摘要： A moisture vapor permeable sheet material is comprised of a homogeneous admixture of a synthetic polymer material and a protein derivative. The sheet material is moisture vapor permeable and non-penetrable by liquid water. The sheet material additionally can have coated thereon a pressure sensitive adhesive which is comprised of a synthetic organic polymer adhesive and a soluble protein derivative in solid solution. Sheet material is formed by providing a homogeneous fluid solution of a soluble protein derivative and a synthetic organic polymer in a solvent. The protein derivative has a pH level compatible with the pH level of the organic polymer. Film is formed from the homogeneous fluid solution and the solvent is removed from the film to form the sheet material which is moisture vapor permeable. When the sheet material includes an adhesive, the adhesive is coated as a fluid solution in a solvent on one side of the sheet material.

摘要： A method of forming soluble collagen fibers from raw animal hides is disclosed. Raw animal hides are treated with an aqueous solution of an alkali metal hydroxide and a dehydrating agent to remove the hair and fat therefrom to yield a substantially fat-free corium. The interfibular bonds of the collagen in the corium are stabilized with an aqueous solution of an alkali sulfate. The corium is neutralized and dissolved in an aqueous acid solution to yield a collagen solution. The pH of the aqueous collagen solution is adjusted to the isoelectric point of the collagen to precipitate the collagen fibers from the solution. The collagen fibers are dried. The collagen fibers so produced are useful in edible food, may be redissolved and further processed for a plurality of uses.
摘要翻译：公开了从生动物皮革形成可溶性胶原纤维的方法。用碱金属氢氧化物和脱水剂的水溶液处理生的动物皮革，以从其中除去毛发和脂肪，从而产生基本上无脂肪的corium。使用碱金属硫酸盐水溶液使corium中的胶原蛋白的界面内键稳定。将中和并溶解在酸水溶液中以产生胶原溶液。将胶原水溶液的pH调节至胶原的等电点，以从溶液中沉淀胶原纤维。将胶原纤维干燥。如此生产的胶原纤维在食用食品中是有用的，可以重新溶解并进一步加工用于多种用途。
