| titleOfInvention | A method of dyeing a substrate comprising elastomeric fibre and non-elastomeric fibre, and a dyed subtrate comprising these fibres |
| abstract | The present invention relates to a method of dyeing a substrate comprising (i) elastomeric fibre containing at least 30 wt.% of a first polymer having a glass transition temperature T of less than 60°C and (ii) non-elastomeric companion fibre containing more than 50 wt.% of a second polymer, said second polymer being polymer having no glass transition temperature or polymer having a glass transition temperature T 2 that is at least 20°C higher than T 1 , said method comprising: a)contacting the substrate with a dyeing medium to produce a pre-dyed substrate comprising 10 dyed elastomeric fibre and dyed companion fibre; b) contacting the pre-dyed substrate with an extraction medium at a temperature T e and a pressure P e , to produce a high fastness dyed substrate, said extraction medium comprising at least 50 wt.% of supercritical or liquefied carbon dioxide; wherein T e exceeds T g1 ,extraction and wherein T e is less than T g2 ,extraction in case the companion 1 fibre contains more than 50 wt.% of polymers having a glass transition temperature T 2 ; T g1 ,extraction representing the glass transition temperature of the first polymer in carbon dioxide at pressure P e ; and T g2 , extraction representing the glass transition temperature of the second polymer in carbon dioxide at pressure P e . 20 The present method enables the production of dyed substrates containing elastomeric fibre as well as non-elastomeric companion fibre that exhibit extremely high colour fastness because the dye is almost exclusively contained in the companion fibres. The present invention also provides a dyed substrate that can be obtained by the 2 aforementioned dyeing method. |
