Swiss colour and speciality chemicals manufacturer Archroma has unveiled a new range of high wet-fast disperse dyes for polyester fibres in sportswear and activewear applications. 

The Foron SP-WF dyes are especially suited for the colouration of polyester fibres and microfibres, and polyester/elastane blends, in exhaustion application, the company says. 

They sit within Archroma’s Fast Sport colouration system for polyester knitted sportswear, which it says provides “the best fastness in the shortest possible time with a reduced environmental footprint.

Including both primary and ternary colour grades, the Foron SP-WF range has been developed to fulfil the high colour wet fastness and performance requirements of sportswear manufacturers and brands, Archroma says.

In addition, the range’s core ternary colour grades enable deep shades at lower dyeing temperatures on sensitive polyester/elastane fabrics without causing excessive fibre damage, saving energy resources and meeting the high fastness demand of leading brand companies.

When using Foron SP-WF dyes as part of the Fast Sport system, manufacturers have the potential to reduce their consumption of time, energy, chemical, and water, as well as CO2 emissions, the firm adds.
