Determination of Dehairing, Carding, Combing and Spinning Difference from Lama Type of Fleeces
International Journal of Applied Science and Technology Vol. 2 No. 1; January 2012 Determination of dehairing, carding, combing and spinning difference from Lama type of fleeces Franka1, E.N., Hicka, M.V.H. and Adotb, O. a.- SUPPRAD2 Program, Catholic University of Córdoba, Argentina b.- SUPPRAD Program. Habitat Foundation, Buenos Aires, Argentina Abstract Mixed fleeces as Llama fleeces, require a special textile process known as dehairing. This process behaves differently according to the Lama type of fleeces dehaired. Dehairing generates structural modifications on textile raw material as it eliminates the longer and straighter (coarser) fibres. This has a marked effect on the following worsted or woolen spinning processes. This work was designed for to test these effects with the objective to report how the type of fleeces affects dehairing, worsted or woolen combing and spinning performances. From a textile behavior point of view, a higher fiber diameter variation was detected in double coated fleeces than in luster fleeces. Luster fleeces have a lower bulk potential than double coated fleeces and a lower comb yield due to the higher dehairing effect. It is also this type that produces less ends protruding from the yarn, which may account in part for their diminished prickle effect. Key words: Lama fibre, textile trials, bristle, prickle, coarse fibres. 1. Introduction A characteristic peculiar to the fibre of South American Camelids (SAC) is the presence of a mixed fleece. This is the reason for their textiles processing requiring „dehairing‟ to achieve a superior quality product, because this process consists in the removal of the coarser fibers (Russel, 1990). -

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. -

An HJS Studio Tutorial: Spinning Silk Caps I am proud to welcome Carol Weymar, a self-taught spinner and dyer of silk caps. I was much struck by the beauty of her work when I saw her website, so I asked her to write an ar- ticle, as silk is something I have no skill spinning. I hope you'll be as inspired by her expla- nation as I was! About Silk Caps Silk caps are made from cultivated cocoons that have been degummed and stretched over a frame shaped like a bell. They consist of a number of extremely thin layers; each layer is one cocoon. A cap "bell" is roughly two dozen caps, weighing about a pound altogether, which are fastened together at their tops and covered by one large cap whose edges are drawn out and tied together at the bottom to make a neat bundle. Cap silk is one of the most underrated types of silk available to the handspinner. It has its quirks, certainly, but mastering this form of silk is well worth your effort. It displays the beau- tiful luster of all its sister silks, but has the advantage of being a nearly continuous fiber. This means you can spin it to a very fine thread and it will be strong. It makes an excellent warp. It is very versatile; you can spin it into beautiful yarns, you can draw it into fine roving and knit or embroider with it in its unspun form, and you can blend it with other fibers to add bright color and gleaming highlights. -

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. -

7. Wool Combing
7. Wool Combing Errol Wood Learning objectives On completion of this topic you should be able to: • Outline the objectives of wool combing • Describe the design of a typical rectilinear comb • Explain the steps in rectilinear combing – feeding, initial combing, final combing and drawing off, and sliver formation • Discuss the means by which noils are removed, and the balance required in setting the amount to be removed • Explain the purpose of re-combing • Calculate: tear ratio, noil(%), romaine, regain and combing production • Discuss the factors that affect the combing quality of fine wools Key terms and concepts Combing (Nobel and rectilinear), nips per minute, doublings, noils, finisher gilling, packaging, re- combing, tear, noil(%), romaine, percent fibres less than 30 mm, combing production. Introduction to the topic Wool combing is a comprehensive term when used in its widest sense, and it embraces all the operations carried out in a topmaking plant. It includes the processes of raw wool scouring, drying, carding, backwashing and preparer gilling. Then follows the actual combing operation and the sequence of topmaking processes concludes with two gilling steps called top finishing (or finisher gilling). Combing is not included in the semiworsted or woollen processing routes. Wool combing, the single process, is indispensable in the manufacture of a worsted yarn. The card has disentangled the fibres in the mass of scoured wool and has mixed them in a roughly parallel formation. However, during the carding process many fibres will have been broken, and the card sliver will consist of a variety of fibre lengths. Some vegetable matter will have been removed but fragments remain.
