Rayon vs Viscose (and Crepe): A Woven Fabric Guide for US Brands

Categories Manufacturing Guides

Rayon, viscose, and crepe confuse US brands for two different reasons: one is a labeling split, and the other is not a fiber at all. We build all three into finished garments at Kizen Lab in Bandung, under FOB programs. If you are weighing these three names, these are the questions to settle first: what each name means, how the fabric behaves, and what to spec before production starts.

The short answer: viscose is rayon made by the viscose process, the most common way to make it. Crepe is a texture, not a fiber, and you can order it in polyester, viscose, silk, or wool.

Is viscose the same as rayon?

Yes, with one distinction worth knowing. Rayon is the generic US fiber name for fibers made from regenerated cellulose, and viscose is rayon made through the viscose process, which is the most common way to make it. The raw material is primarily wood pulp. The naming is regional: European labels read viscose, US labels read rayon.

The practical consequence for a US brand is that the two names are not two quotes. A mill quoting viscose and a mill quoting rayon are, in most cases, quoting the same fiber family, so compare the specs (weight, finish, grade) rather than treating the label difference as a difference in fabric. The same labeling rule drives our bamboo fabric guide: cloth regenerated from bamboo pulp also labels as rayon (or viscose) in the US, whatever the swing tag says.

How do rayon and viscose behave in a garment?

The fiber’s appeal is the drape: soft, cool, absorbent, and fluid, hanging closer to the body than a similar-weight cotton woven and feeling cooler than polyester. Weight drives that hang: the fabric GSM guide shows how the number translates to drape and opacity. That is why rayon and viscose are a common choice for dress and blouse programs in warm-weather lines. For pure warm-weather programs, the linen fabric guide for US clothing lines covers the other summer staple.

The trade-offs are real and belong in your spec from day one. Regular viscose rayon loses strength when wet, has the lowest elastic recovery of any fiber, and is dimensionally unstable in water: it shrinks and can pull out of shape. None of that makes it a bad fabric. It makes it a fabric that needs a care plan, and it makes shrinkage a pre-production question: the sampling round cuts the actual fabric, so fit gets checked on cloth that behaves like bulk production, not on a swatch that behaves differently.

What is crepe, and does it stretch?

Crepe is a texture, not a fiber. The crinkled, puckered surface comes from hard-twist yarns and the crepe weave, sometimes finished with heat or chemicals, and the texture is what gives crepe garments their movement. It is a standard choice for dresses, gowns, eveningwear, and blouses.

You can order the texture in the fiber your price point needs: polyester crepe is the most common, viscose crepe carries the drape of rayon with a surface that resists wrinkles slightly better than a plain weave, silk crepe de chine sits at the top of the range, and wool crepe has its own drape. On stretch: standard woven crepe has little to none. If a pattern needs give, that is a spec question, because stretch crepe is a distinct product with elastane added, not a default.

What should the care label say?

The care path follows the fiber grade, and this is the decision brands most often leave too late. Regular viscose rayon is dry-clean only. Higher-wet-strength grades (high-wet-modulus rayon, modal) can be machine washed. Washable viscose defaults:

  • Cold gentle wash, mild detergent
  • Hang dry; never wring
  • Low-heat iron with a press cloth

Because the care label must match the fabric actually in the garment, the grade and the care path get specified together in the tech pack, before sampling, not after the labels are printed. The fabric testing step in the FOB program is what confirms the cloth behaves the way the label promises.

Why source these fabrics in Indonesia?

Indonesia’s viscose supply chain runs through West Java: viscose staple fiber has been produced at Purwakarta, between Jakarta and Bandung, since 1982, at one of the world’s largest viscose fiber plants. For a US brand, that means the fiber source sits close to the weaving and cutting floor, and the fabric questions, grade, weight, drape, and finish, get answered close to the mill, not across an ocean. Our fabric sourcing and testing step runs against that local supply before cutting.

Rayon vs viscose: the quick answers

Is viscose the same fabric as rayon?

Yes. Viscose is rayon made by the viscose process, the most common route; rayon is the US fiber name and viscose the European label. Compare the specs, not the names.

Does crepe fabric stretch?

Standard woven crepe has little to no stretch. Stretch crepe is a separate product with elastane added, so spec which one the pattern needs.

Is crepe a fiber or a weave?

Neither exactly: crepe is a texture, produced by hard-twist yarns and the crepe weave, and it can be ordered in polyester, viscose, silk, or wool.

Does rayon shrink when washed?

Regular viscose rayon is dimensionally unstable in water and is dry-clean only; higher-wet-modulus grades and modal can be machine washed. Spec the grade and write the care label to match.

Why does viscose feel cooler than polyester?

Viscose is highly absorbent and does not trap body heat the way synthetics can, so the fabric reads cooler against the skin in warm weather. That is the property behind its drapey-dress and blouse role.

What is crepe de chine?

The silk version of crepe: light, airy, and known for a graceful drape. Viscose and polyester crepe de chine exist too, at lower price points, with the same textured surface.

What fabric should a first woven program run?

The one whose drape and care path you have specified completely. First confirm a woven belongs in the lineup with the woven vs non-woven guide, cover the weight decision in the fabric weight and drape guide, and use the tech pack checklist to spec it all.

Bring the fiber, the weight, and the finish to the quote page at MOQ 500, FOB, and the sampling round will test the fabric you meant, not the one the mill guessed.
