• Softest and fineness of all the wool types • Fine crimp • natural color is a bright white • 2 1/2 – 4 inches staple length • High grease content • Good elasticity • Excellent loft • Difficult to spin for beginning handspinners, because of the softness and short fibers • Good felting wool • Works best if spun fine. Record grease fleece weight and staple length of each fleece at shearing. If possible, obtain clean fleece weight. Rank fleeces according to weight of fiber produced and staple length. If possible, rank sheep within a given grade of wool, within a given age classification, and within a group in which the number of lambs raised is known.
achieved by increasing staple length and/or the number of fibres. Anecdotal evidence indicates many of these clips are discounted ( cent/kg for mm vs 80mm staple length wool of 18 microns in /2; AWEX Market Reports) due to their long staple. Traditionally, fine wool flocks have had a staple length of 70 -. fineness, staple length, crimp, color, and other quality elements, were made available for use in selling the wool. Data on sales show that much of the price differences for quality quoted in Boston was re- flected in prices of these lots to producers. Differences in yield, fineness, staple length, and staple crimp were among the most signifi-.
The introduction of the Fibrograph (fiber length) and micronaire (fiber fineness) instruments, and in the s, the application of high-volume instrument (HVI) measurements to cotton classing, and the measurement of wool fiber diameter, diameter distribution, and curvature by Laserscan (Glass et al., ), meant easier examination of the. Note 1 — The determination of fiber length of wool is covered in Test Method D, Test Method for Fiber Length of Wool in Scoured Wool and in Card Sliver, the staple length of grease wool is covered in Test Method D, Test Method of Sampling and Testing Staple Length of Grease Wool.

Additional Physical Format: Online version: Measuring wool by staple length recorder. Washington, D.C.: U.S. Dept. of Agriculture, Agricultural Marketing Service. This length is known as the Hauteur (fibre length in the Wool Top).
In addition, the average strength of staples is important in assessing how well the wool will perform during processing. Research has shown that Hauteur is closely correlated with the average Measuring wool by staple length recorder book Length and Staple Strength of the greasy wool measured prior to processing.

Following length measurement, the staple is picked up between twin rubber belts and fed to the strength section. The tip of the staple is gripped by one jaw and the base by another jaw and then the staple is broken and the peak force is recorded in newtons. The length of staple gripped by the jaws is approximately 20 by: 1.
Objective measuring. notable greasy wool weight, clean wool weight, staple length and wool quality." Inthe Hacker family's Roselea Poll Merino stud won the strong wool ram ribbon with. fleece wool trade fleeces A micron (micrometre) is the measurement used to express the diameter of wool fibre.
In Australia before being auctioned, all Merino fleece wool is objectively measured for micron, yield (including the amount of vegetable matter), staple length, staple strength, and sometimes color and comfort factor. AWTA Wool Testing provides independent and objective wool certification services.
AWTA Wool Testing's major services are sampling, testing and certifying the yield, fibre diameter, vegetable matter content, staple length and staple strength of greasy wool before it is sold. Wool length - management tips. Woolgrowers can manage frequency of shearing, breeding and nutrition to control staple length.
Staple length is unlikely to be altered in isolation of fleece weight, unless targeting a market with a specific length requirement that differs from average. On exception is lamb shearing. Use of measurement in greasy wool commerce One just has to look at a greasy wool sale catalogue today to see the importance of greasy wool measurement in the selling system.
Approximately 80% of sale lots are now sold with greasy wool measurements, of mean fibre diameter, yield, length and strength. This staple was too long for the amount of paper, which has caused the staple to tear the paper and be crushed flat.
These staples were the correct length for the job and have formed a perfect dome. You can see that the end of the staple just touches the paper. When using the correct size of staple, you get a much neater finish to the front. With the advent of staple measurement of raw wool it was the Almeter values of hauteur and CVHa that were used as the most commercially relevant top measurements to predict.
This history and dominance has had implications for the prediction technology used today as well as the development of new length measuring instruments. A micron is the measurement used to express the diameter of wool fibre. Fine wool fibers have low micron value. Fibre diameter is the most important characteristic of wool in determining its value.
Every fleece comprises a very wide range of fibre diameters—for example a typical Merino fleece will contain fibres of as low as 10 microns in diameter, and there could be fibres with.
Staple length in focus with a shift to six-month shearing The Kensit family has increased wool cut and staple length, while improving lamb survival. Test. A team of Texas A&M AgriLife Research scientists at San Angelo is evaluating the new FibreLux and comparing its results with that of the OFDA, which has been used for several years and has the.
Length of Staple Affecting the System of Manufacture: In most cases, length will decide the purpose for which the wool can be utilized and also the most suitable method of treatment to be adopted. With fine wool, length often determines whether a wool will be acceptable to the worsted or woolen system of processing.
Wool is the textile fiber obtained from sheep and other animals, including cashmere and mohair from goats, qiviut from muskoxen, hide and fur clothing from bison, angora from rabbits, and other types of wool from camelids.
Wool consists of protein together with a small percentage of lipids. In this regard it is chemically quite distinct from the more dominant textile, cotton, which is. Staple length is measured from the base to the tip of the unstretched fiber.
Longer-stapled wools are more valuable. Length also adds more weight to the fleece than any other single characteristic. Strength is another important aspect of staple length.
Strength determines wool's ability to withstand vigorous cleaning and manufacturing. 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 classing is done by a wool classer. 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.
processed length • Staple Length Variation (CVL). • Barbe length reduced by 1mm for every % increase in CVL • Vegetable Matter • Generally significant impact on Barbe length but NZ wool generally has a limited (low) range of VM. • Position of Break (mid breaks) • Increasing mid break % gave reduced barbe (10% increase in.
The staple length of the wool is the length of the staple, and highly correlated with mean fibre length in the top (hauteur). Staple length generally determines the end use of wool, that is, whether it will be used in weaving or knitting.
The longer wools, generally around 51 mm and longer and called combing types, are processed to worsted yarn.

Then, if you crossed that half blood lamb with another sheep the offsring's wool would be called a 3/8ths blood fleece, and so on.Measuring wool by staple length recorder / (Washington, D.C.: U.S.
