Abstract

"MATERIAL ELáSTICO LAMINADO E PROCESSO PARA FORMAR UM MATERIAL ELáSTICO POSSUINDO ALTA ELASTICIDADE". Um laminado que possui uma extensibilidade aperfeiçoada é feito de uma camada de folha elástica pré-esticada e ligada a pelo menos uma camada extensível. Em uma primeira modalidade, a camada elástica é ligada em locais selecionados a uma camada extensível e, então, aquecida. A extensibilidade latente da camada elástica pré-esticada e a extensibilidade da camada extensível produzem a extensibilidade desejada que é útil em cintas, acolchoamentos laterais e abas laterais de fraldas e calças plásticas. Fraldas e calças plásticas feitas com tal material podem caber em um grande número de tamanhos de manequim devido a sua extensibilidade aperfeiçoada. Em uma segunda modalidade, a película é pré esticada em direção de cruz e na direção da máquina, e então laminada até uma camada extensível, resultando em uma extensibilidade bidirecional. A camada elástica pode ser furada. Os furos produzem um laminado que é respirável e ao mesmo tempo mantendo a extensibilidade melhorada."LAMINATED ELASTIC MATERIAL AND PROCESS TO FORM AN ELASTIC MATERIAL WITH HIGH ELASTICITY". A laminate that has improved extensibility is made of a layer of pre-stretched elastic sheet and bonded to at least one extensible layer. In a first embodiment, the elastic layer is attached at selected locations to an extensible layer and then heated. The latent extensibility of the pre-stretched elastic layer and the extensibility of the extensible layer produce the desired extensibility that is useful in straps, side padding and side flaps of diapers and plastic pants. Diapers and plastic pants made with such material can fit a large number of mannequin sizes due to their improved extensibility. In a second embodiment, the film is pre-stretched in the direction of the cross and in the direction of the machine, and then laminated to an extensible layer, resulting in a bidirectional extensibility. The elastic layer can be punctured. The holes produce a laminate that is breathable while maintaining improved extensibility.
