酸性染料固色剂TF-506S的合成及性能研究

Study on the synthesis and the properties of acid dyes fixing agent TF-506S

以磺化双酚A、萘酚磺酸、甲醛为原料,合成了一种酸性染料固色剂TF-506S.讨论了m(磺化双酚A)∶m(萘酚磺酸)∶m(甲醛)、反应温度、反应时间、pH值等对该固色剂用于锦纶织物酸性染料染色产品固色效果的影响,得到了较佳的合成工艺:m(磺化双酚A)∶m(萘酚磺酸)∶m(甲醛)=2.0∶1∶0.7,100℃反应5.5 h,pH值3.3.将TF-506S应用于7.8t锦纶双面布染色,与常用的几种酸性染料固色剂进行对比,结果表明:TF-506S使用方便,无需调酸,能使酸性染料的色牢度提高,且色光变化小.

A acid dye fixing agent TF-506S was synthesized using sulfonated bisphenol A,naphthol-sul-fonic acid and formaldehyde as materials.The influences of reactant mass ratio,reactive temperature,time and pH value on the fixation effect of acid dyed polyamide goods were discussed.The best synthetic method was obtained：m（sulfonated bisphenol A）∶m（naphthol-sulfonic acid）∶m（formaldehyde）=2.0∶1∶0.7,reacted at 100 ℃ for 5.5 h,pH value 3.3.In dyeing of 7.8t polyamide double face,compared with the commonly used acid dyes fixing agents,TF-506S was easy to be used without adjusting the pH value,which could make the fastness with little shade change.
