摘要
用端氨基超支化合物(HBP-NH2)对选择性氧化后的亚麻织物进行接枝,再经活性染料染色.FT-IR证实氧化亚麻纤维中的醛基与HBP-NH2中的端氨基发生了接枝反应,结果表明:延长高碘酸钠氧化时间,氧化亚麻织物中醛基含量增加,越易与HBP-NH2发生接枝反应,提高无盐染色K/S值,但摩擦牢度(特别是湿摩擦牢度)逐渐降低,明度变暗,彩色度上升.
Selectively oxidized linen fabrics were grafted with amino-terminated hyperbranched polymer(HBP-NH2)and then dyed with reactive dyes.FT-IR confirmed that the aldehyde groups of the oxidized linen fibers reacted with the amino groups of HBP-NH2.The results showed that the aldehyde content of the oxidized linen fibers increased with the oxidation time of sodium periodate increasing,and subsequently increased the amount of the HBP-NH2 grafted to linen fiber.Consequently,the K/S value of salt-free dyeing was increased.The rubbing fastness(especially the wet rubbing fastness) gradually decreased,the lightness became dark and the chroma increased.
