Viscose nonwoven is a fabric made from regenerated cellulose fibers that are bonded together without weaving or knitting. Because viscose starts as wood or plant pulp and gets dissolved and reformed into fibers, the resulting nonwoven material is highly absorbent, soft against skin, and biodegradable in ways that synthetic nonwovens are not. You encounter it in wet wipes, surgical dressings, cosmetic pads, baby care products, and increasingly in agricultural applications, though many people handle it daily without ever knowing what it is.
How Viscose Nonwoven Is Made
The story begins with cellulose. Manufacturers take wood pulp (or sometimes bamboo or cotton linter pulp) and dissolve it in a chemical bath to create a thick liquid called viscose. That liquid gets forced through tiny holes to form continuous filaments, which are then cut into staple fibers. The production chain runs from raw material cultivation through pulping, chemical treatment, and spinning to produce the final viscose fiber.1Industrial Crops and Products. A comparative life cycle assessment of viscose fibers derived from cotton, wood, and bamboo pulp
Once you have loose viscose fibers, they need to become a fabric. In nonwoven manufacturing, fibers are laid into a web and then bonded. The most common bonding method for viscose nonwovens is spunlacing (also called hydroentangling), where high-pressure water jets physically tangle the fibers together without any adhesive or heat melting. This preserves the fiber’s natural softness and absorbency. Before those fibers reach the web-forming stage, they typically receive a finish treatment that acts as a lubricant and antistatic agent, helping them move smoothly through processing equipment like carding machines.2International Nonwovens Journal. Role of Fiber Finish in the Conversion of Fiber to Nonwovens — Part 1: Need for an Unconventional Method to Evaluate Finish Performance as a Mechanical Process Aid
Other bonding methods exist too. Needle-punching uses barbed needles instead of water jets. Thermal bonding uses heat to melt a synthetic component, which is why viscose is sometimes blended with a small proportion of polypropylene or polyester fibers that act as a binder. The choice of bonding process, the jet pressure used in spunlacing, and even the angle at which fiber webs are layered all affect the final fabric’s pore size and density.3Textile Research Journal. Investigation of moisture transfer properties of viscose and polyester fibers in spunlaced nonwoven wound dressings
Why Viscose Nonwovens Excel at Absorbing Moisture
The defining property of viscose nonwoven, and the reason it dominates the wet wipe and hygiene markets, is its ability to soak up and hold water. Viscose fibers are hydrophilic by nature: the cellulose molecules in each fiber attract and bind water molecules readily. When these fibers are arranged into a nonwoven web, the spaces between fibers create a network of tiny capillaries that pull liquid inward through wicking.
Research on viscose/polypropylene blended nonwovens shows that water absorptive capacity, capillary rise, and water retention all increase with higher viscose fiber content. The web bonding method and pore structure also play a role, so manufacturers can tune these properties by adjusting production parameters.4Journal of Polymer Science Part B: Polymer Physics. Multipurpose nonwoven viscose/polypropylene fabrics: Effect of fabric characteristics on sorption and dielectric properties A fabric with more viscose and smaller, more uniform pores generally holds more liquid and releases it more evenly.
The trade-off is mechanical strength. Viscose fibers lose a significant portion of their tensile strength when wet. Early studies on nonwoven viscose fabrics documented this clearly, measuring substantial differences between dry and wet tenacity, elongation, and elastic behavior.5Textile Research Journal. Studies of Nonwovens This is why pure viscose nonwovens often feel fragile when soaking wet, and why many commercial products blend viscose with a small percentage of synthetic fibers to keep the fabric from falling apart during use.
Where You Encounter Viscose Nonwovens
The largest market for viscose nonwovens by volume is personal care and hygiene. Facial cleansing wipes, baby wipes, disinfecting surface wipes, makeup remover pads, and feminine hygiene products all frequently use viscose nonwoven as the base substrate. The material’s softness makes it comfortable against skin, while its absorbency means it can carry and release a cleaning or moisturizing solution effectively.
In the medical field, viscose nonwovens serve as wound dressings, surgical drapes, and swabs. A wound dressing made from nonwoven viscose fabric treated with chitosan, polyvinyl alcohol, and silver nanoparticles achieved complete wound healing in 21 days in animal studies, with full re-formation of the outer skin layer confirmed by tissue examination.6Carbohydrate Polymers. Wound dressing based on nonwoven viscose fabrics The viscose base provides a moist wound environment and good contact with the skin surface, while the added antimicrobial agents prevent infection. Viscose’s biocompatibility and absorbency make it a natural fit for this role.
A less obvious application is agriculture. Viscose nonwoven mulch mats are laid over soil to suppress weeds, retain moisture, and protect seedlings. Because viscose biodegrades in soil, farmers do not need to remove and dispose of these mulches the way they would plastic film. Field studies confirm that viscose nonwoven mulches boost soil moisture retention, which is particularly valuable in dry climates.7Scientific Reports. Effects of field conditions on the degradation of cellulose-based and PLA nonwoven mulches
The Flushable Wipes Problem
One of the most contentious issues around viscose nonwovens is the “flushable” wipe. Wipes marketed as flushable are usually made from viscose or viscose-blend nonwoven because the material is expected to break apart in water, unlike polyester-based wipes that remain intact indefinitely in sewage systems. In principle, a dry viscose spunlace fabric disperses well: testing shows initial dispersibility above 70%.
