Abstract

compósito elástico contendo revestimento não tecido leve e de baixa resistência. a presente invenção provê um compósito elástico formado a partir de um revestimento não tecido leve que apresenta baixo grau de resistência na direção transversal à máquina (''cd''). através de controle seletivo sobre certos parâmetros dos materiais empregados no compósito e processo de formação, os presentes inventores descobriram que tais revestimentos leves e de baixa resistência podem ser prontamente laminados em um filme elástico sem danificar significativamente sua integridade. por exemplo, em uma modalidade, o filme elástico pode possuir uma construção de multicamadas que inclui uma camada elástica elastomérica posicionada adjacente a uma camada termoplástica para aumentar a resistência. o teor de polímero e a espessura da camada termoplástica são genericamente selecionados para conferir resistência e integridade adicionais ao filme. de modo semelhante, o teor de polímero da camada elástica também pode ser selecionado de modo que o filme possua uma pega suficiente para aderir ao revestimento. em certos casos, pode ser desejável posicionar a camada entre duas camadas elásticas de modo que a camada de aumentar a resistência não contate substancialmente o revestimento não tecido. desse modo, a camada de aumentar a resistência pode evitar dano substancial durante o processo de laminação.
