四川黄羊皮组织结构的研究

Study on the Histological Structure of Yellow Goat Skins

对四川地区黄羊皮组织结构进行了研究,研究结果表明:黄羊皮粒面细致,乳头层和网状层的厚度比例适当,部位差小,抗张强度较高,是类似四川铜羊的优质原料皮。黄羊皮的部位差主要表现在颈、腹之间的厚度差别上,颈部厚,腹部薄。脂腺较发达,腺体有些呈环状包围毛表,但真皮层中几乎没有游离脂肪细胞存在。黄羊皮汗腺较发达,分泌部粗大的弯管与毛囊底部处于同一水平面上,削弱了乳网两层的联系,同时又有许多平卧状的毛根,这是黄羊皮易松面的组织学原因。针对黄羊皮的组织结构特点,提出了在制革生产中需相应采取的技术措施。

The characteristics of histological structure of yellow goat skins had been studied. The results showed that the grain of the goat skin was smooth.The location difference was low and the teusile strength of the goat was high.So the quality of the skin was high. According to observation, the thickest was neck, the thinnest was belly and butt was between the two. The sebaceous glands were developed. And there were few nomadic fat cells in the papillary layer and reticular layer. The sweat glands in the skin were developed, the numerous sweet glands most of which were near the bottoms of the hair follicles,weakened the link of grain layer and reticular layer and some hair roots which lay horizontally.
