Textile Innovation: Presentation 1

This course introduced a lots of differences of materials of feathures and what kind of fabrics can use in different purpose. There are main purpose for textile : transportatio,argriculture, geo textil, medical, architecture, active sports, domestic, interiors, commercial fibre sources. In the other hand, I started to know there are some main materail in textile as weel, for exmaple, cotton, lilen, silk, wool, luxury hair fibres, man made cellulosics, acrylic,polyamide, polyester and stretch fibres.

I'm especially interested in wool in Peru and Chile.
There are some incredible animals with their beautiful wool:
llama, alpaca, vicuña and guanaco.
Basically , they are all live in high altitude places.
The adverge price for these wool :
llama：$ 5 USD per kg
alpaca：$ 50 USD per kg
vicuña：$ 1000 USD per kg
But, the prices normally should depend on breeding history, sex, and color.
guanaco price is between vicuña and alpaca.
Alpaca and Ilama both exist only as domesticated animals.
//1// llama (Lama glama)
Compared to Alpace, llama hair is shorter. So, this animal don't provide good quality of wool. The wool of they come in many different colors ranging from white or grey to reddish-brown, brown, dark brown and black.

//2// alpaca (Vicugna pacos)
1) pretty unbreakable fabrics

2) It is really healthy and comfortable to wear
.The absence of lanolin and other oils in the fleece and its extraordinary fineness of handle mean that alpaca garments are both hypoallergenic and luxuriously soft on your skin.
3)alpacas produce fleece in more than 22 different colors.

4) Alpaca fiber can easily recycle.

5) The improvement of diet , high-quality veterinary care, and scientific selective breeding will make better quality of alpaca wool in the future.

*There are two type of alpaca : Huacaya and Suri

Suri, , prized for their longer and silkier fibers.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 they were developed in South America.

Suri

Huacaya, produce a dense, soft, crimpy sheep-like fiber.

Huacaya

I'm especially interested in wool in Peru and Chile.

Basically , they are all live in high altitude places.
The adverge price for these wool :

vicuña：$ 1000 USD per kg
guanaco's price is between vicuña and alpaca.

But, the prices normally should depend on breeding history, sex, and color.

Vicuña and Guanaco live in wild.

//1//vicuña (Vicugna)
They apparently have tall and skinny body and the wool of they is popular due to its warmth and it is also the finest and the most expensive wool in the world. A single vicuña produces a pound of wool every year which, under Peru’s labeling system, can only be harvested every three years.

//2//guanaco(or huanaco) (Lama guanicoe)
They have obvious black face.
Guanaco fiber is particularly soft, warm feel and is found in luxury fabric. The guanaco's soft wool is valued second only to that of the vicuña. The pelts, particularly from the calves, are sometimes used as a substitute for red fox pelts, because the texture is difficult to differentiate. Like their domestic descendant, the llama, the guanaco is double coated with a coarse guard hair and soft undercoat, which is about 16-18 µ in diameter and comparable to the best cashmere.

Color varies with region
- Light brown, brownish yellow, or brownish red on back and neck
- White belly, rump and backs of legs
- Head, ears, and nape of neck are gray
