ALPACA

The alpaca, whose scientific name is lama pacos, is the most numerous of the four South American camelid species (Llama, Alpaca, guanaco and the vicuña). With a population of 3,5 to 4.0 million in Perú, representing 75% of the world's total, the alpaca provides the main means of sustenance for thousands of families in the high Andes. The Alpaca is one of two domesticated breeds of South American camel-like ungulates: Alpaca and Llama.

The alpaca is usually 1,20m to 1,50m in height, and weighs between 45kg and 79kg. It has a smaller and more curved profile than the llama and has a distinguishing fringe of hair on its forehead.

Up at elevations of more than 4000m above sea level among impressive landscapes where daily temperature ranges can be as much as 30 Celsius degrees, thousands of rural families raise flocks of alpacas, as has been done for thousands of years, shearing the animals and selling their fiber every year, to provide those families with their principal income.

There are two varieties of the alpaca: the Huacayo and the Suri. The Huacayo is the more numerous type in Perú, representing 93% of the population, and has relatively short fiber which is dense, curly and voluminous. The hair covers almost all the body, only the face and lower parts of the legs having a covering of short fibers. The Suri has long, straight hair which is silky and exceptionally lustrous.

Alpacas are shorn with knives or shears, usually once a year between November and April. The yield per animal is very variable, but a general average is about five pounds (2,3kg). There are specimens, however, which can yield fleeces weighing up to 15 pounds (6,9kg).

The color of the fiber is variable, up to 22 colors having been defined, but is more uniform than that of the llama. Alpaca colors range from white to black through grays, fawns and browns. This characteristic is not to be found among other natural fibers, the 'noble' fibers, used in textile production.

The fiber is classified manually according to its fineness and sorted into qualities such as Royal Alpaca (less than 19 microns), Baby Alpaca (22,5 microns), Super Fine Alpaca (25,5 microns), Huarizo (29 microns), Coarse (32 microns) and Mixed Pieces (short fibers generally coarser than 32 microns).

The names of these qualities do not necessarily reflect the age of the animals or other phenotypic characteristics. The appellation 'Baby', for example, is applied to products (tops, yarns, cloth, etc.) where the average fiber diameter is 22,5 microns. The fiber used to obtain this quality does not necessarily come from baby animals; it could easily come from an adult animal with a very fine coat.

Each quality is employed to create different products such as cloth, scarves, sweaters, blankets, carpets and so on. The alpaca may also be blended with other fibers, generally of natural origin.

Alpaca fibers are extraordinarily tough and strong, even in the finest qualities, thus making it ideal for industrial processing. It is furthermore easily dyed to any color and always retains its natural luster.

It is also possible to process alpaca on the woolen or worsted systems, so that it can be used to produce a range of cloths from coarse tweeds to fine gabardine. Alpaca fiber does not easily break, fray, stain or accumulate charges of static electricity; it is easy to launder.

Alpaca provides a relatively high yield of fiber after processing (between 87% and 95% compared with 43% to 76% for sheep's wool). Furthermore, it is easy and economical to process owing to the lack of grease or lanolin in the fiber and, unlike cashmere, does not need to be de-haired.

Some of the factors which affect the value of alpaca are as follow:

• Fineness: This is a genetic hereditary factor. The finer the fiber, the higher the price.

• Color: White fiber commands a higher price from industrial concerns as it may be dyed to any color, including pastel shades. However, craftsmen give a greater value to fiber of certain natural colors.

• Fiber length: The decision of whether to process the alpaca on the woolen system or the worsted system depends on the fiber length.

• Production: The weight and degree of cleanliness of the fleeces are important.

• Impurities in the fiber: Greater prices are commanded by cleaner fiber.

• Nutritional considerations: Nutrition of the animal affects growth and fineness of the fiber.

The following are some of the textile properties of alpaca:

• Non-flammability: The fiber will not burn unless in direct contact with a flame.

