对比了纯PP纤维、PP/PS改性纤维和PP/Hy-PS(Garamite)改性纤维的上染率、染色深度K/S值、颜色饱和度C*值.试验表明,由于PP/Hy-PS(Garamite)共混纤维中纳米膨润土上带有大量羟基,从而提高了聚丙烯纤维与染料分子的亲和作用,因此在相同的染色条件下,相近规格(纤度、取向度、结晶度相近)的纤维PP/Hy-PS(Garamite)体系的上染率、染色深度K/S值、颜色饱和度C*值都较PP/PS体系有着进一步的提高.另外,耐摩擦牢度、皂洗牢度和耐汗渍牢度试验表明,PP/Hy-PS(Garamite)改性共混纤维的染色牢度都比较好,均在4级以上,完全满足服装用要求.

The properties of pure polypropylene fibers,PP/PS and PP/Hy-PS(Garamite) composite fibers,such as the dye up-take,K/S value,and color saturation C* are discussed in this paper.The experiment results indicate that large amounts of hydroxyl groups existing in the nano-garamite helped to improve the affinity between the PP/Hy-PS(Garamite)blend fiber and the dispersed dye.Thus under the same dyeing conditions,the dye up-take,K/S value and color saturation C* of PP/Hy-PS(Garamite) blend fiber with almost the same denier,orientation and crystallinity have a further enhancement than that of PP/PS blend fiber.The PP/Hy-PS(Garamite) modified blend fibers have a good color fastness to rubbing,soaping and sweating,which meet the demand of apparel industry.
