One, the difference and characteristics of rayon and pure cotton.
1. Artificial cotton 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.
2. Pure cotton fabric is a textile made of cotton as raw material, which is interwoven with warp and weft yarns vertically and horizontally through a loom.
At present, according to the actual source of processed cotton, it is divided into virgin cotton fabric and recycled cotton fabric.
Two, the difference method.
The appearance of rayon cloth is very similar to cotton cloth, and the method of distinguishing it is mainly from the following points:
Artificial cotton cloth has a smooth surface, few yarn defects, no impurities, fine and smooth; while cotton shells and impurities can be seen on the surface of cotton cloth, and the finish is not as good as artificial cotton cloth.
2. Yarn count uniformity
The yarn count of rayon cloth is even, with few yarn defects; while the yarn count of pure cotton cloth is not as uniform as rayon, especially for medium coarse cloth.
The strength of rayon cloth is lower, not as good as cotton cloth, especially in a humid environment, rayon has poor fastness, when drawing from the edge of the cloth, stretch, rayon is easier to break than cotton, therefore, the texture of rayon is mostly better. Thick, not as light as pure cotton yarn.
Third, the characteristics of pure cotton and artificial 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, so 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 washing and disinfecting 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 substance and nitrogenous substance, 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.
