative content analysis of the online survey data was conducted. Expected results: Data collection began in December 2020 and data collection and analysis is due for completion in June 2021. Preliminary analysis suggested that access to PPE, psychological input and increased perceived team resilience and peer support helped mitigate against the adverse impact that COVID-19 related stressors have on HSCW's mental wellbeing. Visible leadership was also found to be essential in helping staff gain access to current and accurate information on COVID-19 and in helping workers adapt to constant change. Discussion: The implications of these findings are discussed, emphasising the importance of access to PPE as well as peer and team-based support in alleviating the negative impact that COVID-19 has on HSCW's mental wellbeing. The results of this study also highlight the urgency of offering psychological input for HSCWs who need it. The importance of supportive, adaptive and visible leadership is highlighted.
