Assessing the Mechanical Properties of Low-Quality Sheep Wool Yarn

The current need to address environmental challenge s by Embracing new sustainable practices has attracted interest in waste management and valorization . The agriculture sector generates a large amount of wastes and by-products that are often not adequately valorized, leading to significant environmental impacts due to inadequate management and illegal disposal practices. Among these waste materials, one notable example is “low-quality sheep's wool,” typically deemed unsuitable for textile industry. However, owing to its unique mechanical, thermal, and acoustic properties, along with its renewable and recyclable nature, researchers have recently begun recognizing its potential applications. This study aims to explore the use of wool fiber within the context of sustainable construction thereby promoting environmentally friendly practices and facilitating the transition towards a circular economy. The main objective of this study was to perform tailored analyses of the mechanical properties of a yarn obtained using low-quality wool. To achieve this, 5 kg of raw wool were processed for obtaining a yarn with across-section of 3.5 mm and a yarn count of 3/500.Whilefurther research is necessary to determine how this type of wool can be utilized to manufacture building components, the findings of this study represent a significant step towards the development of eco-sustainable building materials.
