Thesis Title: The comparison of a 100% cotton air jet spun yarn produced on the 881 Murata Twin Spinning Machine to a comparable ring spun yarn

Abstract: Much like the world around us, the textile industry is experiencing tremendous change and progress. with this comes new techniques and systems for manufacturing. Each year the textile industry is offered many new systems that are designed to give the industry a competitive advantage in the areas of production. It is neccesary to evaluate and compare these new systems to the well established systems. These comparisons are performed in order to characterize these new systems into the areas in which they will be most effective. This thesis research compared and . . evaluated a new air jet yarn for weaving to a well established weaving yarn. The Murata Twin Spinner is a newly developed and recently introduced air jet spinning machine. The Twin Spinner produces two individual yarns and winds them onto one single package. These packages are sent through a 2-for-1 twisting process that results in a plied air jet yarn. The Twin Spinner will also be used with a 100 percent cotton fiber. This is the first time 100 percent cotton has been used in air jet spinning. The Twin Spinner is also said to offer a cost effective replacement for a ring singles yarn with a higher quality plied yarn. Although much research has been conducted on the actual production of the Murata Twin spun yarn, .system has had little research conducted on the this new yarns performance in weaving. This research has defined the advantages for the yarn producer, however it is important to determine whether this new yarn system offers advantages to the woven fabric producer. The thesis research that has been performed is a comparison of a 40/2 Murata Twin Spun yarn to a 40/2 Ring spun and 20/1 ring spun yarns. The comparisons were made in the performance parameters of yarn, slashing, weaving and fabric. The results of the thesis research are as follows: 1. Yarn Performance: The Murata Twin Spun Yarn is comparable to both the plied and singles yarn but is not superior. 2. Slashing Performance: Size penetration and encapsulation is sufficient at low add-on levels. 3. 4. weaving Performance: The Murata Twin Spun yarns' structure enabled· it to weave in the unsized state and also performed superior to the ring singles yarn in the low add-on levels. Fabric Performance: The Fabric test results were similar to the yarn performance with the Murata Twin spun yarn being comparable but not superior. These results can be used to-characterize the Murata Twin Spun yarn. The size application quality, that is size encapsulation and penetration, reaches a sufficient level at low add-on levels. The Murata Twin Spun yarn offers many possibilities in the areas of unsized and low add-on weaving. The data in this thesis can be used to determine the specific areas in woven fabric production to which this air jet yarn technology can be applied.
