wiskoza

Wiskoza, known in English as viscose, is a semi-synthetic cellulose fiber derived from natural cellulose. It is produced through the viscose process and is widely used in the textile industry for its soft feel, good drape and ability to take up dyes well.

The production involves converting cellulose pulp into a viscose solution that can be spun into fibers. Historically, cellulose is treated with caustic soda and carbon disulfide to form viscose xanthate, which is dissolved and forced through a spinneret into an acid coagulation bath where cellulose is regenerated as fibers. The resulting fibers can be manufactured in various finishes and textures, including plain, crepe, and chiffon, and are often blended with other fibers to balance performance and cost.

Properties and applications: wiskoza fibers are soft, breathable and highly absorbent, with good dyeability and a smooth hand. They have good drape and are comfortable in warm weather, but they can weaken when wet and may be prone to wrinkling and shrinking. Common uses include apparel such as dresses, blouses and linings, as well as home textiles, upholstery and some industrial fabrics. It is frequently used in blends with cotton, polyester or wool to combine comfort with durability.

Environmental aspects and alternatives: the viscose process has historically been chemical-intensive and associated with environmental concerns, particularly due to the use of sulfur-containing reagents. Modern practices aim to reduce emissions and improve wastewater treatment, and there is growing use of more eco-friendly cellulose fibers such as lyocell. In consumer markets, wiskoza remains common for affordable, soft fabrics, though sustainability considerations influence sourcing and labeling.
