Abstract

PRODUTO DE VISCOSE A invenção refere-se a uma polpa com um alto nível de hemicelulose que é misturada com uma polpa de grau de dissolução e convertida em viscose. A misturação pode ser realizada durante a impregnação ou após a impregnação. A fiação da viscose contendo a mistura, em filamentos, produz fibras com propriedades de resistência que são pelo menos iguais àquelas da polpa de dissolução sozinha.
