    • A glass or pretreated meltblown fiber having a cationically charged coating thereon, the coating including a functionalized cationically charged, silicon containing carbohydrate polymer crosslinkable by heat, in which the functionalized cationic polymer has been crosslinked by heat after being coated onto the glass fiber. Also provided is a fibrous filter including a fibrous filter media having a cationically charged coating thereon, the coating including a functionalized cationic polymer crosslinkable by heat, in which the functionalized cationic polymer has been crosslinked by heat after being coated onto the fibers. Further provided is a method of preparing a fibrous filter. The method involves providing a fibrous filter which includes glass fibers or pretreated nonwoven fibers, passing a solution of a functionalized cationic starch polymer crosslinkable by heat through a fibrous filter under conditions sufficient to substantially coat the fibers with the functionalized cationic polymer, and treating the resulting coated fibrous filter with heat at a temperature and for a time sufficient to crosslink the functionalized cationic polymer present on the glass fibers.
    • 一种玻璃或预处理的熔喷纤维,其上具有阳离子电荷的涂层,该涂层包括通过加热可交联的功能化阳离子电荷的含硅碳水化合物聚合物,其中官能化阳离子聚合物在被涂覆到玻璃纤维上之后通过热交联。 还提供了一种纤维过滤器,其包括其上具有阳离子电荷的涂层的纤维过滤介质,该涂层包括通过加热可交联的官能化阳离子聚合物,其中官能化阳离子聚合物在被涂覆在纤维上之后已被热交联。 进一步提供一种制备纤维过滤器的方法。 该方法包括提供纤维过滤器,其包括玻璃纤维或经预处理的非织造纤维,使官能化的阳离子淀粉聚合物的溶液通过热可交联的纤维过滤器在足以基本上用官能化阳离子聚合物涂覆纤维的条件下进行处理, 在足以使存在于玻璃纤维上的官能化阳离子聚合物交联的温度和时间下加热涂布纤维过滤器。
