Reflecting Noble Luxury and Refinement, New Lightweight Wool Materials Are of Key Interest to Designers, Retailers and Bespoke Tailors
Reflecting noble luxury and refinement, new lightweight wool materials are of key interest to designers, retailers and bespoke tailors. Beyond demanding perfected fits and wool’s signature aesthetic, discerning consumers expect emotional, sensorial tactility in garments. Responding to luxury market demands, leading Italian and English spinners and weavers are introducing exclusive fine-micron yarns and fabrics, derived from rare Australian merino.

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).

An Overview of Spinning Technologies: Possibilities, Applications and Limitations
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.

Cotton and the Community: Exploring Changing Concepts of Identity and Community on Lancashire’S Cotton Frontier C.1890-1950
Cotton and the Community: Exploring Changing Concepts of Identity and Community on Lancashire’s Cotton Frontier c.1890-1950 By Jack Southern A thesis submitted in partial fulfillment for the requirements for the degree of a PhD, at the University of Central Lancashire April 2016 1 i University of Central Lancashire STUDENT DECLARATION FORM I declare that whilst being registered as a candidate of the research degree, I have not been a registered candidate or enrolled student for another aware of the University or other academic or professional institution. I declare that no material contained in this thesis has been used for any other submission for an academic award and is solely my own work. Signature of Candidate ________________________________________________ Type of Award: Doctor of Philosophy School: Education and Social Sciences ii ABSTRACT This thesis explores the evolution of identity and community within north east Lancashire during a period when the area gained regional and national prominence through its involvement in the cotton industry. It examines how the overarching shared culture of the area could evolve under altering economic conditions, and how expressions of identity fluctuated through the cotton industry’s peak and decline. In effect, it explores how local populations could shape and be shaped by the cotton industry. By focusing on a compact area with diverse settlements, this thesis contributes to the wider understanding of what it was to live in an area dominated by a single industry. The complex legacy that the cotton industry’s decline has had is explored through a range of settlement types, from large town to small village. -
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 Yarn with a Drop Spindle
Spinning Yarn With a Drop Spindle Using a spindle is a very economical way to learn handspinning for a beginner. They are inexpensive to buy, and also very easy to make. Once you have mastered the spindle you will have learned the steps needed for spinning on the spinning wheel: drafting out fibers, twisting the fiber into yarn, and winding up and storing the spun yarn. Tying on the Leader To begin spinning on a bottom whorl drop spindle, attach a leader to your spindle by tying a piece of yarn about 18 inches long onto the shaft right above the whorl, then take the yarn over the side of the whorl, loop it around the shaft underneath, and back over the side of the whorl, and secure the end onto the hook. Spinning Leave the fibers at the end of the leader loose. Let the spindle hang beneath your hand suspended by the leader. Take the spindle in your right hand and the leader in your left hand, spin the drop spindle from the shaft in a clockwise direction. This is the direction you will be spinning to make the yarn. Allow yourself time to practice making the spindle rotate. Repeat this process of spinning the spindle in the same direction until the leader begins to take in the twist. Leave a fluff of fiber at the end for joining on more fiber. Winding On Always keep tension on your newly spun yarn to allow the twist to run into the newly drafted fiber, if you release the tension, the twist will not travel up.
