end uses of rotor spun yarn

Young Ryul Kim. Rotor Spun yarns found with frequent breakage during knitting [6] and more irregular than ring yarn [34]. In order to improve yam properties and produce novel yams, we investigate the effects of combinations with typical hybrid yams by inserting two filament yarns with varying filament over-feeds. c) Air-jet yarn. Yarn formation in friction spinning system. In this process the fiber sliver is separated into single fibers and in which the separated fiber material is brought by an air stream to a collecting surface from which it is drawn off while being twisted. Each system has its advantages and limitations in terms of technical feasibility and economic viability. A method of piecing together a continuous filament yarn and a rotor spun staple yarn with the broken end of a two-ply combination yarn formed by ply-twisting a continuous filament yarn with a yarn of staple fiber on an open-end spinning machine which includes . A Barella, A M Manich, P N Marino and J Ganofalo: Factorial Studies in Rotor Spinning, Part I, Cotton Yarns, J Textile Institute, 1983, 74, 6, pp 329. Ring spinning is a comparatively expensive process because of its slower production speeds and the additional processes (roving and winding) required for producing ring spun yarns. The yarn characteristics of rotor spun yarn are affected by various factors related to raw material, machine parameters and processing parameters. You Huh. open-end or rotor spinning. in Textile Engineering(DIU) BSc. 0 Rotor spun yarns are more even, somewhat weaker and has a harsher feel than ring spun yarns. The MVS knit fabrics exhibited better surface appearance after repeated launderings. Anindya Ghosh, ‘Studies on structural aspects of ring, rotor Air-jet and open-end friction spun yarns’ National conference on Emerging trends in textile, fiber & apparel engineering, Govt. Ringspun yarns produce high quality and are mainly produced in the fine (60 Ne, 10 tex) to medium count (30 Ne, 20 tex) range, with a small amount produced in the coarse count (10 Ne, 60 tex) range. You Huh. The knit fabrics made from MVS yarns had better overall surface definition, especially compared to ring yarns. college of engineering, Berhampore, West Bengal, March 200 6. On the Basis of spinning machine used a) Ring yarn. The process which was termed 'ROTONA" made its first international appearance at ATME '82. Ring, Rotor and Air-jet spinning systems provide yarn with different structures and properties. Advances in Yarn Spinning Technology Book suitable one according to end use and others economic aspects. places, and neps) are generally lower than ring and rotor yarns, especially for finer yarn counts. We have developed a mechanical hybrid yarn spinning system that produces different yam types on a modified open-end rotor spinning frame. There was slightly less torque or skew with the MVS fabrics compared to ring-spun fabrics. The properties of ring-spun and rotor-spun yarns and of the fabrics woven from these yarns have been compared. End uses … Air jet spun yarns are mainly produced in the medium count (30 Ne, 20 tex) range and are mainly polyester/cotton blended yarns. rotor-spun yarn tend to distribute in outer layers, than in ring-spun yarns. The system spins yarn directly from slivers, using a spinning rotor and a withdrawal system that imparts false twist to form the fibers into a yarn. Both technologies have their own fields of end-uses, and ring spinning has been boosted further with the development of compact spinning, resulting in much less yarn hairiness thanks to its reduced, or compact, spinning triangle. E Koc, C A Lawrence and C Iype: Wrapper Fibres in Open-end Rotor Spun Yarn - Yarn Properties and Wrapper Fibres, Fibres and Textiles in Eastern Europe, 2005, 13, No 2, pp 50. Open end, Rotor or Break Spinning used for high quality threads; Dref friction spinning for other yarns. and open-end rotor spun yarns; they determined various mathematical models on tenacity, elongation at break, unevenness, hairiness and the number of faults on the yarn’s linear density. b) Rotor yarn. Open-end spinning requires fewer steps than ring spinning, because roving is not needed, and a full-sized package is made directly on the machine. Faculty of Mechanical and Industrial System Engineering, Kyung Hee University, Yongin, Kyunggi-Do, 449-701, South Korea See all articles by this author. So it is very important for spinners to find out a suitable one according to end use and others economic aspects. Rotor spun yarns are mainly produced in the medium count (30 Ne, 20 Tex) to coarse count (10 Ne, 60 Tex) range. End uses include woven sheeting and knitted lightweight shirting. Presented by: Rajeev Kumar (21) Sanath kr. It can be concluded that if the rabbit hair/cotton blended 62.5 tex yarns are spun, the rotor-spun yarns will show more of an appearance of rabbit hairs than the ring-spun yarns. Koҫ, Erdem.et al.,Wrapper Fibres in Open-End Rotor-Spun Yarns: Yarn Properties and Wrapper Fibres,FIBRES & TEXTILES in Eastern Europa,2005. b) S twisted yarn. Open-end (OE) rotor spun yarns have certain characteristics which differentiate them from conventional ring-spun yarns. Rotor