Embodiment 1
[0050] Embodiment 1: natural plant dyestuff to cellulose fiber printing and dyeing process
[0051] The process is as follows:
[0052] (1) Pretreatment: firstly, 5 g / liter a-amylase was used to catalyze the starch size of the hydrolyzed fabric for 50 minutes, the temperature: 50°C, the pH value was 4, the bath ratio: 1:10, and the cotton fabric was desized. Then use catalase to bleach the fabric, temperature: 20°C, pH value 4, catalase dosage is 4 ml / liter, time 15 minutes, then use catalase 1 g / liter, time 15 minutes, normal temperature, Remove residual hydrogen peroxide from fabrics.
[0053] (2) Soaping: Prepare clean water with a bath ratio of 1:10, put it into the cotton fabric and add 0.5g / liter of neutral soaping agent at the same time, raise the temperature to 60°C, keep it warm for 20min, and drain.
[0054] (3) Pre-mordanting: prepare clean water, water hardness <50, bath ratio 1:10, put in cotton fabric and mordant Modi Mahati 2g / liter, start to heat up the morda...
Embodiment 2
[0060] Embodiment 2: natural plant dyestuff to cellulose fiber printing and dyeing process
[0061] The process is as follows:
[0062] (1) Pretreatment: firstly, 6g / liter a-amylase is used to catalyze the starch size of the hydrolyzed fabric for 55 minutes, the temperature: 60°C, the pH value is 5, the bath ratio: 1:10, and the cotton fabric is desized. Then use catalase to bleach the fabric, temperature: 25°C, pH value 5, catalase dosage is 5 ml / liter, time 20 minutes, then use catalase 1.5 g / liter, time 15 minutes, normal temperature, Remove residual hydrogen peroxide from fabrics.
[0063] (2) Soaping: Prepare clean water with a bath ratio of 1:10, put it into the cotton fabric and add 1g / liter of neutral soaping agent at the same time, raise the temperature to 70°C, keep it warm for 25min, and drain.
[0064] (3) Pre-mordanting: prepare clean water, water hardness <50, bath ratio 1:10, put cotton fabric and mordant Modi Mahati 3g / liter, start to heat up the mordant solu...
Embodiment 3
[0070] Embodiment 3: natural plant dyestuff to cellulose fiber printing and dyeing process
[0071] The process is as follows:
[0072] (1) Pretreatment: firstly, 7g / liter a-amylase was used to catalyze the starch slurry of the hydrolyzed fabric for 60 minutes, the temperature: 70°C, the pH value was 7, the liquor ratio: 1:20, and the cotton fabric was desized, Then use catalase to bleach the fabric, temperature: 30°C, pH value 7, catalase dosage is 6 ml / liter, time 20 minutes, then use catalase 2 grams / liter, time 20 minutes, normal temperature, Remove residual hydrogen peroxide from fabrics.
[0073] (2) Soaping: Prepare clean water with a bath ratio of 1:20, put it into the cotton fabric and add 1.5g / liter of neutral soaping agent at the same time, raise the temperature to 80°C, keep it warm for 30min, and drain.
[0074](3) Pre-mordanting: prepare clean water, water hardness <50, bath ratio 1:20, put in cotton fabric and mordant Modi Mahati 5g / liter, start to heat up the...
