1. Rayon is the common name for viscose fiber.
Viscose fiber refers to fibers such as wood and plant stalks α-cellulose extracted from vegetarian raw materials, or artificial fibers made from cotton linters, processed into spinning solution, and then wet-spun.
2. Pure cotton fabric is made of cotton as raw material. Machine, a textile made of warp and weft yarns intertwined vertically and horizontally.
Currently, according to the actual source of processed cotton, it is divided into virgin cotton fabrics and recycled cotton fabrics.
The appearance of artificial cotton cloth is very similar to cotton cloth. The difference is mainly based on the following points:
1. Finish
Man-made cotton cloth, smooth surface, few yarn defects, no Impurities, fine, clean and smooth; while cotton shells, impurities, etc. can be seen on the surface of cotton cloth, and the smoothness is not as good as artificial cotton cloth.
2. Yarn count uniformity
The yarn count of artificial cotton is uniform and there are few yarn defects ; The yarn count of pure cotton cloth is not as uniform as that of artificial cotton, especially for medium-coarse cloth.
3. Feel
Man-made cotton fabrics, whether thick or thin, are mostly soft to the touch, while cotton It feels slightly rough.
4. Color
Artificial cotton has better luster and color than cotton , artificial cotton cloth is more colorful and beautiful.
5. Wrinkling
Artificial cotton cloth is easy to wrinkle. When you hold a handful of cloth with your hands, If it spreads, there will be many wrinkles and it will not be easy to recover in time. Although cotton cloth has wrinkles, it is lighter than artificial cotton.
6. Drape
Artificial cotton has better drape, while cotton drape is not as good as artificial cotton .
7. Powerful
Man-made cotton cloth has lower strength and is not as good as cotton cloth, especially in In a humid environment, rayon has poor fastness. When drawn from the edge of the cloth and stretched, rayon is easier to break than cotton. Therefore, the texture of rayon is mostly thicker and not as light and thin as pure cotton and linen yarn.
8. Burning
Artificial cotton is close to the flame and burns quickly, just like we burn plastic Black smoke and curly melting also appear. The lower the cotton content, the stronger the gelatinous texture; cotton is close to the flame and does not shrink or melt. When exposed to flame, it burns rapidly with orange flame and blue smoke.
Leave the flame and continue burning. The paper will smell less and have less ash. linear. The ash is soft, light gray, and easily turns into powder when touched.
2. Pure cotton fabric has good heat resistance
At the same time, below 110 degrees Celsius, it will only cause fabric stains The water will evaporate and will not damage the fiber, so cotton fiber can be used at room temperature and washing will not affect the fabric. Its heat resistance also improves the durability and washability of cotton fabrics.
3. Cotton fiber has strong resistance to alkali
In alkaline solution, cotton fiber will not be damaged. Reflects the alkali resistance of cotton fiber. Therefore it facilitates the washing and disinfection of contaminated impurities after use.
4. Cotton fiber also reflects hygiene
Cotton fiber is a natural fiber, and its main ingredients are natural pigments and A small amount of waxy substances and nitrogenous substances, pectin, after testing and practice, cotton fiber and skin contact without any irritation or side effects, long-term use is beneficial to the human body, and its hygienic performance is good.
Artificial cotton is characterized by good dyeability, brightness and fastness High strength, comfortable to wear, resistant to dilute alkali, and hygroscopicity close to cotton. The disadvantages are that it is not acid-resistant, has poor resilience and fatigue resistance, and has low wet mechanical strength. It can be spun purely or blended with chemical fibers such as polyester.
