Using Cotton Sliver Draft Force to Evaluate Textile Processing Efficiency, Part I
USING COTTON SLIVER DRAFT FORCE TO EVALUATE TEXTILE PROCESSING EFFICIENCY, PART I D. D. McAlister, III, J. D. Bargeron, L. C. Godbey ABSTRACT. Fiber bundles in sliver form more closely represent the fiber bundles commonly used in commercial testing. Therefore, this experiment focused on studying drafting force using untwisted fiber bundles (sliver) rather than twisted fiber bundles (roving) as had been previously studied. Four cottons of similar micronaire but different lengths were utilized for this experiment. Ring spun yarns of three different linear densities were produced from each cotton to cover the range of coarse to fine yarns commonly produced in a textile mill. Fiber quality, processing quality, and yarn quality were measured for each cotton in addition to finisher sliver drafting force. The analysis of the data indicates that short fiber content has the greatest impact on drafting force. In addition, it appears to be possible to determine processing waste and spinning efficiency levels through the determination of drafting force of sliver. Keywords.

Spinning Alpaca: Fiber from Huacaya Alpaca to Suri Alpaca (And Beyond)
presents A Guide to Spinning Alpaca: Fiber from Huacaya Alpaca to Suri Alpaca (and beyond) ©F+W Media, Inc. ■ All rights reserved ■ F+W Media grants permission for any or all pages in this issue to be copied for personal use Spin.Off ■ spinningdaily.com ■ 1 oft, long, and available in a range of beautiful natural colors, alpaca can be a joy to spin. That is, if you know what makes it different from the sheep’s wool most spinners start with. It is Sa long fiber with no crimp, so it doesn’t stretch and bounce the way wool does. Sheep’s wool also contains a lot of lanolin (grease) and most spinners like to scour the wool to remove excess lanolin before they spin it. Alpaca doesn’t have the same grease content, so it can be spun raw (or unwashed) pretty easily, though it may contain a lot of dust or vegetable matter. Alpaca fiber also takes dye beautifully—you’ll find that the colors will be a little more muted than they would be on most sheep’s wool because the fiber is not lustrous. Because alpaca fiber doesn’t have crimp of wool, the yarn requires more twist to stay together as well as hold its shape over time. If you spin a softly spun, thick yarn, and then knit a heavy sweater, the garment is likely to grow over time as the fiber stretches. I hadn’t much experience spinning alpaca until I started volunteering at a school with a spinning program and two alpacas on the working farm that is part of the campus. -

START SPINNING: EVERYTHING YOU NEED TO KNOW TO MAKE GREAT YARN PDF, EPUB, EBOOK Maggie Casey | 120 pages | 01 Apr 2008 | Interweave Press Inc | 9781596680654 | English | Loveland, CO, United States Start Spinning: Everything You Need to Know to Make Great Yarn PDF Book To make two-ply yarn, take two singles strands or both ends of the same strand , attach them both to your spindle, and twist them around each other in the opposite direction from how you originally spun them. When you spin, you put twist into fibres so that they hold together to form a continuous thread. Navajo Plying - Making a three-ply yarn 8. Designed to appeal to the beginning spinner, tips and hints are provided that illustrate how easy, enjoyable, and relaxing spinning can be. When I was in Kenya, women spun Romney wool chiefly "in the grease," but it often locked in large amounts of dirt in the process. Spin spin spin! Covers fiber characteristics, preparation and spinning, choosing a wheel, and crafting the finished yarn into useful and attractive pieces. I Made It! Leave the original loop of fiber anchored on the spindle hook. Description If you are a knitter or crocheter looking to take the step from just using manufactured yarn to making your own this is a great book to get you started. A bunch of loose fibers will fall apart if you pull on their ends. Launching a Patreon! First and foremost, you want a balanced drop spindle that spins true. Either one will do just fine to learn on. It is also much easier to learn to spin wool than silk, or cotton and other vegetable fibres. -

Hand Spinning and Dying Mohair D L Stapleton
Hand Spinning and Dying Mohair D L Stapleton. 28 Bowman Ave. Orange NSW 2800. Using mohair in hand craft is quite different to farming and the production of fibre for the textile industries. Nevertheless, fibre crafting with mohair gives insights and understand of the concepts of fibre quality. Hand spinning is the most obvious craft activity, but this is only half-way to making something of use. In this article I want to explore a variety of craft techniques I have picked up while experimenting with spinning and dying mohair. Figure 1A range of dyed, hand spun yarns. The basics – start with a quality fleece. Of course, there may be specific reasons to “do something” with a fleece but by far the most obvious is to start with the best fleece possible. Mohair has three outstanding properties – fibre length, non- felting character and high lustre. Parallel fibres allow the lustre to be displayed and when dyed, the remarkable colour properties of mohair can be exploited. So, I choose long, open, or relaxed fleece where the staples and fibres are easily separated. The second fleece (shorn before September when fibre shedding can result in tangles) and the third fleece shorn in autumn offer the best general fleece for craft. There is a saying – shear yesterday and it will be short, shear tomorrow and it will be too long. However, shearing tomorrow is probably best for craft fleece. I use staples which are 14 to 16cm long and that means fleece grown for 7 months. Fleece from show goats also offers a good starting point (as long as it’s not too long or expensive to buy). -
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.

Notes from Judith Mackenzie's Class on Spinning Icelandic Fibers
Icelandic Sheep Breeders of North America Volume 5, Number 1 Winter 2001 Article #2 Editor, Kathy Hayes Notes from Judith Mackenzie’s Class on Spinning Icelandic Fibers Susan Mongold Weaving makes the lightest fabrics. Using a brush like a scrub brush on the woven fabric after it is woven (or knitted), will produce a long fur-type nap. The tog makes very attractive rug warp. Icelandic locks can actually be separated into up to 5 different lengths and diameters. Each layer gets progressively finer as the length gets shorter. The last or finest coat (thel) is like cashmere. The shortest undercoat, or bottom coat, the down, makes a perfect lace yarn. Lace is best made from a 2-ply yarn as the undulated surface of the 2-ply yarn helps to lock or hold the stich in place. A rounder, smoother 3-ply yarn has a smoother and more slippery surface and will not hold the pattern as well. In order to have the fibers slip easily in the spinning process, spin from the tip end of a lock, then ply from the butt end and knit from the tip end. This will give the easiest spinning experience as you are taking advantage of the lay of the scales on the wool fibers. The most important thing in a spinning fiber is the “hand.” hand is the soft silky feel of the fiber to your hand or how it feels when you handle it. It has little bearing on the fiber diameter. Even a very fine fiber can have a rough hand, while a coarse fiber can have a nice hand.
