  • 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.

    Indian Journal of Fibre & Textile Research Vol. 17 , December 1992, pp. 255-262 An overview of spinning technologies: Possibilities, applications and limitations K R Salhotra Department of Textile Technology. Indian Institute of Technology. Hauz Khas. New Delhi 110016. India Received 12 August 1992 The new spinning technologies such as rotor, air jet and friction spinning have tremendous potential for hi gher productivity. However. at present these technologies not o nl y suffer from the problem of imparting some undesirable properties to the fabric but a lso have limited applicability due to the restricted choice of fibres and counts which can be successfully spun on them. Ring-spinning system, though having lower productivity, does not have these drawbacks. This system, therefore, with the incorporation of some recent improvements is likely to occupy the centre stage for the next few years.

  • The Textile Machinery Collection at the American Textile History Museum a Historic Mechanical Engineering Heritage Collection
    THE TEXTILE MACHINERY COLLECTION AT THE AMERICAN TEXTILE HISTORY MUSEUM A HISTORIC MECHANICAL ENGINEERING HERITAGE COLLECTION Textiles are an important part of our everyday lives. They clothe and comfort us, protect our first-responders, Introduction filter the air in our automobiles, and form the core of the fuselage in our newest aircraft. We enjoy their bright colors, wrap up in their warmth, and seldom give a second thought to how they make bicycles stronger and lighter or how they might be used to repair our vital organs. As textiles have changed from the first simple twisted fibers to high-tech smart fabrics, the tools and machinery used to make them have evolved as well. Drop spindles and spinning wheels have given way to long lines of spinning frames. And looms now use puffs of air instead of the human hand to insert the weft thread in a growing length of fabric. During the eighteenth and nineteenth centuries, textile manufacture was the catalyst for the Industrial Revolution in America. It was the leading edge in the transformation from an agricultural to a manufacturing economy and started the move of significant numbers of people from rural areas to urban centers. With industrialization came a change in the way people worked. No longer controlled by natural rhythms, the workday demanded a life governed by the factory bell. On the consumer side, industrialization transformed textiles from one of a person’s most valuable possessions to a product widely available at incredibly low prices. For more than a century, textile mills in Great Britain and the United States dominated textile production and led the industrial revolution in both Europe and North America.

  • Spinning Jenny
    Spinning Jenny There were other inventors before and around the time of Richard Arkwright. The first was probably James Hargreaves from Lancashire. He invented the “Spinning Jenny” in 1864-1865 with eight and later even more spindles, which was enough to spin enough yarn to match the modern fly- shuttle. The yarn which could be produced with the Spinning Jenny, however, was not very strong. This only changed when Richard Spinning Jenny Arkwright invented the water-powered spinning frame or water frame. This was also the moment when the water from streams and rivers became essential to drive the new machines. The true origin of these inventions and the identity of the inventors is not quite clear. Especially a Mr Thomas Highs claimed that he built the Spinning Jenny and that Richard Arkwright just copied some of his ideas. Others say that John Kay, a mechanic who had worked for both, Highs and Arkwright, was the the improved Spinning Jenny rightful creator of the machines. Richard Arkwright even lost the right on his exclusive patent, which would have given him a huge advantage over every- body else. Richard Arkwright became a very impor- tant and very rich entrepreneur. If you travel around Derbyshire today you can still witness his achievements and his wealth: many of the mills, factories, workshops and houses which he owned can still be seen today. It is said, however, that he was not a very nice man and it was difficult to get along with him. Spinning frame by R.

It is observed that the tenacity and work of rupture of core-spun acrylic yarns are higher than that of 100 % acrylic yarn, whereas the breaking elongation of all the yarns is more or less same. Nylon core yarn apparently exhibits slippage between sheath fibres and core during the application of tensile load. Packing coefficient values indicate that the structures of core - spun acrylic yarns are less compact than that of acrylic yarn.

The starting point was centred around wool and later cotton became the major commodity that was influencing the economy. Through the inventions of people like Richard Arkwright and James Hargreaves, the textile industry received the technological advance that it needed and this in turn pushed Britain into the world’s major proponent in the textile industry. Further expansions continued until the mid 18th century, when the difficulty in obtaining raw cotton and competition from other countries began to mark the decline for the cotton industry in Britain.
