Through its natural crimp, it creates miniscule air pockets, which help regulate temperature. Terms & Conditions, CRC for Premium Quality Wool: 1993 – 2000 An Evaluation, A chain is only as strong as its weakest link. A fine wool like Merino may have up to 40 crimps per centimetre (100 crimps per inch), while coarser wool like karakul may have less than one (one or two crimps per inch). c/- P.O. Relaxation shrinkage is an irreversible change in fabric dimensions (expansion or shrinkage) that occurs only once when a fabric is first immersed in water (without agitation) and then allowed to dry. The arrangement of the cells causes the ‘crimp’ (wave) in the wool fibre and traps air (providing insulation), which produces wool fabrics that keep us warm during winter. So, is it the crimp or is it the staple length that gives us the result that we see in hauteur? Finer the wool the more will be the crimps in it. It is taken into account when the sheep are bonitized and the wool is classed. Woolcheque uses a combination of objective and subjective wool measurements and characteristics to price wool. An associated question is whether a breeder can maintain a particular crimp frequency and yet make acceptable changes to other characteristics of economic (and processing) importance. Sheep with fleeces that were broader crimping than they thought desirable for any flock were culled and so were sheep that were too highly crimped. In the past, the task of spinning usually was the job of unmarried females – they became spinsters. Crimp promotes the protection of the fleece from ingress of mechanical impurities and atmospheric precipitation. This results in the entanglement of the fibres as they move under mechanical action in water (as occurs in Some of the qualities a wool classer examines when classing wool are: Breed of the sheep: Shedding breeds will increase the risk of medullated or pigmented fibers. The impact of this is that selection within a fine wool flock for increased fleece weight will produce animals in subsequent generations with lower crimp frequency. Since moisture does not remain on the surface, woollen fabrics tend to feel dry and comfortable even in damp weather. AWEX-ID covers subjective characteristics. Sheering is done by hand, but the manufacturing of wool fabric is done by machine. Fleece is a ball of wool taken from a single animal in a shearing. Aside from premium next-to-skin apparel, wool can be used in industrial applications such as thermal and acoustic insulation or in pads to soak up oil spills. The ortho-cortex and para-cortex cells form the core of the wool fibre. Textile School incorporates knowledge associated to textiles right from fibers to its end usage including textile processes, trade-offs, know-how and textile standards. Merino fiber is know for its high frequency of crimp. The crimp in the fibre allows wool fabrics to hold air and thereby retain heat. Figure 1b The relationship between crimp frequency and staple length showing that the lower crimped wools are associated with longer staples. Wool mostly comes from sheep but also from alpacas, camels, and goats. 1966 57(3). Crossbreed: A sheep or the wool from a sheep resulting from the breeding of two difference breeds. Crimp — How important is it in modern wool? Breeds found in Texas and California produce fibres 2.5 inches long. A sheering specialist can sheer 200 sheep in a day. Textile School - a knowledge-base repository of textile articles. In general, these results show that up to the topmaking stage lower crimped wools produce slightly longer fibres and have lower processing losses than wools of higher crimp frequency. Gallagher J. R. Textile Research Journal. What is the genetic relationship between crimp frequency and other traits that breeders might consider important in their flocks or in the flocks of clients? Wool scale. More at Textile School Scouring, washing or processing will not remove this layer. Textiles The keratin-associated protein KAP8-2, is present in wool from sheep. This UK breed is classified as mountain and hill. The differences in the chemical structure of the various fibres mean that different classes of dyestuffs are required to cover the range of fibre types. One of the many raw wool attributes measured on the individual fleeces that formed the processing batches was crimp frequency. All Rights Reserved. Moisture content is the ratio of the mass of water to the mass of water plus wool expressed as a percentage. In this replicated experiment, we investigated the impact of cashmere in blends with superfine wools on the mechanical properties of single jersey knitted fabrics. Nitrogen and Sulphur) for the growth of organisms as part of natural carbon and nutrient cycles. The fiber length of 5-12 cm is used in the garment industry because this length allows the yarn to be manufactured with greater precision. But be careful: When wool is wet the fibers are weaker. They are fiber diameter, crimp, yield, color, and fiber staple length/strength. In wool, the individual fibers have a characteristic crimp or waviness that ranges from tight to loose, depending on the sheep breed. What would happen to diameter, for example? However, when