Abstract

Although isotactic polypropylene gives an excellent fiber having high tenacity, abrasion resistance and chemical stability, it has not been widely used as a fabric for chlothing because of its poor dyeability. A number of methods for improvement of its dyeability have been proposed, but they were too complicated and/or gave damage its original excellent properties of polypropylene. We now wish to report the synthesis of a new reactive dye for polypropylene fiber by means of carbenic process. A reactive dye was synthesized from azo disperse dye having an aldehyde group and tosylhydrazine. By using this synthesized reactive dye, polypropylene fiber was dyed to thick and fast color.

폴리프로필렌纖維는 他纖維에 比하여 機械的, 化學的性質이 매우 優秀하나 難染性 때문에 衣料用으로는 別로 쓰여지지 않고 있다. 폴리프로필렌의 染色性을 向上시키기 爲한 많은 硏究와 特許가 나와있으나 이들 大部分은 纖維의 개질등에 의한 방법으로서, 纖維에 직접, 견고한 染色을 할 수 있는 染料의 硏究는 거의 없다. 著者들은 카르벤을 生成시키므로써 他 纖維에는 勿論 폴리프로필렌纖維에 直接 染色될 수 있는 새로운형의 反應性染料를 合成하였다. 卽 알데히드基를 가지는 分散染料와 토실히드라진으로부터 合成한 새로운 反應性染料로서 폴리프로필렌을 染色한 結果, 濃色의 堅固한 染色物을 얻을 수 있었다.
