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.

Recycle bale comprising cellulose ester

A bale of sheets made of waste/recycle cellulose fibers and cellulose ester (CE) staple fibers can be fed to a hydropulper. The CE staple fibers have: i. a denier per filament (DPF) of less than 3, or ii. a cut length of less than 6 mm, or iii. crimping, or iv. a combination of any two or more of (i)-(iii). The bales can be fed and dropped in as entire bales to a hydropulper, or a blend tank directly or indirectly in fluid communication with a hydropulper, using the same feed system employed for feeding cellulose to the hydopulper and avoiding having to defiberize by pulling or drawing fibers from a box container into a hydropulper. The waste/recycle cellulose fibers and CE staple fibers can be co-refined prior to making the bale of sheets.

Recycle pulp comprising cellulose acetate

A recycled cellulose pulp composition is provided which comprises recycled cellulosic fibers and cellulose ester staple fibers. A wet-laid fibrous product is also provided which comprises recycled cellulosic fibers and cellulose ester staple fibers. A bailed article is also provided that comprises recycled cellulosic fibers and cellulose ester staple fibers. In embodiments, the recycled cellulosic fibers are present in an amount of 50 wt % or more, based on the total dry weight of fibers, and the cellulose ester staple fibers are present in an amount sufficient to increase the Canadian standard freeness (CSF) of the composition by 5% or more compared to a 100 wt % cellulosic fiber pulp composition processed under similar conditions.

Soft wipe comprising cellulose acetate

A soft wipe article is provided comprising a wet-laid sheet which comprises cellulosic fibers and cellulose ester staple fibers, wherein the cellulose ester staple fibers are present in an amount sufficient to provide the wet laid-sheet with a lower density and higher thickness at a given basis weight compared to a 100% Cellulose Comparative composition, when processed under similar conditions. The cellulose ester staple fibers can also provide the wet laid-sheet with a higher softness, while maintaining or increasing tear strength, compared to a 100% Cellulose Comparative composition, when processed under similar conditions.

The cellulose ester staple fibers can also provide the wet laid-sheet with a higher softness, while maintaining or increasing tear strength, compared to a 100% Cellulose Comparative composition, when processed under similar conditions.

Food packaging articles

Containers and lids made from cellulose fibers and cellulose ester fibers are provided that have enhanced air permeability, stiffness, R-heat insulation values, or thickness at equivalent grammage basis weights are provided, or alternatively, maintaining one or more of these properties while lowering the basis weight of the containers or lids. The container and lids with this synthetic fiber can be biodegradable when made with cellulose ester fibers having a degree of substitution of not more than 2.5. Examples of such containers are food packaging such as hot or cold delivery boxes.

Refining to a desirable freeness

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.
