Abstract
A filtration structure comprising a thermally bonded, wet laid, fibrous web and support is provided. The web is formed from bicomponent fiber comprising a structure-forming component and a heat-bondable component. Also provided is a filtration method using the filtration structure. Beneficially, the filtration structure may include microfiber.
Claims7
A filtration structure comprising a thermally bonded, wet laid, fibrous web, and a suitable filtration support structure;
- said fibrous web being formed from bicomponent fiber comprising a web structure-forming core component and a heat-bondable sheath component.
A filtration method comprising passing a particulate-containing fluid through a thermally bonded, wet laid fibrous web formed from bicomponent fiber comprising a web structure forming core component and a heat-bondable sheath component;
- said wet laid, fibrous web is supported on a suitable filtration support structure.
A filtration structure comprising a thermally bonded, wet laid, heterofiber matrix, said heterofiber matrix being formed from bicomponent fiber comprising a structure-forming core component and a heat-bondable sheath component, and from microfiber having a diameter of less than about 2 microns;
- said wet laid heterofiber matrix is supported on a suitable filtration support.
