What is the difference between rayon and rayon? In the textile industry market, the raw materials are divided into plant fiber, animal fiber, mineral fiber, chemical fiber and man-made fiber, and the first three of the raw materials are all natural compounds. It takes people to spend time planting and harvesting, and it takes a long time to get it. Therefore, chemical fibers and man-made fibers have appeared, which are products made by people using knowledge, which greatly reduces the planting time. The editor will introduce two common textile materials in man-made fibers, rayon and rayon, and check their characteristics and differences.


Common name for cotton staple fiber. The main varieties are cotton-type viscose staple fibers that are chemically processed and spun from natural polymer compounds such as cellulose or protein. Its specifications are similar to cotton fibers. The length is generally 35mm. The fineness is 1.5 to 2.2 dtex. It can be spun purely on a cotton spinning machine, or blended with cotton or cotton-type synthetic fibers (such as polyester, nylon, etc.).

Features of rayon

Advantages: good dyeability, high brightness and fastness, comfortable wearing, resistance to dilute alkali, and moisture absorption similar to cotton.

Disadvantages: it is not acid resistant, has poor resilience and fatigue resistance, and low wet mechanical strength. It can be spun purely or blended with chemical fibers such as polyester.


Rayon is a silky man-made fiber composed of cellulose, which is an organic compound that constitutes the main component of plants. Because it is a cellulose fiber, many properties are the same as those of other fibers such as cotton and flax fibers. Such fibers are tooth-shaped.

Rayon features

Advantages: viscose rayon fiber is a medium to heavy-duty fiber with average to good strength and abrasion resistance. It has hydrophilic properties (11% moisture regain). This fiber can be dry-cleaned, and it can also be washed under good care. There is no static electricity or pilling, and the price is not expensive.

Disadvantages: Rayon loses 30% to 50% of its strength when it is wet, so you need to be careful when washing it. After drying, the strength will recover (improved viscose rayon-high wet modulus (HWM) viscose Fiber, there is no such problem), rayon has poor elasticity and resilience performance, and will shrink greatly after washing, and it is also easy to mold.

The difference between rayon and rayon

Both components are viscose, rayon is viscose filament, and rayon is viscose staple fiber.

Viscose fiber is made of natural wood, reed, cotton linters and other cellulose as raw materials through chemical processing.

Viscose fiber is divided into two types: filament and short fiber.

Viscose filament is also called rayon or viscose filament; while viscose staple fiber has cotton type (also known as rayon), wool type (called rayon) and medium-length fibers.

In addition, viscose fiber can also be made into three kinds of gloss, semi-gloss and extinction.

Viscose fiber is a regenerated cellulose fiber. It uses natural cellulose as raw material to make soluble cellulose xanthate through alkalization, aging, yellowing and other processes, then dissolve it in dilute lye to make viscose, and make it by wet spinning. Using different raw materials and spinning processes, ordinary viscose fiber, high wet modulus viscose fiber and high strength viscose fiber can be obtained respectively. Ordinary viscose fiber has general physical and mechanical properties and chemical properties, and is divided into cotton type, wool type and filament type, commonly known as rayon, artificial wool and rayon. High wet modulus viscose fiber has a higher degree of polymerization, strength and wet modulus. This kind of fiber can withstand a load of 22.0cN per unit linear density in the wet state, and the wet elongation under this load does not exceed 15%, and it mainly contains rich and strong fibers. High-strength viscose fiber has high strength and fatigue resistance.

The best is not natural. Although rayon and rayon are artificially obtained by people using chemical knowledge, they are soft in texture, smooth to the touch, and look smooth and clean. They are similar to natural cotton and silk, and the price is generally not high, so they are widely used. There is no doubt in the textile industry.
