1. The differences and characteristics of artificial cotton and pure cotton
1 .Rayon is the common name for viscose fiber.
Viscose fiber refers to wood and plant stems, etc. α-cellulose extracted from cellulose raw materials, or artificial fibers made from cotton linters, processed 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.
CurrentlyAccording to the actual source of processed cotton, it is divided into native cotton fabrics and recycled cotton fabrics.
2. Difference method
p>
rayon cotton The appearance is very similar to cotton cloth, and the difference is mainly based on the following points:
1. Finish
Man-made cotton cloth, smooth 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 there are few yarn defects; while the yarn count of pure cotton cloth is not as uniform as that of artificial cotton, especially in medium and coarse cloth.
3. Feel
Man-made cotton fabrics, whether thick or thin, are mostly soft to the touch, while cotton has a slightly rough feel. p>
4. Color
Artificial cotton has good luster and color. Compared with cotton, artificial cotton is more vivid Beautiful.
5. Wrinkling
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 lighter than artificial cotton.
6. Drapeability
Artificial cotton has better drape, while cotton drape is not as good as artificial cotton.
7. Powerful
The strength of artificial cotton is lower than that of cotton. Especially in humid environment, the fastness of artificial cotton is poor. When compared with drawing from the edge of the cloth and stretching, artificial cotton is easier to break than cotton. Therefore, artificial cotton is easier to break than cotton. Most cotton textures are thicker and not as light and thin as pure cotton and linen yarn.
8. Burning
When artificial cotton is close to the flame, it burns quickly, just like when we burn plastic, black smoke and curls melt. The lower the cotton content, the stronger the gelatinous texture; when cotton is close to the flame, it does not shrink or melt. When exposed to the flame, it burns quickly. The flame is orange with blue smoke
Leave the flame and continue burning. The burning paper will smell less and the ash will be linear. The ash is soft and light gray, and it easily turns into powder when touched. p>
3. 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 it is in cotton The humidity of the fiber increases, and when the ambient temperature is high, all the moisture in the cotton fiber will evaporate, keeping the cotton fabric in a horizontal state, which also makes people feel comfortable. max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;”>
2. Heat resistance of pure cotton fabric Good
At the same time, when the temperature is below 220 degrees Celsius, it 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 alkali solution, cotton fiber will not be damaged, which reflects the alkali resistance of cotton fiber. Therefore, it facilitates washing and disinfecting impurities after use.
4. Cotton fiber also reflects hygiene
Cotton fiber is a natural fiber. Its main components 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. It can be used for a long time. It is beneficial to the human body and has good hygienic performance.
B. Features of artificial cotton
Artificial cotton is characterized by good dyeability, high brightness and fastness, comfortable wearing, resistance to dilute alkali, and hygroscopicity close to cotton. The disadvantages are that it is not resistant to acid, has poor resilience and fatigue resistance, and has low wet mechanical strength. It can be spun purely or blended with polyester and other chemical fibers.