we look at the genetic control, things are different. We already know that crimp frequency was used in the past as a visual indicator for mean fibre diameter. The wool fibers have crimps or curls, which create pockets and give the wool a spongy feel and create insulation for the wearer. Wool is known for its ”memory,” which is the ability of fiber processed into textiles to bounce back to its original shape. The highest quality wool comes from the sides, shoulders, and back. This article is based on a report that he presented in the CSIRO Fine Wool Newsletter. The fiber length ranges from 3.8-38 cm. The Field Guide to Fleece: Wool Characteristics Learn about different wool characteristics — from fiber length and diameter to crimp. Australian Wool Education Trust Wool Also Keeps You Cool. All lots sold through the auction system by AWEX are assigned an appraised style, from inferior (7) to choice (1). The move to nylon woolpacks does not Next, the wool is carded – that means brushing the wool to straighten the fibres. Now let us see what proportion of those differences in a typical fine wool flock is due to the effects of genes that will influence the performance of the next generation. The effect of variation in KRTAP8-2 on wool traits was investigated in Chinese Tan sheep. Jute Fiber – the natural cellulose bast fibers from plants or…. Wool is graded for fineness and length. Is there significant genetic control of crimp frequency? The characteristics which a wool classer would examine are: Breed of the sheep: Shedding breeds will increase the risk of medulated and/or pigmented fibres. We were particularly interested in the hauteur, or mean fibre length in the top because it is has a big influence on the prices paid for wool tops. Having said that, the term “tropical” refers to a fabric’s weave as much as its weight. Alpaca is often criticized for having inadequate memory and, as a result, is often blended with 6% to 20% wool to increase memory. What characteristics determine what is wool 's value? Relaxation shrinkage is caused by the release of temporarily set strains imposed on the fabric in dry finishing and can be minimised by suitable finishing routes. Characteristics of Wool Fibers. 7. At the disposal stage, natural fibres such as wool reduce the impact of the textile industry on pollution and landfill build-up. This is carried out by examining the characteristics of the wool in its raw state. The wool produced is approx. Wool absorbs perspiration; thus it keeps a layer of dry air next to the skin which, in turn, helps to hold in body heat. II. Distribution of Grade or Wool Fiber Diameter. Are measured in microns (μm), which are one one-millionths of a meter. Blends of different synthetic fibres with wool for suiting materials are increasingly important. This microscopic view shows us why wool is special. It therefore comes as a bit of a shock to find objective evidence that shows the association between crimp frequency and mean fibre diameter is essentially zero. North Melbourne Victoria, 3051 In the thin and semi-fine wool distinguish three basic forms of twists: normal, flat and high. This information allows us to relate the average crimp frequency of a processing batch to the subsequent performance of that batch through to top stage. Synthetic fiber manufacturers have attempted to simulate these natural characteristics through mechanical processing with satisfactory results. This result in fabrics that are more appropriate in warmer conditions. The association between fleece weight and crimp frequency is slightly more complex. First in the west — New students graduate in Wool Science, Phil Hynd is new head of Animal Science in Adelaide. This site uses Akismet to reduce spam. Wool classing is done by a wool classer. Cheviot . This means that selection within a flock or bloodline for lower mean fibre diameter alone will not change crimp frequency. This crimp may be introduced mechanically by passing the filament between gearlike rolls. The roving is spun into yarn that is then woven into cloth. It was one of the first fibers to be spun into yarn and woven into the fabric. What do the processing results from the Fine Wool Project show us? Wool is a protein fibre that has scales and crimp that make it easier to spin into yarn because the fibres interlock with each other rather than slide loosely against each other (as in the case of cotton which is made of cellulose). Fleece: The wool from a single sheep in the shorn grease state. Once done by hand, these days a carding machine passes the wool through a series of rollers covered with wire bristles. machine washing). But not all wool is equal – even when it comes from the same animal. Figure 1a. Find out about different sheep breeds and their characteristics in our latest blog by World of Wool. Apparel Merino wool has 30 crimps per inch while coarse wool has one or two. The air trapped between the fibers provides natural insulation and wears well in high traffic areas. And because of the inner moisture, wool is naturally flame resistant. The crimp of wool, or the frequency of waves in a wool staple, has been a vital part of the selection of Merino rams and ewes from the