Abstract

"MéTODO PARA PRODUZIR UM ARTIGO ELáSTICO ESTIRADO FINO QUE POSSUI ESTABILIDADE DIMENSIONAL AO LONGO DO TEMPO E A TEMPERATURAS ELEVADAS". Um método para produzir um artigo elástico estirado fino que possui estabilidade dimensional ao longo do tempo e a temperaturas elevadas no qual um copolímero termoplástico de blocos é processado por fusão em um artigo estirável tal como uma película ou fibra. o artigo e em seguida condicionado a uma temperatura elevada maior ou igual à temperatura de transição do vidro (T.) de uma fase dura do copolímero termoplástico de blocos. O artigo é estirado fino à temperatura elevada até um estiramento percentual desejado, formando um artigo estirado fino, após o que é esfriado até uma temperatura abaixo da temperatura de transição do vidro da fase dura do copolímero termoplástico de blocos. Películas produzidas por este método são adequadas para uso em artigos duráveis e descartáveis incluindo artigos de higiene pessoal tais como fraldas, vestuário para incontinência, calças de treinamento e artigos de higiene feminina, assim como compressas para ferimentos, lenços, toalhas, guardanapos e vestes protetoras.
