. Alpaca is naturally water-repellent and difficult to ignite. Huacaya, an alpaca that grows soft spongy fiber, has natural crimp, thus making a naturally elastic yarn well-suited for knitting. Suri has far less crimp and thus is a better fit for woven goods. The designer Armani has used Suri alpaca to fashion men's and women's suits.. Alpaca fleece is made into various products, 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," to make the manufacture of alpaca fiber products less expensive.

Types

There are two types of alpaca: Huacaya (which produce a dense, soft, crimpy sheep-like fiber), and the Suri (with silky pencil-like locks, resembling dreadlocks but without matted fibers). Suris, prized for their longer and silkier fibers, are estimated to make up 19-20% of the North American 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, most likely because the breed was reserved for royalty during Incan times. Suris are often said to be less cold hardy than Huacaya, but both breeds are successfully raised in more extreme climates than those in which they were developed in South America.

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 and myths involved the alpaca, perhaps most notably the myth regarding the method of killing the animal: 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.

Due 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.

In recent years, interest in alpaca fiber clothing has surged, perhaps partly because alpaca ranching has a reasonably low impact on the environment. Individual U.S. farms are producing finished alpaca products like hats,mitts, scarves, socks, insoles, footwarmers, sweaters, jackets, as well as almost any other product.

Fiber structure

In physical structure, alpaca fiber is somewhat akin to hair, being very glossy. Alpaca fiber is similar to merino wool fiber, and alpaca yarns tend to be stronger than wool yarns. The heel hole that appears in wool socks or in elbows of wool sweaters is nonexistent in similar alpaca garments. In processing, sliver

A roving is a long and narrow bundle of fibre. It is usually used to spin woollen yarn. A roving can be created by carding the fibre, and it is then drawn into long strips. Because it is carded, the fibres are not parallel, though drawing it into strips may line the fibres up a bit...

s lack strength. Blend these together and the durability is increased several times over. More twisting is necessary, especially in Suri, and this can reduce a yarn's softness.

The alpaca has a very fine and light fleece. It does not retain water, is thermal even when wet and can resist solar radiation effectively. These characteristics guarantee the animals a permanent and appropriate coat to fight against the extreme changes of temperature. This fiber offers the same protection to humans.

Medullation

Medullated fibres are fibres with a central core, which may be continuous, interrupted, or fragmented. Here, the cortical cells that make up the walls of the fibre, are wrapped around a medulla, or core, that is made up of another type of cell (called medullary cells). Later, these
cells may contract or disappear, forming air pockets which assist insulation.

Medullation can be an objectionable trait. Medullated fibers can take less dye, standing out in the finished garment, and are weaker. The proportion of medullated fibers is higher in the coarser, unwanted guard hairs: there is less or no medullation in the finer, lower micrometer fibers... These undesirable fibers are easy to see and give a garment a hairy appearance. Quality alpaca products should be free from these medullated fibers.

, the world wholesale price for processed, spun alpaca “tops” is only between about $10 to $24/kg (according to quality), i.e. about $0.28 to $0.68 per oz.. Finer fleeces, ones with a smaller diameter, are preferred, so are more expensive. As an alpaca gets older, the diameter of the fibers gets thicker, between and per year. This is sometimes caused by overfeeding; as excess nutrients are converted to (thicker) fiber rather than to fat.

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 22 natural colors, with more than 300 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. The demand for darker fiber sprung up in the United States and elsewhere, though, to reintroduce the colors, but 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 over the last few years.

Dyeing

Before dyeing, the alpaca fiber must go through other stages:
  1. Selection of wool, according to color, size and quality of fiber
  2. "Escarminado", removal of grass, dirt, thorns, and other impurities
  3. Washing, to remove all the dirt and grease
  4. Spinning


Once the fiber is clean, it is possible to begin the process of dyeing.

Natural dyeing: (recipe used by Andean artisans):
To dye 1 kg of alpaca wool with cochinilla (natural dye
Natural dye

),
  1. Boil 5 liters of water in an aluminum can with 100 g of cochinilla for an hour.
  2. Sift and put the fiber in the water.
  3. Boil again for an hour and add 50 lemons cut in halves.
  4. Then take out the wool and hang for drying.

Note: For dyeing with another natural dye (native plants), add 2 kg of the products to the water and boil.

Uses

Alpaca fiber is used for many purposes, including making clothing such as hats, mitts, scarves, gloves, and jumpers. It can also be used for rerooting dolls' hair, for example in Blythe dolls. Many breeders are coming up with new ways to use the fibre from their alpacas, from crafting, to wall hangings, to clothing.
