An Approach to Super High-Speed Ring Spinning Frame
An Approach to Super High-speed Ring Spinning Frame By Keishi Fujisawa, Member, TMSJ Nihon Spindle Mfg. Ca., Ltd., Amagasaki, Hyogo Prefecture Basedon the Journalof the TextileMachinery Society of Japan,Proceedings, Vol. 23, No. 11, P773-781(1970) Abstract This articlesummarizes our studymade to obtaina superhigh-speed of 20,000rpm in spindle revolutionsof a ring frame,by improvingthe mechanismsof rotation parts such as spindle and ring, and by developingan advancedspeed controllerand speed regulator. Our study for speedingup the spindlerevolutions up to 20,000rpm is as follows: 1) We havesucceeded in developinga newspindle for ringframe, whichcan attain a speed of 20,000rpm, puttingthe spindlevibration underrestrain of the same level as in the con- ventionaloperation at 15 000 rpm. 2) All the bottlenecksof the ringsand travellersusually encountered during the high-speed operation of spindle have been broken by imporvingtheir mechanisms. 3) We have developeda speedregulators provided with wider rangesof speedand also a speedcontroller with lemientpitches to causeno suddenchanges in speed.

Introduction Since several thousand years ago, humans have been manufacturing linen, wool, cotton, and silk to be used as fibrous materials for clothing. In 繊維 (sen’i ), which is the word for “fiber,” the Chinese character 繊 (sen ) is a unit for decimal fractions of one ten-millionth (equal to approximately 30 Ǻ), while 維 (i) means “long and thin.” Usually, fibers are several dozen µ thick, and can range from around one centimeter long to nigh infinite length. All natural materials, with the exception of raw silk, are between several to several dozen centimeters long and are categorized as staple fibers. Most synthetic fibers are spun into filaments. Figure 1 shows how a variety of textile product forms are interrelated. Short fibers are spun into cotton (spun) yarns, whereas filaments are used just as they are, or as textured yarns by being twisted or stretched. Fabric cloths that are processed into two-dimensional forms using cotton (spun) yarns and filament yarns include woven fabrics, knit fabrics, nets, and laces. Non-woven fabrics are another type of two-dimensional form, in which staple fibers and filaments are directly processed into cloths without being twisted into yarns. Yet another two-dimensional form is that of films, which are not fiber products and are made from synthetic materials. Three-dimensional fabrics and braids are categorized as three-dimensional forms. This paper discusses spinning, or the process of making staple fibers into yarns, and winding, which prepares fibers for weaving.

Industrial Lyme - Paper 2: The Woollen Cloth Industry in the Lim Valley © Richard Bull & Lyme Regis Museum Revised with extra images July 2015 Like all research, this is on-going. If you know more, or are descended from any of the families involved, please get in touch with the author via Lyme Regis Museum. Summary Woollen cloth has been made in the Lim Valley from at least medieval times, but this paper is more about the factories in Lyme Regis and Uplyme that made high-quality West of England coat cloths. The factories in Lyme were bankrupt in 1847, leaving the Uplyme factory to soldier on against Yorkshire competition until it was destroyed by fire in 1866, whilst being modernised. In Lyme the factories were started up again in the 1850s to make silk thread and hemp twine, but only for a short period; these are the subjects of other papers in this series. This paper contains: the background to the trade, the history of the factories and a walking trail to see the mills. Cloth making – the essential process in a nutshell Sheep fleeces are packed on the farm into big canvas bags called woolsacks. At the factory the fleeces are scoured (washed) to remove lanolin (wool- grease), dirt and adhering vegetable material. Then the fleeces are scribbled (torn up into pieces), combed and carded to produce rovings, long strips of wool ready for spinning. Washed and combed fleece being fed into a carding machine at Coldharbour Mill, Uffculme, Devon Industrial Lyme Paper 2 – The Woollen Cloth Industry © R Bull & Lyme Regis Museum 1 Spinning means to draw out and twist - and by this process the scales of the individual wool fibres lock together to produce a thread known as a single. -

Current and Future Trends in Yarn Production1
Volume 2, Issue 2, Spring 2002 CURRENT AND FUTURE TRENDS IN YARN PRODUCTION1 William Oxenham, Ph.D. College of Textiles, North Carolina State University ABSTRACT While developments in yarn manufacturing continue to be promoted by machinery makers, spinners are challenged to produce the best quality yarn at an acceptable price. This often results in a compromise, since improved yarn quality can usually only be achieved at a higher processing cost (including raw material selection). An additional difficulty is that the significance of the various attributes of quality change for different yarn’s end uses. While the solution to lowering yarn costs, that has been adopted in recent years has been to create large, almost fully automated spinning mills, this philosophy is presently being questioned, since this significantly reduces flexibility with respect to the fiber and yarn type that can be processed. This is obviously at odds with the current paradigm of customer driven, quick response manufacturing, since this demands inherent flexibility in the successful supplier. This paper reviews the current state of technological innovation in yarn production and examines the relative merits and disadvantages of each system. Some insight will also be given concerning those factors that limit further development of some of these systems. Historical trends in US yarn production have also been surveyed, and the combined information obtained is used as an indicator of the future directions in this key industry. KEYWORDS: Yarn Production, Spinning, Vortex Spinning, Centrifugal Spinning 1. INTRODUCTION shortcomings in certain aspects of yarn and fabric quality (Figure 2). This aspect Research into new technology for yarn cannot be over stressed since while ring formation peaked in the 60’s & 70’s. -

Inventions in the Cotton Industry
Inventions in the Cotton Industry Paisley Thread Mill Museum A Family of Threads John Kay: The Flying Shuttle 1733 • For centuries handloom weaving had been carried out by the shuttle with the yarn on being passed slowly and awkwardly from one hand to the other. • In 1733 John Kay patented his flying shuttle which dramatically increased the speed of this process. • Kay placed shuttle boxes at each side of the loom connected by a long board, known as a shuttle race. • With cords, a single weaver, using one hand, could knock the shuttle back and forth across the loom from one shuttle box to the other. • A weaver using Kay's flying shuttle could produce much wider cloth at much faster speeds than before. James Hargreaves: The Spinning Jenny 1764 • In 1764 Hargreaves built what became known as the Spinning- Jenny. • The machine used eight spindles onto which the thread was spun. • By turning a single wheel, the operator could now spin eight threads at once. • Later, improvements were made that enabled the number to be increased to eighty. • However, the thread that the machine produced was coarse and lacked strength. Richard Arkwright: The Water Frame 1771 • Richard Arkwright: The Water Frame 1771 • In 1762 Richard Arkwright met John Kay and Thomas Highs, who were trying to produce a new spinning- machine, to improve on the Spinning-Jenny. • Kay and Highs had run out of money and Arkwright offered to employ John Kay to make the new machine, with other, local craftsman to help. • It was not long before the team produced the Spinning-Frame.
