Abstract
The invention discloses a technology for dyeing dacron through disperse dye. The technology comprises the following flows: pretreatment, dyeing, cooling and washing, detergent rinsing and washing. The dyeing temperature is controlled within the range of 125 DEG C-130 DEG C, the dyeing is carried out within the temperature range of 125 DEG C-130 DEG C, not only is the levelling property good and is the color yield high, but also the pH value of the dye bath is controlled within a weak acid range of 5-6, the majority of disperse dyes are relatively stable, and therefore, the color is bright. The dye can be evenly adsorbed by dacron under the strict control on the temperature rise rate.
Description
Technical field
The invention belongs to dyeing, be specifically related to a kind of disperse dyeing of polyester technique.
Background technology
Terylene close structure, degree of crystallinity and the degree of orientation are all very high, and dyestuff scattering and permeating is in the fibre very difficult, therefore adopts the common staining method dyeed below boiling point or boiling point, and dyeing rate is very slow, and Dry Sack is very light, can not obtain satisfied Color.In order to improve dyeing rate and upper dye amount, temperature must be improved during dyeing or take other measure.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, a kind of disperse dyeing of polyester technique is provided, easy to operate, even dyeing.
Disperse dyeing of polyester technique provided by the invention, technological process is as follows:
1. fabric uses acetum impregnation process 15min at normal temperatures;
2. add dispersant and be warming up to 60 degree then by dyestuff cold water furnishing pulpous state and molten open add among, in 30 to 60min, be warming up to 130 degree, in 130 degree insulation dyeing 30-60min;
3. cooling washing: temperature-fall period is first cooled to 80 degree with the speed of cooling per minute 1 degree, then is cooled to 60 degree with the speed of cooling per minute 3 degree, uses clean water after finally accelerating to be down to normal temperature;
4. detergent washing: wash 15min in containing the washing bath of washing agent 1g/L under 80 degree;
5. wash: use clean water fabric.
Disperse dyeing of polyester technique provided by the invention, its beneficial effect is, dyeing temperature controls at 125 degree within the scope of 130 degree, dye at this temperature, not only good level-dyeing property tinctorial yield pH value that is high but also dye bath controls within the scope of the weak acid of 5-6, thumping majority DISPERSE DYES quite stable, therefore Dry Sack is very bright-coloured.Strict control programming rate makes dyestuff be adsorbed by terylene equably.
Detailed description of the invention
Below in conjunction with an embodiment, disperse dyeing of polyester technique provided by the invention is described in detail.
Embodiment
1. fabric uses acetum impregnation process 15min at normal temperatures;
2. add dispersant and be warming up to 60 degree then by dyestuff cold water furnishing pulpous state and molten open add among, in 30 to 60min, be warming up to 130 degree, in 130 degree insulation dyeing 30-60min;
3. cooling washing: temperature-fall period is first cooled to 80 degree with the speed of cooling per minute 1 degree, then is cooled to 60 degree with the speed of cooling per minute 3 degree, uses clean water after finally accelerating to be down to normal temperature;
4. detergent washing: wash 15min in containing the washing bath of washing agent 1g/L under 80 degree;
5. wash: use clean water fabric.
Claims (1)
1. a disperse dyeing of polyester technique, is characterized in that, processing step comprises:
A. fabric uses acetum impregnation process 15min at normal temperatures;
B. add dispersant and be warming up to 60 degree then by dyestuff cold water furnishing pulpous state and molten open add among, in 30 to 60min, be warming up to 130 degree, in 130 degree insulation dyeing 30-60min;
C. to lower the temperature washing: temperature-fall period is first cooled to 80 degree with the speed of cooling per minute 1 degree, then is cooled to 60 degree with the speed of cooling per minute 3 degree, use clean water after normal temperature is down in finally acceleration;
D. detergent washing: wash 15min in containing the washing bath of washing agent 1g/L under 80 degree;
E. wash: use clean water fabric.
