Amini Guide 1 02 Yarn processing CARPETS Amini Guide 02 Yarn processing 2 The carpet weaving phase is preceded by a series of yarn treatments ranging from carding to drying. The goal is to make the material as homogeneous as possible, so that it features such uniform characteristics as resistance, cleanliness, color and elasticity. Carding (3), Spinning (4), Dyeing (5) Amini Guide 02 Yarn processing 3 Carding This is the processing phase where short fibers are untangled and spread out. Although today this is mostly done by mechanical carding machines, in some artisan laboratories this ancient technique is still performed by hand with tools known as “combing cards” used to comb the fibers between two large brushes with metal tips. The result is a thin flap called ‘card web’, later carved into thin strips, called ‘wicks’, and wrapped onto a beam. Each wick gives rise to a carded thread. Amini Guide 02 Yarn processing 4 Spinning Spinning is the twisting together of drawn-out strands of fibers to form yarn, and is a major part of the textile industry. The oldest spinning tools are the distaff (rock) and the spindle. The distaff is a staff, held under one’s arm while using a spindle. Fiber is wrapped around the distaff, and tied in place with a piece of ribbon or string. The spindle is a straight spike used for spinning, twisting fibers into yarn. Amini Guide 02 Yarn processing 5 Dyeing Dyeing is the application of dyes or pigments on textile materials with the objective of achieving color with desired fastness. Dyeing is normally done in a special solution containing dyes (soluble substances of organic origin), and particular chemical material. Dye molecules are fixed to the fiber by absorption, diffusion, or bonding. The variety and continuous enlargement of the color range, achieved over 50 years of experience, ensure that the dyeing phase remains one of Amini’s main strengths. www.amini.it.

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).

They had a chiton, which probably involved a certain amount of real sewing, although most of the needlework done by Greek women was in the form of embroidery. The spinster continued to feed tow from the distaff into the growing length of yarn until the spindle reached the floor.

Greek and Roman Textiles and Dress Writer By merging the study of Greek religion and the study of textiles, the current study illustrates how textiles are, indeed, central materialisations of Greek cult, by reason of their capacity to accentuate and epitomize aspects of identity, spirituality, position in the religious system, by their forms as links between the maker, user, wearer, but also as key material agents in the performance of rituals and communication with the divine.

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.

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.

Need for Lap Preparation
Need for Lap preparation: The combers are fed with a small lap produced by combining several slivers. The raw material delivered by the card is unsuitable for combing as regards both form and fiber arrangement. If card slivers were just combined and fed to the comber, true nipping by the nipper plates would occur only on the high points, with the risk that the nippers could not retain the less firmly compressed edge zones of the slivers asshown in the below fig. This is because the slivers are not flattened. The fibres could then be pulled out as clumps by the circular combs during combing operation. A sheet with the greatest possible degree of evenness in cross section, with uniform thickness is therefore required as in-feed to the comber. Effect of fibre presentation: The fiber arrangement must also be taken into account, i.e. in this case the disposition of the hooks. If the comber is to straighten hooks, as it is intended to, then the fibers must be presented to it with leading hooks. The carded slivers have trailing hooks as the majority hooks (more than 50%) as the sliver emerges out of the calendar rollers in the carding machine. Each time the sliver is packed in a can and taken out, the majority hooks change. For example, as the sliver is withdrawn from the card can, the original trailing hooks (as the sliver went into the can) are now counted as the leading hooks as can be seen in Fig. Hence, at this stage majority hooks are the leading hooks.
