Abstract
Mercerizing is one of part of wet processing technology. It is the special type of treatment.Mercerization is done to get some special properties of the textile materials. In this process, the physical properties of the material get change. The mercerization process essentially consists of treatment of cotton yarn in high concentration caustic soda under tension. If cotton is dipped into a strong alkaline solution such as lithium hydroxide, caustic soda, or potassium hydroxide, the fibers will swell and shrink. If the fibers are placed under tension while in this swollen state and then rinsed with water, the alkali will be removed and a permanent silk-like luster will result It will be highly desirable to introduce this process in khadi sector which will lead to considerable saving in the dying cost. The handling of the hank is in appropriate; disarrangement of the lengths of yarn in one loop can result in different tensions, leading to uneven mercerization due to uneven tension is an unavoidable problem in this methods. This not only reduces productivity, but also results in many yarn-piecing defects during production. In this process tension can be derived by using proper shaft in mercerization machine by measuring the load required to keep the yarn or the fabric at the same length. The latter tension, being a tension intentionally exerted during mercerization, can be considered in three stages, 1) These being during the penetration of the alkaline solution and the swelling, during the fixing of the dimensions 2) Temperature during the treatment, 3) Control of the tension during the different stages is important in the supervision of the mercerizing process. In this process number of hanks are loaded on shaft and rotated for required time. Due to caustic soda treatment, the yarn get swell and length of yarn reduced upto 1/4th, due to continuous rotation of shaft, the load developed on shaft and shaft get bend. These problems may be overcome by designing of optimized shaft in mercerization machine.
