The most widespread and inexpensive plant fiber in the world to manufacture is cotton. The plant began to be cultivated several thousand years ago in America; later, cotton began to be grown in China and India. On the territory of the former USSR, cotton fields were concentrated in Uzbekistan. The fabric is made from fibers (cotton wool) that are formed inside the cotton seed boll. Depending on the length and thickness of the fiber, the yarn is short-staple, fine-staple and medium-staple. Cotton fiber is 95% cellulose, the rest is an admixture of minerals and fats. Natural cotton fabric has the following positive qualities:
The disadvantages include: poor resistance to decay, loss of strength when exposed to high temperatures and fragility in wear. Eliminate these disadvantages by adding synthetic threads in the manufacture of fabric. Nowadays, all-natural cotton fabric is not as common as it used to be. The addition of synthetics multiplies the wear resistance and appearance (it is less wrinkled) of the fabric. Note: if you set fire to a piece of natural cotton, it will burn without residue, exuding the smell of burning paper. Cotton fabrics:
To give additional strength, a nylon thread is woven into the cotton fabric. Such material is used for sewing workwear. In addition to nylon, artificial fibers are added to cotton threads: viscose, polyester, acetate.

Due to its hygroscopicity and softness, the cotton fabric is comfortable and pleasant for the body. It does not cause allergies and prickly heat in children. Chintz, cambric, marquise, calico, calico, flannel are used for sewing. In order for a thing made of natural fabric to serve for a long time and retain its appearance, you must adhere to simple rules.
