Substitution of carriers<br />
Case illustration:<br />
Polyester dyeing<br />
Concept In dyeing of fabrics containing polyester in winches and o<strong>the</strong>r atmospheric<br />
equipment, carriers are used. Carriers can chemically be characterized as<br />
organic compounds – often chlorinated – of a solvent-like nature. By dyeing<br />
in HT-jets or o<strong>the</strong>r types of HT-machines, <strong>the</strong>re is no need for carriers. In<br />
applications where carriers are still needed, <strong>the</strong> least hazardous ones should be<br />
used. For this purpose <strong>the</strong> Federation of Danish <strong>Textile</strong> and Clothing Industries<br />
has elaborated guide-lines for evaluating harmfulness of chemicals by<br />
assigning different scores <strong>to</strong> different chemicals.<br />
