Comparison of Physical Properties of Fabrics Woven from Open-End and Ring Spun Yarns

It is well established that open-end yarns are different from ring yarns; in particular OE yarns are weaker and more bulky in spite of the higher twist levels used. The introduction of these yarns into woven fabric affects the structure and the characteristics of the fabrics. The fabric structure traps non-load bearing fibers and thus gives increases in fabric strength and decreases in fabric extensibility. Crimp levels are altered which affect the initial modulus and the breaking extension of the fabric. This and the different yarn characteristics lead to considerable difference in tear strength. In the cases, of both ring and OE fabrics, the looser the structure, the worse the pilling performance and the better the tear performance. Compromises have to be made according to end-use. The changes in structure alter the topography of the fabric which affects the wear behavior. The changes in structure also affect the crease resistance and flexural rigidity characteristics of the fabrics. Thus the differences in the yarn structure play a distinct part in determining the final nature of the fabric.
