  • Study of Antibacterial Activity of Chitosan on Lyocell and Recycled Polyester Yarns
    ISSN: 2319-8753 International Journal of Innovative Research in Science, Engineering and Technology (An ISO 3297: 2007 Certified Organization) Vol. 3, Issue 2, February 2014 Study of Antibacterial Activity of Chitosan on Lyocell and Recycled Polyester Yarns Saranya Rajamanickam 1, Krishnaveni Vasudevan 2 P.G. Student, Department of Fashion Technology, Kumaraguru College of Technology, Coimbatore, Tamilnadu, India1 Associate Professor, Department of Fashion Technology, Kumaraguru College of Technology, Coimbatore, Tamilnadu, India 2 Abstract: Medical textiles are one of the essential materials for the production of medical garments and have been developed in the past decades. A medical textile is a type of advanced technical textile materials and is classified according to its performance and functional properties as being suitable for medical or hygienic products. Among the vast categories of medical textile products, the hospital textiles are most important and also expected to fulfill the hygienic, comfort and microbial resistance property requirements. The functional requirements of hospital textiles have led to the innovative use of a variety of natural and manmade fibers with enhanced comfort and hygienic properties in the development of new products for medical textiles. The lyocell and polyester fabrics play an important role in the hospital textiles. The new innovation of antimicrobial finishes on the fabric can minimize the transfer of micro- organisms on the wearer by creating as a physical barrier. Chitosan is a natural biopolymer and it has unique properties such as biodegradability, non-toxicity and antimicrobial activity. This work is an attempt to develop hospital textiles using lyocell and Recycled polyester fibers. The fibers were converted in to different composition of yarns such as 100% Lyocell, 100% Recycled polyester, 50:50 and 70:30 Lyocell/ Recycled polyester blended yarns using short staple spinning system.

  • Innovative Approach to High-Speed Spinning Using a Magnetically-Elevated Spinning Ring
    AUTEX Research Journal, Vol. 6, No 3, September 2006 © AUTEX INNOVATIVE APPROACH TO HIGH-SPEED SPINNING USING A MAGNETICALLY-ELEVATED SPINNING RING Faissal Abdel-hady, Yehia El Mogahzy, Sherif AbuElenin*, and Rabab Abdel-Kader Textile Engineering Department, Auburn University, Auburn, AL 36849, U.S.A. Abstract We introduce a new concept of ring-spinning. The model system built on the basis of this concept is capable of producing yarns at a production rate of up to 4 times that of the traditional ring-spinning system. This is a direct result of a ring rotational speed of up to 40,000 rpm. This new concept is termed ‘magnetic spinning’, and it principally consists of a lightweight rotor suspended magnetically inside a fixed stator; the rotor can spin freely inside the stator. The stator is equipped with four magnetic actuators that always keep the rotor in its central position. The rotor in this configuration replaces the ring and traveller in the traditional spinning system. The system’s concept and control analysis are discussed in this paper. Key words: ring-spinning, magnetic spinning, floating traveller, high-speed spinning, magnetic suspension Introduction In today’s technology, many spinning systems are used commercially to produce spun yarns with a wide range of values of characteristics. Among these systems, ring spinning enjoys the greatest diversity and the highest quality levels. Other spinning systems such as rotor spinning, air-jet spinning, and friction spinning suffer inherent limitations that make them suitable for only narrow ranges of yarn count and twist levels [3, 10, 12]. However, the major limiting factor in ring spinning is their low production rate in comparison with all new spinning technologies.
