When shopping for clothing or textiles, you might have come across the term “viscose” and wondered if it’s a natural fiber. The truth is, viscose is often misunderstood as being a man-made material, but its origins are actually rooted in nature. However, its production process has raised some eyebrows among eco-conscious consumers.
In this article, we’ll delve into the world of viscose fibers to separate fact from fiction. We’ll explore where viscose comes from, how it’s made, and whether or not it can be considered a natural fiber at all. By understanding the complexities surrounding viscose, you’ll be better equipped to make informed choices about the clothes you buy and the impact they have on the environment.
What is Viscose?
Let’s start by breaking down what viscose actually is: a semi-synthetic fiber made from wood pulp cellulose, often misunderstood as natural. We’ll explore its composition in more detail here.
Definition and Origins
Viscose has its roots in natural materials like wood pulp, which was first used to produce this synthetic fiber over a century ago. The production process of viscose involves breaking down plant-based raw materials into their component parts. Wood pulp is typically harvested from sustainably managed forests or plantations and then processed to create a pulp.
This pulp is then dissolved in a chemical solution called sodium hydroxide, creating a viscous liquid known as viscose. This liquid is then extruded through spinnerets, which give it the characteristic fibers of viscose fabric.
Viscose was first developed in the early 20th century and quickly became popular for its softness, durability, and affordability. In the 1930s, viscose began to be used extensively in textile production, particularly for clothing, bedding, and upholstery. The unique properties of viscose made it an attractive option for manufacturers looking for a fabric that was both gentle on skin and easy to clean.
Today, while some producers have started using recycled materials or alternative raw materials like bamboo, the fundamental process remains largely unchanged from its inception.
Production Process
The production process of viscose fibers involves several steps that convert wood pulp or cotton linters into a soft, silky material. To begin, wood chips are harvested and processed into pulp, which is then mixed with sodium hydroxide to create a viscous solution. This mixture is then extruded through a spinneret, creating long, thin filaments of cellulose.
The newly formed fibers undergo various chemical treatments, including carbonization and bleaching, to enhance their texture and appearance. Bleaching agents like hydrogen peroxide or sodium perborate are used to whiten the fibers, while other chemicals may be added to give viscose its characteristic sheen.
However, this process raises environmental concerns due to the significant amount of water required and potential chemical contamination. Furthermore, the use of non-renewable resources, such as wood pulp, contributes to the industry’s carbon footprint. As consumers become increasingly aware of sustainability issues, manufacturers are exploring eco-friendly alternatives, including using recycled materials or plant-based dyes.
Properties and Characteristics of Viscose
So, you’re curious about the properties and characteristics that make viscose a unique fiber. Let’s explore its texture, breathability, and durability in more detail.
Physical Properties
Viscose fibers are known for their unique physical properties that make them a popular choice in the textile industry. When it comes to texture and softness, viscose is often described as smooth and silky to the touch. This is due to its semi-synthetic composition, which gives it a more refined feel compared to natural fibers like cotton or wool.
One of the advantages of viscose is its ability to blend with other fibers, allowing manufacturers to create fabrics that combine the benefits of multiple materials. For instance, blending viscose with spandex can enhance its elasticity and stretchiness, making it ideal for activewear. On the other hand, pairing it with cotton or linen can add a more natural and breathable feel to the fabric.
In addition to its softness and blendability, viscose also boasts impressive moisture-wicking abilities and breathability. This makes it an excellent choice for clothing that requires both comfort and functionality, such as sportswear or outdoor gear. In fact, many top brands have successfully incorporated viscose into their collections due to its ability to keep wearers cool and dry in warm conditions.
Chemical Composition
Viscose is primarily composed of cellulose, typically derived from wood pulp or cotton linters. The chemical composition of viscose involves a process called regeneration, where the cellulose fibers are dissolved in a solution and then reformed into new fibers. This regeneration process allows for some control over the final product’s properties.
One key characteristic of viscose is its ability to interact with chemicals and finishes used in textile processing. Viscose fibers can be easily dyed and finished with various treatments, such as softeners or wrinkle-resistants. However, this also means that viscose may absorb and retain chemicals, potentially affecting the wearer’s skin.
