Archroma, a global leader in specialty chemicals, and Lameirinho, a leading home textiles manufacturer based in Portugal, are collaborating to bring InOneGO by Archroma, a single-step dyeing process, into commercial production. Lameirinho’s first InOneGO bedlinens collection is now available worldwide.
InOneGO by Archroma is a continuous dyeing process that combines coloration, fixation and softening into a single pad-dry application step. The process is designed for woven cellulosic textiles, including denim, fashion wear and home textiles.
According to Jorge Leitão, Innovation and Development Manager at Lameirinho, the process enables the company to produce a wide range of shades and effects, including authentic indigo denim looks, wash-down effects and vintage-inspired finishes for home textiles. The process also reduces the number of dyeing steps and resource consumption.
InOneGO is compatible with Archroma’s advanced sulfur dyestuffs, including the DIRESUL® RDT range of pre-reduced low-sulfur liquid dyes, as well as the EarthColors® and FiberColors® biomass-based sulfur dyes.
The compatibility provides mills and brands with an alternative approach for producing wash-down effects across 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,” said Julio Perales, Technical & Product Segment Manager, Archroma Textile Effects.
Archroma’s ONE WAY Impact Calculator assessments indicate environmental benefits when InOneGO is used with DIRESUL® RDT for woven fabrics, including denim and jacquard. The assessments included the addition of an easy wash-down effect finishing process and were benchmarked against conventional cold pad-batch reactive dyeing with pigment top-dye finish.
The assessment results showed potential reductions of up to:
81% less process time
97% less water consumption
65% less energy consumption
75% less CO2 emissions
The InOneGO by Archroma process operates on Stenter and Thermosol lines, while performance finishes can be applied in a second step.
With Lameirinho’s first InOneGO bedlinens collection now available worldwide, the collaboration marks the commercial deployment of the single-step dyeing process in home textiles.
