Cotton is also called pure cotton. What are the differences between cotton and polyester/cotton? Cotton fabrics are made of cotton as raw materials, which are woven by weaving machines, which are interwoven with warp and weft yarns. Generally there are labels written [cotton] /Cotton/C.

Let me talk about the characteristics of cotton:
1. Hygroscopicity: Cotton fiber has good hygroscopicity. Under normal conditions, the fiber can absorb water into the surrounding atmosphere, and its moisture content is 8-10%, so it contacts human skin and makes people feel soft. Not stiff.
2. Moisturizing property: Since cotton fiber is a poor conductor of heat and electricity, the heat transfer coefficient is extremely low, and because the cotton fiber itself has porosity and high elasticity, a large amount of air can be accumulated between the fibers, and the air is poor in heat and electricity. conductor.
3. Heat resistance: The cotton fabric has good heat resistance. When it is below 110 °C, it will only cause the water on the fabric to evaporate without damaging the fiber.
Polyester/cotton refers to the general name of blended fabric of polyester and cotton. It is made of 65%-67% polyester and 33%-35% cotton blended yarn, commonly known as polyester cotton.
Polyester cotton features:
It not only highlights the style of polyester but also the strength of cotton fabric. It has good elasticity and wear resistance in dry and wet conditions, stable size, small shrinkage, and is characterized by straightness, not easy to wrinkle, easy to wash and quick-dry. Do not use high temperature ironing and boiling water to soak.
Disadvantages of polyester/cotton: Polyester cotton is a hydrophobic fiber. It has strong affinity for oil stains and is easy to absorb oil. It is easy to generate static electricity during the wearing process, it is difficult to wash, and it cannot be washed with high temperature ironing and boiling water. . Polyester cotton is a synthetic fiber that does not degrade.
Classification of polyester cotton:
Customers who often buy shirts know that many shirts are made of polyester or cotton. "Polyester cotton" and "cotton polyester", the order of the two words has become two different fabrics. "Polyester-cotton" fabric means that the composition of polyester accounts for more than 60%, and the composition of cotton is less than 40%; "cotton polyester" is the opposite, which means that the composition of cotton is above 60%, and the composition of polyester is below 40%.
4. Alkali resistance: cotton fiber has greater resistance to alkali. The cotton fiber does not break in the alkali solution. This property is beneficial to the washing and disinfection of impurities after taking it.
5. Hygiene: Cotton fiber is a natural fiber, its main component is cellulose, and a small amount of waxy substance and nitrogen and pectin.