early days. More than 200 batches representing the pooled fleeces of the progeny of individual sires have been processed through to tops at the Geelong research mill of CSIRO’s Division of Wool Technology. The fleece is a bright white with good crimp and soft handle and is very even. Studies have been conducted over several decades on crimp frequency and processing efficiency by the South African Wool Research Institute and by CSIRO Division of Wool Technology in Australia. As Figure 1a clearly shows, when crimp frequency increases, hauteur decreases. Wool style is a ranking based on a subjective appraisal of the overall look and feel of a wool lot and considers evenness of crimp along the length of a wool staple, the extent of tip damage, dust content and penetration, colour and lustre. The wool fibers have three-dimensional crimps, 25 waves per 10 cm in fine fiber, and 4 waves per 10 cm for coarse fibers. In a strand of yarn, it enables the fibres to lock with one another. The surface is a series of overlapping scales of protein, pointing toward the tip. Crimp is a multi dimensional structure and how the crimp is expressed is determined by genetics (cortical cells- bilateral structure), amplitude, crimp frequency and micron. The eco-credentials of wool are enhanced by its long service life and suitability to be recycled to new textiles for clothing, resilient upholstery or products that call on its natural resistance to fire and temperature extremes. Save my name, email, and website in this browser for the next time I comment. Felting: The matting together of wool fibers. Wool’s surface repels water. This difference is utilised in carbonising wool to remove excessive cellulosic impurities, such as burr and vegetable matter. 150 – 158. Before we had equipment that could measure mean fibre diameter accurately, crimp frequency (or quality number) was the most common means of estimating mean fibre diameter. The absorbed moisture also holds down static electricity. In addition, many sheep classers were firmly convinced that fleeces should be true to a bloodline or stud “type” and, to be true to type, fleeces had to have a particular crimp frequency. In the wool industry, a good well-crimped fleece is said to While wool is grown to keep an animal insulated, it is not the same as hair or fur. Wool is ideal for cool weather garments such as sweaters. Wool products labelling Act permits the word “wool” to be used for fibres from sheep, Angora or Cashmere goats, camel, alpaca, llama, and vicuna. Crimp is the natural wave formation found in the Huacaya fleece. Some wools are better suited for rugs and others for fine lace. Cool Wool uses what’s known as an “open weave,” which, as the astute gentleman may have guessed, means it allows body heat to escape, while letting outside air in. Contrary to popular belief, not all wool is rough and itchy. A ewe, or female sheep, can produce up to 15 pounds of wool. Fiber widths. The process is called sheering. Australian Merino wool is 3-5 inches long. Flame resistant (wool usually extinguishes itself when the source of flame is removed), Weaker than cotton or linen, especially when wet, Fibres range from one to fourteen inches long, Most valued for its textured appearance and warmth, Springs back into shape after being crushed, An excellent insulator as woollens (80% air), Absorbs moisture which is held inside the fibre (the wool will still feel dry even on a humid day), Quality of wool varies with the breed of sheep, Does not attract dirt or static electricity. The inner core does absorb moisture – so much so that wool can absorb almost double its own weight in water and still feel reasonably dry. This characteristic makes wool a versatile all-season fabric. If we look at the relationship between crimp frequency and staple length in Figure 1b we get an identical relationship. We'll assume you're ok with this, but you can opt-out if you wish. Wool Characteristics: aa043097. The Fine Wool Project of the Wool CRC’s Program 1 is throwing light on these questions by giving us information about a number of issues related to crimp frequency: First, let’s look at variability. Wool is resistant to acid, whereas cotton and cellulose are severely damaged if exposed to acid. On the face of it, it looks as though lower crimp wools are clearly better than highly crimped wools. In other words, is crimp related to factors that determine processing yields and the economics of processed products. Does it still have a place in classifying wool? This conclusion applies only to fine wool flocks. Felting shrinkage is a form of shrinkage unique to wool and wool-rich fabrics and is caused by the scales on the surface of wool fibres that have a ratchet-like action allowing preferential movement of the fibre in the direction of the fibre root. The results of these unique trials will let us predict with confidence the. Fiber At ambient humidity, wool will contain 10 to 15% by weight of water and up to 35% water at high relative humidity, which is more than most other fibres. Journal of the Textile Institute Transactions. Of the major apparel fibres, wool is the most reusable and recyclable fibre on the planet. The breathable “air pocket” characteristics of wool mean that sweat doesn’t weigh down your insulation layers, which causes you to feel consistently warmer the more you sweat. Fibre crimp affects wool’s properties The crimp in wool fibres makes it soft and springy to touch. The sheared wool is called raw wool and since sheep don’t take showers, it must first be cleaned. Animal Science (1975) Wool characteristics of Iraqi Awassi sheep. processing consequences of different selection strategies. Wool grows permanently crimped and this natural crimp gives the fiber bulk and allows it to absorb noise. That is, longer staples have a lower crimp frequency. AcceptRead More, Wool fiber – Basics, Characteristics, & Properties, Characteristics of Wool Fibers and Products, Summary of Characteristics of Wool Fibers. Progeny of sires (and dams) with the highest clean fleece weights tend to have the lowest crimp frequency. Wool always absorbs moisture from the atmosphere of greater humidity and releases it to the drier environment as it creates a balance in moisture conditions. This water is incorporated in the internal structure of the fibre and, therefore, is hardly noticed by the wearer. necessarily prevent contamination; however, as the chemical structure of nylon is similar to wool, it absorbs wool dyes and this makes any contamination less obvious. There are two major sources of shrinkage in wool-containing fabrics, which may be encountered during laundering: relaxation and felting shrinkage. Wool is possibly the oldest fiber known to humans. It is the same whether we look within a flock, or a bloodline, or even a strain of Merino. The amount of crimp corresponds to the fineness of the wool fibers. The only way to Do we scrap it entirely or is it important in the processing of wools of any particular “type”? remove this layer, if required, is by chemical treatment. Although the wool fibre can readily absorb water vapour from the air, a garment made from wool will be water repellent to some extent. So they attempted to create uniformity in crimp frequency. The wool fiber properties particularly the fineness and crimps of Menz, Dorper and 50% Dorper sheep of different parts and age categories are significantly different. Finer fibres with more crimp such as Merino create fabrics that drape better than coarser fibres. Polypropylene and polyethylene do not absorb the dyes used to colour wool so any wool pack contamination from these fibres in the final product will appear obvious. Fabric How much does crimp frequency vary between sheep (take the frequency at the midside as the average of the sheep)? The crimp of wool, or the frequency of waves in a wool staple, has been a vital part of the selection of Merino rams and ewes from the early days. The site is intended for all spectrum of users to learn and share the textile knowledge from a single platform. Finishing Many readers have asked for a smaller book that they could carry with them … Dr Ian Purvis, manager of Program 1 has been studying crimp as part of the Fine Wool Project and reflects on its changing importance in modern wool science. The fiber diameter measures the width of the fiber. This property enables wool to act as a buffer against sudden environmental changes, for example, excessive perspiration during exercise or changes in climatic conditions such as going outside from an air-conditioned room. Regain is the ratio of the mass of water to dry wool expressed as a percentage. This absorbency also gives wool its natural resistance to wrinkles. Evaluation of New Zealand low and high crimp Merino wools. Crimp: The natural waviness of the wool fiber; it varies with the diameter of the fiber. I will be presenting further data in The Wool Press as they become available. This is measured by the heritability, and crimp frequency is moderately heritable (approx. However, we have done the calculations and despite concerns about changing crimp frequency in fine wool flocks, we conclude that selection that is focused on the major traits of economic importance within a flock fleece weight and diameterwill result in only very small changes over a period of, say, ten years. Box 240 It is still the prime choice for high-quality business suits, warm sweaters, and premium carpets. Wool classing is the production of uniform, predictable, low-risk lines of wool, carried out by examining the characteristics of the wool in its raw state and classing (grading) it accordingly. wool characteristics between mobs within a flock which will require those mobs to be kept separate, however where mobs are of similar breeding and husbandry conditions the Woolclasser may choose to combine those mobs to create larger lots. Animals whose crimp varied across their body were also usually dispatched to the butcher. Two previously identified KRTAP8-2 alleles (A and B) were detected, but the frequency of B in the Tan sheep was much higher than reported previously for New Zealand (NZ) sheep. The most important use of wool is for apparel coats, jackets, suits, dresses, skirts, slacks made from woven fabrics of varying weights and knitted fabrics’. Wool from other breeds and other animals may be as long as 15 inches. Questions exclusive