RadiciGroup adopts sustainable dyeing technique
Jun '17
RadiciGroup has taken the initiative to promote solution dyeing of yarns that helps reduce water and energy consumption. In solution dyeing, colour is added 'upstream' in the extrusion phase, and is thus incorporated into the polymer matrix. Solution dyeing is typically utilised for dyeing large quantities of product in a standardised production process.

"Having made sustainability a strategic asset of our business, RadiciGroup is ready and fully equipped to be an 'upstream' supplier of low environmental impact products, not only for the fashion sector, but also for the automotive, furnishings and outdoor industries. Together with some of our customers in the polyester fibre area, we have projects in progress that reflect our determination to be an environmentally aware player in the production value chain: solution-dyed yarns manufactured from recycled polymer combining technical and environmental performance," said Oscar Novali, business area manager of RadiciGroup Comfort Fibres.

Life Cycle Assessment (LCA) studies conducted by Noyfil SA and Noyfil SpA, Group companies engaged in the production of polyester fibres, have shown that solution dyed yarns – both the versions obtained from virgin polymer and post-consumer recycled polymer – have a lower environmental impact than traditional yarn-dyed yarns. The solution-dyeing technique is also applied in the production of nylon, specifically Radilon polyamide 6, 6.6 and 6.10 yarn, used in the garment and technical textile sectors, dorix polyamide 6 and 6.10 staple yarn, used for automotive and technical-industrial applications, and needle felt carpeting requiring high performance in resistance and colourfastness. Solution dyeing is also suitable for polyamide 6 and 6.6 BCF yarn, yet another RadiciGroup textile carpet yarn.

"At our main production plants (Radici Yarn – polyamide yarn, RadiciFil – BCF yarn, and Noyfil – continuous polyester yarn), we have the right equipment and qualified staff for the preparation of tailored colour recipes," said Filippo Servalli, sustainability director of RadiciGroup. "We have the capability to satisfy the most diverse market demands, including the supply of small lots of product. The priority for our Group – with its vertically integrated polyamide production and extensive know-how of the chemistry upstream of all our production – is to supply reduced environmental impact products, which have an end-of-life reuse," added Servalli.
