摘要： The present process yields superior leather materials from limed hides, without the use of chromium salts, by combining a series of essential method steps in a sequence which yields leather having a "chrome" character. The present chromium-free tanning process includes the method steps of pretanning a hide with a chromium-free tan until its shrinkage temperature is about 170.degree. to 185.degree. F., submerging the hide in an acidic brine, having a pH between 2.5 and 3.5, and adding (in sequence, and in amounts sufficient to yield specified concentrations of each) pretanning agents, syntans, vegetable extracts, neutralizing agents and retanning and finishing agents, all of which are free from chromium. This method of pretanning, tanning and retanning a hide with a specified sequence of particular concentrations of chromium-free reagents yields a leather product having the characteristics of chrome-tanned leather and which demonstrates superior shrink resistance, resilience and flexural strength. The resultant leather product has particular utility when incorporated into durable, weather-resistant footwear such as military shoes and boots, but is likewise suitable for use in other applications which require durable, attractive leather goods such as handbags and attaches.
摘要翻译：本发明方法通过在产生具有“铬”特性的皮革的序列中组合一系列必需的方法步骤，从而不使用铬盐，从有色皮革产生优良的皮革材料。本发明的无铬鞣制方法包括以无铬棕褐色预鞣皮的方法步骤，直到其收缩温度为约170至185°F，将皮革浸入酸性盐水中，pH在2.5至3.5之间，并且加入（按顺序，并且以足以产生每种的指定浓度的量）预处理剂，合成鞣剂，植物提取物，中和剂和复鞣整理剂，所有这些都不含铬。这种用特定浓度的无铬试剂预定鞣制和复鞣皮革的方法产生具有铬鞣皮革特征的皮革制品，并且具有优异的抗收缩性，弹性和弯曲强度。所得到的皮革产品在结合到耐用的耐候性鞋类如军用鞋和靴子中时具有特别的用途，但同样适用于需要耐用，有吸引力的皮革制品如手袋和附件的其它应用。

摘要： A method of forming a collagen-thrombin hemostatic composition is comprised of forming a homogeneous aqueous admixture of collagen and thrombin at a basic pH and lyophilizing the collagen-thrombin admixture to form a stable collagen sponge having thrombin therein. The collagen utilized in the process is absorbable when placed in vivo. Additionally, a lyophilized collagen product is comprised of collagen which is absorbable when placed in vivo and thrombin distributed within the collagen. The collagen product is storage stable.

摘要： Macromolecular reconstituted collagen is prepared by treating natural insoluble collagen with an aqueous solution comprised of an alkali sulfate salt and an alkali metal hydroxide for at least 48 hours to saponify fats suspended within the natural insoluble collagen. The fat free collagen is then treated with an aqueous solution comprised of an alkali metal sulfate for at least four hours to stabilize the interfibular bonds between individual polypeptide chains. The collagen is then dissolved in an aqueous acid solution and frozen at a rate of -20.degree. C./hour. The frozen collagen is vacuum dried at 10.sup.-3 to 10.sup.-5 torr for at least 16 hours to produce a biologically active collagen article. Various biologically active materials may be added to the aqueous acid solution prior to freezing. The collagen product may then be implanted into an animal or the like and the medication slowly released. The article can remain within the biological system and it will slowly dissolve due to enzymatic digestion and through other biological processes.

摘要： A leather finishing process in which, in pertinent part, a warm water milling step is added after the base coat is applied to nullcrustnull leather and cured. The warm water contains at least one dye fixation agent including but not limited to about 0.1-2.0% by weight of formic acid. Moreover, the base coat itself is an aqueous base coat containing at least two polymers such as an acrylic salt or a polyurethane salt. Between the polymeric constituents of the base coat, the acid fixation agent, and the use of the warm water milling step after the base coat has been applied and dried, a surprisingly natural feel to the leather is attained without loss of excellent adhesion, wear-resistance and other properties when the leather is completely finished.

摘要： Manufacture of grain and split leather is simplified by pre-tanning hide with a chromium-free tan until its shrinkage temperature is about 170.degree. to about 185.degree. F, splitting the pre-tanned hide to provide a grain intermediate and a split intermediate, shaving at least one of these intermediates, and chrome-tanning the shaved intermediate. Shavings contain no chromium and can be disposed of by dumping, without significant environmental impact. Before splitting, the hide can also be pickled to improve the splitting and shaving and make the unfinished hide better suited for shipping to remote geographical areas. Entire hide treatment sequence can be effected with two stages in which batches of hides are loaded in a container such as tumbling drum; unhairing, bating and pre-tanning with or without a pickle, all in one stage, and final tanning, coloring and fat-liquoring in another stage. Final chrome-tanned product has very good physical characteristics including unusually high slot tear and is recovered in higher yield.
