Abstract

"EQUIPAMENTO PARA A PREPARAçãO DE SOLUçãO AQUOSA ALCALINA DE HIDROSSULFITO DE SóDIO E USO DE UM EQUIPAMENTO". A presente invenção se refere a um equipamento para a preparação de solução alcalina de hidrossulfito de sódio utilizada para o tingimento de material têxtil celulósico com corantes a tina. O equipamento, de acordo com a presente invenção, compreende um vaso fechado com paredes isoladas termicamente, no interior do qual se dispõem pelo menos um agitador e pelo menos um trocador de calor, além de meios para manter uma atmosfera positiva e inerte dentro do dito vaso fechado e meios para a transferência da solução contida no dito vaso fechado. O equipamento é vantajosamente empregado para a preparação de solução de de corante a tina como, por exemplo, o corante índigo blue, também conhecido como Vat Blue 1 e identificado no Color lndex com o número 73.000, através de redução química na presença de um agente alcalino, por exemplo o hidróxido de sódio, e de um agente redutor, por exemplo o hidrossulfito de sódio, obtendo-se o índigo blue reduzido, também conhecido como Vat Blue 1 Reduced."EQUIPMENT FOR THE PREPARATION OF Aqueous ALKALINE HYDROSULPHITE SOLUTION AND USE OF AN EQUIPMENT". The present invention relates to equipment for the preparation of alkaline sodium hydrosulphite solution used for dyeing dye-dyed cellulosic textile material. The apparatus according to the present invention comprises a closed vessel with thermally insulated walls within which at least one stirrer and at least one heat exchanger are provided, and means for maintaining a positive and inert atmosphere within said apparatus. closed vessel and means for transferring the solution contained in said closed vessel. The equipment is advantageously employed for the preparation of dye-to-dye solution such as indigo blue dye, also known as Vat Blue 1 and identified in Color lndex with the number 73,000 by chemical reduction in the presence of an agent. alkaline, for example sodium hydroxide, and a reducing agent, for example sodium hydrosulfite, to yield reduced indigo blue, also known as Vat Blue 1 Reduced.
