What Is Viscose and How Is It Made?
Origins and Composition of Viscose
Viscose is a semi-synthetic fiber made from cellulose, primarily derived from wood pulp. Manufacturers typically source this cellulose from fast-growing trees like eucalyptus, beech, and pine. The resulting fabric is soft, breathable, and often compared to silk for its smooth texture. Interestingly, viscose is technically a type of rayon, but not all rayon is viscose.
Key points about viscose composition:
- Derived from natural cellulose, making it partially plant-based.
- Known for its silk-like appearance and feel.
- Often used in clothing, upholstery, and household items.
The Manufacturing Process Explained
The production of viscose involves a complex chemical process that transforms wood pulp into a versatile fiber. Here’s a simplified breakdown of the main steps:
- Steeping: Wood pulp is soaked in sodium hydroxide to create alkali cellulose.
- Shredding: The alkali cellulose is shredded into small pieces to increase its surface area.
- Aging: This shredded material is left to age, reducing the length of its polymer chains.
- Xanthation: The aged cellulose reacts with carbon disulfide, forming cellulose xanthate.
- Dissolving: The xanthate is dissolved in a sodium hydroxide solution, creating a viscous liquid.
- Spinning: This solution is filtered, then extruded through spinnerets into a coagulating bath, forming fibers.
While this process creates a fabric that’s loved for its versatility, it’s not without environmental concerns due to the use of toxic chemicals like carbon disulfide.
Key Characteristics of Viscose
Viscose stands out for its unique combination of properties, making it a popular choice in various industries. Here are some of its most notable characteristics:

- Breathability: Viscose is lightweight and wicks moisture, making it ideal for warm weather.
- Versatility: Used in everything from summer dresses to upholstery and even industrial materials.
- Color Retention: It absorbs dyes well, resulting in vibrant, long-lasting colors.
Viscose is often marketed as a sustainable alternative to synthetic fabrics, but its production process raises questions about its true environmental impact. Understanding how it’s made is the first step in making informed choices about this widely used material.
Environmental Concerns Surrounding Viscose
Deforestation and Habitat Loss
Viscose production starts with wood pulp, and the demand for this raw material has led to significant deforestation. Forests, including endangered rainforests, are often cleared to make way for plantations, threatening biodiversity and displacing wildlife. This loss of forest cover also impacts local communities who depend on these ecosystems for their livelihoods. Unsustainable sourcing practices exacerbate this issue, but some companies are beginning to adopt wood from responsibly managed forests to mitigate these effects.
Chemical Usage and Pollution
The manufacturing process for viscose relies heavily on chemicals like carbon disulfide, sulfuric acid, and caustic soda. These substances can be highly toxic if not handled properly, posing risks to both workers’ health and the environment. Factories that fail to manage waste effectively may release these chemicals into nearby water bodies, polluting ecosystems and harming aquatic life. Air emissions, including sulfur and nitrous oxides, add to the environmental burden, contributing to poor air quality and climate change.
Water and Energy Consumption
Producing viscose is water-intensive, requiring up to 30 tons of water for every ton of fabric. This can exacerbate water scarcity in regions already struggling with limited resources. Energy use is another concern, as viscose production often relies on non-renewable energy sources, increasing its carbon footprint. While some manufacturers are working to reduce water and energy usage, the industry as a whole still has a long way to go in addressing these challenges.
The environmental impact of viscose is undeniable, but innovations like ECOVERO™ and other sustainable alternatives are paving the way for a more eco-conscious future.
Is Viscose Biodegradable and Eco-Friendly?
Biodegradability of Viscose
Viscose is often praised for being a more natural alternative to fully synthetic fabrics, but its biodegradability isn’t as straightforward as it might seem. While viscose is derived from wood pulp, a plant-based material, its processing involves heavy chemical treatments. These treatments can leave residues that impact how quickly and safely the fabric breaks down in the environment. Under ideal conditions, viscose can decompose within weeks to a few months. However, if it ends up in landfills or environments lacking proper conditions—like oxygen and moisture—it might take years to degrade.
Comparison with Synthetic Fabrics
When compared to synthetic fabrics like polyester or nylon, viscose is definitely more biodegradable. Polyester, for example, can take hundreds of years to break down, while viscose has a much shorter timeline. On the flip side, synthetics tend to last longer during use, which can reduce the frequency of disposal. This durability can make synthetics seem less wasteful in certain contexts, even though they contribute to long-term pollution.
Challenges in Recycling Viscose
Recycling viscose is not a simple process. Unlike materials like cotton or polyester, which have more established recycling systems, viscose often gets mixed with other fibers in clothing, making separation difficult. Additionally, the chemical-heavy production process doesn’t lend itself well to being reversed or reused. This means most viscose products, once discarded, are unlikely to find a second life through recycling.
The eco-friendliness of viscose largely depends on how it’s sourced and processed. If brands commit to sustainable practices, like responsible sourcing and reduced chemical use, viscose can be a greener choice.
By opting for environmentally-friendly viscose options, consumers can support brands that are working to minimize the negative impacts of this versatile fabric.
Sustainable Alternatives to Viscose
Introduction to Lyocell and Modal
Lyocell and Modal are two standout alternatives to viscose, both derived from plant-based cellulose. Lyocell, often branded as TENCEL™, is created using a closed-loop process, which means the chemicals used during its production are captured and reused, significantly reducing environmental harm. Modal, on the other hand, is made from beech trees and is known for its softness and durability. Both these fabrics are biodegradable and require less water and energy compared to viscose during manufacturing.
The Role of Bamboo Viscose
Bamboo viscose is often marketed as eco-friendly, but its sustainability depends on how it’s made. Conventional bamboo viscose production involves heavy chemical use, similar to regular viscose. However, bamboo processed through a closed-loop Lyocell method, sometimes called bamboo Lyocell, is a much greener option. It combines bamboo’s natural abundance with a cleaner production process, making it a promising alternative if sourced responsibly.
