A confident understanding of fabric behavior and characteristics are vital in the design and development of a functional garment. In textile production technology one of the objectives of the manufacturer is to produce high quality fabrics or garment which will satisfy the customers’ need both in serviceability and in price. This research focus on the effect of warp count on cotton woven fabric mechanical properties tested with three count of fabric such as 17 Ne, 22 Ne and 24 Ne to be determine their mechanical properties like tensile strength, tear strength, pilling resistance and crease resistance performance. It evident from the result obtained that the fabrics posses which result from the type of warp count used. When the result indicated the tensile strength, tear strength and crease resistance value increase for used coarser count cotton yarn, on the other hand pilling resistance value increasing for finer cotton warp count used. Beside mechanical properties test result indicated that strength properties increased with increasing the coarseness of warp count because high fiber in the cross section of the yarn to enhance the strength value and crease resistant properties. When the pilling resistance increased with finer yarn used which attributed to the fact that finer yarns have low hairiness and high twisted yarn value than coarser yarn due to that fabric pilling rate decreased when the result. Finally Fabric testing plays a crucial role in gauging product quality, assuring regulatory compliance and assessing the performance of textile materials. It provides information about the physical or mechanical properties and the performance properties of the fabrics