to textile topics and professional answers from the textile community. A.B.N. In the home furnishing area, the major use of wool is in carpets and rugs where wool is used more, cover to the carpets and warm in the rugs. If we take the nine fine/superfine bloodlines that form the Fine Wool Project flocks, and plot the average value for the hogget animals over five years, we see the differences shown in Figure 1a. It … Dr Ian Purvis, manager of Program 1 has been studying crimp as part of the Fine Wool Project and reflects on its changing importance in modern wool science. If a ram from a medium wool bloodline is used – where, of course, the average crimp frequency is very different- there will be greater changes over this period. Wool is a protein fibre that comes from a variety of animals. Crimps: Wool fibre is more or less wavy and has twisted. A ram, or male sheep, can 20 pounds of wool. Wool characteristics and processing performance of knitwear and woven fabrics. Proceedings of the ninth wool textile research conference, vol. But, if we change the crimp frequency of the flock, what would we be doing to other characteristics at the same time? Learn about different wool characteristics — from fiber length and diameter to crimp | Cross River Homes We love wool. Perhaps the biggest issue of all, these days, and certainly an important one, is the relationship between crimp frequency and processing performance. The crimp is characteristic of all types of wool fibers, except for the covering hair. These are preliminary results in a very comprehensive program but they are certainly important to producers of fine wool who are considering using crimp frequency as part of their selection strategy. The Crimp/Diameter Relationship in an Australian Merino Flock. This is especially surprising when viewed against Figure 1b the range of crimp frequency found in the hoggets from any of the flocks which is very much greater. Specialty We love sheep. In the Sahara Desert, Bedouins wear thin wool clothing to help them keep cool in the scorching heat. 12—A COMPARATIVE STUDY OF THE WOOL CHARACTERISTICS OF TWO MERINO BREEDS UNDER SEMI-ARID CONDITIONS. The majority of wool (72.8%) is used in apparel, home furnishing account for 15-45%, industrial uses 6 to 7% and exports 5%, wool accounts for 3.3% of all fibres for apparel. About wool and its properties. Wool is composed of carbon, hydrogen, nitrogen and this is the only animal fiber, which contains sulfur in addition. By Deborah Robson & Carol Ekarius That’s why we wrote The Fleece & Fiber Sourcebook. Wool fiber is the natural hair grown on sheep and is composed of protein substance called as keratin. It was one of the first fibres to be spun into yarn and woven into a fabric. This is because the surface of the fibre has a very thin, waxy, lipid coating chemically bonded to the surface that cannot be easily removed. p.T107. p.883. 25-30microns and staple length, 80-120mm. The relationship between crimp frequency and length of fibre in the processed top (hauteur) showing that the lower crimped wools produce tops with longer hauteur. II, pp. … Wool is treated with a solution of sulfuric acid and is then baked to destroy the impurities with only minimal damage to the wool. This is the key to wool’s strength. Wool has many useful properties besides insulation. Wool fibers are crimped and elastic, and they have scale, which in combination give wool it’s unique characteristics. What is the relationship between crimp frequency of a fleece and its processing potential? Wool is possibly the oldest fibre known to humans. It also adds bulk and traps a large volume of air between the fibres, giving it good insulation properties. The length varies from place to place on the animal, but it mostly varies amongst sheep breeds. Hence, these wool fibers shall be classified and graded based on their breeds to use for different applications, and also it could help to explore more on wool fiber production. Finer wools such as merino are very crimpy, with tight waves, while coarser breeds such as Lincoln have thicker individual fibers and a looser crimp. Learn how your comment data is processed. Then, they need a haircut. The amount of water absorbed by wool is usually referred to as ‘regain’. There are many different breeds of sheep, each with their own characteristics. Wool, along with cotton and to a lesser extent nylon, is a fibre that absorbs moisture from the surrounding air to reach an equilibrium, which depends on the relative humidity of the environment. In wool the finer (smaller) the diameter the higher the quality of wool. The carded fibres are gently scraped into strands called roving. Other articles where Crimp is discussed: man-made fibre: Crimping: In order for staple fibres to be spun into yarn, they must have a waviness, or crimp, similar to that of wool. Gary Robinson (right) and Phil Henry from CSIRO Geelong examine a top made from wool from the Fine Wool Project. The first thing to note is that these differences are surprisingly small. In warm, moist conditions such as in soil, wool biodegrades rapidly through the action of fungi and bacteria to essential elements (i.e. Wool’s Special Characteristics.
