CELLULOSIC FIBRE DEEP DYEING PROMOTER FF

介绍了增深剂 Ｆ Ｆ 的特性和增深原理，并通过活性、直接、还原、硫化染料增深染色试验。结果表明：增深剂 Ｆ Ｆ 不仅提高了染料的上染率，增深效果显著，经济效益十分明显，而且节省染料成本１０ ％ ，降低了污水中的残留染料，减轻了环境污染，具有一定的环保意义，社会效益也很可观。

The characteristics and deep dyeing promoting mechanism of deep dyeing promoter FF were intro_duced in this paper and deep dyeing experiments with this promoter were carried out on reactive, direct, vat and sulphur dyes. The result demonstrates that promoter FF improves dye up-take and achieves significant results in deep dyeing and in economic efficiency. The cost of dyestuff is reduced by 10% and residual dyes in effluent lo_ wered, thus reducing environmental pollution. Therefore, promoter FF is an environmentally friendly product which can also achieve considerable social benefit.
