This article presents a comprehensive analysis of key quality indicators for spun yarns, focusing on yarns with a linear density of T=20 (Ne=30) tex produced on both simple and compact ring spinning machines. Through the utilization of optical instrumentation, various parameters including relative breaking strength (Rkm), strength, elongation at break (E %), and hairiness (H %) were meticulously examined to evaluate yarn quality. The study delves into the assessment of yarn unevenness (CV %) as a crucial quality metric, aiming to provide insights into the deformation characteristics of spun yarns. By employing advanced optical techniques, such as high-resolution imaging and precise measurements, the deformation behaviour of yarns under different spinning conditions is elucidated. The findings shed light on the influence of spinning machine type on yarn quality parameters, revealing nuanced differences in strength, elongation, and hairiness between simple and compact spinning processes. Additionally, the analysis highlights the correlation between yarn deformation and overall yarn quality, emphasizing the significance of understanding deformation mechanisms in optimizing textile manufacturing processes. Through a rigorous examination of these quality indicators, this research contributes valuable insights into the intricate dynamics of spun yarn deformation and its implications for textile production. The utilization of optical instrumentation offers a novel approach to visualize and quantify yarn deformation, providing a deeper understanding of the factors influencing yarn quality and performance in industrial settings.

This paper explores the potential of solar desalination as a sustainable solution to meet household water needs in regions facing freshwater scarcity. With a focus on decentralized systems, the study examines the design, operation, and feasibility of small-scale solar desalination plants for residential use. Solar desalination harnesses renewable energy from the sun to convert seawater or brackish water into potable water, offering an environmentally friendly alternative to traditional desalination methods. By integrating solar technologies with innovative desalination processes, households can gain access to clean and safe drinking water while reducing reliance on centralized water supply systems. This review discusses the principles, benefits, challenges, and future prospects of solar desalination at the household level, highlighting its potential to address water security challenges and enhance resilience in water-stressed communities.
