    Abstract: The present invention provides compositions comprising cellulose fibers and cellulose ester fibers and wet laid articles made from the compositions, as well as wet laid processes to produce these compositions. More specifically, the present invention provided compositions comprising cellulose fibers and cellulose acetate fibers and wet laid articles made from these compositions as well as wet laid processes to produce these compositions. The present invention also relates to developing a composition, process, wet laid product, or articles exhibiting any one of many desired benefits. Specifically, a wet laid process comprising a process that allows the quantity of water removed from a web passed through press rolls is increased relative to a web made from a 100% cellulose comparative composition or any composition without cellulose ester staple fibers co-refined with cellulose at the same press loading

    Abstract: A sensible and latent heat exchange or adsorbent media formed from an improved desiccant or adsorbent paper having higher strength and thinner gauge to provide increased area of media, the media having a multiplicity of passageways therethrough through which an air stream can flow. The improved desiccant or adsorbent paper is comprised of fibrillated organic fibers formed to provide an improved support material having improved levels of strength and higher levels of desiccant or adsorbent material contained in the improved fibrous support material to provide the improved paper. The improved desiccant paper is capable of adsorbing or transferring sensible heat from a warm air stream and releasing or transferring the absorbed sensible heat into a cool air stream as the air stream flows though the sensible and latent heat exchange media. Further, the desiccant or adsorbent material is capable of adsorbing moisture from a humid air stream flowing through the sensible and latent heat exchange media and capable of releasing the adsorbed moisture into a dry air stream flowing through the passageways of the sensible and latent heat exchange media.

    Abstract: A composition of paper comprising 99 to 10 weight percent cellulose fibers and 1 to 90 weight percent cored cellulose fibers that are uniformly dispersed within the paper. The cored cellulose fibers are composed of a cellulose sheath that is 4 to 15 weight percent of the weight of the fiber and a cellulose acetate core. The cored cellulose fibers contain no substantial crimp and have an average length of 1 to 7 mm, a density of 1.20 to about 1.35 gm/cc, a denier 1 to 30 grams per 9,000 meters and a uniform dispersion index of less than 0.15.
