It is shown that core-spun yarns have improved breaking strength, elongation and elastic recovery besides lower variation of strength compared to the corresponding all-cotton yarns. As a result, medium and long staple cottons can be upgraded to spin 15-40 counts finer by adopting the core-spinning technique. Fabrics woven from such yarns, by virtue of their cotton surface, can be dyed without the use of special techniques and are comparable in respect of the major fabric characteristics to those made from imported long staple cottons. Some of the precautions necessary for spinning and weaving of core-spun yarns are described in detail.</span>
