What is viscose and how is it made?

What is viscose fiber in luxury rug manufacturing?

Viscose represents a semi-synthetic textile fiber manufactured from regenerated wood cellulose. Sarelli Textiles utilizes viscose in rug production to replicate the light-reflecting properties of natural silk, achieving a high-luster finish suitable for low-traffic residential spaces.

Viscose fibers absorb up to 13 percent of their weight in moisture, making viscose highly susceptible to liquid damage. Sarelli Textiles recommends placing 100 percent viscose rugs in dry environments with relative humidity below 60 percent. A standard pure viscose rug from Sarelli weighs approximately 3,500 grams per square meter (GSM) and features a pile height of 8 to 10 millimeters. Clients selecting Rug Materials often choose viscose for bedroom settings where foot traffic remains minimal and the visual sheen provides maximum impact.

How does the viscose manufacturing process work?

The viscose manufacturing process transforms solid wood pulp into a viscous liquid solution before extruding the liquid into solid threads. Manufacturers treat purified cellulose with sodium hydroxide and carbon disulfide to create the final spinnable cellulose xanthate solution.

The production cycle requires approximately 14 to 16 hours from pulp extraction to final yarn spinning. Workers steep the wood pulp in a 17.5 percent sodium hydroxide solution at 20 degrees Celsius for two hours. The chemical reaction produces alkali cellulose. The factory then presses the alkali cellulose to remove excess liquid and shreds the material into fine crumbs. The crumbs age for two to three days before workers add carbon disulfide. The addition of carbon disulfide creates cellulose xanthate. The factory dissolves the cellulose xanthate in a dilute sodium hydroxide bath to form the thick liquid known as viscose.

Mechanical spinnerets extrude the viscose liquid into an acid bath containing sulfuric acid, sodium sulfate, and zinc sulfate. The acid bath immediately converts the liquid streams into solid cellulose filaments. Sarelli Textiles uses the resulting filaments to produce yarn for Hand-Tufted Production, spinning the fibers into multiple ply weights depending on the specific rug design.

Viscose performance metrics and material blending conditions

Pure viscose lacks the structural memory of natural wool and crushes permanently under heavy furniture. Sarelli Textiles frequently blends viscose with New Zealand wool to increase the abrasion resistance and structural integrity of custom floor coverings.

A typical blended rug contains 70 percent wool and 30 percent viscose. The 70/30 wool-viscose blend withstands up to 15,000 Martindale abrasion cycles, whereas a 100 percent viscose rug typically fails after 5,000 cycles. Sarelli Textiles applies the blending technique during Bespoke Customization projects to balance durability with aesthetic sheen. The wool provides a resilient base structure, while the viscose accents reflect light to highlight specific design motifs.

Material Composition Average Weight (GSM) Martindale Abrasion Limit Recommended Traffic Level
100% Viscose 3,500 GSM 5,000 cycles Low traffic (Bedrooms)
70% Wool / 30% Viscose 4,200 GSM 15,000 cycles Medium traffic (Living Rooms)
