尼龙超细纤维用酸性染料和还原染料染色

Dyeing of Nylon Superfine Fibre with Acid Dyes and Vat Dyes

尼龙超细纤维可以用酸性染料和还原染料染色.酸性染料染色后要用丹宁酸和吐石酸(酒石酸氧化锑等)进行后处理,以提高水洗和摩擦牢度.如用还原染料,则应选用结构中含有至少2个羰基的还原染料.

Nylon superfine fibre can be dyed with acid dyes and vat dyes.Tannic acid and tartric acid(antimony tartrate,etc)after treatmment of the nylon superfine fibre dyed with acid dyes is performed to improve washing fastness and rubbing fastness.Vat dyes containing at least two carbonyl groups in the structure should be used if the nylon superfine fibre is dyed with vat dyes.
