摘要： 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 the desired benefits. This invention also relates to a process to produce a wet laid article in a paper mill, said process comprising adding cellulose ester staple fiber to a hydropulper zone, and/or to a refining zone, and/or after the refining zone wherein said paper mill process is not substantially modified to allow for said adding of said cellulose ester

摘要： A wet-laid fibrous product is provided that comprises recycled cellulosic fibers, cellulose ester staple fibers, and residual recycled ink, where the fibrous product has less ink content compared to the ink content for a 100% cellulose comparative fiber wet-laid product, when processed under similar conditions. The wet-laid fibrous product can be formed from a deinked recycled paper pulp slurry, the pulp slurry comprising recycled cellulosic fibers, cellulose ester staple fibers, and ink. A deinking process for the slurry is also provided.

摘要： A process of making a paper or nonwoven article is provide. The process comprising: a) providing a fiber furnish comprising a plurality of fibers and a plurality of binder microfibers, wherein the binder microfibers comprise a water non-dispersible, synthetic polymer; wherein the binder microfibers have a length of less than 25 millimeters and a fineness of less than 0.5 d/f; and wherein the binder microfibers have a melting temperature that is less than the melting temperature of the fibers; b) routing the fiber furnish to a wet-laid nonwoven process to produce at least one wet-laid nonwoven web layer; c) removing water from the wet-laid nonwoven web layer; and d) thermally bonding the wet-laid nonwoven web layer after step (c); wherein the thermal bonding is conducted at a temperature such that the surfaces of the binder microfibers at least partially melt without causing the fibers to melt thereby bonding the binder microfibers to the fibers to produce the paper or nonwoven article.

摘要： A composition is contained a blend zone prior to refining containing non-fibrillated virgin cellulose fibers, waste/recycle cellulose fibers or both; cellulose ester fibers, water, and one or more additives comprising fillers, internal sizing agents, biocides, process anti-foaming agents, colorants, optical modifiers, or a combination thereof. An in-line mixer can be used for adding the additives, and the consistency of the composition is lowered relative to a feed of material from a hydropulper.

摘要： 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.

摘要： 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.
