摘要/Abstract

摘要： 研究了磷酸钙盐（Ca-P）矿化对胶原纤维耐酶解性能的影响及其在酶脱毛中对皮粒面的保护作用。结果表明：磷酸钙盐包覆矿化可以在胶原纤维表面形成微米级的不溶性钙盐保护层,提高了胶原纤维的耐湿热性能和耐酶性能,为酶脱毛中皮粒面的保护提供了一种有效的方法。

关键词: 胶原纤维, 矿化, 磷酸钙盐, 酶脱毛

Abstract: The effect of calcium phosphate (Ca-P) mineralization on the protease resistance of collagen fibers and its protective effect on the hide grain surface during unhairing were studied. The result shows that: calcium phosphate coating and mineralization can form a micron-level insoluble calcium salt protective layer on the surface of collagen fibers, which improves the heat resistance and protease resistance of collagen fibers, and provides an effective method to protect the hide grain surface during unhairing.

Key words: collagen fiber, mineralization, calcium phosphate, enzymatic unhairing
