Abstract
Yarn prepared from two technologies i.e. Ring frame and compact spinning system analyzed on Uster Tensorapid, Uster Evenness Tester. It was observed that yarn prepared with compact spinning system gives less variation in end products. Study also reveals that there was significant difference between tensile properties of yarn which was produced from compact spinning and ring spinning. Yarn produced from two technologies pretreated with scouring and bleaching process and structural changes occurred in yarn were analyzed on Uster Tensorapid, Uster Evenness Tester. In the present investigation it was observed that yarn produces from both spinning technique shows, strength reduced and elongation improved in compact spun yarn and count C.V. also found reduced for both systems after scouring and bleaching process. It was noticed that, yarn produced from compact spinning gives less yarn hairiness because of reduction in spinning triangle and protruding fibers were goes into yarn body which gives very good impact on subsequent processes.
Highlights
Compact spinning process has become firmly established in the market in recent years
Chemical and Mechanical finishing process change properties of fiber assemblies according to its intensity cotton fiber contain approximately 90% cellulose and various non-cellulose substances such as waxes, fats, pectin, proteins and coloring matter

Summary
Compact spinning process has become firmly established in the market in recent years. An adequate preparation is necessary either to remove or to decolorize the impurities present in cotton so that they will not interfere in the subsequent process the purpose of bleaching includes the removal of the various natural, added and acquired impurities from the grey cloth and efficiently as possible, with minimum or no damage of the fiber, and leaving the yarn in a perfectly white state. Preparation A: is added in stock tank contain Hot water [70°C] mixed well and transferred to the main KIER where the Grey cheese. Preparation C: is readily available in stock tank containing warm water (50°C) and drain the bath. The Preparation “C” is transferred to the main KIER and run for 15 minute and drains the bath. The effect of bleaching process on properties ring and compact yarn [3].
