Fossil-feedstock substitution
Biomass colourants provide an alternative to petrochemical synthetic dyestuffs.
A WHOLE-PROCESS VIEW
From dyestuff to finished fabric
A lower-impact process
Natural colour sources, lower-temperature shortened processes and minimised synthetic additives bring the environmental potential of natural dyeing into production.
A connected approach to materials and production
Environmental improvement is built into each stage, from colour sources to the finished fabric.

DYESTUFF
Petrochemical synthetic dyes
Biomass colourants from natural resources and plant by-products
PROCESS
High-temperature heating and repeated treatment
Dyeing at approximately 70°C with fewer process steps
ADDITIVES
Chemical inputs for colour and quality
Minimised synthetic additives and controlled residues
Natural resources and by-product use
Peels, petals, roots and leaves provide colour sources. Plant resources and processing by-products create value in dyeing and reduce reliance on fossil-based feedstocks.
Resource utilisation
Processing by-products and natural colour resources are used in dyeing.
Traceability and constituent analysis
Origin and constituent data are connected with verification of the finished dyed fabric.
Lower-temperature shorter processing
Dyeing at approximately 70°C and shorter processing reduce thermal energy demand. Energy, water and additive inputs are managed alongside material-specific quality.
01
Lower energy demand
Reduced heating and holding requirements support lower process emissions.
02
Fewer process steps
More efficient treatment and washing steps reduce resource and wastewater burdens.
03
Minimised synthetic additives
Fewer chemical inputs support control of wastewater and fabric residues.
Residual-substance management
Improvements extend from factory outputs to the fabric in contact with skin. Finished-fabric pH and residual substances are tested against requirements for baby products.
OEKO-TEX®STANDARD 100
Class 1
Certified to the baby-product class
TESTED FOR HARMFUL SUBSTANCES
Residual-substance control for skin-contact fabrics
Finished fabrics are tested against strict harmful-substance requirements for baby products. Formaldehyde, heavy metals, organotin compounds and pH are assessed and documented by material.
Measurement-led sustainability management
LCA, wastewater analysis and finished-fabric testing support environmental performance management, with quantitative indicators and sustainability reporting used to track improvement.
