Washed cotton is not polyester fiber, but a fabric processing technology. Washed cotton is a texture that appears after cotton fabrics have been washed, sanded, etc.
In fact, the main component of cotton fabric is composed of plant fibers, while silk is made of silk secreted by insects. In contrast, polyester fiber is a synthetic fiber that is chemically extracted from petrochemicals such as petroleum and then polymerized.
Polyester fiber is characterized by high strength, wear resistance, good softness, good wrinkle resistance and washing resistance, so it is widely used in Textiles, clothing, home accessories and other fields.
Washed cotton is characterized by soft and comfortable feel, and is not easy to wrinkle. It is very suitable for making bedding, clothing, etc. During the processing process, washed cotton will be washed, sanded, bleached and other treatments many times to make its fibers soft and plush, making it more suitable for close contact with human skin.
In short, washed cotton and polyester fiber are not the same concepts. The former is a fabric processing technology, and the latter is a raw material for synthetic fibers.
