...Polyester fibers and other fibers are highly hydrophobic, so the dye is easily distributed from the dispersing bath to the fiber and is substituted with hydroxyalkyl groups to make it easier to disperse in water. Dyeing is also done at high temperatures (130°C) or by carrier dyeing using fiber affinity auxiliaries ( o -phenylphenol, chlorobenzene, diphenyl, etc.). Disperse dyes are generally sublimable, so they are also used for thermal transfer dyes. *Some of the terminology that refers to "carrier dyeing" is listed below.

…ポリエステル繊維などは疎水性の大きい繊維であるため,染料が分散浴から繊維に分配しやすく,かつ水中に分散しやすくするためヒドロキシアルキル基などが置換している。また染色は高温(130℃)染色や繊維親和性助剤(o‐フェニルフェノール,クロロベンゼン,ジフェニルなど)を用いるキャリア染色による。分散染料は一般に昇華性をもつため,熱転写用の染料にも用いられる。… ※「キャリア染色」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
