The complicated manufacturing process raises many questions around viscose fabric. Is this a man-made fiber or a natural fiber? Are Viscose and Modal the same thing? Let’s find out the answer with Green Cushion in the article below.

What is Viscose Fabric?
Viscose fabric Also known as Rayon is a synthetic fiber. The material used to make fibers is the fiber of cellulose fibers regenerated from trees such as soybean, sugarcane, bamboo, etc. Viscose has a structure similar to cotton and is widely used in many fields.
Viscose fabric first appeared in Europe around the 1800s. The high cost and high technology of silk required manufacturers to find new directions to reach customers in the segment. Common. Scientist and industrialist Hilaire de Chardonnet has invented a material with quite similar properties such as smoothness, inelasticity. Experiments carried out subsequently resulted in commercialized viscose fabric as a substitute for silk.
By 1892, viscose fabric was patented for the manufacturing process. Three British scientists Charles Frederick Cross, Edward John Bevan and Clayton Beadle are the authors of this study. Viscose fabric was officially introduced to the market in 1905.
Most viscose production was formerly produced in the US and UK. Due to cheap labor and less stringent production regulations, much of this production is shifted to developing countries. Currently, countries like India, Paskintan, Indonesia, China have the largest market share of viscose in the world.
Viscose fabric production process
Production process viscose fabric Relatively complex requires high technical skills. Fabrics are often made in large-scale factories with dozens of different chemicals and machines. Depending on the purpose, manufacturers can reduce additives or add other fibers to optimize product performance. The basic steps are as follows:
Step 1: The input cellulose material is milled, dissolved with some chemicals such as sodium hydroxide to form an alkaline cellulose solution with a wood brown color. Impurities are removed in this process. To achieve purity, the percentage of cellulose must reach 90%.Step 2: Alkaline cellulose is forced through rollers to remove excess. The press plates are cut into many small pieces.Step 3: The powder is further treated with carbon disulfide and then dissolved in sodium hydroxide. The end product of this process is called viscose. Chung continues to be dissolved and soaked for several hours.Step 4: The condensed solution is pushed through the extruder to create viscose fibers. These are called cellulose derivatives. The yarn is soaked in sulfuric acid solution, then put the scissors and washed. Step 3: The yarn is spun into yarn and then woven into fabric. The final product is packaged for consumption or transferred to the design stage.
Features of viscose fabric
Breathable and effective moisture absorption
The dense texture and moderate thinness help the viscose have effective breathability. As a result, the phenomenon of mold and micro-organism growth is minimized. This feature of the fabric is not inferior to that of cotton. When used, the fabric does not stick to the skin and is not electrically charged, so it is suitable for use in summer wear such as T-shirts, sportswear.
Considered a substitute for silk, viscose fabric has an impressive shine and softness. Pain and discomfort caused by rough surfaces are minimized when using this product.
Resistance to acids
Viscose is resistant to acids. The viscose clothes also keep their shape quite well, you can use the washing machine to save effort and cleaning time.
Easy to dye
Because it is synthesized from many different substances, viscose fabric is optimized for color fastness, easy dyeing, and less fading.
Easy to design
Viscose fabric has a moderate softness and thinness, so it is easy to design. The surface is not too smooth so that designers can use their hands to hold hands, not requiring too much meticulousness because of paper clips like chiffon or chifon.
Reality, viscose fabric uses natural wood pulp and is made from renewable resources so it is biodegradable. At the same time, their recyclability is also much higher than that of man-made fabrics such as nylon and polyster.
The production process of viscose fabric has always been an environmental problem. It is estimated that only 30% of viscose has devastated many ancient forests. This has greatly threatened the habitat of native animals, negatively affecting the natural ecosystem.
To produce viscose, it is necessary to use high concentrations of chemicals that pollute the air and water. The substances used can be mentioned as sulfur, sulfuric acid, carbon, etc. Although it is reused many times in the production cycle, it is still not a perfect method compared to other materials such as modal, tencel. These chemicals are still found in exhaust gases at manufacturing plants.

Easy to relax
Viscose fabric is not too durable, easy to stretch and difficult to restore to its original shape. In particular, they are quite loving in the wet state, making the recovery process even more difficult. Special attention should be paid to the use process to avoid stains that require the use of strong detergents or repeated washing.
Because it is made from wood pulp, viscose fabric is very flammable. The wear resistance of the fabric is also very poor.
Difficult to clean
Viscose fabric is quite hydrophobic, making cleaning complicated. Most products made from this material require dry cleaning.
Classification of viscose fabric
This is the largest amount of fabric on the market. This material is often used in the garment industry and home furniture production. They wrinkle easily when wet. You should bring it to a professional launderette to keep the best quality for the fabric.
HWM Rayon impresses customers with its superior moisture absorption capacity. The flexible nature of the fabric facilitates the polishing process. Moreover, you can freely choose to machine wash or hand wash for products using this material.
High Durability Rayon
High-strength Rayon is mainly used in industrial textiles that require durability and withstand large loads or products such as tires, car belts. It is the perfect solution to replace cotton thanks to its low cost and higher durability. They are often coated with rubber or chemicals to prevent moisture or to fix the structure.
Application of viscose fabric
Application in the garment industry
Viscose fabric is widely used in the textile industry to replace silk and reduce production costs. Products using this material include ski wear, casual wear, shirts, light jackets. In addition, the fabric is also used to create bed sheets, blankets and curtains.
Thanks to its flexibility in production and low cost, viscose is used in many other fields such as cellophane production, sausage casings, tires, automobile belts, etc.
How to clean and maintain viscose fabric
Wash the viscose by hand and use cold water.Do not wring, curl or crease the fabric. Use a cotton towel to absorb all the water after washing. Next, hang the viscose fabric on the hook, smooth it and let it dry naturally. If washing by machine, choose a gentle mode. The large speed of the rotating chamber can make the fabric easily stretch and deform. Use detergents, mild soaps with low pH, low foam, low alkali to avoid breaking the fabric structure. You can use organic soap for this.
Distinguish viscose fabric
While there are many similarities in manufacturing process and properties, there are still many major differences between viscose, modal and polyester.
Difference between viscose and polyester
The fiber structure of these two materials is quite long, but polyester is a synthetic fiber that is mixed from many different fibers. In contrast, viscose is considered a semi-synthetic fabric that is made with bio-fibers but uses chemicals in the manufacturing process. Polyester absorbs more moisture while viscose absorbs them more. Polyester dries faster and doesn’t wrinkle as easily. viscosePolyester is stronger and does not shrink during cleaning and use.Polyester is made from petroleum while viscose is of vegetable origin.Viscose has good acid resistance but polyester is resistant to abrasion.

Difference between viscose and modal
Modal holds better strength and does not deform when wet like viscose. Their manufacturing process is almost the same but the more processed viscose fiber ensures a stronger, lighter texture and better breathability. more.Modal is more environmentally friendly than viscose because it uses a much lower concentration of sodium hydroxide.
