ALPACA FIBRE

  

Alpaca fleece is the natural fiber harvested from an Alpaca. It is light weight or heavy weight, depending on how it is spun, soft, durable, luxurious and silky natural fiber. While similar to sheep’s wool, it is warmer, not prickly, and has no lanolin which makes it hypoallergenic. However, this lack of lanolin also prevents Alpaca fiber from being naturally water-repellent. It also has less crimp, thus making it much less elastic. Alpaca fleece is made into various exports, from very simple and inexpensive garments made by the aboriginal communities to sophisticated, industrially made and expensive products such as suits. In the United States, groups of smaller alpaca breeders have banded together to create "fiber co-ops," in order to make the manufacture of alpaca fiber products less expensive.

In physical structure, alpaca fiber is somewhat akin to hair, being very glossy. Alpaca fibre is generally coarser than wool fibre, and alpaca yarns are weaker than most wool yarns. In processing, slivers lack fibre cohesion and single alpaca rovings lack strength. More twisting is necessary to improve strength, but this reduces yarn softness.

Alpaca has generally higher medullated fibre than wool. These are fibres with a central core, which may be continuous, interrupted, or fragmented. The cells of the central core may contract or disappear, forming air pockets which assist insulation. However the higher incidence of medullated fibres in alpaca, compared to wool and mohair, can be an objectionable trait. They can take less dye, standing out in the finished garment, and are weaker. The proportion of medullated fibres is higher in the coarser, unwanted guard hairs: there is less or no medullation in the finer, lower micrometre fibres.

Good quality alpaca fiber is approximately 18 to 25 micrometres in diameter. Whilst breeders report fibre can sell for 2 to 4 dollars per ounce, the world wholesale price for processed pre-spun alpaca “tops” is only between about $10 to $24 US/kg (according to quality), i.e. about $0.28 to $0.68 per oz. Finer fleeces, ones with a smaller diameter, are preferred, and thus are more expensive. As an alpaca gets older the width of the fibers gets thicker, at between 1 µm and 5 µm per year. This is often caused by over nutrition; if fed too much nutritious food the animal doesn't get fat, instead the fiber gets thicker. Any alpaca fiber exceeding 34µ is classified as llama.

As with all fleece-producing animals, quality varies from animal to animal, and some alpacas produce fiber which is less than ideal. Fiber and conformation are the two most important factors in determining an alpaca's value.

Alpacas come in many shades from a true-blue black through browns-black, browns, fawns, white, silver-greys, and rose-greys. However, white is predominant, because of selective breeding: the white fiber can be dyed in the largest ranges of colors. In South America, the preference is for white as they generally have better fleece than the darker-colored animals. This is because the dark colors had been all but bred out of the animals. The demand for darker fiber sprung up in the United States and elsewhere, however in order to reintroduce the colors, the quality of the darker fiber has decreased slightly. Breeders have been diligently working on breeding dark animals with exceptional fiber, and much progress has been made in these areas over the last 5-7 years.

The preparing, carding, spinning, weaving and finishing process of alpaca is very similar to the process used for wool.

Types of alpacas
Suri AlpacaThere are two types of alpaca: Huacaya (which produce a dense, soft, crimpy sheep-like fiber), and the mop-like Suri (with silky pencil-like locks, resembling dread-locks but not actually matted fibers). Suris are prized for their longer and silkier fibers, and estimated to make up between 19-20% of the Alpaca population. Since its import into the United States, the number of Suri alpacas has grown substantially and become more color diverse. The Suri is thought to be rarer, possibly because it is less hardy in the harsh South American mountain climates, as its fleece offers less insulation against the cold.

History of alpacas
Alpaca have been bred in South America for thousands of years. Vicuñas were first domesticated and bred into alpacas by the ancient tribes of the Andean highlands of Peru, Chile and Bolivia. In recent years alpacas have also been exported to other countries. In countries such as the USA, Australia and New Zealand breeders shear their animals annually, weigh the fleeces and test them for fineness. With the resulting knowledge they are able to breed heavier-fleeced animals with finer fiber. Fleece weights vary, with the top stud males reaching annual shear weights up to 7 kg total fleece and 3 kg good quality fleece. The discrepancy in weight is because an alpaca has guard hair which is often removed before spinning.

