Abstract

<B>USO DE UM AGENTE TENSOATIVO ANFóTERO COMO ADITIVO DE BANHO DE FIAçãO DE VISCOSE<D> A presente invenção refere-se a um método de reduzir a obstrução de bocais e fendas e diminuir a formação de depósitos no sistema de banho de fiação no processo de fabricação de materiais de filme e filamentares de viscose utilizando um agente tensoativo anfótero tendo a fórmula (I) : RNA ((C~ n~H~ 2n~ NA) ~ x-1~A onde R representa um hidrogênio ou um grupo alifático com 1-24 átomos de carbono, cada A representa um hidrogênio, um grupo alifático com 1-24 átomos de carbono, ou grupos BOOCC~ m~H~ 2n~ - onde m é um número de 1-3, B é hidrogênio ou um cátion de formação de sal, n é um número de 2-3, x é 1-8, e o número dos grupos BOOCC~ m~H~ 2n~ é de 1 a x+2, com a condição de que o número total de átomos de carbono nos grupos alifáticos seja de 8 a 45. O agente tensoativo anfótero tem um excelente efeito anti-obstrução, uma vez que é um bom dispersante e evita ou reduz a precipitação no banho de fiação. Além disso, tem baixa formação de espuma e é muito estável.
