Once alpaca fleece is in the bag, what is it worth? The textile manufacturer could not care less whether the fleece available for sale came from a prize winning stud or the herd’s ugly duckling. Understanding what qualities the buyer desires most is the key to getting maximum value from alpaca fiber production.

All natural fiber falls into one of two categories, carpet or apparel. Carpet is coarse, apparel is fine. Apparel fiber is more scarce than carpet fiber and sells for considerably more money per unit of measurement on the international market.

The textile market is dominated by sheep wool. All other animal fiber, including alpaca, is known as “specialty fiber.” The results of processing trials conducted by fiber experts Bray, Long, and Van Bergen rated mean fiber diameter as the most important quality of sheep wool immediately affecting its value for manufacturing purposes. Their studies rated the relative value given to various fiber properties as follows:

Relative Importance
Property* Study 1 Study 2
Fineness (mean fiber diameter) 65% 80%
Length 15% 15-20%
Tensile Strength 10% Only important when present or absent to an abnormal degree
Remaining properties 10%
* Color was not considered in these studies

According to Van Bergen and Lang, the reason fineness impacts price is due to its effect on a yarn’s “spinning limit,” which means that, at any given count of yarn, the finer the fiber, the greater number of fibers in a cross section. This, in turn, leads to a more uniform yarn diameter, greater yarn strength, and greater softness of handle.

Soft garments which can be worn next to the skin are most expensive. Cashmere, with its soft, seductive feel, sells for high dollars in exclusive shops. Why is cashmere always soft and wool often itchy? Fiber fineness.

Over 30% of American consumers surveyed claimed to be allergic to wool. These same people can wear cashmere or alpaca with no adverse reaction. The International Wool Secretariat and CSIRO, the Australian research organization, with its wool technology and animal production divisions, were extremely concerned by the perception that wool commonly caused allergic reactions.

Extensive research has identified the cause of the allergic reactions in consumers who wore wool. The research began by administering common tests for allergic reactions. This involved grinding wool to a fine consistency, suspending it in liquid, spreading it on the allergic consumers and pricking the skin with a needle. The result was that consumers, originally thought to be allergic to wool, didn’t react.

What was finally found to be the cause of this so-called allergic reaction to wool? Fiber diameter. The prickle factor was guilty; the coarser the fiber, the more severe the “allergic” reaction.

Researchers found that coarse hairs extending from the yarn or fabric prick the skin and stimulate the pain receptors, thereby causing redness, irritation, and itching. Once fiber diameter was identified as the culprit, studies were done to decide at what mean diameter prickle occurred.

Fiber that averages 21 microns or less tends to be soft to the touch. Fiber with a “coarse edge” over 30 microns almost always itches. Yarns that contain more than 5% fiber over 30 microns create garments that only fleas could love.

Consumers, who previously claimed to be allergic to wool, experience no negative reactions as long as the average micron count of the garment they are wearing does not exceed 21. Further research has conclusively proven that any fabric which is made of any fiber (man-made acrylic, hair from cashmere goats, etc.) averaging more than 21 microns causes pain on the skin and a so-called allergic reaction (see the attached diagram).

Alpaca is no exception. Coarse alpaca itches. Fine alpaca feels smooth and silky next to the skin. That’s why fiber diameter is by far and away the most dominate value affecting fiber prices.

Bruce McGregor is a senior scientist with the Victorian Department of Agriculture in Australia, specializing in improving the production and quality of specialty animal fibers. He wrote an extensive article for Alpacas Australia (issue 13, 1995) entitled Alpaca Fleece Development and Methods of Assessing Fibre Quality. His article ranked, in order of importance, the qualities of alpaca fleece that processors have valued over many years, as follows:

1. Fiber diameter
2. Fiber length
3. Fiber color
4. Freedom from contamination
5. Degree of medulation

McGregor does not include tensile strength as a quality affecting value. The strength of alpaca fiber is so superior to other natural fibers, such as wool, that it is not considered an issue in pricing.

Alpaca fiber’s staple length is important. Length commands a premium in the market. This is because length increases the manufacturers’ ability to spin finer and stronger yarns for weaving. But McGregor still concludes that “Markets usually discriminate against length to a lesser degree than fiber diameter.”

The best way to increase uniformity is to reduce the average micron count. A finer fleece has less standard deviation. This is just another reason why micron count is the primary determinate of a fiber sale price.

Another reason for fiber diameter to be the dominate value is that the fiber diameter distribution (FDD) can not be accurately measured on large sale lots. There is too much variability from one fleece to the next. Furthermore, textile manufacturers almost always combine fiber from several lots to make tops. They purposely mix fiber with various micron counts, strength, and length to create a top that meets a certain specification. Finally, the cost of measuring standard deviation in large lots is prohibitive.

There is considerable research which establishes the fact that a more uniform fleece is more “spinnable.” A fleece with a co-efficient of variation that is 5% less than a fleece of comparable micron will spin a yarn that performs as if the fleece is one micron finer.

The most dramatic evidence of the influence of micron count on price was the million dollar bale sale which occurred at the annual Australian wool sale. Each kilogram in this one bale of sheep fleece sold for $10,030 Australian. The entire bale made up of 100 kilos of fine merino sheep wool sold to a Japanese textile manufacturer for $1,030,000. The fleece, the finest sheep wool ever tested, averaged 13.8 microns.

Alpaca Breeding for Maximum Value

Any business needs a plan. It really doesn’t matter whether you are manufacturing cars, growing corn, or raising alpacas. See How to Buy, Breed, and Succeed in the Alpaca Business. You need a plan. A sound plan begins with an inventory of your product’s strengths and weaknesses. If you believe that the ultimate goal of the alpaca business is to produce fiber as opposed to pets, please continue reading.

Alpaca fiber is known as a specialty fiber. In fact, every fiber, other than sheep wool, is known as a specialty fiber. Wool is grown world wide in huge quantities – 432,000 tons in 1994 alone (source: Wool International). Specialty fiber production totals about 142,000 tons per year. Of this, approximately 4,000 tons is alpaca. Scarcity or rarity is one way alpaca fiber competes.

R.C. Couchman, a well known Australian fiber expert, authored an extensive series of articles for Llama Life about alpaca fiber. He made the following point many times over, “Fineness is what specialty fiber is all about.” Alpacas shouldn’t compete with sheep, which produce large volumes of coarse fiber, when they have an excellent potential to produce fine, soft fiber and receive a significant price premium upon sale.

The business plan at Northwest Alpacas is based on breeding alpacas which produce fine fiber in high volumes. This strategy should enable us to compete effectively at several levels: 1) the textile market, which pays a significant premium for fine fiber; 2) with sheep wool, the bulk of which is coarse; 3) the South American alpaca fiber producers who sell their fiber based on volume, not fineness; and 4) with other ranches selling bloodstock that produces alpacas having coarse hair and lower fleece weights.

Alpacas are not another exotic pet fad - they produce exquisite fiber that has been revered for centuries. In ancient South American cultures, Alpaca fiber was prized on par with gold! The fiber is prized to this day, worldwide, and the animals themselves are very easy on the environment. Many believe that alpacas will be the next “green” sustainable fiber source.

As you would expect, fiber quality varies greatly among alpacas. There are two types of fiber Huacaya (fluffy, teddy bear) and Suri (dreadlockey). Huacaya fleece is usually crimpy, and grows straight out from the alpaca’s body, they are the fluffy ones. Suri fleece has a long, silky look, hanging straight down from the alpaca’s body. Suri and huacaya fleeces each have desirable characteristics making them highly sought after for different uses in the textile industry.
