Abstract

"PROCESSO PARA A FABRICAçãO DE ARTIGOS MOLDADOS DE CELULOSE". A presente invenção se refere a um processo para a fabricação de artigos moldados de celulose, tais como fibras, filamentos, ou películas, a partir de celulose lixiviada com TCF ou lixiviada com ECF, no qual a celulose lixiviada é dissolvida em um aminoxido terciário aquoso para formar uma solução de celulose moldável, a solução de celulose se deforma, e o artigo moldado origina-se pela coagulação da solução deformada, caracterizado pelo fato de que para reduzir a decomposição da celulose no processo, é usada a celulose lixiviada com TCF compreendendo um conteúdo de grupo carboxil na faixa de 1 a 35 <109>mol/g ou celulose lixiviada com ECF com um conteúdo de grupo carboxil ha faixa de 1 a 50 <109>mol/g. Os artigos moldados possuindo uma reduzida decomposição de celulose podem ser formados pelo dito processo.
