Abstract

Se provee un compuesto elástico formado desde un laminado que contiene una película elástica y un revestimiento no tejido de bajo peso con una baja fuerza en la direccion cruzada de la máquina (ôDCö). Debido a la baja fuerza del revestimiento, es deseable que la película elástica tenga un grosor y peso suficiente para incrementar la fuerza del compuesto resultante. Desafortunadamente, la habilidad para unir una película elástica para dicho revestimiento no tejido de bajo peso se torna cada vez más difícil a medida que el grosor de la película aumenta. En este sentido, se ha descubierto que un segundo laminado puede ser utilizado en el compuesto elástico que es formado desde una película termoplástica y un revestimiento no tejido para impartir fuerza aumentada al compuesto. La película y revestimiento del segundo laminado puede estar formado desde los mismos o distintos materiales que la película y el revestimiento del primer laminado. Independientemente, los laminados están posicionados para que las películas elásticas y termoplásticas estén en una relacion cara a cara. A través de control selectivo sobre el contenido polimérico y grosor, se ha descubierto que las películas elásticas y termoplásticas pueden ser unidas juntas bajo presion por luz, incluso en condiciones de temperatura ambiente. Esto evita la aplicacion de una cantidad sustancial de calor utilizado en procesos convencionales de union por calandra, que puede de otro modo danar la película, y también minimizar la necesidad de adhesivos costosos.
