Attempts were made to modify polypropylene fibers by melt blending with polyethylene terephthalate in order to enhance the dyeability of the resultant fiber. Five blends of polypropylene/polyethylene terephthalate/compatibilizer were prepared and subsequently spun into fibers. Three disperse dyes were used to dye such modified fibers at boiling and 130 °C. The dyeing performance of the blend fibers, as well as the morphological, chemical, thermal, and mechanical properties, of the corresponding blends was characterized by means of spectrophotometry, polarized optical microscopy, scanning electron microscopy (SEM), FT-IR spectroscopy, differential scanning calorimetry (DSC), and tensile testing.
为了提高所得纤维的可染性，人们尝试通过将聚丙烯纤维与聚对苯二甲酸乙二酯进行熔融共混来对其进行改性。制备了五种聚丙烯/聚对苯二甲酸乙二酯/增容剂共混物，随后将其纺成纤维。使用三种分散染料在沸腾温度和130℃下对这种改性纤维进行染色。通过分光光度法、偏光显微镜、扫描电子显微镜（SEM）、傅里叶变换红外光谱（FT-IR）、差示扫描量热法（DSC）和拉伸试验对共混纤维的染色性能以及相应共混物的形态、化学、热和机械性能进行了表征。
