Abstract
RAS DE CELULOSE"<D>. A presente imvenção refere-se a um método de produção de fibras de celulose do tipo liocel ao se processar uma solução de celulose fiável em um óxido de amina terciária aquoso de étodo é caracterizado pelo fato de que uma solução contendo um teor entre cerca de 0,05% em massa e 0,70% em massa baseado na massa da solução, de celulose e/ou outro polímero com um peso molecular pelo menos 5 x 10^ 5^ é usado para fiação. O método da presente invenção permite o uso de uma fieira tendo mais de 10.000 orifícios de fiação que é empregado para fiação, cujos orifícios são dispostos de tal maneira que os orifícios de fiação vizinhos são espaçados no máximo 3mm entre si e a densidade linear dos orifícios de fiação é de pelo menos 20.
