The technology employed to manufacture the Eco Pur 1 flat-woven carpeting unites the intense colours of the pile yarn with the black weft yarn below. This results in brilliant colours and a vital character. Eco Pur 2, in turn, mixes the coloured pile yarn with a grey weft yarn, which is complemented by the shimmering effect of the black yarn from the woven back. This subtle combination lends the strong colours a discreet, understated appeal. Available for both structures are 47 colour variations, ranging from elegant cement grey to fashionable apple green.
