摘要
为了提高脱色紫羊绒的染色质量,探讨了漂白工艺因素对脱色紫羊绒染色性能的影响。分别研究了原绒的色泽、白度值,助剂SLS,去铁处理等因素对羊绒上染率的影响。结果表明:随着纤维白度值的升高,脱色紫羊绒的染色平衡上染率降低;漂白对酸性染料、活性染料、媒介染料的上染率都有影响,漂白后各种染料的上染率都降低;对于媒介染料染色的上染率,残留的亚铁离子在染色过程中会与铬离子竞争与染料反应;脱色紫羊绒对染色条件更加敏感,匀染性下降,可采取低温染色工艺。
In order to improve the dyeing quality of the bleached purple cashmere, the effect of bleaching technology on the dyeing property of purple cashmere is discussed in this paper. The influence of color and luster of the original cashmere, whiteness value, auxiliary agent SIS and Fe^2＋ removal treatment on the dye uptake rate is investigated separately. The results show that the balance dyeing rate of the bleached purple cashmere decreases with increase of the fiber whiteness; bleaching has impact on weak acid, reactive and
