Compare the Tensile Strength of Ring Spun and Rotor Spun yarns having same Count.
In this experiment different properties of ring and rotor spun yarns were compared. The properties studied are breaking work, breaking force, tenacity and elongation of ring and rotor yarns. The yarns used for this experiment both have 20s count. The results showed that the ring spun yarns have good properties then the rotor spun yarns.
To Compare the tensile strength of 100 % pure cotton and its blends, also calculating their CLSP values.
This experiment is done to see how same count of different types of yarns has different strength and CLSP. We will also see the factors on which tensile strength of a product depends upon and when to use which yarns for different applications.
Determination of Tenacity and Percentage Elongation of Single Cotton Yarns
The tensile testing of single yarns is very important in the textile industry, as yarn coming from the spinning process has to pass through a large amount of loading, unloading, tension and tension-less mechanisms until the final product is made. Hence a yarn with good tensile strength or tenacity can bear all the forces during the textile manufacturing process and our final product will be of good quality.
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.
