The differences and characteristics of artificial cotton and pure cotton
1. Rayon is the common name for viscose fiber.
Viscose fiber refers to α-cellulose extracted from cellulose raw materials such as wood and plant stalks, or processed from cotton linters. Man-made fibers are made into spinning solution and then wet-spun.
2. Pure cotton fabric is a textile made of cotton as raw material and made of warp and weft yarns intertwined vertically and horizontally through a loom.
Currently, according to the actual source of processed cotton, it is divided into native cotton fabrics and recycled cotton fabrics.
How to distinguish
The appearance of man-made cotton cloth is very similar to cotton cloth. The main differences are as follows: Several points:
1. Smoothness
Man-made cotton cloth, smooth cloth surface, yarn defects Very few, no impurities, 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 cloth is even and the yarn count is even. There are very few defects; while the yarn count of pure cotton is not as uniform as that of artificial cotton, especially in medium-coarse cloth.
3. Feel
Man-made cotton fabrics, whether thick or thin, are mostly soft to the touch, while cotton fabrics It feels slightly rough.
4. Color
Man-made cotton cloth has good luster and color, compared with cotton cloth , artificial cotton is more colorful and beautiful.
5. Wrinkling properties
Man-made cotton cloth wrinkles easily. When holding 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. Drapability
Artificial cotton has better drape, while cotton has better drape than artificial cotton.
7.Strength
The strength of artificial cotton is lower and not as good as cotton, 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. Burn
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 burning paper will produce less odor and ash, which will appear linear. The ash is soft, light gray, and easily turns into powder when touched.
Characteristics of pure cotton and artificial cotton
A. Characteristics of pure cotton
1. Cotton fiber has good hygroscopicity
Under normal circumstances, cotton fiber can absorb moisture from the surrounding atmosphere, and its moisture content is 8%—10%, so when the human skin comes into contact, 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. Keeping cotton fabrics horizontal also makes people feel comfortable.
2. Pure cotton fabric has good heat resistance
At the same time, when the temperature is below 110 degrees Celsius , will only cause the water on the fabric to evaporate and will not damage the fiber. Therefore, 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 an alkali solution, Cotton fiber will not be damaged, which 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. The main ingredients are natural pigments and a small amount of waxy substances, nitrogen-containing substances and pectin. After testing and practice, cotton fiber has no irritation or side effects when it comes into contact with the skin. Long-term use is beneficial to the human body and has good hygienic properties.
B. Characteristics of artificial cotton
The characteristics of artificial cotton are It has good dyeability, high brightness and fastness, comfortable wearing, resistance 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.
