Viscose fabric, which is soft and lightweight, has been used in many closets and houses since the late 1800s.
Viscose is derived from trees. However, it is not as ecologically friendly as other varieties of rayon, such as modal, due to the high amounts of chemicals used in the manufacturing process.
Viscose is a versatile fabric used in clothes such as blouses, dresses, and jackets, as well as carpets and upholstery.
Is Viscose Stretchy?
Viscose is a cellulose fiber that has been regenerated. Viscose is a synthetic fiber from wood pulp that has been chemically treated to dissolve into a solution.
The solution is then extruded through microscopic pores to create thin fiber strands. Because it is lightweight and breathable, it is frequently used in athletic wear and other clothes. But one of the nicest things about viscose is how elastic it is!
Understanding Viscose
Viscose Manufacturing Process
Preparation Of Wood Pulp
First, the bark of the wood is removed and broken into small pieces around an inch in size. The chips are then treated with calcium bisulfite [Ca(HSO)2] before being processed with steam under pressure for around 14 hours. These treatments have little effect on the cellulose, but they degrade and solubilize the smearing chemicals.
Steeping And Pressing
The paper boards or sheets contain 90 to 94% pure cellulose. Conditioning in space at a specific humidity and temperature. This conditioning is required. The boards or sheets are vertically stacked and pressed before being immersed in a 17.5% caustic soda solution for 1-4 hours.
Shredding Machines
They have a drum inside which a pair of serrated-edged blades revolve. The shredders are water-cooled and can handle 200 pounds of squeezed soda cellulose at a time. They break it up into very fine “Crumbs” (break into very little fragments) in about two or three hours.
Aging
When the shredding is finished, the crumbs are aged. They were maintained in a galvanized jar with a cap, and degradative changes occurred due to oxidation with ambient oxygen. In this process, some depolymerization happens, and the degree of polymerization decreases from around 780 to 360.
Churning
Following the end of the aging process, the soda cellulose (Cell – ONa) crumbs are placed in rotating airtight hexagonal churns. Approximately 10% of their own (crumbs) weight of carbon disulfide (CS2) is injected, and the crumbs and disulfide are churned together to generate a bright orange, gelatinous mass of sodium cellulose Xanthate.
Mixing (Solution)
Swirling sodium cellulose xanthate [C6H7O2(OH)2OCS2Na] with dilute caustic soda for 4 to 5 hours while the vessel cools. The xanthate dissolves to a clear-brown, thick liquid that resembles honey. This liquid is called “Viscose,” but it is still too impure and young to spin.
Ripening
The viscose solution is ripened at 10o-18oC for 4 to 5 days. Meanwhile, the viscosity first decreases but then increases, increasing by the time the solution is ready to spin. The spun ability viscose ripening test is provided below –
Properties Of Viscose
- Absorbent: Viscose rayon does not retain heat but absorbs water and sweat well, making it an excellent choice for t-shirts and sporting wear.
- Lightweight: Viscose is light and airy, ideal for blouses and summer dresses.
- Breathable: It’s a very light fabric that doesn’t adhere to the body, making it ideal for summer clothes.
- Soft: While the material appears to be silk, it is cotton.

Factors Affecting The Stretchability Of Fabrics
Absorption Of Moisture: Viscose rayon absorbs moisture more than cotton; at 65% R.H. and 70oF temperature, the moisture content of viscose rayon is roughly 13%.
Tensile Strength: The fiber is stronger when it is dry than wet. Viscose rayon has a tensile strength of 1.5 to 2.4 GPD (gram per denier) in the dry state and 0.7-1.2 GPD in the wet condition. The comparable values for high-tenacity viscose rayon are 3-4.6 GPD and 1.9-3.0 GPD, respectively.
Flexibility: Viscose rayon has an elasticity of less than 2-3%, after which creep begins, and irreversible elongation sets in until the yarn breaks.
Break Lengthening: When the yarn is wet, regular viscose rayon has 15-30% elongation at break, but high tenacity rayon has only 9-17% elongation at break; it is easier to stretch and has higher elongation – 20-35% for ordinary and 14-20% for high tenacity viscose.
Applications And Benefits Of Stretchy Viscose
- Because of its incredibly absorbent properties, it is an excellent choice for sportswear that does not retain heat.
- It has high colour retention and can keep the dye color even after multiple washes.
- The answer to the question of whether viscose fabric wrinkles is yes. Viscose has a silky texture and may be pleated elegantly.
- Low permeability should not be the cause of allergies.
Tips To Clean Viscose fabric
Hand Washing
- To keep the color and texture of your viscose garment, turn it inside out before washing.
- Brush your teeth. Simply touching the clothing with your hands will remove any dirt.
- Rinse with cold water after a few minutes to remove the detergent.
- Rinse with clean water until the soap suds no longer froth.
Natural Drying
- To expedite drying, lay your viscose clothing flat or hang them in a well-ventilated place.
- Pegs should be avoided since they can leave an imprint. Get a hanger instead.
- Turn the garment inside out while drying it in the sun to maintain the color. When dry, the cloth will recover its smooth, silky feel.
Maintaining The Stretchiness Of Viscose Fabric
Normal Heating
Avoid applying direct heat to the fabric for a lengthy period of time, as this may cause discoloration or burning. To protect the fabric, use a pressing cloth or a towel. Heat the cloth briefly, examining it periodically to ensure it is not harmed.
Improve Your Results By Including A Stretchy Panel
- Adding a stretchy panel is an excellent way to add stretch to a garment composed of a non-stretchy fabric, such as viscose. This procedure can also produce a one-of-a-kind design element for the garment.
- Skelling skills are required to accomplish this procedure effectively, or you can visit a skilled tailor or seamstress.
- Choose the stretch panel carefully to match the overall texture and weight of the garment for a seamless and comfortable fit.
Hand Stretching Fabric
Another method for properly fitting your project is to stretch viscose cloth by hand. To stretch the fabric, first lay it flat on a level surface and gently tug on the corners or edges. It’s critical not to use too much power or pull unevenly since this might cause the fabric to break or change the contour of your item.
This approach needs more care and attention to detail for smaller jobs than a fabric stretcher. Handle your cloth carefully to ensure it is stretched to the proper length without damaging its integrity. Give it a shot and see what a difference it may make.
What Is Viscose Bamboo Fabric?
Bamboo viscose is created from a viscous mixture of cellulose fibers, as the name implies. The primary purpose of viscose textiles is to mimic silk. Although the basic ingredients used to produce viscose are natural, the end result is semi-synthetic since such mixtures do not exist in nature. Bamboo is not the only material utilized in the manufacture of viscose fabrics. Viscose textiles can also be made from hemp, wool, and cotton.
Viscose is a name used in the textile business to describe a process that has existed since the late 1800s. The original patent sheds information on the intentions of its founders, two British chemical engineers who attempted to create silk artificially. We make viscose derived from their processes.
Is Viscose Breathable?
Because it is manufactured from a wood pulp solution that is knit or woven into a lightweight fabric, viscose is breathable. It absorbs moisture, which keeps your skin cool, and the microscopic gaps in the fiber allow air and water to travel through. Viscose mixes can also increase the breathability of other materials.
This adaptable, cheap fabric was designed to feel like a luxury cloth instead of silk. It is now utilized in a wide range of clothes, but it isn’t always the greatest choice because of its moisture retention and fragility. This tutorial will identify and describe the finest applications for viscose fabric.
Is Viscose A Summer Fabric?
Viscose, halfway between silk and cotton, is extremely pleasant to wear in summer and winter. This fabric is silky, glossy, and lofty!
