Non-rewet leather and method of producing same |
摘要 |
The present invention relates to the treatment of leather and more particularly to a novel non-rewet dry cleanable leather, and the treatment method by which it is produced. The water-resistance property of a leather which has been treated with a polymeric phosphate ester syntan is significantly improved by subsequently subjecting such a treated leather to a non-aqueous solvent extraction procedure.
