What is artificial cotton?
Rayon is the common name for viscose fiber. Viscose fiber refers to α-cellulose extracted from cellulose raw materials such as wood and plant ligustrum, or cotton linters as raw materials, processed into spinning dope, and then wet-spinned to make artificial fibers.
Features of rayon
Artificial cotton is characterized by good dyeability, high brightness and fastness, comfortable wearing, resistance to dilute alkali, and moisture absorption similar to cotton. The disadvantages are acid resistance, poor resilience and fatigue resistance, and low wet mechanical strength. It can be spun purely or blended with chemical fibers such as polyester.
What is pure cotton?
Pure cotton fabric is a textile made of cotton as raw material, through the loom, the warp and weft yarns are interwoven vertically and horizontally. At present, according to the actual source of processed cotton, it is divided into virgin cotton fabric and regenerated cotton fabric.
Features of pure cotton
1) Cotton fiber has good moisture absorption
Under normal circumstances, cotton fiber can absorb moisture from the surrounding atmosphere, and its moisture content is 8%-10%, so when the human skin touches it, it feels soft and comfortable. If the humidity of the cotton fiber increases and the surrounding temperature is high, all the moisture in the cotton fiber will evaporate. Keep the cotton fabric level, and also make people feel comfortable.
2) Pure cotton fabric has good heat resistance
At the same time, when the temperature is below 110 degrees Celsius, it will only cause the moisture on the fabric to evaporate, and will not damage the fiber. Therefore, the cotton fiber is used at room temperature and used at room temperature, and washing will not affect the fabric. In this regard, its heat resistance also improves the durability and washability of cotton fabrics.
3) Cotton fiber has strong resistance to alkali
In the alkaline solution, the cotton fiber will not be damaged, which reflects the alkali resistance of the cotton fiber. Therefore, it is conducive to the washing of pollution and disinfection of impurities after use.
4) Cotton fiber also reflects hygiene
Cotton fiber is a natural fiber, its main component is natural element and a small amount of waxy substances and nitrogenous substances, pectin, after testing and practice, cotton fiber contact with the skin without any irritation and side effects, long-term use is beneficial and harmless to the human body , Its sanitary performance is good.
