Since yarn from the ring cop is normally over-end withdrawn during the winding process, the spindle speed is taken for calculating the turns/cm in the yarn instead of using traveller speed. STRUCTURE AND WORKING PRINCIPLE OF AIR-JET/ VORTEX SPINNING SYSTEM: Twist insertion method in air-jet/vortex spinning: You may also be interested in following articles: Yarn count determination from fabric swatch or count determination from short length of yarn, Advantages and disadvantages of open end yarn, Advantages and disadvantages of ring frame process. This system is much less labour-intensive and faster than ring spinning with rotor speeds up to 140,000 rpm. The first open-end machines in the United Kingdom were placed, under great secrecy, by Courtaulds into Maple Mill, Oldham in 1967. The twist multiplier is used to calculate the amount of TPI to be given to the cotton yarn during spinning. Additional: Math Calculate production. If you could open the door and pull out a sheet, it would spin together as you pulled it out. Many manufacturers compete to provide the spinning machines that are essential to meeting the demand by delivering increases in spinning productivity and additional improvements in yarn quality. In the vortex spinning system, the twist insertion system  is composed of an air-jet nozzle and a hollow spindle with a yarn passage through it. Berthelsen developed a relatively perfect open end. Assume all. So if the unit is not mentioned, it is understood to be a production… There is no roving stage or re-packaging on an auto-coner. 25+ years experience in textile industry. This is due to the parallel withdrawal of roving during spinning. Author: Textiles Committee Created Date: 9/1/2015 9:58:37 AM The online consultancy available. Inventory control means the accurate calculation . (L x Ktex x 60 x effy) / ( 1000 ) The higher production rate results in the form of yarn cost reduction. The energy requirement per one kilogram of ring-spun yarn varies between 3.49 and 3.62 kWh/kg, whereas in the case of open-end spinning, energy requirements vary between 2.44 and 2.58 kWh/kg of yarn. effy- efficiency. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. combers”. 4. 39 It should also be noted that energy consumption to produce a unit of yarn will vary significantly between various … Thus, the overall draft of an open-end frame is likely to be quite high; as a result, open-end Each type of fibre may require a different rotor design for optimal product quality and processing speed. Over the past three centuries spinning technology has been continuously improved through thousands of minor innovations, and occasional major advances that have collectively increased the quality and lowered the cost of producing yarn dramatically. Higher productivity almost 7 times in the case of 10s and high efficiency. Studying the yarn formation with the swirling air concept arouse of interest of the researchers for a long time because it appears to be easy to understand as a spinning principle. The energy requirement per one kilogram of ring-spun yarn varies between 3.49 and 3.62 kWh/kg, whereas in the case of open-end spinning, energy requirements vary between 2.44 and 2.58 kWh/kg of yarn. Under certain circumstances, elimination of the second passage draw frame. spinning; this characterizes the yarn property produced by open-end spinning. The presence of short fibers in the material fed does not seriously affect the efficiency of Open end spinning and it may be that process will have a bright future in the spinning of waste. The Rotor design is the key to the operation of the open-ended spinners. Improved BD200 with G5/1 Rieter were presented with first mill of OE coming under production. These kinds of systems are known as the vortex yarn spinning systems. Less labor and power cost per kilogram of. A method is provided for operating a textile machine having a plurality of work stations wherein, during normal operation of the work stations, a yarn is produced or is rewound from a delivery coil onto a receiver coil. Production The output of a m/c per unit time is called its production. Textile manufacture during the Industrial Revolution, Amalgamated Association of Beamers, Twisters and Drawers (Hand and Machine), Amalgamated Association of Operative Cotton Spinners, Amalgamated Textile Warehousemen's Association, General Union of Lancashire and Yorkshire Warp Dressers' Association, Lancashire Amalgamated Tape Sizers' Friendly Society, North East Lancashire Amalgamated Weavers' Association, Northern Counties Textile Trades Federation, United Textile Factory Workers' Association, https://en.wikipedia.org/w/index.php?title=Open-end_spinning&oldid=937127354, Creative Commons Attribution-ShareAlike License. The fibres that rotate around the hollow spindle tip attach to the core fibres by wrapping onto them and yarn with a similarly real-twisted structure is formed. In this report, discussion will be made on drafting and twisting processes in the open-end spinning machine MS-400 and their relation to the yarn properties. • The twisting motion tends to propagate from the spindle toward the front rollers. Our enterprise successfully attained IS9001 Certification and European CE Certification of Open End Spinning Production Calculation, open end spinning production calculation, rotor spinning production calculation, You can always find the merchandise you need in our company! Also witnessed first automated machine from Suessen equipped with Spincat and Cleancat which opened up the industrial rotor spinning breakthrough. 7-13. of machine=12, heads per frame=360, rotor speed=100000 rpm, count=12, Tm= 4.5, efficiency=95% 45. *evelopment stages of Open-end Spinning ï ¢ Berthelsen developed a relatively perfect open end. Welcome to inquire us about our product and anything we know and we can help in auto spare parts. Also the characteristics of the open-end spun yarn will be considered. There was a considerable increase in machine manufacturer and newer and improved. Witnessed Schlafhorst with Autocoro machines, which made a mark in open-end market. Production in kgs / hr. Open-end spinning is a technology for creating yarn without using a spindle. Kaplan E., Koç E.; Investigation of Energy Consumption in Yarn Production with Special Reference to Open-End Rotor Spinning. 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. AIRJET/ VORTEX SPINNING METHOD (A OPEN END SPINNING PROCESS) AIR-JET SPINNING SYSTEM: • The production is 2-3 times more than rotor spinning yarn and 10-20 times more than ring frame. The formed yarn is then delivered out of the nozzle through the yarn passage of the hollow spindle with the drag of the delivery rollers and fed to the winding unit. 2.2045- to convert from lbs to kilograms. Yarn Tension in Ring Spinning; Spinning Balloons; Compact spinning; Forces acting on the traveller; Ring Spun Yarns. Open end spinning is an excellent short-term blending process. One disadvantage of open-end spinning is that it is limited to coarser counts, another is the structure of the yarn itself with fibres less in parallel compared to ring-spun yarns, for example, consequently cloth made from open-end yarn has a "fuzzier" feel and poorer wear resistance.
