1st - What is cotton?

When did cotton appear?

The relation between us humans and cotton indeed goes back over 7000 years.
Cotton from 5000B.C. has been excavated from the Tehuacan valley in Mexico, and scraps of cotton fabric have been excavated from the historic remains of the Moenjo-Daro which once flourished around 3000 B.C. in the downstream regions of the Indus river in Pakistan.
What is more, even a mummy that was wrapped in cotton cloth was discovered from an ancient tomb before the Inca Empire.
Like so, all around the world and since long ago cotton has been a part of our lives in numerous ways.
Again, as long as humans continue to plow land to cultivate cotton, it promises us harvests once every year without fail.
The white and soft cotton, it is one of the greatest invaluable gifts that nature gave us.

How is cotton made?

Cotton which is the most used out of all natural materials, is made from the cotton plant.
There is a variety of cotton depending on the kind and production area.
It is similar to the different types of rice such as koshihikari or akitakomachi.

Depending on the region where it is harvested, the fiber's length and strength differ. There are fibers that are around 1cm and there are others that are 6 cm, and each is used in various ways.
When used for clothing, these fibers are spun into thread to make socks and shirts with a weaving or knitting machine.

Even socks and shirts, there are all kinds such as ones that feel soft and ones that feel stiff.
The more you use thread that is spun from long fiber, the softer the touch, and the more it becomes wrinkle resistant. As for socks, Xinjiang cotton cultivated in the Xinjiang Uighur province of China has received attention for its luster, softness, and strength.

The strength of cotton found in the chikuwa (Japanese fish sausage)!?

Cotton is similar to the chikuwa in that the center is hollow and since there is a natural twist, it produces a moderate stiffness and elasticity. Since it is a hollow fiber, it absorbs moisture well and it also has a heat-retaining property because of the air in the concave. The reason why it puffs up when airing it out under the sun, is because the air inside the concaves expand.
Again, since it has a nice touch, it is well used in various items besides socks, such as in underwear, towels, and bedding.
