超微細粉末又はナノサイズ粉末を組み込んだ不織媒体

摘要

The invention is a fibrous structure for fluid streams that is a mixture of nano alumina fibers and second fibers arranged in a matrix to create asymmetrical pores and to which fine, ultrafine, or nanosize particles such as powdered activated carbon are attached without the use of binders. The fibrous structure containing powdered activated carbon intercepts contaminants from fluid streams. The invention is also a method of manufacturing and using the fibrous structure.