In terms of durability, viscose fibers tend to be less resistant to wrinkles and creases than other natural fibers like wool or silk. This is because viscose fibers are more prone to compression and can become distorted when subjected to mechanical stress. Nevertheless, some viscoes exhibit decent wrinkle resistance due to the addition of synthetic polymers during manufacturing.
Natural vs. Synthetic Fibers: Debunking Misconceptions
Viscose is often misunderstood as a natural fiber, but does it really live up to its reputation? Let’s dive into the truth behind this popular fabric.
The “Natural” Label
When it comes to fibers labeled as “natural,” there’s often an assumption that they’re inherently better for the environment. However, what exactly does this term mean? In reality, a natural fiber is one that’s derived from plants, animals, or minerals through a process that doesn’t involve chemical manipulation.
To break it down further: natural fibers like cotton and wool come directly from nature, while semi-synthetic fibers, such as viscose (made from wood pulp), undergo some processing before being spun into yarn. On the other hand, synthetic fibers – polyester, nylon, etc. – are created entirely in a lab using petroleum-based materials.
Now, it’s worth noting that a fiber’s natural origins don’t necessarily determine its eco-friendliness. Viscose, for instance, may start as wood pulp but still requires significant processing and energy to produce the final product. This has led many experts to argue that semi-synthetic fibers like viscose are not as environmentally friendly as they seem. In fact, studies suggest that the production of viscose generates more greenhouse gas emissions than traditional cotton farming.
Sustainability Concerns
When it comes to sustainability concerns, viscose production raises some red flags. The process of turning wood pulp into fibers requires massive amounts of energy and water, leading to significant environmental impacts. For instance, a single ton of viscose production generates around 50-70 kilograms of CO2 emissions – that’s equivalent to driving a car for about 150 miles.
Comparing the sustainability credentials of different fibers is crucial in this context. Cotton, often touted as an eco-friendly option, requires copious amounts of water (around 2,500 gallons per pound) and pesticides, which can pollute soil and waterways. On the other hand, polyester production relies heavily on non-renewable resources like petroleum and natural gas.
In contrast, Tencel – a branded lyocell fiber made from wood pulp cellulose – is often hailed as a more sustainable alternative to viscose. Tencel production uses a closed-loop system that recovers up to 99% of the solvent used in the process, minimizing waste and emissions. While not perfect, Tencel’s environmental credentials are certainly more impressive than those of traditional viscose. If you’re looking for an eco-friendly option, consider choosing clothing made from sustainable fibers like Tencel or recycled polyester.

Environmental Factors
When it comes to the environmental impact of viscose production, a lifecycle assessment reveals some concerning trends. From raw material sourcing to end-of-life recycling, the entire process contributes significantly to greenhouse gas emissions and pollution. The primary source of viscose is wood pulp from trees such as eucalyptus or birch. However, deforestation and monoculture farming practices often lead to soil erosion and water depletion.
Moreover, the production process itself involves significant energy consumption and chemical use, resulting in air and water pollution. For instance, a ton of viscose production generates around 2-3 tons of carbon dioxide equivalent emissions, primarily due to fossil fuel combustion during cellulose extraction and spinning.
Despite these challenges, the industry is taking steps towards reducing waste and adopting eco-friendly practices. Some manufacturers are transitioning to more sustainable wood sources or implementing recycling programs for post-consumer products. For example, Lenzing AG has implemented a closed-loop system where old products can be collected and recycled into new fibers.
Social Responsibility and Industry Practices
When it comes to viscose production, several social concerns arise due to labor conditions in countries where viscose is primarily manufactured. The textile industry has been criticized for its poor working conditions, including low wages, long hours, and hazardous environments. In some cases, workers have reported being exposed to toxic chemicals without proper protective gear.
However, many companies within the textile industry are taking steps towards more sustainable production methods. Some initiatives include improving labor conditions, reducing water waste, and implementing recycling programs for leftover materials. Companies like Patagonia and H&M have committed to using environmentally-friendly materials and fair labor practices in their supply chains.
For consumers who want to make responsible choices, there are several options available. Look for brands that prioritize sustainable production methods and provide transparency into their manufacturing processes. Some certifications, such as the Global Organic Textile Standard (GOTS), can also help identify products made with environmentally-friendly materials. By choosing brands that align with your values, you can contribute to a more equitable and sustainable industry.
