    摘要： Semifinished products or leather are or is produced by a process in which pelts, pickled pelts or semifinished products are treated with a) at least one sheet silicate and b) at least one copolymer which is obtainable by copolymerization of at least one ethylenically unsaturated dicarboxylic anhydride (A), derived from at least one dicarboxylic acid of 4 to 8 carbon atoms, at least one vinylaromatic compound (B1) or at least one oligomer (B2) of branched or straight-chain C2-C10-alkene, at least one oligomer having an average molecular weight Mn of from 300 to 5 000 g/mol or being obtainable by oligomerization of at least 3 equivalents of C2-C10-alkene, and optionally at least one ethylenically unsaturated monomer (C) differing from (A) and having at least one hetero atom, and reaction with at least one compound (D) of the formula I a or I b and optionally hydrolysis with water or aqueous alkaline solution, where, in formula I a and I b, A1 are identical or different and are C2-C6-alkylene R1 is linear or branched C1-C20-alkyl and n is an integer from 1 to 200.

    摘要： The process for making a leather article structure consists of homogeneously applying a layer of substantially uniform thickness of an unpolymerised acetic silicone-based material onto the back of a leather layer, making it penetrate into the natural pores present on the back of the leather layer, and polymerising the acetic silicone-based material so as to make a support layer for the leather layer.

    摘要： Pigskin is processed to provide a bleached, expanded skin used in dog treat or chew products. The raw pigskin is dehaired and then daubed with an alkali mixture of an alkali liquid, alkali enzymes and lime, the mixture having a pH of greater than or equal to 12. The alkali mixture dissolves the colloidal protein. The alkali is removed by alternately rinsing the skin in water and agitating the skin with first ammonium chloride or ammonium sulfate, and then second with ammonium chloride or ammonium sulfate, and pancreatic enzymes. The skin is agitated with sodium carbonate and a degreaser to remove the fat. The skin is then washed with hydrogen peroxide, which bleaches and expands the skin. The skin is then formed into a dog product and dried.
