What viscose brings to a rug, and what it costs
Viscose is a regenerated cellulose fibre made from wood or bamboo pulp. It takes dye brightly and has a high sheen, so a viscose rug can look like silk at a much lower price. In Indian export production it is usually hand-tufted or hand-loomed, sometimes hand-knotted, and often blended with wool to add body.
The same fibre has weaknesses that show up after the sale:
- Wet strength. Viscose loses much of its strength when wet. Spills and wet cleaning can distort, flatten or tear the pile.
- Water marks. Water can leave rings and brown marks as the fibre dries.
- Crushing. The pile flattens under feet and furniture and does not spring back like wool.
- Shedding and fuzzing. Short fibres work loose, especially in the first months.
An inspection cannot change the fibre, but it can make sure the rug is what was sold, is labelled honestly and leaves the factory in good condition. For rugs where real silk is the point, see silk rugs.
What we check on viscose rugs
| Check | How it is checked | What fails |
|---|---|---|
| Fibre and label | Yarn stock and label compared with the purchase order; burn screen on a loose tuft; lab analysis for blend claims | Label says "silk", "bamboo" or "art silk" alone; blend percentages that do not match |
| Sheen consistency | Rugs from the same design laid side by side and viewed from both ends under the same light | Shiny or dull stripes where yarn from two lots was used |
| Water reaction | A drop of water on a hidden area or offcut, left to dry | Ring, brown edge or flattened patch |
| Crush recovery | Weighted block left on the pile for a set time, then recovery observed | Pile stays flattened compared with the approved sample |
| Shedding | Hand brushing or a firm palm rub over a set area; loose fibre collected | Much more fibre than the approved sample gives |
| Pile height and density | Pile gauge; rug weight per square metre on a scale | Lower height or weight than specified |
| Backing | Edge of the secondary backing lifted by hand; back checked for even coating | Backing peels, coating patchy or cracks when a corner is folded |
| Care label | Care wording compared with the buyer's artwork | Missing or recommends wet cleaning against the buyer's instruction |
Naming the fibre correctly
Mislabelled fibre is the most serious finding on a viscose rug, because the error is copied onto every product page and invoice.
- United States. Under the Textile Act, the fibre is "rayon" or "viscose". The FTC says a product may be called "bamboo" only if it is made of actual bamboo fibre; rayon made from bamboo pulp must be described as "rayon made from bamboo" or "viscose made from bamboo", and only with evidence that bamboo was the source. The FTC has fined retailers for "bamboo" labels on rayon goods.
- European Union. Regulation (EU) 1007/2011 allows only the fibre names in its Annex I. Viscose from bamboo pulp is "viscose". See EU textile labelling.
- Trade names. "Art silk", "bamboo silk" and "banana silk" may appear on factory paperwork. They must not appear as fibre content on labels, swing tags or listings.
The inspector photographs every label variant and compares it with your approved artwork, including the country of origin. See country of origin labelling.
Common viscose rug defects and how they are classed
| Defect | Class |
|---|---|
| Fibre content labelled as silk or bamboo | Critical (mislabelling) |
| Sheen stripe from mixed yarn lots | Major |
| Water mark or ring from washing | Major |
| Backing peeling at edges | Major |
| Pile weight below specification | Major |
| Crushed pile from tight packing | Minor if it recovers after unrolling; major if not |
| Loose surface fibre within the sample's level | Not a defect |
Your defect list decides the final class.
Other rules for viscose rugs
- US flammability. Like all rugs sold in the US, viscose rugs need a General Certificate of Conformity to 16 CFR 1630 (more than 6 ft long and over 24 sq ft) or 16 CFR 1631 (smaller), based on a test or a reasonable testing program; a rug made for children needs testing by a CPSC-accepted lab. A small rug that fails may only be sold with a permanent "FLAMMABLE" warning. Test the actual construction, as backing and blend change the result.
- Chemicals. REACH restrictions can apply to dyes and finishes; see azo dyes and restricted substances. Tests are done by an accredited lab.
- Labour. The US Department of Labor lists carpets from India for child and forced labour, and the EU Forced Labour Regulation applies from 14 December 2027. Ask suppliers who weaves and finishes the rugs.
Packing and your purchase order
Viscose crushes under pressure and marks if it gets damp. Rugs should be fully dry, rolled pile-out, wrapped in polythene and not stacked under heavy cartons. The inspector checks dryness, roll direction and that rolls are not bent or folded.
- Exact fibre content and label wording for each market.
- Pile height and weight per square metre, with a tolerance.
- Rules for yarn lots: one lot per design and colour, or a lot number on each rug.
- Backing type and how it is fixed.
- Care instructions, and the test for crush and shedding against an approved sample.
Viscose rugs are often hand-tufted; see hand-tufted rugs for latex and backing checks. Book a pre-shipment inspection when most rugs are packed.