The problem is that these wipes are not sold dry. They sit in sealed packages soaking in liquid for weeks or months before anyone uses them. Research has found that this wet storage dramatically reduces how easily the fabric breaks apart. After just two weeks of wet storage, dispersibility dropped below 10%, regardless of whether the wipes were stored in water or lotion.8Scientific Reports. Reduced dispersibility of flushable wet wipes after wet storage The water itself causes the cellulose fibers to form stronger hydrogen bonds with each other over time, essentially solidifying the web. So a wipe that would have fallen apart easily if flushed dry becomes a stubborn, cohesive sheet by the time you pull it from the package. This finding helps explain why “flushable” wipes still clog sewer systems and create the infamous fatbergs that plague municipal water infrastructure.
Biodegradability and What Happens to Shed Fibers
Viscose nonwoven’s environmental reputation rests heavily on one fact: it biodegrades. In marine environments, viscose rayon breaks down readily, while synthetic fibers like polyester, nylon, and polypropylene show virtually no biodegradation under the same conditions.9Water, Air, & Soil Pollution. Marine Biodegradation Behavior of Wool and Other Textile Fibers In soil, the story is similar: viscose nonwoven mulches decompose over a growing season, returning their cellulose to the earth.
But biodegradability does not mean zero environmental footprint. All fabrics shed tiny fibers during washing and use, and viscose-based fabrics actually release more microfibers per gram of fabric during laundering than polyester. In accelerated wash tests, cellulose-based fabrics shed roughly 0.2 to 4 milligrams of microfibers per gram of fabric, compared to 0.1 to 1 milligram per gram for polyester. Higher water temperatures and detergent use increased shedding for both types. The critical difference is what happens after those fibers reach waterways: cotton and rayon microfibers biodegrade in aquatic environments, while polyester microfibers persist for long periods.10PubMed. Microfibers generated from the laundering of cotton, rayon and polyester based fabrics and their aquatic biodegradation
So viscose nonwovens shed more fiber fragments, but those fragments actually disappear from the environment. Synthetic nonwovens shed fewer fragments, but those fragments accumulate indefinitely. Whether you consider that a net win for viscose depends on how much weight you put on the total volume of microfibers entering waterways versus how long those fibers persist once they arrive.
The Manufacturing Footprint
The viscose process has a well-known pollution problem: carbon disulfide. This toxic chemical is essential to the conventional viscose process, where it converts cellulose into the dissolved form that can be spun into fibers. Workers in viscose plants face occupational exposure, and the waste gas that exits spinning halls contains both carbon disulfide and hydrogen sulfide. Measurements in one Chinese viscose factory found carbon disulfide concentrations averaging around 14 to 20 milligrams per cubic meter in different production areas.11PubMed. The cross-sectional study of the health effects of occupational exposure to carbon disulfide in a Chinese viscose plant
Industry has developed ways to capture these emissions. Activated carbon systems can strip carbon disulfide from exhaust air and recover it for reuse.12Environmental Progress. Control of carbon disulfide emissions from viscose processes Biological filtration systems offer another approach: pilot-scale biotrickling filters have achieved steady removal of over 70% of carbon disulfide and over 90% of hydrogen sulfide from factory exhaust, even as pollutant concentrations fluctuate widely.13Journal of Cleaner Production. Simultaneous removal of carbon disulfide and hydrogen sulfide from viscose fibre waste gas with a biotrickling filter in pilot scale Still, not all viscose plants worldwide have adopted these technologies, and the gap between best practice and average practice remains wide.
Life cycle assessments comparing bio-based wet wipes (viscose or similar cellulosic materials) with petroleum-based ones (polyester or polypropylene) find that the bio-based versions have roughly 38% lower overall environmental impact across their full life cycle. The bio-based wipes perform better on resource consumption and toxicity, though they can contribute more to water pollution during manufacturing.14Resources, Conservation and Recycling. Life-cycle environmental impact assessment and plastic pollution prevention measures of wet wipes The takeaway is that viscose nonwovens are not pollution-free, but they impose a lighter environmental burden than their synthetic counterparts when you account for the entire chain from raw material to disposal.
Giving Viscose Nonwovens New Capabilities
Plain viscose nonwoven has some inherent weaknesses that limit where it can be used. It burns easily, it does not repel water, and it has no built-in antimicrobial properties. A wave of recent research has focused on surface treatments that add these missing functions without giving up the fabric’s softness or biodegradability.
