Colour fastness
Colour durability is assessed against washing, light, rubbing and perspiration.
OUR TECHNOLOGY
Natural dyeing innovation
HUNA DYEING™
HUNA DYEING™ retains the environmental potential of natural dyeing while advancing quality, reproducibility, productivity and material compatibility for commercial fashion products.
Dyeing performance for contemporary fashion
Quality is managed for both the finished product and repeat production.
Levelness and reproducibility
Shade consistency is managed across each fabric and between production lots.
Production readiness
Material, process and quality management are connected for repeat-order production.
Process engineering for natural resources
A scientific approach tailored to dyestuff constituents and fibre characteristics.
01
Material characterisation
Constituents and marker compounds are analysed to characterise natural colour sources.
02
Material-specific process design
Dyeing conditions are designed around the interaction between dyestuff, fibre and target shade.
03
Colour and quality verification
Fastness and colour-comparison results are fed into production control.
Broader applications for natural dyeing
Applications extend from cotton and regenerated cellulosics to polyester, nylon, polyethylene and leather. The focus is dyeing performance across materials, not only a change of dyestuff.
Natural fibres
Cotton · Organic Cotton
Natural dyeing for cotton, organic cotton and other natural fibres, with attention to their characteristic texture, construction and blend.
Regenerated fibres
TENCEL™ · Modal · Rayon
Colour and hand feel developed for cellulosic regenerated fibres, including TENCEL™ lyocell, modal and rayon, with each material’s characteristics in mind.
Recycled fibres
rPET · rNylon · Recycled Cotton
Expanding into recycled fibres: rPET from used PET bottles, PA6 rNylon from discarded fishing nets, and recycled cotton recovered from textile waste.
Synthetic fibres
Polyester · Nylon
Applications in polyester, nylon and a range of blends, with colours and dyeing performance reviewed for the intended product and use.
Specialist materials
Leather · Polyethylene
Exploring natural dyeing for leather, mushroom and cactus leather alternatives, and difficult-to-dye materials such as cool-touch polyethylene.
Further textile & fashion materials
More possibilities
Looking beyond established fibre categories to explore dyeing possibilities for textile and fashion materials with new compositions and constructions.
Quality evidence and production control
More than 200 quality test references have been accumulated through testing institutions and in-house evaluation. Published results are organised by material and colour.
