Abstract
"PROCESSO PARA FORMAR FIBRAS LYOCELL, E, FIBRA LYOCELL". Um líquido de dopagem contendo celulose é extrusado através de orifícios e em uma corrente de gás movendo-se em uma direção geralmente paralela à direção em que os filamentos são formados, com graus variáveis de atenuação mecânica provida aos filamentos usando um dispositivo de recolhimento, tal como uma bobinadora.
