Title (EN) METHOD FOR FINISHING LEATHER
(FR) PROCÉDÉ D'ENNOBLISSEMENT DU CUIR
(DE) VERFAHREN ZUR VEREDELUNG VON LEDER
Abstract:
(EN) The invention relates to measures for treating and finishing leather. In particular, the invention relates to a method for producing leather shrinkage, comprising the following steps: a) washing at least one chromium-tanned hide (chromium wet blue) in a washing solution, b) neutralizing the treated hide in a neutralization solution, c) pre-stuffing the hide, d) dyeing the hide in a dyeing solution, e) stuffing by adding stuffing agent mixture, f) fixating by adding formic acid, g) setting the final shade, h) fixating, i) washing the hide, j) drying the hide, k) applying a binder mixture solution, l) applying an aqueous emulsion lacquer based on polyurethane, m) ironing and staking the hide, n) drumming the hide while continuously supplying moisture, o) removing moisture from the hide, p) climatizing the hide and further reducing the moisture content, and q) applying a fixating solution.
(FR) L'invention concerne des mesures pour le traitement et l'ennoblissement du cuir. Elle concerne en particulier un procédé de fabrication de cuir rétracté comprenant les étapes suivantes : a) le lavage d'au moins une peau tannée au chrome (chromwetblue) dans une solution de lavage ; b) la neutralisation de la peau traitée dans une solution de neutralisation ; c) le pré-graissage de la peau ; d) la coloration de la peau dans une solution de teinture ; e) le graissage par addition de mélange d'agents de graissage ; f) la fixation par addition d'acide formique ; g) le réglage de la teinte finale ; h) la fixation ; i) le lavage de la peau ; j) le séchage de la peau ; k) l'application d'une solution de mélange de liants ; l) l'application d'une émulsion de laque aqueuse à base de polyuréthane ; m) le repassage et le roulage de la peau ; n) le foulage de la peau sous apport continu d'humidité ; o) la déshumidification de la peau ; p) le conditionnement de la peau et la réduction ultérieure de la teneur en humidité ; et q) l'application d'une solution de fixation.
(DE) Die Erfindung betrifft Maßnahmen zur Behandlung und Veredelung von Leder. Insbesondere betrifft sie ein Verfahren zur Herstellung von Lederschrumpf umfassend die folgenden Schritte a) Waschen zumindest eines Chrom-gegerbten Fells (Chromwetblue) in einer Wasch- Lösung, b) Neutralisieren des behandelten Fells in einer Neutralisations-Lösung, c) Vorfettung des Fells, d) Färbung des Fells in einer Färbe-Lösung, e) Fettung durch Zugabe von Fettungsmittelgemisch, f) Fixierung durch Zugabe von Ameisensäure, g) Endtoneinstellung, h) Fixierung, i) Waschen des Fells, j) Trocknen des Fells, k) Auftragen einer Bindermischungs-Lösung, l) Auftragen eines wässrigen Emulsionslack auf Polyurethanbasis, m) Bügeln und Stollen des Felles, n) Walken des Felles unter kontinuierlicher Feuchtigkeitszufuhr, o) Entfeuchten des Fells, p) Klimatisierung des Fells und weitere Reduktion des Feuchtigkeitsgehalts und q) Auftragen einer Fixierungs-Lösung.
