Stiffness of Fabrics Made by Open End Yarns

Open end yarns are structurally different in character from ring spun yarns. This difference in structure could affect the yarn properties and consequently the fabric properties. This paper attempts a comparison of the stiffness properties of open end yarn fabrics and similar ring spun yarn fabrics using the SITRA Electronic Stiffness Tester. The important conclusions are that although open end fabrics show a higher stiffness than similar ring spun fabrics, there are directions in which the stiffness of open end fabrics is lower. Also comparison has been made of the stiffness behaviour of a open end fabric pile with that of the ring spun fabric pile.
