Abstract

<B>MATERIAL ELáSTICO COMPOSTO APERFEIçOADO E PROCESSO PARA PRODUçãO DO MESMO<D> A presente invenção refere-se a materiais laminados elásticos latentes e/ou estáveis dimensionalmente. O método de produção de materais elásticos compostps inclui fornecimento de um material polimérico possuindo um primeiro comprimido, estiramento do material polimérico para um segundo comprimento e barreira com pleo menos um foceamento sem algodão ao material polimérico em um calendário constituído de dois rolos de superfície, de tal forma que o componente elástico não é danificado ou precondicionado para danificar durante o uso do artigo de higiene pessoal em que o material elástico composto é utilizado.<B> PERFECTED ELASTIC COMPOUND MATERIAL AND PROCESS FOR THE SAME PRODUCTION <D> The present invention relates to latent and / or dimensionally stable elastic laminated materials. The method of producing elastic composite materials includes supplying a polymeric material having a first tablet, stretching the polymeric material to a second length and barrier with pleo minus a cotton-free focusing of the polymeric material in a calendar consisting of two surface rolls, of such that the elastic component is not damaged or preconditioned to damage during the use of the personal hygiene article in which the composite elastic material is used.