One approach uses tea polyphenols combined with phytic acid to create a multifunctional finishing agent. Applied to viscose fabric, this treatment pushed the limiting oxygen index (a measure of how much oxygen is needed to sustain burning) up to about 33%, cut peak heat release by 90%, and added effective antibacterial activity against common pathogens. It also improved UV protection substantially, raising the fabric’s ultraviolet protection factor to over 50, and even made the fabric more hydrophobic. The treated fabric actually became stronger, with breaking force retention exceeding 130% in both directions.15Composites Part B: Engineering. Multi-functional finishing of viscose fabrics based on tea polyphenols: Integrated flame retardant, antibacterial, hydrophobic, and UV-resistant functionalities
Another strategy builds a phosphazene-based hybrid coating onto viscose fabric through a one-step process. This coating integrates flame-retardant chemistry with antimicrobial and hydrophobic properties by combining a phosphazene compound with silane and silica nanoparticles. The coating forms strong hydrogen bonds with the cellulose fibers, which helps it stick to the fabric through use and washing.16Surface and Coatings Technology. One-step construction of a phosphazene-based hybrid coating for flame-retardant, antimicrobial, and hydrophobic viscose fabric These kinds of multi-property finishes could open up viscose nonwovens for applications like protective clothing, outdoor agricultural covers, or upholstery where flammability and water resistance matter.
Recycling and Closing the Loop
Viscose nonwovens present an interesting recycling challenge. Because the fibers are already regenerated cellulose, they can theoretically be dissolved again and re-spun into new fibers. Chemical recycling processes convert waste cellulosic textiles back into fibers like viscose, modal, or lyocell. One promising method uses a hydrated zinc chloride solution to break down post-consumer cotton or viscose waste into pulp that can be processed into new viscose staple fiber.17Green Chemical Technology. Recycling of Post-Consumer Cotton Waste
In practice, most viscose nonwoven products are single-use items like wipes and medical dressings. They are contaminated with lotions, cleaning chemicals, body fluids, or soil by the time they are discarded, which makes collection and recycling economically difficult at scale. The more realistic environmental benefit of viscose nonwovens, at least for now, is that they biodegrade when they reach landfills, compost piles, or natural environments, rather than persisting for decades the way synthetic nonwovens do. The chemical recycling route is technically viable and increasingly refined, but it requires clean, sorted waste streams that the current disposal infrastructure for single-use nonwoven products does not typically provide.
How Viscose Nonwovens Compare to Synthetic Alternatives
The choice between viscose and synthetic nonwovens almost always comes down to a few key trade-offs. Viscose absorbs more, feels softer, and biodegrades. Polypropylene and polyester are stronger when wet, cheaper to produce, and more dimensionally stable. For any product that needs to hold and deliver liquid, viscose is the default choice. For products that need to act as a barrier or maintain structural integrity when soaked, synthetics have the edge.
Blending the two is common. A viscose/polypropylene nonwoven captures much of viscose’s absorbency while gaining the synthetic component’s mechanical stability. The ratio matters: as viscose content rises, the fabric absorbs more water and wicks it higher, but it also becomes more susceptible to weakening when wet.18Journal of Polymer Science Part B: Polymer Physics. Multipurpose nonwoven viscose/polypropylene fabrics: Effect of fabric characteristics on sorption and dielectric properties Product designers choose the blend ratio based on the end use. A facial wipe that needs to feel luxurious might be 80% viscose. An industrial cleaning cloth that needs to survive heavy scrubbing might be closer to 50/50.
One underappreciated factor in this comparison is electrical behavior. Viscose nonwovens pick up and store electrical charge differently than synthetic ones, and this property changes with humidity and moisture content. In industrial settings where static discharge is a concern, the dielectric properties of a nonwoven fabric can matter as much as its mechanical ones. Blended fabrics allow manufacturers to tune these characteristics for specific environments, from cleanroom wipes that must not spark to automotive interior linings that need to resist dust attraction.
Viscose Nonwovens in Wound Care
The medical uses of viscose nonwoven deserve a closer look because they illustrate how the material’s basic properties translate into clinical performance. A good wound dressing needs to absorb exudate (the fluid that seeps from healing tissue), maintain a moist environment at the wound surface, allow some air exchange, and ideally resist bacterial colonization. Plain viscose nonwoven handles the first three requirements well: it pulls fluid away from the wound, stays in gentle contact with the skin, and its porous structure allows gas exchange.
The antibacterial requirement has driven much of the research into treated viscose dressings. Silver nanoparticles are one of the most studied additions, and when combined with chitosan and a polymer binder on a viscose nonwoven substrate, they produce dressings that actively fight infection while the viscose base does the moisture management work.19Carbohydrate Polymers. Wound dressing based on nonwoven viscose fabrics The spunlaced structure of the nonwoven also matters here: the way fibers are entangled by water jets creates a fabric that conforms to body contours without stiff edges, which reduces irritation around a wound site.
For wound care manufacturers, viscose nonwoven is attractive partly because of its versatility as a platform. The same base fabric can be loaded with different active agents depending on the clinical target. A burn dressing might carry aloe and silver. A surgical drape might be treated for fluid repellency on one side while remaining absorbent on the other. This adaptability, combined with the low cost of viscose fiber and the speed of spunlace production lines, keeps viscose nonwoven at the center of disposable medical textile design.
