STUDY OF THE INFLUENCE OF WOOL TYPE USED IN A YARN, IN TERMS OF TENSION
Journal Title: Annals of the University of Oradea. Fascicle of Textiles, Leatherwork - Year 2016, Vol 0, Issue 2
Abstract
The use of yarns for manufacturing textiles is increasing in modern times, and new, better methods for making yarns are employed. Yarns are the elements of which textiles are made. In order to diversify the assortment of textile products, more and more types of yarn are made, called heterogeneous yarns, which are yarns made using different types of fibers or filaments. From a technological standpoint, the purpose of mixing fibers is to seek to improve certain physical and mechanical characteristics such as fineness, strength, uniformity etc., which influence the properties of the textile products. A significant increase in yarn strength is achieved by introducing in a mix of wool fibers a certain percentage of synthetic fibers, such as polyester, which have double or even triple the strength of wool fibers. Synthetic fibers however have the downside of having a low hygroscopicity. For this reason, the yarns commonly used are those which have a a natural component, namely wool. One of the main objectives of mixing is to better use the available raw materials. Thus, from soft yarns one can make soft fabrics and knits, and, with the same quantity of raw material, can obtain a larger surface of fabric or knits, with direct impact on costs. With regard to the quality and properties of the textile products, the decisive element is not only the type of the fiber and the proportion in which it is present in the mix, but, fundamentally, the right choice of characteristics for those components (length, fineness, cross-section).
