Studying the Effect of Different Kinds of Twill ( Gabardine) Fabrics on Some Mechanical Properties of Sewing Joints

Twill Fabric is considered as the second  textile  which is commonly used and it differs in its appearance from the plain fabric as a result of its construction method and the entrance of wrap and weft thread together and fabric composition Twill, it has many kinds all are characterized by parallel lines in the fabric with its appearance in the direction of the warp and the weft and it is  called the Twill lines so this research deals with the effect of four types of sewing on different kinds on the gabardine (natural- bland – synthetic) and study the effect mechanical properties like tightening force and extended and durability on the quality of the sewing joints, the research reached in its results that the best type of sewing is the simple sewing with the natural gabardine then the simple sewing with the synthetic  gabardine  (polyester100%) then the  decorated sewing with the natural gabardine (100% cotton) then the flatted sewing with the bland  gabardine (polyester 77% - cotton 23%).
