Abstract

LA PRESENTE INVENCIÓN SE REFIERE A MÉTODO PARA FORMAR UNAPELÍCULA ABIERTA DE UN MATERIAL POLIMÉRICO TERMOPLÁSTICO ESTIRABLE QUE COMPRENDE: a) proveer una película iniciadora que comprende dicho material polimérico termoplástico estirable y que tiene un lado superior y un lado inferior tratado con descarga en corona; b) proveer un miembro de sostén que comprende regiones de soporte localizadas para sostener dicha película iniciadora, zonas de depresión en las que puede formarse la película por medio de la aplicación de fluidos, y un medio para permitir que dicho fluido sea transportado fuera de dicho miembro de sostén; c) sostener dicha película iniciadora sobre dicho miembro de sostén con porciones del lado inferior de dicha película en contacto con las regiones de sostén de dicho miembro de sostén y con el lado superior de dicha película alejándose de dicho miembro de sostén, d) dirigir un fluido en la forma de flujo en columna desde por lo menos dos grupos de orificios contra el lado superior de dicha película iniciadora en una zona de contacto, los orificios del primer conjunto tiene un diámetro mayor que diez mil y el fluido provisto allí tiene una presión menor a los 500 psig. para provocar la formación de agujeros grandes en dicha película iniciadora; los orificios del segundo grupo tienen un diámetro menor o igual a 10 mil y el fluido provisto allí tiene una presión de por lo menos 500 psig para provocar la formación de micro-agujeros en dicha película iniciadora, de este modo, se forma una combinación de agujeros grandes y microagujeros en dicha película iniciadora; e) mover dicha película de dicha zona de contacto; f) revestir el lado superior de dicha película abierta con un agente activo de superficie; y g) enrollar dicha película abierta en un rodillo con dichos lados superior e inferior en contacto superficie con superficie, donde por lo menos una porción de dicho agente activo de superficie se transfiere del lado superior de la película hasta el lado inferior. ...
