Abstract
Una fibra de polímero hidrofobico que tiene un recubrimiento cargado cationicamente sobre la misma en la cual el recubrimiento incluye un polímerocationico funcionalizado, tal como una poliamina funcionalizada con epiclorohidrina o una poliamido-amina funcionalizada con epiclorohidrina la cual se haenlazado en forma cruzada por calor. La presente invencion también proporciona un filtro fibroso el cual incluye las fibras de polímero hidrofobico que tienenel recubrimiento cargado cationicamente anterior sobre las mismas. La presente invencion además proporciona un método para preparar un filtro fibroso. Elmétodo involucra el proporcionar un filtro fibroso que comprende fibras de polímero hidrofobico; tratar el filtro fibroso con una solucionacuosa de unpolímero cationico funcionalizado que puede enlazarse en forma cruzada por calor bajo condiciones suficientes para recubrir esencialmente las fibras con elpolímero cationico funcionalizado, en donde la solucion incluye el polímero cationico funcionalizado, un poli (alcohol vinílico), un solvente polar para elpoli (alcohol vinílico) y agua; y tratar el filtro fibroso recubierto resultante con calor a una temperatura y por un tiempo suficiente para enlazar en formacruzada el polímerocationico funcionalizado presente sobre las fibras de polímero hidrofobico. La presente invencion adicionalmente proporciona un método parapreparar un filtro fibroso. El método incluye el proporcionar un filtro fibroso compuesto de fibras de polímerohidrofobico; pasar una solucion del polímerocationico funcionalizado que puede enlazarse en forma cruzada por calor a través del filtro fibroso bajo condiciones suficientes para recubrir esencialmentelas fibras con el polímero cationico funcionalizado, en donde la solucion incluye el polímero cationico funcionalizado, un poli (alcohol vinílico), y agua, yel tratar el filtro fibroso recubierto resultante con calor a una temperatura y por un tiempo suficiente para enlazar en forma cruzada el polímero cationicofuncionalizado presente sobre las fibras de polímero hidrofobico.
