What is Viscose?
To understand whether viscose is sustainable, we first need to know what it’s made of and how it’s produced. Viscose is a man-made fabric derived from wood pulp.
Definition and Production Process
Viscose fibers are a type of semi-synthetic fiber made from wood pulp cellulose. The production process begins with wood chips being processed into a pulp through a chemical treatment, typically involving sodium hydroxide and carbon disulfide. This pulp is then dissolved and reformed into long strands called xylans, which eventually take the shape of viscose fibers.
The exact steps involved in making viscose can vary depending on the manufacturer, but most production processes follow this general outline. Notably, some manufacturers may also use recycled materials or by-products from other industries as part of their pulp mixture. This can have a positive environmental impact when done responsibly. However, critics argue that even these efforts do little to mitigate the significant carbon footprint associated with viscose production.
History of Viscose Use in Fashion
Viscose fibers were first introduced to the textile industry in the early 20th century and quickly gained popularity due to their softness, drape, and affordability. They became a staple material for high-fashion clothing, particularly evening wear and lingerie, in the 1920s and 1930s. Designers like Coco Chanel and Christian Dior frequently used viscose in their designs, further solidifying its place in fashion.
However, as with any widely adopted material, the drawbacks of viscose began to surface. Its production process involves toxic chemicals, such as carbon disulfide, which has been linked to health issues in factory workers. Additionally, the environmental impact of viscose production, including deforestation and water pollution, became increasingly evident. Despite these concerns, viscose continued to be used extensively in fashion, with many brands relying on its affordability and aesthetics.
Today, consumers are becoming more aware of the negative consequences associated with viscose production, leading some brands to explore alternative materials or sustainable viscose production methods. As a consumer, understanding the history of viscose use can help inform your purchasing decisions and encourage more eco-friendly fashion choices.
Environmental Impact of Viscose Production
Viscose production has a significant environmental footprint, primarily due to its reliance on non-renewable resources and energy-intensive manufacturing processes. We’ll take a closer look at these issues next.
