Abstract

Se proporciona un compuesto no tejido que exhibe propiedades elásticas latentes. El compuesto es formado de una capa de hilo elástico laminada a un recubrimiento de tela no tejida. La elasticidad latente puede ser impartida a la capa de hilo elástico a través de la combinación de un elastómero termoplástico y una poliolefina capaz de formar los dominios semi cristalinos entre las cadenas elastoméricas. Más específicamente, capa de hilo elástico puede ser estirada en una ó más direcciones para orientar las cadenas de elastómero. Sin intentar el estar limitado por la teoría, los presentes inventores creen que el estado orientado de las cadenas puede ser mantenido en el lugar por dominios semi cristalinos relativamente rígidos de la poliolefina. La capa de hilo elástico estirada subsecuentemente puede ser relajada y unida a un recubrimiento de tela no tejida para formar el compuesto. El compuesto puede ser posteriormente activado (por ejemplo calentado) para encoger la capa de hilo elástico y proporcionar está con un estiramiento "latente". Por ejemplo, el compuesto puede ser calentado a o arriba de la temperatura de suavizamiento de la poliolefina para suavizar los dominios cristalinos y permitir a las cadenas el regresar a su estado no orientado. Como un resultado de la presente invención, la capa de hilo elástico puede ser extendida y ser recuperada de su estado no orientado.
