Abstract

Leathers made from exotic skins or rare parts of animals have very good market value. The exotic leathers are usually preferred because of their patterns, naturally occurring marks and their unique structures. The objective of this study was to investigate the feasibility of tanning the ovine stomach into novelty leather and leather products. The ovine stomach was converted into an exotic leather using oil tanning methodology, with goat oil as a tanning agent. The rumen and reticulum parts of the stomach were taken through pre-tanning, tanning and post-tanning operation. The resultant leather had a different grain from the ordinary leather. Then mechanical operations like drying, toggling and staking were done. Physical properties of the leathers were analyzed by determining their thickness, tensile strength, elongation at break, tear strength, flex endurance and ball burst extension test. The grain structure of the leathers was analyzed using a light microscope. The results of physical tests were poor compared to the grains of conventional leathers since the composition of raw outer coverings of animals and those of the stomach are different. The leather processed from this non-conventional source has been found suitable for manufacturing fancy small leather goods like coin purse, key holders, purses and wallets.
用羊胃制取异域皮革及小皮具
用珍奇动物皮或稀有动物部位制成的皮革具有很好的市场价值。异国皮革通常是首选,因为它们的图案,自然产生的痕迹和其独特的结构。本研究的目的是探讨将羊胃鞣制成新型皮革和皮革制品的可行性。用山羊油作为鞣制剂,将羊胃转化为一种奇异的皮革。分别在晒前、晒后和晒后取瘤胃和胃网部分。合成的皮革具有与普通皮革不同的纹理。然后进行机械操作,如干燥、翻转和打桩。通过测定皮革的厚度、拉伸强度、断裂伸长率、撕裂强度、弯曲耐久性和球爆拉伸试验,分析了皮革的物理性能。用光学显微镜对皮革的颗粒结构进行了分析。与传统皮革的颗粒相比,物理测试的结果较差,因为动物的原始外层覆盖物和胃的成分不同。从这种非传统来源加工的皮革被发现适合制造精致的小皮革制品,如硬币钱包、钥匙夹、钱包和钱包。
