用于液体过滤介质的原纤化纤维

Fibrillated fibers for liquid filtration media

Abstract

Fiber webs which are used in filter media are described herein. In some embodiments, the fiber webs include fibrillated fibers and optionally non-fibrillated fibers, amongst other optional components (e.g., binder resin). In some embodiments, the fiber webs include limited amounts of, or no, glass fiber. The respective characteristics and amounts of the fibrillated fibers are selected to impart desirable properties including mechanical properties and filtration properties (e.g., dust holding capacity and efficiency), amongst other benefits.
本申请中描述了用于过滤介质的纤维网。在一些实施方案中,纤维网包含原纤化纤维和任选的非原纤化纤维以及其他任选的组分(例如,粘结剂树脂)。在一些实施方案中,纤维网包含有限量的玻璃纤维或不包含玻璃纤维。对原纤化纤维的各个特征和量进行选择以赋予期望性质,包括机械特性和过滤特性(例如,容尘量和效率)以及其他益处。
