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. -

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. Stylesight explores Baruffa Group’s finest wool yarns for first-class sweater knits, cut-and-sew jersey, and wovens. Vogue Australia December 2012 / Elizabeth Debicki in wool, on location at Haddon Rig, a Merino wool farm in New South Wales. With seductive, magnetic charm, lighter weight but often still densely constructed wovens and knits are key on men and women's runways and at textile trade shows. Wool—traditionally a winter fiber—evolves with cutting-edge superfine qualities from 150s and 180s up to 250s.

Ben Ameur2 1Textile Engineering Laboratory, University of Monastir, Monastir, Tunisia 2Technical Center of Creation, Innovation, and Supervision in Carpet and Weaving, Tunis, Tunisia Abstract This experiment was aimed to identify wool quality of Tunisian sheep breeds. Fiber characteristics of different ages and various sheep breeds were studied. A total of 84 sheep were used in this study. Results show that the factor 'breed' had a highly significant effect on all controlled parameters accept scoured yield and fibre length. Breed was the most important factor. By conducting well-planned sorting, “Fine Queue of west” sheep breed can supply the wool needed for textile industries. The wool of other sheep breeds can be used in handmade carpets.

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. -
