The concept and characteristics of artificial cotton
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 stalks, or man-made fiber made from cotton linters, processed into spinning solution, and then wet-spun.
Characteristics of artificial cotton
The characteristics of artificial cotton are 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.
The concept and characteristics of pure cotton
What is pure cotton?
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.
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 it is below 110 degrees Celsius, it will only cause the water on the fabric to evaporate and will not damage the fiber, so the cotton fiber will not be damaged at room temperature. It can be used at room temperature and will not have any effect on the fabric during washing. Its heat resistance also improves the durability and washability of cotton fabrics.
3) Cotton fiber has strong resistance to alkali
In 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 hygienic properties
Cotton fiber is a natural fiber, and its main components are natural pigments and a small amount of waxy substances and nitrogenous substances, pectin, After testing and practice, cotton fiber has no irritation or side effects when it comes into contact with the skin. It is beneficial and harmless to the human body after long-term use, and its hygienic performance is good.
The difference between artificial cotton and pure cotton
The appearance of artificial cotton cloth is very similar to cotton cloth. The difference is mainly based on the following points:
Man-made cotton cloth has a smooth surface with very few yarn defects, no impurities, and is clean and smooth; while cotton shells, impurities, etc. can be seen on the surface of cotton cloth, and its smoothness is not as good as that of artificial cotton cloth.
Thread count evenness
The yarn count of artificial cotton cloth is even and there are few yarn defects; while the yarn count of pure cotton cloth is not as uniform as that of artificial cotton, especially the medium and coarse cloth. To be obvious.
Regardless of the thickness of the fabric, artificial cotton fabrics mostly have a soft hand feel, while cotton fabrics have a slightly rough feel.
Man-made cotton cloth has good luster and color. Compared with cotton cloth, artificial cotton cloth is more bright and beautiful.
Man-made cotton cloth wrinkles easily. When you hold a handful of cloth with your hands and spread it, many wrinkles will appear and it is not easy to recover in time. Although cotton cloth has wrinkles, it is more wrinkled than artificial cotton cloth. Lightly cotton.
Artificial cotton has better drape, while cotton has less drape than artificial cotton.
The strength of artificial cotton is lower than that of cotton. Especially in humid environments, the fastness of artificial cotton is poor. When compared with drawing from the edge of the cloth, stretching will Artificial cotton is easier to break than cotton filaments. Therefore, the texture of artificial cotton is mostly thicker and not as light and thin as pure cotton and linen yarn.
