Embodiment 1
[0056] Example 1: All cotton 20 S ×16 S / 128×60
[0057] ⑴Pretreatment method for continuous cold reactor of the present invention:
[0058] Working solution prescription: LYM-A dosage: 10g / l, LYM-B dosage: 10g / l, sodium hydroxide (100% amount) dosage: 25g / l, hydrogen peroxide (100% amount) dosage: 20g / l;
[0059] LYM-A formula: 15% oxidant, 10% acyl compound, 35% composite catalyst, 30% disodium hydrogen phosphate, 10% maleic acid-methyl acrylate polymer;
[0060] LYM-B formula: 15% emulsifier, 5% penetrant, 15% solvent, 15% alcohol ether sulfate, 1% defoamer, 49% softened water;
[0061] Process: Grey cloth→turning cloth→sewing head, hemming→singeing, one positive and one reverse, the speed is 100m / min, 1% light alkali water is used to extinguish fire, the cloth is dampened→the damp cloth is placed in the cloth dropping car for 20 minutes, and plastic film is used Sealing→85℃ wash two compartments, cold water one compartment→re-rolling car, cloth surface with water rate of 60%→paddi...

[0068] Example 2: Cotton 40 S ×40 S / 133×72
[0069] ⑴ The continuous cold reactor process of the present invention:
[0070] Working fluid prescription: LYM-A dosage: 10g / l, LYM-B dosage: 20g / l, sodium hydroxide (100% amount) dosage: 20g / l, hydrogen peroxide (100% amount) dosage: 20g / l;
[0071] LYM-A formula: 15% oxidant, 10% acyl compound, 35% composite catalyst, 30% disodium hydrogen phosphate, 10% maleic acid-methyl acrylate polymer;
[0072] LYM-B formula: 15% emulsifier, 5% penetrant, 15% solvent, 15% alcohol ether sulfate, 1% defoamer, 49% softened water;
[0073] Process: Grey cloth→turning cloth→sewing head, hemming→singeing, one positive and one reverse, the speed is 110m / min, 1% light alkali water is used to extinguish the fire, the cloth is dropped→the cloth is placed in the cloth dropping car for 20 minutes, and plastic film is used Sealing→85℃ wash two compartments, cold water one compartment→re-rolling car, cloth surface with water rate of 60%→padding working fluid, mu...
Embodiment 3
[0080] Example 3: T / C 24 S ×24 S / 100×47 (T / C65 / 35)
[0081] ⑴Continuous cold reactor process:
[0082] Working solution prescription: LYM-A1 dosage: 5g / l, LYM-B dosage: 8g / l, sodium hydroxide (100% amount) dosage: 15g / l, hydrogen peroxide (100% amount) dosage: 25g / l;
[0083] LYM-A formula: oxidizer 20%, acyl compound 10%, composite catalyst 40%, disodium hydrogen phosphate 25%, maleic acid-methyl acrylate polymer 5%;
[0084] LYM-B formula: 20% emulsifier, 5% penetrant, 15% solvent, 10% alcohol ether sulfate, 1% defoamer, 49% softened water;
[0085] Process: grey cloth→turning cloth→sewing head, hemming→singeing, one positive and one reverse, speed 120m / min, spray steam to extinguish fire, dry cloth→padding working fluid, multiple dipping and multiple rolling, high liquid supply, belt Liquid rate is 110% → double-layer track box, speed 60m / min, 35°C stacked for 90 minutes → 95°C water washing five cells → 80°C water washing one cell → 50°C warm water washing one cell → drying;
