Abstract

<B>"EMBALAGEM PERMEáVEL PARA FORNECIMENTO GRADUAL DE MATERIAL CURTENTE E PROCESSO PARA CURTIMENTO DE COURO"<D>. A presente invenção refere-se a aperfeiçoamento desenvolvido em um processo para curtimento de couro que emprega um novo método de fornecimento gradual de material curtente por meio de uma embalagem permeável a líquidos que é introduzida integralmente no interior do banho. O processo proposto é aplicável em curtimento estático (tanques) ou em fulões e caracteriza-se por compreender a dissolução gradual e automática do material curtente em pó no interior do banho ao longo de todo o processo de curtimento, que é determinada pelo material permeável com que é executada a embalagem, sendo que a dita embalagem que acondiciona o material curtente em pó é juntamente com o seu conteúdo incorporada no banho de curtimento. A invenção também prevê a embalagem aplicável nesses processos de curtimento, que caracteriza-se por ser executada com material permeável aos líquidos. O material permeável com que é executada a embalagem é, preferencialmente, um não-tecido. O material não-tecido pode ser produzido, particularmente, com filamentos de polipropileno ou poliéster.<B> "PERMEABLE PACKAGE FOR GRADUAL SUPPLY OF CURTAIN MATERIAL AND PROCESS FOR LEATHER LEATHER" <D>. The present invention relates to an improvement developed in a leather tanning process that employs a new method of gradually supplying tanning material through a liquid-permeable packaging that is integrally introduced into the bath. The proposed process is applicable to static tanning (tanks) or drums and is characterized by comprising the gradual and automatic dissolution of the tanning powder material inside the bath throughout the tanning process, which is determined by the permeable material with that the packaging is carried out, and the said packaging that contains the powdered tanning material is together with its content incorporated in the tanning bath. The invention also provides for the packaging applicable in these tanning processes, which is characterized by being made with liquid-permeable material. The permeable material with which the packaging is made is preferably non-woven. The non-woven material can be produced, in particular, with polypropylene or polyester filaments.
