TAG : Lea Method
Compare the tensile strength of dry and wet cotton yarns by lea method and calculate their CLSP.
The strength along the length of a body is known as its tensile strength also called linear strength of that body. In the textile fibers or yarns only tensile strength is calculated due to high length to width ratio of the textile materials. The tensile strength values of the dry and wet cotton yarns varies very much from each other. The strength of wet cotton yarns is greater than that of dry cotton yarns. This is due to the formation of hydrogen bonds between the water molecules and the hydroxyl groups in the cellulosic rings of the cotton fibers in the wet state. There is one phenomenon known to stand that when the cotton gets wet its crystalline region increases hence the strength of the fibrous structure increases.
