What is it?
Devoré is a fibre-removal process for blended fabrics. A printed paste is heat activated to remove one fibre, leaving areas of transparency, texture, and contrast within the cloth. Commonly used on cellulose/protein or cellulose/synthetic blends, such as silk/viscose velvet or polyester/cotton.
Why does it matter?
Devoré creates patterns through the selective removal of fibre, rather than by adding colour or surface print. The effect is built into the cloth, producing a distinctive relationship between opaque and transparent areas. It is valued for:
- transparent and opaque pattern effects, commonly for use in fashion
- changes in handle, weight, and structure
- understanding of fibre behaviour and different dye chemistries to create two tones
Why is it at risk?
Traditional Devoré relies on chemically intensive systems that can present risks for users, studios, and educational settings. It requires specialist knowledge of fibre blends, paste formulation, heat activation, washing, and safe disposal. Key risks include:
- hazardous chemical paste systems
- risk of skin, eye, and respiratory exposure
- heat activation and fume concerns
- wastewater and chemical disposal issues
- restricted use in educational settings under COSHH guidance
- reliance on compatible fibre blends, which are expensive
- need for specialist technical knowledge of dyesm, access to chemicals and mixing of paste
Result: reduced accessibility, declining teaching, and loss of practical process knowledge.
Future Use / Studio Decisions
Devoré remains materially valuable, but should be used selectively and with clear justification. Its future depends on reducing hazard while retaining the process’s defining qualities of fibre removal, transparency, and structural contrast. In the studio:
- check that the fabric blend is suitable before starting
- mix only what is needed to minimise waste
- explore lower-toxicity Devoré paste formulations and reduced-hazard ingredients
- test alternative bases, such as polyester lamé with Indalca and soda ash, where steaming can dissolve the lamé layer to create positive and negative effects
- consider digital, laser, cutwork, layering, or surface contrast methods where a Devoré-like effect is sufficient
- apply paste evenly and avoid over-saturation
- use appropriate PPE, ventilation, and safe handling procedures
- follow COSHH guidance and local studio protocols
- steam and wash out thoroughly after application
- document fibre blend, recipe, timing, heat, and results.
Future Position
☐ Preserve ☑ Adapt ☐ Transform ☐ Simulate ☐ Retire Devoré remains viable through adaptation: changes in formulation, scale, management, teaching, and safe handling are needed for it to continue responsibly within contemporary practice.

Is true fibre removal essential, or could another process create a suitable transparent, layered, or textured effect?
