Embodiment 1
[0017] The cold heap refining process of embodiment 1 wool silk fabric comprises the following steps:
[0018] S1: Place the wool silk fabric in the protease solution, soak it twice and roll it twice, then roll the fabric, and place the rolled fabric in a closed environment at 40°C for 24 hours;
[0019] S2: Place the wool and silk fabric obtained in S1 in the refining reaction solution, heat up to 90°C and react for 80 minutes, with a liquor ratio of 1:40;
[0020] The main components of the refining reaction solution include natural tea saponin, sodium hydrosulfite and strong acid and weak base salt pH regulator, and the pH value of the refining reaction solution is 9.3.
[0021] The protease in the protease solution is papain, and the concentration of the protease in the protease solution is 10 g / L.
[0022] The strong acid and weak base salt pH adjuster is sodium phosphate.
[0023] The concentration of natural tea saponin in the refining reaction liquid is 2g / L.
