A sheet manufacturing apparatus has a manufacturing unit that makes a sheet; and a plurality of supply units that supply loaded feedstock to the manufacturing unit; and the feedstocks supplied from the plural supply units are conveyed overlapping each other.

The invention relates to the use of a lyocell fiber (1) for the manufacture of a nonwoven fiber fleece (10, 100). To manufacture a thin nonwoven fiber fleece with sufficient mechanical properties, the use of a lyocell fiber is proposed, where the fiber (1) has a cross-sectional aspect ratio of at least 1.8.

The invention further relates to a nonwoven fiber fleece (10, 100). In order to manufacture a thin nonwoven fiber fleece (10, 100) suitable for use as a battery separator, it is proposed, that the fiber fleece comprises at least two layers (11, 12) of fibrillated lyocell fibers (13), with the fibrillated lyocell fibers (13) having solid cores (14, 110) and fibrils (15) protruding from said cores (14), the fibers and fibrils (15) being intermingled to form the fiber fleece (10), embedding the solid cores (14) therein, whereby the solid cores (14, 110) of the fibrillated lyocell fibers (13) have an average cross-sectional aspect ratio k of at least 1.5.

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.

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.

Nonwoven materials having low dust or lint content and methods of making the same are provided. Such nonwoven materials can include cellulose fibers pre-treated with a plasticizer or include the addition of plasticizer during the process of forming the material.

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.

A water-dispersible composite structure, which comprises one or more layers, and a method of producing the same. At least a part of the layers is formed by a fibrous web or sheet containing 50-90 parts by weight of wood fibers and 10-90 parts by weight of annual or perennial plant fibers and/or 10-50 parts by weight of synthetic short-cut fibers, and 0.1-20% by weight of a binder, calculated from the weight of the fibers, and at least a part of the binder being a water-soluble polymer and another part a water dispersible binder, and the fibrous sheet or web being produced by wet forming. By means of the invention, the fibers of the composite structure can be recovered and recycled by equipment conventionally used in the paper and paperboard industry.

The present disclosure relates to relates to fibers, yarns, fabrics and other materials that interact with electromagnetic radiation, wherein these materials are made from a carrier material (such as a cellulose or semi-cellulose) and a plurality of mineral particles as well as methods of making these materials. Specifically, the materials interact with electromagnetic radiation by absorption, reflection, refraction, polarization, or wavelength shifting. The fibers, yarns, fabrics and other materials of the disclosure are useful in a variety of products including furniture upholstery, sportswear and fashion applications.
