Rayon is actually viscose.
At present, there are two names for viscose in the market, one is rayon and the other is rayon. Glue has two English words, one is rayon and the other is viscose.
Some people associate these two English words, thinking that Rayon is called Rayon and Rayon is called viscose, but this title is debatable. Others think that both English words can be expressed as long as they are viscose. Rayon and rayon are actually two kinds of viscose with different lengths. Generally, viscose is called rayon if it is cut into short fibers. Why do you call it that? One is that cotton fiber is also short fiber, and because viscose has good hygroscopicity, even better than cotton fiber, the common name of viscose short fiber is called "rayon".
Rayon is a kind of long viscose fiber, and the woven fabric is smooth and delicate. Moisture absorption and breathability, if the fabric is thin, it can also be made into silk-like effect, which is better than chemical fiber, because chemical fiber does not absorb moisture, but only improves the luster similar to silk.
What is rayon and what are the characteristics of rayon fabrics?
Man-made cotton is a kind of cellulose fiber synthesized by processing cellulose fiber, also called man-made cotton, and viscose fiber is the most common. Compared with ordinary cotton, artificial cotton fiber is cleaner, has higher crystallinity, can have a certain length as required, and has good spinnability.
Viscose fiber belongs to regenerated cellulose fiber. It is made of natural cellulose through alkalization, aging, yellowing and other processes, then dissolved in dilute alkali solution to make viscose, and then wet spinning. Ordinary viscose fiber, high wet modulus viscose fiber and high strength viscose fiber can be obtained respectively by using different raw materials and spinning processes.
Ordinary viscose fibers have general physical and mechanical properties and chemical properties, which are divided into cotton type, wool type and filament type, commonly known as rayon, rayon and rayon. High wet modulus viscose fiber has high polymerization degree, strength and wet modulus. This kind of fiber can bear the load of 22.0 cn/tex in wet state, and the wet elongation under this load is not more than 15%, which is mainly rich and powerful fiber. High strength viscose fiber has high strength and fatigue resistance.
The basic component of viscose fiber is cellulose.
The cross section of ordinary viscose fiber is zigzag sheath-core structure, which is straight in the longitudinal direction and grooved in the transverse direction. However, the fiber-rich coreless structure has a circular cross-section.
The breaking strength of ordinary viscose fiber is smaller than that of cotton, which is about 1.6 ~ 2.7 CN/dtex. The elongation at break is higher than that of cotton 16% ~ 22%. The wet strength decreased a lot, about 50% of the dry strength, and the wet elongation increased about 50%. Its modulus is lower than that of cotton, and it is easy to deform under small load, but its elastic recovery performance is poor, so the fabric is easy to stretch and its dimensional stability is poor. The strength, especially wet strength, of rich fiber is higher than that of ordinary viscose, and the elongation at break is smaller and the dimensional stability is better. The wear resistance of ordinary viscose is poor, while the fiber-rich viscose is improved.
Viscose fiber has good hygroscopicity, and the moisture regain is about 13% under general atmospheric conditions. After moisture absorption, the fabric expands obviously, and the diameter can be increased by 50%, so the fabric feels hard when it meets water, and the shrinkage rate is large.
The chemical composition of viscose fiber is similar to cotton, so its alkali resistance is stronger than acid resistance, but its alkali resistance and acid resistance are worse than cotton. Rich fiber has good alkali resistance and acid resistance.
Similarly, the dyeing performance of viscose fiber is similar to that of cotton, with complete dyeing spectrum and good dyeing performance. In addition, the thermal properties of viscose fiber are similar to cotton, and the density is close to cotton, ranging from 1.50 to 1.52 g/cm3.
Viscose fiber is one of the earliest chemical fibers put into industrial production. Because of its good hygroscopicity, comfortable wearing and excellent spinnability, it is often blended with cotton, wool or various synthetic fibers and used in various garments and decorative textiles. High strength viscose fiber can also be used in tire cord, conveyor belt and other industrial products.
Viscose fiber is a widely used chemical fiber.
What fabric is rayon? The difference between rayon and pure cotton.
Cotton staple fiber spun from natural cellulose. Mainly viscose staple fiber. It is characterized by good dyeability, high brightness and fastness, comfortable wearing, dilute alkali resistance and hygroscopicity close to cotton. Disadvantages are poor acid resistance, resilience and fatigue resistance and low wet mechanical strength. It can be spun pure or blended with polyester and other chemical fibers.
The appearance of artificial cotton is very similar to that of cotton cloth, and the differences are mainly carried out from the following points:
1. smoothness: man-made cotton cloth, with smooth surface, few yarn defects, no impurities, fine and smooth; Cotton shell and impurities can be seen on the surface of cotton cloth, and its smoothness is not as good as that of artificial cotton cloth.
2. Evenness: rayon cloth is even and has few yarn defects; However, the uniformity of pure cotton yarn is not as uniform as rayon, especially for medium and coarse fabrics.
3. Feel: Man-made cotton cloth, regardless of thickness, feels soft, and cotton cloth is slightly rough.
4. Color: Man-made cotton cloth has good luster and color. Compared with cotton cloth, man-made cotton cloth is brighter.
5. Wrinkling: Man-made cotton cloth wrinkles easily. When a cloth is scattered by hand, many folds appear, which is not easy to recover in time; Although cotton cloth has wrinkles, it is slightly lighter than rayon.
6. Drapability: Rayon has better drapability, while cotton has worse drapability than Rayon.
7. Strength: The strength of man-made cotton cloth is lower than that of cotton cloth. Especially in humid environment, the fastness of artificial cotton is poor, and it is easier to break than cotton silk when it is pulled out from the edge of cloth. Therefore, most artificial cotton is thicker than pure cotton linen.
What fabric is blue crystal rayon?
It is artificial cotton produced by Blue Whale Company, also called viscose fiber.
Lanjing is a brand of Lanjing Group of Lanjing Fiber (Shanghai) Co., Ltd..
Blue Whale Group is an international group headquartered in Austria, with production bases in major markets and a global marketing and promotion network. Blue Whale Group provides high-quality cellulose fibers to the global textile and nonwoven fields, and is an important supplier in many commercial fields-from cellulose fibers to special plastic products.
Blue Crystal's quality management and innovative ability set an industry standard for the man-made cellulose fiber industry. More than 70 years of fiber production experience makes Blue Whale Group the only fiber producer in the world that can produce three generations of cellulose fibers, including traditional viscose fiber, modal fiber and lyocell fiber. Paying unremitting attention to customer needs, while maintaining the leading position in quality, innovation and technology, the organic combination of the two is the foundation of the success of Blue Whale Group.
Blue Whale Fiber (Shanghai) Co., Ltd. is a wholly-owned subsidiary of Austrian Blue Whale Company, which is responsible for the textile fibers produced by Blue Whale Group, including Tencel? , Lanjing Modal? , blue crystal viscose? And blue crystal for heat protection? Application, development and promotion services of fiber in China market.
20 1 1 In August, Austrian fiber manufacturer Lanjing held the inauguration ceremony of a new production line in China. This will increase the output of viscose fiber140,000 tons. The production line is located in Blue Whale Nanjing Fiber Factory, so the factory capacity can be doubled, and the output is mainly supplied to the Asian market.
