Abstract in Portuguese

O presente trabalho apresenta um estudo comparativo entre os coeficientes de atrito longitudinal e transversal em processos têxteis. Os coeficientes de atrito longitudinal e transversal de amostras de cinco diferentes fios foram determinados experimentalmente nos ensaios capstan e de retorcimento. Os resultados foram comparados e verificou-se que os coeficientes de atrito são diferentes e o coeficiente de atrito transversal determinado pelo ensaio de retorcimento é mais adequado para determinar o coeficiente de atrito nos processos industriais de retorcimento.

Abstract in English

The present work presents a comparative study of the of longitudinal and transversal friction coefficients in textile processes. The coefficients of longitudinal and transversal friction of samples of five different yarns were determined by capstan and twisting tests. The results were compared and it has verified that the longitudinal and transversal friction coefficients are different. The transversal friction coefficient determined by the twisting test is more appropriate to determine the friction coefficient of twisting yarns in the industrial processes.
