在3.9GHz的微波频率下，通过测量透射微波强度的角度依赖性和复介电常数，研究了牛皮中间层真皮对应的牛皮纤维取向。最小透射微波强度和最大介电损耗的方向与最大机械断裂强度的方向一致，表明构成牛皮的胶原纤维应优选沿最小透射微波和最大介电损耗的方向取向。电子显微镜照片支持这一观点。胶原纤维的主链方向和取向程度在片材中的位置与位置之间变化。微波法可快速测定牛皮中胶原纤维的取向。它可以非破坏性和无接触地应用。
The fiber orientation of cow leather sheets corresponding to the corium of the middle layer in the cow skin was studied by measuring the angular dependence of transmitted microwave intensity and the complex dielectric constant at a microwave frequency of 3.9 GHz. The direction of the minimum transmitted microwave intensity and the maximum dielectric loss agrees with that of the maximum mechanical breaking strength, suggesting that the collagen fibers constituting the cow leather should be preferably oriented in the direction of minimum transmitted microwaves and the maximum dielectric loss. The electron microphotograph supported this suggestion. The main chain direction of collagen fibers and the degree of orientation varied from position to position in the sheet. The present microwave method is convenient for quick determination of the orientation of collagen fibers in the cow skin. It can be applied non-destructively and contact-freely.
