Dyecoo & DuPont launch sustainable dyeing course of

2020/10 31 07:10


DuPont Biomaterials and DyeCoo, specialising within the growth of cleaner dyeing applied sciences, have introduced a patented, sustainable dyeing course of for materials constructed from polyester or recycled polyester and Sorona. This dyeing answer allows vogue designers and types to ship excessive efficiency clothes and a lesser environmental footprint.

Materials constructed from a mix of Sorona with polyester or recycled polyester might be sustainably dyed on an industrial scale with the CO2-based course of, developed and patented by DyeCoo. This course of makes use of no chemical compounds and no water, thus doesn’t trigger any wastewater and requires no wastewater therapy. The CO2 used for the method is reclaimed from present industrial processes, recycling 95 per cent of it in a closed loop system, based on a press launch by DuPont.

Brief batch cycles, environment friendly dye use, no wastewater therapy all contribute to considerably cut back working prices and the ecological footprint, making this answer extraordinarily interesting for mills, manufacturers and shoppers targeted on sustainability.

The dyeing course of applies reclaimed CO2 because the dyeing medium in a closed loop course of. Utilized in a pressurised, super-critical state, CO2 has a really excessive solvent energy, permitting the dye to dissolve simply. Due to the excessive permeability, the dyes are transported simply and deeply into fibres, creating vibrant colors. Reacting in the same strategy to this dyeing course of, polyester and Sorona fibres are completely matched within the creation of high-end vogue materials, which include superior efficiency, larger high quality and a particularly low ecological footprint.
Sorona is constructed from 37 p.c renewable plant-based elements.

This high-performance polymer affords distinctive advantages for the attire trade, minimising the impression on the setting with out sacrificing high quality and efficiency. It affords distinctive advantages, together with unbelievable softness, stretch and restoration, and inherent stain resistance with out the necessity for topical remedies. Sorona is a USDA licensed bio-based product and obtained Oeko-Tex customary 100 certification.

The usage of 100 per cent pure dyestuff offers lovely, vibrant colors to materials constructed from polyester and Sorona. The dye is distributed evenly over the material and the expertise permits for simple color correction, creating intense colors with wonderful high quality traits. Materials constructed from Sorona mixed with polyester after which making use of the CO2 dyeing expertise developed by DyeCoo, ship magnificence, sustainability and prime efficiency.

“DyeCoo may be very glad to take part on this collaboration. It highlights how two, complementary, sustainable choices can ship one answer with an impression to our trade. Cross-industrial collaborations are an essential strategy to drive change in our trade and right here our two core competencies as corporations actually strengthen one another,” Micke Magnusson, head of business, DyeCoo mentioned.

“Our collaboration with DyeCoo on this distinctive CO2 dyeing course of will make Sorona-based materials much more sustainable. We now provide a stretch answer with much less impression on the setting whereas extending the lifetime of the garment. Many attire manufacturers will profit from such sustainable options with out compromising efficiency and worth. We’re on a progressive journey to create progressive merchandise that improve efficiency whereas being environmentally accountable. This new collaboration is a good instance of how we will work collectively to create beautiful options whereas caring for our planet,” Hao Ding, enterprise supervisor, DuPont biomaterials, EMEA.
