COMPOSITION OF MATTER IN A POST-REFINER BLEND ZONE

After cellulose fibers and cellulose ester fibers are co-refined, they are fed to a blend tank continuously feeds a wet laid process. The composition in the blend tank includes co-refined cellulose fibers and cellulose ester fibers and one or more additives, and the cellulose ester fibers have a denier per filament (DPF) of less than 3, a cut length of less than 6 mm, crimped, or non-round with a DPF of less than 3.

BROKE COMPOSITION OF MATTER

Broke pulp in a paper making process is obtained by pulping broke, and the broke pulp is made of fibrillated cellulose fibers and cellulose ester (CE) staple fibers having a denier per filament (DPF) of less than 3, or a cut length of less than 6 mm, or crimped, or non-round with a DPF of less than 3. The broke pulp can be added to the stock preparation zone of a wet laid manufacturing facility and fed through a refiner.

PAPER COMPOSITION CELLULOSE AND CELLULOSE ESTER FOR IMPROVED TEXTURING

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 composition, process, wet laid product, or articles exhibiting any one of many desired benefits. The invention also relates to a composition comprising cellulose fiber and a staple fiber exhibiting improved texturing.

WASTE RECYCLE COMPOSITION

A recycled cellulose pulp composition is provided which comprises recycled cellulosic fibers and cellulose ester staple fibers. The recycled cellulose pulp containing co-refined re-cycled cellulose fibers and cellulose ester staple fibers can be added to a hydropulper and fed back through a refiner to make wet laid products.
