Abstract
The compositions and methods that can be used in desiccants in manufactured units requiring an enclosed atmosphere with minimal water and volatile content. Such materials need to maintain a low concentration of volatile materials in an enclosed space in a unit to avoid any unneeded interference of water or other volatiles in the utility of the unit. In one application, the desiccant material can keep the insulated glass units (IGUs) from fogging, which includes forming water or depositing volatiles on internal surfaces.
Claims22
1-32. (canceled)
A web comprising a fiber layer that comprises biocomponent fiber, and a particulate comprising a polymer and a desiccant particulate;
- wherein substantially each particle is bonded to a bicomponent fiber of the fiber layer.
A method of making a desiccant web comprising;
- (1) compounding a polymer and a desiccant particulate composition,
- (2) airlaying a bicomponent fiber and the polymer and particulate composition;
- and
- (3) fusing the polymer and particulate composition and the bicomponent fiber, thereby forming the desiccant web.
