Abstract

Se refiere a un proceso para formar una tela polimérica de una sola capa humectable duraderamente que tiene una pluralidad de perforaciones. Esteproceso comprende fundir una mezcla de por lo menos un polímero termoplástico y por lo menos unsurf actante desplazable y extruir la mezcla para formaruna película polimérica sustancialmente continua de una sola capa. La película luego se perfora utlizando flujos hidráulicos de alta presion. La formacionde perforaciones se realiza cuando lapelícu la polimérica de una sola capa tiene un ángulo de contacto de por lo menos 30* aproximadamente, para minimizarel desplazamiento fuera del surfactante impregnado en la tela polimérica. También se refiere a telas perforadashumectables durad eramente.
