Abstract

processamento de fibra celulósicao. o fortalecimento da tenacidade a seco e úmido das fibras celulósicas regeneradas pode ser realizado por meio da adição de um ácido aldárico, como (mas não se limitando a) ácido glucárico. em algumas modalidades, as fibras celulósicas regeneradas que incluem um ácido aldárico ou um sal do mesmo, produzidas pelos métodos descritos, também são descritas. as fibras produzidas apresentam propriedades vantajosas devido, pelo menos em parte, à inclusão do ácido aldárico.
