Understanding Viscose: Origins and Basics

Viscose, often called rayon, is a widely used semi-synthetic fabric. It’s made from wood pulp processed with chemicals, transforming natural cellulose into a soft, versatile fiber. Many find viscose appealing due to its silk-like feel and affordability, making it popular in everything from T-shirts to dresses. Yet, as sustainability gains attention, questions about how eco-friendly viscose truly is are cropping up, especially regarding its sourcing, chemical use, and production practices.

Production Process of Viscose Fabric

The journey from wood to wardrobe for viscose involves several stages. First, wood chips—typically from fast-growing trees like bamboo, beech, or eucalyptus—are pulped and dissolved in sodium hydroxide. The resulting cellulose solution is treated with carbon disulfide, then spun into fibers. This method delivers a fabric that’s both soft and absorbent. However, the use of hazardous chemicals and high water consumption have triggered environmental concerns. Manufacturers like Ninghow Apparel, who prioritize fabric transparency, often educate partners about the available alternatives for reducing the environmental footprint of viscose production.

Key Environmental Concerns: Deforestation and Source Materials

One major concern with viscose is the source of its wood pulp. Unsustainable logging practices can lead to deforestation, threatening ecosystems and biodiversity. Certified wood, such as that from FSC-accredited forests, offers a solution, but not all viscose products use responsible sourcing. Some sustainable manufacturers now prioritize supplier transparency—but traceability in the supply chain can still be patchy.

Chemical Processing: Pollution and Worker Safety

The viscose process relies on chemicals like sodium hydroxide and carbon disulfide, both of which are toxic if mishandled. Effluent from viscose factories can pollute local waterways unless proper treatment systems are in place. Furthermore, carbon disulfide can pose severe risks to worker health, including nerve and reproductive damage. Some modern viscose plants use closed-loop systems to recover and reuse chemicals, helping to minimize environmental harm and protect workers.

Water and Energy Consumption

The traditional viscose method is water- and energy-intensive. Processing one kilogram of viscose can require hundreds of liters of water, along with significant electricity for pulping, spinning, and cleaning. In water-scarce regions, local resource stress is a real issue. Advances in technology—like closed-loop or lyocell techniques—reduce water use. Compared with conventional cotton or polyester, viscose can be less or more resource-heavy depending on production location and facility standards.

Biodegradability and Microfiber Shedding

Unlike plastic-based synthetics, viscose is biodegradable under industrial composting. In theory, it should break down faster than polyester. However, chemically finished viscose products or blends with synthetics may degrade more slowly or release microfibers into the environment. Ongoing research suggests viscose sheds fewer microplastics than polyester during washing, but responsible disposal and product design remain key for long-term sustainability.
