Abstract

Se describen filtros degradables, así como métodos para hacerlos, que incluyen las etapas de aplicar un plastificante que contiene un agente fotoactivo a las fibras de éster de celulosa para obtener fibras de éster de celulosa plastificadas; y formar las fibras de éster de celulosa plastificadas en un filtro. Las fibras de éster de celulosa pueden comprender acetato de celulosa, el plastificante puede ser triacetina y el agente fotoactivo puede incluir un número de tipos de dióxido de titanio, por ejemplo partículas de dióxido de titanio de fase mezclada. Los filtros son útiles, por ejemplo, en la preparación de filtros de cigarrillo.
