ANALYSIS OF THE MECHANICAL PROPERTIES OF SOME HIGHTECH YARNS WITH DIFFERENT FUNCTIONS

We live in a knowledge-based society, which is facing an increasing impact of science and technology on all aspects of life through products, services and consumer needs. In the future, society will be oriented towards the individual and his needs, which will be more and more complex and varied. The present paper comparatively presents a series of variants of cotton fibre yarns: made of blended cotton fibres with ultra-high molecular weight polyethylene fibres; yarns of cotton fibres blended with regenerated cellulose fibres, that were functionalized with Ag ions and yarns obtained from fibre blends of recycled organic cotton, virgin cotton with recovered cotton fibres in order to observe their mechanical potential. The built-in functionalities allow their use in areas such as healthcare and hygiene, sports and leisure activities. The recovery of textile waste in a circular approach and the transition to a circular economy is an important direction for research. The repercussions that the consumption of raw materials in the textile industry has, on the environment, as well as on sustainability, determine us to reason in a judicious way when we select the different materials that we use in making the products.
