Abstract

The invention relates to a bleaching and dyeing technology for cotton and linen cloth. The technology comprises steps: firstly, cloth is placed in a hydrogen peroxide solution and soaked for 40min, deoxygenation is carried out for 20-30min in a rinsing solution containing deoxyenzyme, and then the cloth is subjected to presetting; dyeing employs thermal insulation dyeing, the temperature is controlled at 100-120 DEG C, the dyeing time is 30-50min, the grey cloth after rinsing and dyeing is placed in steam with a temperature of 90-100 DEG C, is subjected to steaming for 40-60min and is flushed twice and each flushing is 30-50min; then the grey cloth after water washing is soaked in a soap washing solution and washed, a hydrophilic softener is added, the grey cloth after water washing is subjected trimming, and setting is carried out on a setting machine. The rinsing and dyeing technology is advantaged by environmentally friendly raw materials, simple operation, easy control and stable dyeing performances.
