摘要(Abstract):

根据Shell公司和Dystar公司的研究,用Optidye系统从分散染料吸附与上染率、染色温度、pH值、匀染性及染色牢度等方面解析了聚对苯二甲酸丙二酯(PTT)纤维的染色性能。PTT纤维在100℃就可染到深色,在60~80℃和90~100℃有两个吸附速度较快区域;PTT纤维属易染型纤维,在最高温度染保持30~40min即可。高温型分散染料在120℃染色,常压100℃染色无需pH值调节。分散染料染色牢度(洗涤、摩擦及耐光)非常好。
According to the research by Shell Co. and Dystar Co., the disperse dyes absorption and dye-uptake, dyeing temperature, pHevalue, dye leveling and dye fastness of PTT fiber are reviewed. The fiber can be dyed deep colour at temperature of 100℃ and there were two fast absorption regions between temperature of 60~80℃ and 90~100℃. PTT fiber is a kind of easy dyeing fiber and dyeing time is 30~40 mins at the highest dyeing temperature. The high temperature dyeing with disperse dye is 120℃. The pH value adjustment is not needed with 100℃ normal temperature dyeing. The dye-fastness of PTT fiber with disperse dye is very good.
