Silk
Chinese discovered the life cycle of the silkworm more than 4,000 years ago, being the first to make
silk fabrics, according to The Silk Association of Great Britain. In the 10th century, Spain was the
biggest producer of silk in Europe. Technology developed in 1804, in France, allowed the production
of patterned silks. With the creation of cheaper synthetic fibers during the 20th century, the natural-silk
industry started to decline. However, China is still the major producer of raw silk, with more than 50
percent of the world's output.
Leather
Leather was probably the first material used by the primitive people to keep warm and protect the
body. While in the past any hide could become a piece of clothing, the most-used today are cowhide
and sheepskin, according to Higgs Leathers. Use of endangered animals' hides is strictly prohibited by
the international agreement known as CITES, the Convention on International Trade in Endangered
Species of Wild Fauna and Flora.
Wool
Merino sheep have long, soft wool, which was first used in the production of clothes in Spain,
according to the website Wool Lovers. However, the earliest piece of woollen cloth, manufactured
3,500 years ago, was found in Denmark. Nowadays, Merino, Corriedale and other breeds of sheep are
keep for wool production, but the animals' hides are also an important material to produce jackets and
coats.

Chapter 5 - Market segments - Types of cotton
The cotton plant is a perennial tree that has been domesticated to be cultivated as an annual crop. Cotton is a
warm climate crop and is mainly grown between 37°N and 32°S. The northern hemisphere accounts for about
90% of global cotton production. The time of planting in the northern hemisphere is the time of harvesting in the
southern hemisphere.
There are many different varieties and types of cottons. Their characteristics determine the use for the cotton,
and hence its value. Cotton is a member of the order Malvales, family Malvaceae, genus Gossypium. The genus
Gossypium consists of 50 wild and cultivated species, out of which only four are grown on a commercial scale
in the world. Gossypium hirsutum.and G. barbadense are called New World species and account for about 95%
and 3% of world production respectively. G. arboreum and G. herbaceum are called Old World or Asiatic
cottons and are grown commercially in India, Pakistan and parts of South-east Asia, accounting for about 2% of
world production
