Abstract

"MATERIAL ELáSTICO COMPOSTO RESPIRáVEL TENDO UMA CAMADA DE PELìCULA ELASTOMéRICA CELULAR E MéTODO PARA SUA FABRICAçãO". Um material e método para proporcionar um laminado de pelo menos duas camadas para proporcionar respiração e propriedades de barreira de umidade sem reduzir apreciavelmente as propriedades elásticas. Um primeiro material compreende uma trama tecida ou não-tecida e um segundo material compreende uma fibra ou película elastomérica celular. Tais materiais podem ser integrados a um laminado através da formação do referido primeiro material no referido segundo material ou através da união dos dois materiais através de meios químicos ou físicos, tais como o uso de adesivos. O segundo material pode ser preparado pela mistura de um agente de abertura de células com a resina de polímero elastomérico e extrusando a mistura em condições adequadas, em que o agente de abertura de células decompõe-se ou reage para liberar um gás que forma células na película elastomérica. O material é útil em produtos para cuidados pessoais, tais como fraldas, produtos para higiene feminina, produtos para higiene infantil, produtos para incontinência e produtos para cuidados da saúde, em que tais propriedades são desejáveis para atributos tais como conforto, modelagem do corpo, conformidade, secura e semelhantes."RESPIRABLE COMPOSITE ELASTIC MATERIAL HAVING A CELLULAR ELASTOMERIC FILM LAYER AND METHOD FOR ITS MANUFACTURING". A material and method for providing a laminate of at least two layers to provide breath and moisture barrier properties without appreciably reducing elastic properties. A first material comprises a woven or non-woven weave and a second material comprises a cellular elastomeric fiber or film. Such materials can be integrated into a laminate by forming said first material on said second material or by joining the two materials through chemical or physical means, such as using adhesives. The second material can be prepared by mixing a cell opening agent with the elastomeric polymer resin and extruding the mixture under suitable conditions, where the cell opening agent decomposes or reacts to release a gas that forms cells in the elastomeric film. The material is useful in personal care products such as diapers, feminine hygiene products, infant hygiene products, incontinence products and health care products, where such properties are desirable for attributes such as comfort, body shaping, conformity, dryness and the like.
