Cotton can be made into crochet or wool for knitting. Fibers can also be collected from cotton or knitted fabrics that are not needed in weaving, knitting or cutting. Many materials are made entirely of cotton, but some materials will mix cotton with other fibers (such as rayon or polyester).

Cotton history
Cotton planting first appeared in indus valley civilization in 5-4 thousand BC, and before 1 year, the use of cotton textiles spread to the Mediterranean region. In the first century, Arab merchants brought exquisite tulle to Italy and Spain. Around the 9th century, the Moors introduced the cotton planting method to Spain.
Medieval cotton is an important imported material in northern Europe. People there have obtained wool from sheep since ancient times, so when they heard that cotton was planted, they thought it came from a special kind of sheep, which grew from trees, so the word cotton was translated directly into "tree hair" in German.
/kloc-In the 6th century, the Spanish entered southern Mexico and Yucatan Peninsula, and found that the local cotton planting industry was very developed and the cotton quality was better. The islanders spun colored cotton into homespun and made them into local clothes. At present, more than 90% of the world's total cotton production is upland cotton originating in Mexico.
However, until modern times, cotton yarn was not as widely used as wool and flax. This is because flax or wool fibers are longer than cotton fibers and are easier to spin into yarns. In addition, cotton fibers can only be separated from seeds manually, which is very tedious and time-consuming. ?
With the invention and use of serrated cotton gin for the first time in modern North Carolina and Virginia, the extraction and separation of cotton staple fibers become simple and fast.
With the rapid improvement of production efficiency and the low labor cost in the southern United States, the share of cotton yarn in the global textile market has increased rapidly. With the continuous improvement of mechanization and the production of fiber and yarn, cotton products have become low-priced commodities. Cotton planting needs a warm climate and a high level of water or irrigation.
Today, cotton is the most widely used fiber in the world. Its popularity stems from its easy production and wide applicability in the field of textile products. The price of cotton yarn strongly depends on the labor cost, so in developed countries, the price of cotton yarn is relatively high because of the expensive labor.
