Wool is the most important natural fiber in the world, it is shorn from sheep or goat and is mainly composed of animal proteins. The properties of wool fiber include good elasticity, low abrasion resistance. It is also very comfortable and attacked by moths. Additionally, wool fiber has been used in clothing manufacturing, such as making suits, dresses, coats, and carpets. Say no to plagiarism.

Although wool is produced in more than 100 countries across the World, over 90% of the wool in the global textile market is produced by the following 11 largest wool producing countries. According to the International Wool Textile Organization, Australia, China, the United States, New Zealand and Argentina are the leading wool-producing countries in the world. Australia is the highest wool producing country in the world, responsible for producing 25% of the world's wool. There are approximately 70 million sheep in Australia, producing an average of 4.6kg of wool per capita and a total fat wool yield of 340 million kilograms. By having a large number of sheep raised, Australian industries can produce a large amount of wool. In recent years, Australia's annual wool production has remained at 330,000 tonnes. China is the second largest wool producer in the world, producing around 160,000 tonnes of wool per year. The United States produced 25.7 million pounds of wool. The fourth largest wool producer in the world is New Zealand, which produces 11% of the world's wool. The fifth largest wool producing country is Argentina, which produces 3% of the world's wool. Comparison between greasy wool and worsted yarn Wool is obtained by shearing the fleece from the backs of sheep once a year, which requires it to undergo a series of processes to transform it into a useful yarn. Furthermore, greasy wool is the raw material of wool, while worsted yarn is in the form of yarn. There are three differences between fat wool and worsted yarn. First, the composition of greasy wool contains some impurities, while worsted yarn is free of impurities. Oily wool is shorn from sheep that have not undergone any process to remove impurities such as wool grease, sweat and dirt from the wool. Therefore, greasy wool may include some ingredients such as sunt, herbal substances and other ointments. On the contrary, after carrying out the general procedures to transform it into yarn, the combed yarn is lighter and purer than greasy wool. Secondly, the other difference between fat wool and worsted weight yarn is the texture. Worsted yarn is formed after the twist enters the straightened and parallel fibers. With less air trapped between the fibers, worsted yarn will tend to be heavy. On the contrary, the greasy wool will not carry out any twisting and this will result in the greasy wool deliberately trapping more air, and therefore being much more elastic and lighter. Furthermore, the fiber length of greasy wool depends on the growth rate which depends on genetic and environmental factors, while the length of combed yarn depends on the spinning process. However, the surface structure of the fiber of greasy wool and worsted yarn is the same. Both are made from wool fibers that contain different lengths from 0-1 millimeter to more than 10 millimeters. Each fiber is covered in overlapping scales, but is not twisted. It is curled or wavy. As well as the structure of fat wool and yarn.
