Technical field
The present invention relates to technical field of dye, and in particular to a kind of disperse dye composition for triacetate.
Background technology
Disperse dyes are the water-soluble relatively low nonionic dyes of a class, and the dyeing of acetate fiber, referred to as vinegar are used for earliest
Fine dyestuff.Cellulose acetate dye is then divided into two vinegar fibre and triacetate.Two vinegar fibre is applicable under cryogenic, and heat endurance is poor.And three
Vinegar fibre can be dyed under the high temperature conditions, and heat endurance is good.Cellulose acetate dye is very sensitive to temperature, when dyeing temperature
When degree is uneven or high, then it can cause bad outward appearance or dyeing defect.Current cellulose acetate dye is commercially extensively by remarks, general point
Dissipate dyestuff to use on vinegar fibre, can only select to carry out the dyeing under cryogenic conditions on two vinegar fibre, and triacetate then can be in high temperature bar
Dyed under part, but the High Temperature Disperse dyestuff that can apply to triacetate in the market then there's almost no.So with regard to mesh
Before for research and develop the disperse dyes that a kind of triacetate dyestuff can be used under the high temperature conditions, being that dyeing is highly desirable sees
's.
