Embodiment 1
[0019] A method for judging the quality of collagen fibers, comprising the following steps:
[0020] Take the processed extracted collagen fibers (from the split skin of the yellow cowhide body), knead them evenly, first conduct moisture detection, and then calculate according to the results of the moisture detection, add ice water and mix the collagen fiber group Knead evenly, and the temperature of the material should not be higher than 18°C, so that the water mass content can reach 90%.
[0021] Put the collagen fiber group in a 50mL centrifuge tube and centrifuge in a high-speed centrifuge (10000rpm, 20min). Take out and measure the moisture of the upper end and the lower end, and there is no difference in the moisture content, indicating that the water is bound by the collagen fibers, and the fibers have strong water absorption.

Embodiment 2
[0024] A method for judging the quality of collagen fibers, comprising the following steps:
[0025] Take the processed extracted collagen fibers (from the split skin of the head of the yellow cowhide), knead them evenly, first conduct moisture detection, and then calculate according to the results of the moisture detection, add ice water and mix the collagen fiber group Knead evenly, and the temperature of the material should not be higher than 18°C, so that the water mass content can reach 90%.
[0026] Put the collagen fiber group in a 50mL centrifuge tube and centrifuge in a high-speed centrifuge (10000rpm, 20min). Take it out and measure the moisture of the upper and lower ends. If the moisture of the lower part is higher than that of the upper part, it means that the water absorption capacity is weak, the opening degree of the fiber bundles is not enough, or the collagen fibers are damaged during the hide treatment process, and the treatment is excessive.

Embodiment 3
[0029] A method for judging the quality of collagen fibers, comprising the following steps:
[0030] Take the processed extracted collagen fibers (from the split skin of the head of the yellow cowhide), knead them evenly, first conduct moisture detection, and then calculate according to the results of the moisture detection, add ice water and mix the collagen fiber group Knead evenly, and the temperature of the material should not be higher than 18°C, so that the water mass content can reach 90%.
[0031] Put the collagen fiber group in a 50mL centrifuge tube and centrifuge in a high-speed centrifuge (10000rpm, 20min). Take out and measure the moisture of the upper end and the lower end, and there is no difference in the moisture content, indicating that the water is bound by the collagen fibers, and the fibers have strong water absorption.
