What is the difference between rayon and viscose

Rayon is a type of viscose. Rayon is also a type of viscose.

Viscose is a type of rayon, and viscose is divided into filament and staple fiber. Its main varieties are: rayon (100% viscose rayon), rayon (100% spun rayon), viscose nylon (curved bead yarn), viscose AB ply yarn.

Rayon is viscose staple fiber.

Performance characteristics of viscose fabrics.

1. The moisture absorption performance of viscose fiber fabric is the best among chemical fibers, and its wearing comfort and dyeability are better than those of synthetic fiber fabrics.

2. Viscose fabric has a soft feel and bright color, which is better than other chemical fiber fabrics. In particular, it has pure spinning and interwoven silk, brocade and other clothing made of light rayon, and its color is dazzling, the luster is soft and bright, and there is a sense of gorgeousness and nobility.

3. The drape of ordinary viscose fabric is good, the stiffness, resilience and wrinkle resistance are poor, the wet strength is only about 50, and the shrinkage rate is large, about 8 10. The shape retention and washing durability of the clothing are poor, but the ** is low.

4. The dry and wet strength of rich fiber fabrics are higher than that of ordinary viscose fabrics, and the crispness and wrinkle resistance are also good. The color is slightly less vivid.

5. Modified viscose polynosic fiber fabric has effective physical and mechanical properties and high stability to alkali, and it can be mercerized. Highwet modulus viscose fabrics have small deformation in wet state and good abrasion resistance.

Viscose staple fibre is more extensive than rayon, viscose staple fibre is to include rayon.

Viscose staple fibers.

Explanation: It is called viscose fiber, which is made of natural wood, reeds, cotton linters and other cellulose as raw materials through chemical processing.

Classification: Viscose filament and viscose staple fiber. Filament is also known as rayon or viscose filament; Staple fibers include cotton type (also known as rayon), wool type (called artificial wool) and medium and long fibers.

Rayon. Explanation: A common name for cotton-type man-made staple fibers.

The main varieties are raw materials of natural polymer compounds such as cellulose or protein that are chemically processed and spun, such as cotton-type viscose staple fibers. Its specifications are similar to those of cotton fibers. The length is generally 35mm.

The denier is. It can be spun purely on a cotton spinning machine, or blended with cotton or cotton-type synthetic fibers (such as polyester, nylon, etc.).

Classification: Rayon is also a kind of viscose product. Viscose is divided into filament and staple fiber.

Its main varieties are: rayon (100% viscose rayon), rayon (100% spun rayon), viscose nylon (curved bead yarn), viscose AB ply yarn, and rayon is viscose staple fiber.

Viscose staple fiber, also known as rayon, has good moisture absorption and soft touch. Cotton linters, wood pulp and bagasse are the main raw materials for the production of viscose fibers, which are abundant in resources and low in manufacturing costs.

The dry strength of viscose fiber is lower than that of cotton, its wet strength is only about 66% of the dry strength, the elastic recovery ability is poor, it is not wear-resistant, not light-resistant, alkali-resistant but not acid-resistant; However, viscose fiber has good moisture absorption, is easy to dye, and the fabric is comfortable to wear.

Properties of rayon:1. Good moisture absorption, soft feel, hygienic and comfortable to wear.

2. The wet strength is less than the dry strength, but the overall strength is strong and durable.

3. Good dyeing performance, soft luster and natural beauty.

4. Alkali resistant, high temperature alkali treatment can be made into mercerized cotton.

5. Poor wrinkle resistance and large shrinkage rate.

Rayon. It refers to cellulose raw materials, such as natural polymer compound synthetic materialsAfter processing, the difference between it and rayon is that the molecular weight is larger than that of ordinary cotton, giving people a more comfortable feeling, rayon is characterized by easier coloring, less difficult processing, comfortable to wear, compared with pure cotton material, its finish.

It is better and can meet people's needs for use.

Choose rayon.

1. Look at the tissue, that is, its composition, rayon is mostly plain weave, due to viscose fiber.

The strength difference is not wear-resistant, and the fabric with tight organization should be selected to increase the service life of the fabric.

2. Expand the size to ensure the use of demand, rayon is a pure viscose fabric, the shrinkage rate is generally 8% to 10%, therefore, the shrinkage rate must be taken into account before buying, and more than Luolai.

3. The scope of application is more, the elasticity of rayon is poor, the wear resistance is poor, the wrinkle resistance is poor, it is not suitable for high-end clothing such as suits, but should be made of various casual clothes, pajamas, skirts, dresses, quilt curtains and other items.

1. The nature is different.

Cotton silk is essentially a seed fiber made from the elongated and thickened epidermal cells of fertilized ovules. Its main constituent substance is cellulose.

Viscose fiber, the full name of viscose fiber, is essentially a cellulose fiber obtained by extracting and reshaping fiber molecules from natural wood cellulose.

2. Different classifications.

Cotton silk is divided into upland cotton, island cotton, Asian cotton, and grass cotton. Upland cotton is the most widely cultivated cotton species in the world, accounting for more than 90% of the world's cotton fiber production; Island cotton is known for its long and thin fibers, mercerized and high strength (grams). Commercially, it is commonly known as long-staple cotton; Asian cotton is the earliest cotton species cultivated and disseminated by humans; Grass cotton, also known commercially as coarse cotton due to its stubby and short fibers.

Viscose fibers can be divided into ordinary viscose fibers, high wet modulus viscose fibers, strong viscose fibers and modified viscose fibers. Among the high-performance viscose fibers, the fibers with a higher elastic modulus in the wet state are referred to as rich fibers. The fiber with a wet modulus between ordinary fiber and Polynosic fiber, but with higher collusion strength and less brittleness, is called improved high wet modulus fiber.

1. Hot air cotton (non-glued cotton) is a new type of insulation material, which is the replacement product of spray cotton and imitation silk cotton. Hot air cotton is different from spray cotton. Instead of using latex, the fixation method is a mixture of a certain number of low-melting or two-component fibers in the raw material, which is melted between the fibers after hot drying during the production process.

Therefore, the production speed of hot air cotton is fast, the output is large, and the cost is low.

2. Nitrocellulose: Nitrocellulose is white or yellowish cotton wool, soluble in acetone. The scientific name is cellulose nitrate, formerly known as nitrocellulose and nitrocellulose.

NC is a polymer. Its molecular weight is large. Its molecular formula is C6H7O2(ONo2)A(OH)3-AN, where A is the degree of esterification and N is the degree of polymerization.

It is customary to use the percentage of nitrogen content to represent the degree of esterification. Nitrocellulose is highly flammable and highly flammable, and its danger degree is determined according to the degree of nitrification. When the temperature exceeds 40, it can accelerate its decomposition and spontaneous combustion.

Although nitrocellulose with insufficient nitrogen content is relatively stable, it will gradually decompose and release acid when heated or stored for a long time, reducing the ignition point, and there is also the possibility of spontaneous combustion and self-explosion.

3. Pearl cotton, polyethylene foam is a non-cross-linked closed-cell structure, also known as EPE pearl cotton, is a new type of environmentally friendly packaging material. It is made up of low-density polyethylene grease that is physically foamed to produce numerous individual bubbles. It overcomes the shortcomings of ordinary styrofoam that are brittle, deformed and have poor recovery.

It has many advantages such as water and moisture resistance, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc., and also has good chemical resistance. It is an ideal alternative to traditional packaging materials.
