The synthetic fiber industry is changing its procedures to satisfy this demand as brands and yarn producers prioritize sustainable solutions more and more. Mauro Dallavalle, senior marketing manager, fibers global at US-based firm Avient, discussed these trends and Avient’s role in the transition in an interview with Fibre2Fashion.
“Sustainable solutions that can lower brand owners’ and yarn producers’ carbon footprints are generally needed. Finding solutions to meet this growing need is one of the main trend drivers in the specialised materials industry,” Dallavalle told F2F. He emphasized that one popular strategy is using more recycled materials in textiles, which reduces reliance on fossil-based resources and the carbon footprint of the sector.
In addition to recycling, Dallavalle thinks the industry should look into other ways to reduce greenhouse gas emissions, like altering the way yarns are dyed. The methods used for bath dyeing today use a lot of water and energy. Spin-dyeing or dope-dyeing, which is appropriate for extruded synthetic fibers like polyester and nylon, is a more environmentally friendly substitute.
Spin-dying, as opposed to bath-dying, incorporates color during the production of yarn, minimizing the number of steps and the amount of energy used. Additionally, this dry dyeing technique uses concentrated colorant pellets, which eliminates the need for producing waste water and water.
“As a long-time provider of colourants for the spin-dyeing method, we see it as a good dyeing alternative for textile products that do not go through frequent colour changes,” concluded Dallavalle lists technical textiles, permanent colors, and brand colors as appropriate uses.
