Recently, it is tried to gain products which have new properties by doing changes in different stages of textile production in order to create difference. One of these changes is the adding studies of second, third and even sometimes fourth material into the structure of yam. These studies can differ depending on the type and structure of yam and fabric manufacturing system. For example, in yam manufacturing it can be spinning affected, twist affected, winding affected, etc. These studies which are made in order to create difference in textile yams and fabrics are also providing difference in the structure and properties of the new product. For this reason, in this new situation, structure and properties of this kind of products must be known. In this study, it is tried to examine the changes in properties (abrasion, strength, extension and elongation) of classical fabric structure by adding yams containing elastane into the fabric.
