Abstract: The invention relates to an automated method for inspecting and correcting the surfaces of flat materials, for example, leather. The invention particularly relates to a method for classifying surfaces of flat materials involving the following steps: (a) preparing a material; (b) optoelectronically sensing the surface of the material; (c) determining the number of defects; (d) determining the volume of defects and subsequently conducting an automatic classification of the flat materials based on the number and volume of defects.

Abstract: N-Vinyl-containing polymers obtainable by free-radically initiated polymerization of a monomer or monomer mixture of(A) from 5 to 100% by weight of an N-vinylamide or N-vinylamine,(B) from 0 to 95% by weight of monoethylenically unsaturated carboxylic acids having from 3 to 8 carbon atoms or their derivatives,(C) from 0 to 95% by weight of other N-vinyl and/or C-vinyl compounds and(D) from 0 to less than 10% by weight of other copolymerizable monomers,are useful in the form of aqueous solutions or dispersions as tanning materials for self-tanning, pretanning and cotanning of leather pelts and fur pelts and for retanning leather and fur.

Abstract: The invention relates to a method for producing a three-dimensional molded part that comprises a carrier produced from a thermoplastic polymer and a leather layer applied on said carrier. Said leather and said thermoplastic polymer are linked by means of a tool that has a molding surface on which the leather comes to rest at a pressure of at least 50 bar, preferably of more than 100 bar, especially more than 180 bar, and at a temperature of more than 100 DEG C, preferably 180 to 280 DEG C, especially 200 to 250 DEG C, with the molding surface of the tool that rests against the leather being tempered. The invention provides a method for intimately linking the carrier and the leather layer. The molded articles produced by the inventive method have a substantially improved resistance to the effects of temperature or moisture variations.

Abstract: The invention relates to the use of polymers containing n-vinyl units, obtained by radically initiated polymerization of a monomer or a monomer mixture consisting of (A) 5 to 100 wt.% n-vinylamides or n-vinylamines; (B) 0 to 95 wt.% monoethylenically unsaturated carboxylic acids with 3 to 8 C atoms or the derivatives thereof; (C) 0 to 95 wt.% n-vinyl or C-vinyl compounds and (D) 0 or less than 10 wt.% copolymerizable monomers. Said polymers are used in the form of aqueous solutions or dispersions for self-tanning, pre-tanning or co-tanning smoothed skins and pelts and for retanning hides and fells.
