DYEING IN SUPERCRITICAL CARBON DIOXIDE

Öz

Water consumption and exhaustion in dyeing textile materials in conventional methods IS an important environmental problem. Increasing consideration of ecologic consequences of industrial processes as well as legislation enforcing the avoidance of environmental problems have caused a reorientation of thinking and promoted projects for replacement of conventional technologies. One of these new technologies is dyeing in supercritical fluids. During this dyeing process no water is used, therefore there is no waste water problem. The necessary energy consumption in this process is relatively lower than is needed to heat water in conventional methods of dyeing. Due to unnecessary of drying process, it helps to save both energy and time.

Tekstil materyallerinin klasikyontemlere gore boyanmasmda su kuIlal1lml ve bunun sonucunda olu~an atlksu, ,eYre aylsmdan onemli bir sorundur. <;:evresel sorunlan onlemek i<;in kanuni yaptmmlann ohnasl, endilstriyel proseslerin ekolojik olarak uygulanmasmdaki ge li~meler, ara~tmnac"an geleneksel telmolojilerin yerine yeni uygulamal ar dil~ilnmesine ve ara~tmnasma neden olmu~tur. Bu yeni teknolojilerden bir tanesi de siiperkritik akl~kan ortammdaki boyamadlr. Bu ortamda boyama i~lemi slrasmda su kuIlamlmadlgl i,in, atlksu sonmu yoktur.

Kurutma i~lemine gerek olmadlgl i,in hem enerjiden, hem de zamandan tasarruf saglamr.
