Particle-containing fibrous web |
摘要 |
A porous sheet article comprising a self-supporting nonwoven web of polymeric fibers and at least 80 weight percent sorbent particles enmeshed in the web, the fibers having sufficiently greater elasticity or sufficiently greater crystallization shrinkage than similar caliper polypropylene fibers and the sorbent particles being sufficiently evenly distributed in the web so that the web has an Adsorption Factor A of at least 1.6x104/mm water. The articles have low pressure drop and can provide filter elements having long service life and an Adsorption Factor approaching and in some instances exceeding that of a packed carbon bed. |