• Elasticity and strength: Alpaca fibers have relatively high elasticity and strength, comparable with those of sheep's wool and other animal fibers.

• Hygroscopic properties: Absorption of ambient humidity is relatively low.

• Thermal properties:The structure of the alpaca fiber makes it an efficient thermal insulator, useful in different climatic conditions.

• Felting: Alpaca does not felt as readily as sheep's wool or other animal fibers.

• Handle: The alpaca fiber has a structure which gives it a very soft handle, comparable with that of a grade of sheep's wool three or four microns finer.

• Visual texture: Especially for overcoats, alpaca cloth exhibits an excellent drape, appearance, natural luster and handle; it maintains its new appearance for a very long time.

VICUÑA 

We manufacture limited vicuña knitted garments too, since the low fibre stocks. Please, ask for our vicuña models. The vicuña, whose scientific name is Vicugna vicugna, is a small, graceful animal with a long neck and is the smaller, rarer and more delicate of the South American camelids. It inhabits the higher regions of the Andes at altitudes close to 3800m above sea level.

It may measure from 1,25m to 1,50m to the top of its head, and its hair, which consists of fibers between 2cm and 4cm long, is usually a light brown shade (cinnamon color) on the animal's back and whitish on the chest, belly and the inner parts of the legs. The fibers on the chest may reach a length of 20cm and serve as protection against the cold.

The vicuña may weigh between 35kg and 50kg and can live for up to 20 years. The females give birth to a single young animal - between December and April, but especially in February - after a gestation period of 11 months.

The vicuña lives in three types of groups:

• Family groups consisting of one male, five or six females, and the babies.

• Young males of reproductive age which gather to form groups of up to 200; these animals cooperate with one another and are in a constant state of conflict with the family males for their territory and females.

• Solitary animals, generally family males whose territory and family have been expropriated.

After eight or nine months, the young are expelled form the family group so that inbreeding is avoided. If they are females, they become part of another family group; if they are males, they associate with other males and, from the age of three years, challenge the family males with a view to capturing their females and territory.

The vicuña feeds on the grasses to be found in the puna, which are hard and contain silica, so there is rapid attrition of the animal's incisor teeth. To compensate for this, the incisors grow continuously until the animal reaches about five years of age; after that time, those teeth become worn down to the point that the animal is no longer able to graze and it wastes away and dies.

The hair of the vicuña, with fiber diameters of 10 to 12 microns, is the finest and most sought after in the world. During the Inca Empire, its use was permitted only for making garments to be worn by members of the government. Nowadays, owing to its softness, luster and extreme fineness, this fiber has an extraordinary value in textiles.

During a two-year period, the vicuña produces approximately 200g of fiber which, apart from its fineness, is remarkable for its providing a very high degree of thermal insulation.

During the 1960s, the vicuña was in danger of becoming extinct. Thus in 1975, the Convention on International Trade in Endangered Species (CITES) added the vicuña to the list of internationally protected species, immediately making it illegal to trade in any product derived from this animal. Almost 20 years later, CITES granted permission for the use of vicuña fiber, but in restricted quantities and with certification regarding the way in which the fiber has been obtained.

The vicuñas have to be caught alive so they can be shorn, and then set free in their habitat. It has been possible to achieve this by employing an ancient Inca traditional practice known as Chaccu, where people are deployed in a large circle to surround the vicuñas; the circle is tightened and the vicuñas are driven into corrals where they are shorn and then marked.

The Chaccu festival takes place between November and May, retaining many of its original characteristics, with the exception of sacrificing the animal. Before the Chaccu commences, an advance payment is made to the Pachamama, Mother Earth, giving thanks for the fleeces. The Chaccu starts when the community surrounds the animals and, alarming them, drives them across the plain down a kind of corridor toward the corral.

The current vicuña population in Perú comprises some 140 000 specimens, to be found mainly on the state-protected Nature Reserves in central and southern Perú. This figure represents 85% of the world's population of vicuñas.
