Example Embodiment
[0022] Example 1
[0023] 1) Take a small amount of water, dissolve 5% Pyrovatex CP New, 1% JFC fatty alcohol polyoxyethylene ether, and 1% hydrophilic softener in the water to prepare solution 1;
[0024] 2) Take the remaining amount of water, mix 1% industrial phosphoric acid, 0.5% formic acid, 0.5% citric acid, 50% disodium hydrogen phosphate / sodium dihydrogen phosphate buffer; then add transglutamine according to the amount of 60U / g fabric Amidase (MTG), configured as solution 2;
[0025] 3) Put solution 2 in the dyeing vat, add wool yarn containing 100% wool, the weight bath ratio of yarn to solution 2 is 1:30, and soak for 5-10 minutes at room temperature;
[0026] 4) Add solution 1 to the dye vat and mix well, continue to soak for 120 minutes at room temperature, then heat the liquid in the dye vat to 65℃ at a rate of less than 2℃ per minute, keep it warm for 30 minutes, drain the liquid, and rinse with water More than two times, dehydration and drying are enough.