History of fiber industry
The Amerindians of Peru used this fiber in the manufacture of many styles of fabrics for thousands of years before its introduction into Europe as a commercial product. The alpaca was a crucial component of ancient life in the Andes, as it provided not only warm clothing but also meat. Many rituals revolved around the alpaca, perhaps most notably the method of killing it: An alpaca was restrained by one or more people, and a specially-trained person plunged his bare hand into the chest cavity of the animal, ripping out its heart. Today, this ritual is viewed by most as barbaric, but there are still some tribes in the Andes which practice it.

The first European importations of alpaca fiber were into Spain. Spain transferred that fiber to Germany and France. Apparently alpaca yarn was spun in England for the first time about the year 1808 but the fiber was condemned as an unworkable material. In 1830 Benjamin Outram, of Greetland, near Halifax, appears to have reattempted spinning it, and again it was condemned. These two attempts failed due to the style of fabric into which the yarn was woven — a type of camlet. It was not until the introduction of cotton warps into Bradford trade about 1836 that the true qualities of alpaca could be developed into fabric. It is not known where the cotton warp and mohair or alpaca weft plain-cloth came from, but it was this simple and ingenious structure which enabled Titus Salt, then a young Bradford manufacturer, to use alpaca successfully. Bradford is still the great spinning and manufacturing center for alpaca. Large quantities of yarns and cloths are exported annually to the European continent and the US, although the quantities vary with the fashions in vogue. The typical "alpaca-fabric" is a very characteristic "dress-fabric."

A pair of Huacaya alpacas near an Inca burial site in PeruDue to the successful manufacture of various alpaca cloths by Sir Titus Salt and other Bradford manufacturers, a great demand for alpaca wool arose which could not be met by the native product. Apparently, the number of alpacas available never increased appreciably. Unsuccessful attempts were made to acclimatize alpaca in England, on the European continent and in Australia, and even to cross English breeds of sheep with alpaca.

There is a cross between alpaca and llama — a true hybrid in every sense — producing a material placed upon the Liverpool market under the name "Huarizo". Crosses between the alpaca and vicuña have not proved satisfactory. Current attempts to cross these two breeds are underway at farms in the US. According to the Alpaca Owners and Breeders Association, alpacas are now being bred in the US, Canada, Australia, New Zealand, UK, and numerous other places.

In recent years, interest in alpaca fiber clothing has surged, perhaps partly because alpaca ranching has a reasonably low impact on the environment. Outdoor sports enthusiasts recognize that its lighter weight and better warmth provides them more comfort in colder weather, so outfitters such as R.E.I. and others are beginning to stock more alpaca products. Using an alpaca and wool blend such as merino is common to the alpaca fibre industry in order to improve processing and the qualities of the final product.

In December 2006 the General Assembly of the United Nations proclaimed 2009 to be the International Year of Natural Fibres, so as to raise the profile of alpaca and other natural fibres.

HINTS FOR CRAFTING IN ALPACA FIBRE

Alpaca has long been considered amongst the finest of fibres. Indeed, the Incas called it "the fibre of the gods". The softness of alpaca fibre is unsurpassed, with a silky lustre to it. Alpaca has a good staple length and is fine, and the alpaca Southern Alpacas sell for craft use has a micron of 18 to 26 (about the same as merino wool). The first sheer from young animals is baby-soft and finest, with a micron of less than 20. Alpaca can be used wherever you would use sheep wool, and the finished article will be lighter, softer, and warmer. Alpaca has partially hollow fibres, providing excellent insulative properties whilst remaining lightweight. It also has superb strength and is hard wearing. Alpaca is 30 percent warmer than the same weight merino garment and is four times more abrasion resistant than merino.

Alpaca does not have the same "prickle factor" of wool, so once washed it is suitable for use by most allergy sufferers. Alpaca does not tear, pill, stain, itch, or create static.

Preparing Fibre
We sell clean fibre, washed and carded and ready to spin, and also clean raw fibre. Raw fibre can be spun as is or it can be washed first. Use a mild detergent and warm water, and give it two clear water rinses, in water of the same temperature. Squeeze out, and dry it on a raised rack to let the air circulate.

