Do viscose and lyocell belong to chemical fibers or natural fibers?

Lyocell fiber, commonly known as "Tencel", uses natural plant fibers as raw materials, came out in the mid-90s of the 20th century, and is known as the most valuable product in the history of man-made fibers in the past half century. Lyocell fiber has a variety of excellent properties of natural fibers and synthetic fibers, lyocell is a green fiber, its raw material is inexhaustible cellulose in nature, there is no chemical reaction in the production process, the solvent used is non-toxic, the waste is biodegradable, the production process is simple, it can save petroleum resources, and meet the requirements of environmental protection, so it has attracted great attention from the polymer materials industry at home and abroad in recent years. In 1997, the Shanghai Municipal Science and Technology Commission commissioned Donghua University to conduct laboratory research, and invested 1 million yuan in the industrialization test when the scientific research funds had been basically allocated that year.

Later, the Shanghai Municipal Science and Technology Commission and the Shanghai Textile Holding Group invested 4.2 million yuan and 6.4 million yuan respectively to increase development efforts. Through the combination of "production, education and research", Donghua University has completed various research tasks in advance, and initially formed the basic software of lyocell textile technology, and the production of lyocell fiber has reached the international advanced level by expert appraisal. "Lyocell" fiber is a new textile and clothing fabric, which emerged in Europe and the United States in the mid-to-late 90s of the 20th century.

It not only has the characteristics of natural fiber cotton, such as comfort, good hand feel and easy dyeing, but also has the environmental protection advantages that traditional viscose fiber does not have. Viscose fiber is made of petroleum, and harmful gases such as carbon disulfide and hydrogen sulfide will be released during the production process, polluting the environment, so it has been gradually eliminated in developed countries. "Lyocell" fiber is made of renewable bamboo, wood and other mashed pulp as raw materials, and the advanced technology makes its solvent rate as high, which is not only energy-saving, environmentally friendly, but also sustainable development.

Clothes made of this fiber not only have a natural luster, smooth feel, high strength, and basically do not shrink, but also have good moisture permeability and air permeability, and the effect of fabrics blended with wool is good. "Lyocell" fiber is the international artificial and synthetic fiber standards bureau for the organic solvent spinning method of cellulose fiber production of the general name, at present only a few countries in the world have mastered the production technology of this new fiber, the global annual production capacity is only 150,000 tons, domestic has not been industrialized production. After 6 years of cooperative research and development between Shanghai Textile Holding Group and Donghua University, it has passed the experimental production of 100 tons of "lyocell" fiber production equipment, and the experimental products have been put on the market and are well received.

Soon, the first domestic industrial production line with an annual output of 2,000 tons of "lyocell" fiber will start construction in Shanghai Textile Holding Group. On this basis, its annual production capacity will be gradually increased to 23,000 tons.

Viscose and lyocell are both chemical fibers.

Viscose is a chemical fiber made from natural plant fibers and chemically treated, also known as rayon. Lyocell is a cellulose fiber made from natural plant fibers through special chemical treatment, also known as lyocell.

Compared to natural fibers, viscose and lyocell are made from a wider range of raw materials** and the production process is more stable, so they are more controllable. At the same time, both fibers have high strength, better moisture absorption, air permeability, and better wrinkle resistance and antistatic properties.

In general, viscose and lyocell are two important chemical fibers, which have a wide range of applications in textiles, clothing, household goods, and other fields.

It is made entirely of natural fiber materials, which are reformed and belong to natural fibers.

Hello, Xiaohai, a home expert, is happy to answer for you. Lyocell fiber, also known as lyocell, is a kind of regenerated cellulose fiber, which is made by processing wood pulp or bamboo pulp. Polyester fibers are chemically synthesized fibers and organic polymers, both of which are man-made fibers, but the raw materials are different.

Advantages of lyocell fiber: 1. The most important advantage of lyocell fiber is its green environmental performance, lyocell fiber is not only a natural plant fiber, but also does not have any chemical reaction in the processing process, so it is beneficial to the environment and health, and can be used with confidence. So we also say that lyocell fiber is a green fiber fabric.

2. Lyocell fiber has the warmth of wool in terms of wearing, no static electricity, and anti-allergic. At the same time, it has the softness of cotton and the high strength of polyester, which is durable. 3. Lyocell fiber has the luxury of woolen fabric and the drape of modal in appearance, and the surface is bright and bright, which is very suitable for making high-end products.

In terms of washing, it resists pilling and has very little shrinkage.

Which is better, lyocell or viscose': Lyocell fiber is better. Viscose fiber is the same as lyocell fiber, but the lyocell process is more advanced, and it is cooler to bend quickly.

1. Viscose fiber has good hygroscopicity, in line with the physiological requirements of the human body, the fabric is soft, smooth, good air permeability, not easy to generate static electricity, anti-ultraviolet, comfortable to wear, easy to dye, bright color after dyeing, good color fastness, and good spinning performance. 2. Lyocell fiber: with a variety of excellent properties of natural fiber and synthetic fiber, natural luster, smooth feel, high strength, basically no shrinkage, and good moisture permeability, air permeability, soft, comfortable, smooth and cool, good drape, limb hall durable and durable.

Hello dear! We'll be happy to answer for you. Is nylon the same as the glued cover rolling fiber and lyocell?

1. Different fiber composition: lyocell is a man-made regenerated cellulose fiber, and viscose and so on are all regenerated cellulose fibers, and the raw materials are plant-based materials, which are different from cotton pulp, wood, etc., but the production process is different. Nylon is a chemically synthesized fiber, which is a polyamide fiber that is chemically synthesized from a material extracted from petroleum products.

2. Different chemical characteristics: lyocell raw materials come from natural wood and can be degraded naturally. It has a silky luster and feel, and its drape is better than cotton, polyester, and rayon.

The strength is higher than that of pure cotton and polyester cotton, and the moisture absorption capacity is 50% higher than that of cotton fiber. Nylon fabric has good abrasion resistance, better moisture absorption than polyester, elasticity and recoverability, and good antibacterial and mildew resistance. Different fiber fabrics, there is no good or bad, their own characteristics are different, suitable for different application fields.

Viscose fiber is a kind of Qingsheng regenerated cellulose fiber, the raw material is wood pulp or cotton linters, and the cellulose is extracted from it through a series of physical and chemical processes to make fibers. The composition is the same as cotton, both are cellulose, and the moisture absorption is better than that of cotton. Suitable for underwear, casual, fashion**, etc.

Nylon is a kind of chemical fiber, that is, the nylon we talk about in daily life, and the fiber has very good wear resistance, so some socks will be added to blends, which are suitable for coats and other fabrics that need to be crisp and wear-resistant.

Peace and joy!
