Abstract

1343918 Retanning and fatliquoring leather BADISCHE ANILIN- & SODA-FABRIK A G 16 Nov 1971 [17 Nov 1970] 53103/71 Heading C6C Leather which has been tanned with chrome or vegetable tanning materials is treated on the grain side only with retanning materials, fatliquoring agents and, optionally, wetting agents and dyes. The retanning and fatliquoring materials may be applied together or in succession, in single or multiple applications, by brushing, spraying or curtain coating. Suitable retanning materials, dissolved in water or water-miscible organic solvents, are commercial vegetable tanning materials, condensation products of phenols or naphthols with formaldehyde, aromatic sulphonic acids with formaldehyde, urea/formaldehyde condensates, dicyanodiamide and melamine/ formaldehyde condensates, acrylic resin dispersions, glutardialdehyde and basic mineral tanning salts. To these may be added any of the usual fatliquoring agents e.g. products based on sulphonated, sulphated, animal and vegetable oils and fats and/or synthetic oils based on chlorinated, sulphochlorinated and saponified paraffin or olefin derivatives or emulsions of animal, vegetable or synthetic oils produced using cationic or non-ionic emulsifiers. Cationic, non-ionic, or anionic wetting agents may be used, e.g. polyoxyalkylated, hydrocarbon-active compounds, fatty alcohol sulphonates or condensation products with amines, urea derivatives and tertiary nitrogen bases. Any of the usual leather dyes, e.g. azo or complex dyes, may also be used.
