dyeing retarder

Dilauryldimethylbenzylammonium chloride ( DAD - 12 ), a new dyeing retarder for acrylic fibers, was synthesized with fatty nitrile technology.

采用脂肪腈工艺路线合成新型腈纶染色缓染剂——双十二烷基二甲基氯化铵(DAD—12),其技术指标达到德国Hoechst公司八十年代末水平。

The results indicated that their retarding effect increased in order of DC_(2~12)

本文研究了两种阳离子Gem in i表面活性剂(DC2~12、DC2~16)对阳离子染料(阳离子蓝X-GRRL和亚甲基蓝)的缓染作用。

The results indicate that its leveling effect is equivalent to that of 1227 but superior to that of Peregal O; Its retarding effect is close to that of 1227 but better than Peregal O; Its migration is superior to that of 1227 or Peregal O.

研究了 β-环糊精对阳离子染料的缓染、移染及匀染作用,结果表明:其匀染性与1227相当,优于平平加O;缓染效果接近1227,优于平平加O;移染作用优于1227和平平加O。
