Abstract

Patente de Invenção para <B>"FILTROS DE FUMAçA DE TABACO DE áLCOOL POLIVINIL E PRODUTO USANDO TAIS FILTOS, E PROCESSOS E APARELHO PARA FABRICAçãO DOS MESMOS"<D>. Um elemento poroso (20), particularmente para uso como um tamponamento de filtro de fumaça de tabaco em associação com um cigarro (16) ou similar, no qual a matriz compreende uma multiplicidade de fibras de álcool polivinil biodegradáveis ligadas juntas em seus pontos de contato, para definirem uma trajetória intersticial tortuosa para a passagem de fumaça. Devido a natureza higroscópica do álcool polivinil, a produção comercial de tais produtos requer controle cuidadoso do teor de umidade do material de partida da fibra de álcool polivinil, usualmente pré-secagem do mesmo para teor de umidade residual de 7% por peso ou menos, e tratamento da massa fibrosa de baixa umidade pelo vapor super-aquecido para adicionar cerca de 2,5 a 5% de umidade para um teor de umidade final de cerca de 2,5 a 10%. O vapor torna a superfície da fibra adesiva e, desse modo, ligável, e também lubrifica as fibras unidas para aperfeiçoar a processabilidade.