spinning, also known as open-end spinning, was developed in the 1970s and early 1980s. 10. Wrap spun rotor yarns • A method of producing Wrap-Spun Rotor yams bas been developed in Czeckoslovakia. Each system has its advantages and limitations in terms of technical feasibility and economic viability. Yarn samples were converted into knitted fabrics in a single jersey circular knitting machine and dyed with reactive dyestuff to determine the physical performances of the yarns in knitted form. This paper provides preliminary results on the relative performance of the adaptive neuro-fuzzy system inference (ANFIS) model versus linear multiple regression method, when applied to the use of cotton fiber properties to predict spun yarn strength obtained from open-end rotor spinning. Ring, Rotor and Air-jet spinning systems provide yarn with different structures and properties. The design of the combined experiment was sensitive to interactions of these factors. 11. Rameshkumar C., et. Basic requirements of Air-Jet Spinning Machines . Advantages of Rotor Spinning 0 The production rates of rotor spinning is 5-7 times higher than that of ring spinning and as the machines are fed directly by sliver and yarn is wound onto packages ready for use in fabric formation the yarn is a lot cheaper to produce. As the rotor spun yarn has bipartite structure the core exhibits twist structure more or less similar to that in ring spun yarns and the sheath is characterised by belts having varying intensity and direction of wrapping. Rotor-spun yarns are inherently weaker 5than ring-spun yarns because of structural difference and the manufacturers are concerned about the weavability and fabric strength. We assessed processing behavior by the end-break rate, using a BD200S rotor spinner, and yam quality by tests of evenness, single-end tenacity, and appearance. Moreover, there are a lot of open end yarn used in pile fabrics, apparel, household, industrial and … It is also known as break spinning or rotor spinning . The element that inserts the twists can be a rotor or other mechanical device, a friction device, or an air jet. Rotor spun yarns are more even, somewhat weaker and have a harsher feel than ring spun yarns. On the direction of twist a) Z twisted yarn. in Textile Engineering(CU) 2.

END USES FOR OPEN END SPUN YARNS Open end yarns produce a different characteristic in the end product. 11. in Textile Engineering(CU)BSc. Ring, Rotor and Air-jet spinning systems provide yarn with different structures and properties. in Textile Engineering(DIU)MSc. The use of this system has two basic advantages. Friction spinning is the fastest of all these techniques though the yarn is irregular and bulkier, making it suitable only for some applications. Analyzing Structural and Physical Properties of Ring, Rotor, and Friction Spun Yarns Show all authors. 100% desirability satisfaction can be achieved for specific yarn quality parameters by process optimization, following USTER ® benchmarks, at a rotor speed of 77,800 rpm and 700 twists per meter [35]. This system is much less labour-intensive and faster than ring spinning with rotor speeds up to 140,000 rpm. The results revealed that vortex spun yarns have lower hairiness and better pilling resistance over ring and open-end rotor spun yarns. Types of yarns on the basis of Structure Another classification of yarn can be obtained on the basis of structure and this classification is easier way to understand and define many types of textile yarns. The end use of rotor-spun yarns will show better rabbit hair performance than ring-spun yarns. So, these yarn may be used in fabrics where the importance of uniformity and smoother surface. 4. Each system has its advantages and limitations in terms of technical feasibility and economic viability. 1. The Rotor design is the key to the operation of the open-ended spinners. Open-end spinning or open end spinning is a technology for creating yarn without using a spindle. Sliver from the card goes into the rotor, is spun into yarn and comes out, wrapped up on a bobbin, all ready to go to the next step. As is the case with rotor spun yarns, air jet yarns are more even, but weaker and have a harsher feel than ring spun yarns. Open-end spinning is defined as "A system of spinning spun yarns from sliver by introducing twist into the yarn without package rotation by simply rotating the yarn end at a gap or break in the flow of the fibers between the delivery system and the yarn package. If open-end spun yarns are to find wide use, it is necessary to understand more fully the structure of the yarns. End uses include denim, towels, blankets socks, t-shirts, shirts and pants. So it is very important for spinners to find out a suitable one according to end use and others economic aspects. This article presents a comparative analysis of the properties of cotton yarn spun on aerodynamic compact spinning and open-end rotor spinning systems. Search Google Scholar for this author, Young Ryul Kim. There is no roving stage or re-packaging on an auto-coner. The fibre in the core are twisted helically with the fibres near the yarn axis showing low helix angle while those near the surface have greater helix angles.
