PARIS – Spanish filament and yarn supplier Nylstar used last weeek’s Premiere Vision to showcase its ‘Ecodye’ polyamide fibre collection for autumn 2016 – winter 2017. The dope-dyed yarns use a ‘one-step’ collaboration process, where colouring is added to the polymer during its production – contrasting traditional techniques of dyeing fibres separately. Tommy Lee reports from Paris.
