Embodiment 1
[0029] (1) Prefabricated dye: under the protection of nitrogen, first add ε-caprolactone to fine dye, oxalic acid, and initiator, ultrasonically disperse evenly, and then pour it into the dye tank, which is protected by nitrogen gas to obtain liquid dye; fine dye It is copper sulfate; the initiator is ethylene glycol; in the preparation of the liquid dye, the mass ratio of ε-caprolactone, fine dye, oxalic acid, and initiator is 100:18:0.5:1.3;
[0030](2) Pre-dyeing: The textile fabric is preheated and dried by hot air at 106°C for 26 minutes, and then continuously pulled by the traction device through the dye tank. 3 sets of tension rollers are installed in the dye tank to make the liquid dye continuously dip into the textile cloth, and the dip-dyeing time is controlled. : 10s, obtain the woven fabric of exhaust dyeing; The material of woven fabric is the woven fabric that contains cotton fiber 80%; 3 groups of tension rollers apply tension step by step along the direction of ...
Embodiment 2
[0040] (1) Prefabricated dyes: under the protection of nitrogen, first add ε-caprolactone to fine dyes, oxalic acid, and initiators, ultrasonically disperse them evenly, and then pour them into the dye tank, which is protected by nitrogen to obtain liquid dyes; fine dyes It is copper sulfate; the initiator is ethylene glycol; in the preparation of the liquid dye, the mass ratio of ε-caprolactone, fine dye, oxalic acid, and initiator is 100:10:0.5:0.5;
[0041] (2) Pre-dyeing: preheat and dry the textile fabric with hot air at 100°C for 30 minutes, and then continuously pull it through the dye tank by the traction device, and set 3 sets of tension rollers in the dye tank, so that the liquid dye can be continuously dipped into the textile cloth, and the dipping time is controlled In 10s, the dyed textile cloth was obtained; the material of the textile cloth was woven cloth with 80% cotton fiber; 3 groups of tension rollers applied tension step by step along the pulling direction ...
Embodiment 3
[0047] (1) Prefabricated dyes: under the protection of nitrogen, first add ε-caprolactone to fine dyes, oxalic acid, and initiators, ultrasonically disperse them evenly, and then pour them into the dye tank, which is protected by nitrogen to obtain liquid dyes; fine dyes It is copper sulfate; the initiator is ethylene glycol; in the preparation of liquid dye, the mass ratio of ε-caprolactone, fine dye, oxalic acid, and initiator is 100:40:0.5:2;
[0048] (2) Pre-dyeing: The textile fabric is preheated and dried by hot air at 110°C for 20 minutes, and then continuously pulled by the traction device through the dye tank. 3 sets of tension rollers are set in the dye tank to make the liquid dye continuously dip into the textile cloth. The dipping time is controlled In 15s, obtain the woven fabric of impregnation; The material of woven fabric is the woven fabric that cotton fiber content is 80%; The tension of the first group of tension rollers is 18N, and the tension of the third ...
