超细分散染料的制备及影响转移印花效果的因素

研究了分散剂结构、用量和分散工艺条件等对分散染料红60分散效果的影响，分析了影响超细分散染料转移印花效果的因素。结果表明自制的分散剂PSMA对分散染料红60的分散效果较好，当其用量为分散染料重量的100%，研磨4h制备的超细染料粒径为157nm，此时超细分散染料的离心稳定性为96.3%，60℃下放置24h其粒径变化率仅为3.4%；分析影响转移印花效果因素发现超细分散染料粒径越小，相同条件下印花织物得色更均匀，K/S值越高。超细分散染料较佳的转移印花条件为印花浆粘度60 mPa·s，转移温度210℃，时间40s。

Preparation of ultrafine disperse dye and influence factors on transfer printing effect

The influences of dispersant structure, dosage and dispersing conditions on dispersing effect of disperse red 60 were studied. Influence factors on transfer printing effect were analysed. The result indicated that the PSMA applied to disperse red 60. The ultrafine disperse dye prepared with PSMA, 100 percent by weight of disperse dye, by grinding for 4 hours had 157nm diameter. Its centrifugal stability was 96.3% and particle size change rate under 60℃ for 24h was 3.4%. The transfer printing fabric with smaller particles of disperse dye had uniformer color and higher K/S value. The optimum transfer printing conditions were transfer printing at 210℃ for 40s when the viscosity of printing paste was 60 mPa·s.
