Embodiment

[0011] The synthesis process of the degradable milk protein fiber blend fabric of the present embodiment comprises the following steps:

[0012] (1) Firstly, high-molecular-weight nano-iron oxide composite polybutylene succinate was obtained by using an effective synthesis process. The dosage of nano-iron oxide was 20‰, the molar ratio of raw materials butanediol to succinic acid was 1.15, and the catalyst was A combination of toluenesulfonic acid and an organotin compound or an organotitanium compound. The amount of toluenesulfonic acid added is 150×10-6 of the amount of butanediol, and the amount of organic metal salts added is 300×10-6 of the amount of butanediol;

[0013] (2) Then nano-iron oxide blended polyester is spun, the initial spinning stretching temperature of melt spinning is 230°C, the speed is 2000m / min, the draft ratio of one stretch is 3.5, the temperature is 130°C, and the heat setting temperature is at 100°C, the draft ratio of the second stretching is 1.1...
