Archroma, a global specialty chemicals company, and Portugal-based home textiles manufacturer Lameirinho are collaborating to bring InOneGO by Archroma, a single-step dyeing process, into commercial production.
Lameirinho’s first bedlinen collection produced using the InOneGO process is now available worldwide.
Developed for woven cellulosic textiles, including denim, fashion wear and home textiles, InOneGO combines colouration, fixation and softening into a single pad-dry application step.
According to Lameirinho, the technology enables the creation of a broad range of shades and effects, including authentic indigo denim looks, wash-down effects and vintage-inspired finishes. At the same time, the process reduces the number of dyeing stages and associated resource consumption.
“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.
Compatible with Sulfur Dye Technologies
InOneGO is compatible with Archroma’s sulfur dyestuff technologies, including the DIRESUL® RDT range of pre-reduced low-sulfur liquid dyes and the EarthColors® and FiberColors® biomass-based sulfur dyes.
The combination is designed to provide mills and brands with a lower-impact approach to creating wash-down effects while maintaining fastness and a broad shade range spanning earthy tones, deep blues and dark blacks.
Reduced Processing and Resource Consumption
Archroma says conventional methods for achieving washed-down effects can require multiple washing stages, increasing water and energy consumption.
InOneGO is designed to achieve a similar distressed and washed-down character in a single process step while maintaining fastness performance.
“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,” said Julio Perales, Technical & Product Segment Manager, Archroma Textile Effects.
Environmental Impact
Impact assessments conducted using Archroma’s ONE WAY Impact Calculator indicate significant reductions when InOneGO is used 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 combined with a pigment top-dye finish.
The results indicate potential reductions of up to:
- 81% less process time
- 97% less water consumption
- 65% less energy consumption
- 75% less CO₂ emissions
Commercial Production
The InOneGO process can be operated on Stenter and Thermosol lines, while performance finishes can be applied in a subsequent step.
The commercial deployment with Lameirinho represents an application of single-step dyeing technology in home textiles, while also demonstrating its potential across broader woven cellulosic textile categories.