Raw alpaca only loses 7 to 10 percent of its weight in washing, and does not shrink when washed carefully. Put the fibre into the water — do not run water onto it. Alpaca does felt, so do not agitate it when washing.

Buy luxurious alpaca fibre direct from our herd. Fine and soft, raw or carded. Try our beautiful blends with silk and our exquisite fine yarns.

Spinning fibre
Alpaca handles and spins like fine wool or mohair. Raw fleece can be spun from either the cut end or the tip. Using washed and carded alpaca sliver gives a nice draw and is easy to spin.

Alpaca is best suited to 4 ply or 8 ply weight to maximise its attributes. Because of the smoothness of the fibre, more twist is required. Use plenty of twist on the singles, and a firm twist on the plying to form a yarn. Alpaca has less crimp, so there is not as much bulk in the yarn.

Knitting yarn
Alpaca is low in crimp, and, for knitting, blending in other fine washed fibres improves the loft and elasticity, and helps larger garments retain their shape better.

Knit so there is not much air space and knit a tension square first. Use any 8 or 12 ply pattern, triple knit, with 4.5 to 5.5 needles. Recommended needle sizes are:

4 ply 3.25 and 2.75 mm (10's and 12's)
8 ply 4.00 and 3.25 mm (8's and 10's)

In knitwear, consider using alpaca for jerseys, cardigans, baby wear, socks, gloves, scarves, ponchos, hats, jackets and rugs.

Blending
Many spinners who knit, like to add in some sheep wool. This can be done by hand-carding the two together before spinning, or spinning a single of each of the alpaca and the sheep wool, and plying them together softly. To feature the properties of the alpaca, spin them thicker than the wool single.

Alpaca contains very little oil and does not shrink when washed carefully. A greasy sheep fleece will lose weight and shrink when washed due to the cross linking and tangling of fibres. As the wool shrinks more than the alpaca, this will give a spirally effect to your spinning when washed. To avoid this, pre-wash the sheep fleece.

Alpaca can also be blended with mohair in a brushed yarn, giving a beautiful soft light yarn. Mohair will add sheen and loft and give a fuzzy look when blended on hand carders. Angora rabbit blended with alpaca is very soft, warm and luxurious.

Alpaca and silk carded together is a lovely combination and the finished yarn feels softer and shinier. Alternatively, wisps of silk applied to the carder first, on a diagonal, and then a contrasting colour of alpaca applied on top, carded only once, will give a sparkle in places to your handspun yarn.

Weaving
A yarn containing 100% alpaca is well suited to weaving. It makes a good warp when sleyed at 8 to 14 ends per inch. If you have trouble with your warp fibres clinging together, dampen them with a wet sponge as you weave. Do not beat your weft too hard.

Handspun alpaca is more effective in simple weaves so that its colour and texture can be seen. Very effective planned stripes and patterns can be woven using the natural colour shades, or you may prefer to have a more natural look by allowing different shades to appear throughout your weaving.

For a uniform colour, use several bobbins while winding your warp and two shuttles for the weft to distribute any slight colour variations.

The cloth should be finished by washing with a mild soap in hot water. Steam press while it is still damp. The full lustre of the fibre becomes more apparent after washing.

Woven alpaca is suitable for scarves, stoles, knee rugs, ponchos and bags. Set more closely, a hard-wearing cloth suitable for coats and suits can be woven. The textile can also be used for blankets, linings and upholstery. See our range of alpaca fibre and crafted products.

Felting
Alpaca fibres have small smooth scales, like human hair, and thus it is hard to grip its neighbour, which can make the felting process longer, compared to a cross-bred sheep wool. Use lots of soap and hot and cold water.

Alpaca does felt nicely by itself, very fast, like merino.100% alpaca felted hats come out lovely and soft and still hold their shape.

Washed and carded alpaca gives a nice even lay, with less chance for holes to appear. Raw alpaca fibre can be used for applying to wool felt, and could also be used for felting on its own.

Many people blend a mix of alpaca and wool for felting. Felting batts from alpaca and wool are an easy way to start.
