Abstract
"FIBRA, PROCESSOS DE FIAçãO DE UMA SOLUçãO DE CRISTAL LìQUIDO DE FORMIATO DE CELULOSE E DE OBTENçãO DE UMA FIBRA E UTILIZAçãO DA FIBRA". Fibra de formiato de celulose, de origem de cristal líquido, tendo um alongamento em ruptura importante e apresentando as características seguintes: (a) sob microscópio ótico de polarização, seus filamentos apresentam uma estrutura de fita típica de sua origem de cristal líquido; (b) ela apresenta as relações seguintes: DS<SYM>2; Ar<SYM>8; Te<45; Mi>500; Er>10, DS sendo o grau de substituição da celulose em grupos formiato na fibra (em %), Ar o alongamento em ruptura (em %) da fibra, Te sua tenacidade (em cN/tex), Mi seu módulo inicial em (cN/tex) e Er sua energia em ruptura (em J/g). Processo de obtenção desta fibra de formiato de celulose por fiação "dry-jet-wet" de uma solução de cristal líquido de formiato de celulose, na qual se usa água como agente coagulante. Fibra de celulose regenerada a partir de formiato de celulose, apresentando, ela mesma, um valor elevado de alongamento em ruptura, e processo para obter esta fibra.
