Abstract
Procedimiento para el tratamiento del cuero durante su curtido, tal como un tratamiento desengrasante y precurtidor de cuero en tripa, para un curtido y curtido ulterior de pieles de pelo y cuero, así como para una neutralización de los cueros, caracterizado porque en una primera etapa se preparan silicatos de aluminio alcalino, de partícula fina, insoluble en agua, preferentemente conteniendo agua, de fórmula: (cat2/n0)x. Al2o3. (si0)2 y'' donde cat significa unión de metal alcalino, preferentemente un ión sodio, x representa un número de 0,7-1,5 e y un número de 0,8-6, preferentemente 1,3-4, con un tamaño de partícula de 0,1 hasta 25u, preferentemente 1 hasta 12 u, y que tiene un capacidad ligadota de calcio de 20-200 MG de Ca0/g de sustancia activa anhídrido, por reacción de aluminato alcalino o silicato alcalino, preferentemente en solución acuosa, separación y secado del productos, por tratamiento hidrotermico de caolina calcinada con alcali acuoso y separación y secado del producto y,en una segunda etapa, los solícitos de aluminio alcalino, así obtenidos, se suspenden en agua en una cantidad de 5-80 gol y, en caso dado, se agregan agentes tensioactivos anionicos y/o no ionicos en una cantidad de 10 -50 g/l y/o curtientes al cromo, curtientes sintéticos y/0 vegetales y con esta flota de tratamiento se tratan o batanan los cueros en tripa o pieles a 15-50ºC en la zona ph ácida durante 10-300 minutos, con lo que se presenta una reacción con los colágenos de las fibras de cuero, y a continuación se enjuaga con agua.
