Embodiment 1
[0037] Take 3g of meta-aramid fabric, and prepare a pretreatment solution according to the bath ratio of 1:20. In the pretreatment solution, the mass percentage of N,N-dimethylacetamide is 10%, the mass percentage of sodium silicate is 0.5%, distilled water silicic acid The mass percentage of sodium is 89.5%. After the pre-treatment solution is mixed, stir at 200 rpm for 3 minutes to form a pre-treatment solution. Heat up to 40°C, add the prepared high-performance fabric, continue to heat up to 50°C, and keep it warm for 30 minutes , and then use 10% sodium hydroxide solution to adjust the pH value of the pretreatment solution containing high-performance fabrics to 7 at a rate of 2 drops / min, stir evenly, heat up to 70°C, keep warm for 60min, drain, wash, and 85°C Drying; results in a well dyed high performance fabric. The cationic red FBL is used as the dye, and the preparation of the printing paste is as follows: Disperse Scarlet GS dye 1.5%, water 77.5%, starch 8%, N,N-dime...
Embodiment 2
[0039]Take 3g of meta-aramid fabric, and prepare a pretreatment solution according to a bath ratio of 1:20. In the pretreatment solution, the mass percentage of N,N-dimethylacetamide is 30%, the mass percentage of sodium silicate is 10%, distilled water silicic acid The mass percentage of sodium is 60%. After the pre-treatment solution is mixed, stir at 200 rpm for 3 minutes to form a pre-treatment solution. Raise the temperature to 40°C, add the prepared high-performance fabric, continue to heat up to 60°C, and keep it warm for 30 minutes , and then use 10% sodium hydroxide solution to adjust the pH value of the pretreatment solution containing high-performance fabrics to 9 at a rate of 2 drops / min, stir evenly, heat up to 80°C, keep warm for 60min, drain, wash, and 85°C Drying; results in a well dyed high performance fabric. The cationic red FBL is used as the dye, and the mass ratio of the printing paste is as follows: Disperse Scarlet GS dye 3.5%, water 66%, starch 11.5%, ...
Embodiment 3
[0041] Take 3g of meta-aramid fabric, and prepare a pretreatment solution according to a bath ratio of 1:20. In the pretreatment solution, the mass percentage of N,N-dimethylacetamide is 50%, the mass percentage of sodium silicate is 20%, distilled water silicic acid The mass percentage of sodium is 30%. After the pre-treatment solution is mixed, stir at 200 rpm for 3 minutes to form a pre-treatment solution. Raise the temperature to 40°C, add the prepared high-performance fabric, continue to heat up to 70°C, and keep it warm for 30 minutes , then use 10% sodium hydroxide solution to adjust the pH value of the pretreatment solution containing high-performance fabrics to 11 at a rate of 2 drops / min, then add 5% owf dye, stir evenly, heat up to 90 ° C, keep warm for 60 min, and drain liquid, washed, and dried at 85°C to obtain a high-performance fabric that is dyed well. Disperse scarlet GS is used as the dyestuff, and the preparation of printing paste is as follows according to...
