Archroma collaborates with Lameirinho to promote the commercialization of InOneGo single step dyeing process, and the bedding series has been launched globally

The single step dyeing process has entered the commercialization stage. Specialty chemical supplier Archroma and Portuguese home textile manufacturer Lameirinho are collaborating to commercialize Archroma’s InOneGo single step dyeing process. Lameirinho’s first bedding series using this process has been launched globally. This collaboration marks a structural innovation in the continuous dyeing process for cellulose fiber fabrics. According to Archroma, InOneGo is a continuous dyeing process that combines coloring, fixing, and softening into one immersion drying application step. This process is aimed at the development of cellulose woven fabrics, covering denim, fashionable clothing, and home textile products.

Process characteristics and dye matching

InOneGo can be used in conjunction with Archroma’s advanced sulfur dyes, including DIRESUL ® RDT series pre reduced low sulfur liquid dyes, as well as EarthColors ® And FiberColors ® Biomass based sulfur dyes. This combination enables factories and brands to produce washing effects with lower environmental loads, without sacrificing color fastness or tone range, and can cover earthy tones, deep blue, and deep black. Jorge Leit ã o, Innovation and Development Manager at Lameirinho, stated that this process enables Lameirinho to achieve a wide range of tones and effects, including authentic indigo denim appearance, washing effect, and vintage style finishing, bringing a sense of layering, individuality, and contemporary aesthetics to home textiles, while simplifying the dyeing process and reducing resource consumption by reducing processing steps. Julio Perales, Technical and Product Segmentation Manager of Archroma’s Textile Effects Department, pointed out that the traditional way of achieving a washed appearance requires multiple washes, each stage requiring additional water and energy. InOneGo is a true structural innovation that achieves the same distressed features in a single step, without compromising color fastness even after washing.

Environmental Impact Assessment Data

The assessment conducted using Archroma’s ONE WAY impact calculator shows that InOneGo is used in conjunction with DIRESUL on woven fabrics, including denim and jacquard fabrics.

® RDT has significant environmental benefits. The test includes adding water washable effect finishing, and comparing it with the traditional cold-rolled pile reactive dyeing and coating overlay finishing as the benchmark. The main results include: a maximum reduction of 81% in process time, a maximum reduction of 97% in water consumption, a maximum reduction of 65% in energy consumption, and a maximum reduction of 75% in CO2 emissions. The InOneGo process can be operated on setting machines and hot-melt dyeing production lines, and performance finishing can be applied in the second step.

Significance for polymer additives and fiber processing industry

From the perspective of fiber and fabric processing, InOneGo integrates dyeing and softening finishing into a single step, which means that the additive system needs to work synergistically in the same soaking drying process.

. The compatibility of soft finishing components with dyes and fixing agents, as well as their stability under continuous processing conditions, become the key to the success or failure of the process. For additive suppliers, this suggests the direction of developing functional finishing additives that match single step dyeing processes. At the same time, the adaptation requirements of this process for sulfur dye systems also reflect the increasing importance of integrated solutions for dyes and additives in the textile supply chain. In the field of denim and washed fabrics, reducing the number of washes not only reduces water and energy consumption, but also minimizes mechanical damage to fibers during multiple wet treatments. This poses new requirements for the weather stability and oxidative aging resistance of fabrics. With the growing demand for low-carbon footprint and vintage aesthetics among brands, additive solutions that can balance color fastness, hand feel, and environmental performance in single step processing will be more likely to attract the attention of spinning, weaving, and finishing enterprises.
