    • 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.
    • (i)包含至少30重量%的玻璃化转变温度T小于60℃的第一聚合物和( ii)含有超过50重量%的第二聚合物的非弹性体伴随纤维,所述第二聚合物是不具有玻璃化转变温度的聚合物或具有至少20°的玻璃化转变温度T 2的聚合物 所述方法包括:a)使所述基材与染色介质接触以产生包含10染色的弹性体纤维和染色的伴侣纤维的预染色的基材; b)在温度T e和压力P e下使预染色的基质与萃取介质接触以产生高牢度染色的基质,所述萃取介质包含在 至少50重量%的超临界或液化二氧化碳; 其中T 超过T g1,提取并且其中T 小于T g2,则提取 伴侣1纤维含有超过50重量%的具有玻璃化转变温度T 2的聚合物; 表示在压力P e下二氧化碳中第一聚合物的玻璃化转变温度; 和T g2,提取代表压力P e下二氧化碳中第二聚合物的玻璃化转变温度。 本方法使得能够生产含有弹性体纤维的染色基材以及具有极高的色牢度的非弹性体伴生纤维,因为染料几乎全部包含在伴生纤维中。 本发明还提供了可以通过上述2种染色方法获得的染色基材。

    • A process and apparatus for treating textile materials in supercritical carbon dioxide is disclosed. The apparatus in Figure 2 includes a preparation vessel (34) in fluid communication with a treatment system comprising a vessel (50) and valves (42), (43) and (44) for reversibly isolating the treatment vessel from preparation vessel (50). The process steps include first providing a preparation vessel in fluid communication with a treatment system. A textile is loaded into vessel (50) and the textile treatment material is loaded into vessel (34) where it is mixed with supercritical carbon dioxide. The material, preferably a dye, which has been dissolved or suspended in the carbon dioxide, is introduced into treatment vessel (50) and the textile is treated therewith.
