Abstract

Una banda de fibra se une mutuamente mediante un medio aglutinante que ha sido activado solubilizando parcialmente el medio aglutinante con un solvente para el mismo; las fibras son insolubles en el medio aglutinante se solubiliza parcialmente, se hace pegajoso y fluyen en contacto con las fibras y con sí mismo; después, el solvente es absorbido por el medio aglutinante dejando al medio aglutinante solidificarse nuevamente y une la fibras en una matriz, aumentando la resistencia de la banda.
