摘要
芳纶织物具有很高的结晶度和取向度,化学结构稳定,很难上染.通过采用化学助剂使芳纶分子之间的间隙增大,降低芳纶分子间的范德华力,有利于染料进入纤维内部,提高染料的上染率.
Aramid fibers have quite high crystallinity and orientation, stable chem. structure and poor pickup, chem. auxiliaries were used to enlarge intermol, gap of the aramid fibers, lower the intermol. Vad Waals force of the aramid fibers, favor the penetration of dyes into the fibers and increase the dye pickup.
