Archroma and Lameirinho Partner on Single-Step Dyeing Process
New InOneGO process combines coloration, fixation and softening in one pad-dry application step
Archroma and Portugal-based home textiles manufacturer Lameirinho are collaborating to introduce InOneGO by Archroma, a single-step dyeing process, into commercial production. Lameirinho’s first bedlinen collection produced using InOneGO is now available worldwide.
The process is designed to combine coloration, fixation and softening into a single pad-dry application step, while enabling a range of shades and textile effects.
InOneGO Enables Multiple Textile Effects
Developed for woven cellulosic textiles, InOneGO can be used for denim, fashion wear and home textiles. The process is compatible with Archroma’s sulfur dyestuffs, including the DIRESUL® RDT range of pre-reduced low-sulfur liquid dyes and the biomass-based EarthColors® and FiberColors® sulfur dyes.
According to Lameirinho, the process can produce effects including authentic indigo denim looks, wash-down effects and vintage-inspired finishes for home textiles.
“This new InOneGO by Archroma process enables Lameirinho to achieve a wide range of shades and effects – including authentic indigo denim looks, wash-down effects and vintage-inspired finishes – bringing depth, character and a contemporary aesthetic to home textiles. At the same time, it simplifies the dyeing process by reducing the number of processing steps, and decreases resource consumption,” said Jorge Leitão, Innovation and Development Manager at Lameirinho.
Process Designed to Reduce Resource Consumption
Archroma said InOneGO provides an alternative approach to producing wash-down effects by reducing the number of conventional processing stages. The technology is designed to support a range of earthy tones, deep blues and dark blacks while maintaining fastness and shade range.
“Achieving the washed-down look conventionally requires multiple washes, with extra water and energy needed at each stage. InOneGO is a genuine structural innovation. It delivers that same distressed character in a single step, with no trade-off in fastness – even after wash-down,” Julio Perales, Technical & Product Segment Manager, Archroma Textile Effects, said.
Impact Assessment Shows Lower Resource Use
Archroma’s ONE WAY Impact Calculator was used to assess the environmental impact of InOneGO with DIRESUL® RDT for woven fabrics, including denim and jacquard.
The assessment included an easy wash-down effect finish and compared the process with conventional cold pad-batch reactive dyeing with pigment top-dye finish.
The results indicated reductions of up to:
- 81% less process time
- 97% less water consumption
- 65% less energy consumption
- 75% less CO₂ emissions
Commercial Production Begins with Lameirinho
The InOneGO process operates on Stenter and Thermosol lines, while performance finishes can be applied in a second step.
Lameirinho’s first InOneGO bedlinen collection is now available worldwide, marking the introduction of the process into commercial production for the Portuguese home textiles manufacturer.
