11559183 · 2023-01-24 · ·

A wet sheet for cleaning includes multiple layers and is impregnated with a chemical solution. The wet sheet includes hydrophobic fiber layers arranged in a front surface layer and a back surface layer, and a hydrophilic fiber layer arranged in an intermediate layer. The hydrophobic fiber layers have an interlaced part with a high fiber density where the hydrophobic fiber layers are interlaced with the hydrophilic fiber layer. The interlaced part has at least one slightly interlaced part and at least one highly interlaced part which is formed in a dent shape and which is interlaced with a higher fiber density. The highly interlaced part is formed in an area ratio of 10 to 20% to an area of the front surface layer or the back surface layer. Static friction resistance of the wet sheet for cleaning is lower than kinetic friction resistance of the wet sheet for cleaning.

METHOD OF FORMING BIODEGRAD ABFE NONWOVEN FABRIC, NONWOVEN FABRIC OBTAINED BY THIS METHOD, AND SYSTEM OF DEVICES FOR CARRYING OUT THIS METHOD
20230202135 · 2023-06-29 ·

The invention relates to a method of forming a biodegradable nonwoven fabric, the nonwoven fabric obtained by this method, and a system of devices for carrying out this method, to be used for the manufacture of cellulosic articles for clean-up work and sanitary products, and medical uses.

NONWOVEN-FABRIC STRUCTURE AND MANUFACTURING METHOD THEREFOR

A nonwoven fabric structure according to the present invention is a nonwoven fabric structure comprising a long-fiber nonwoven fabric as a main constituent, wherein the nonwoven fabric structure has a basis weight of 250 to 2000 g/m.sup.2, a Frazier permeability of 0 to 20 cc/cm.sup.2.Math.s, and an apparent density of 0.5 to 1.3 g/cm.sup.3, and therefore has excellent shaping properties and excellent mechanical strength properties.

Cleaning sheet

This cleaning sheet is provided with an embossed part in which the sheet is compressed in the thickness direction. The cleaning sheet is provided with outer layers, forming the surfaces of the sheet; and an inner layer sandwiched between the outer layers. In the boundary areas between the outer layers, and the inner layer, the fibers of the layers are entangled. This allows for a sheet that better retains the raised and sunken shapes embossed therethrough and exhibits excellent collecting performance.

COMPOSITE HAVING IMPROVED IN-PLANE PERMEABILITY AND ABSORBENT ARTICLE HAVING IMPROVED FLUID MANAGEMENT

The present disclosure features a composite fabric, including a nonwoven layer including polymeric fibers and/or filaments; a crosslinked cellulose layer including crosslinked cellulose fibers; wherein the crosslinked cellulose layer is positioned opposed to the nonwoven layer (e.g., without an intervening layer different from the crosslinked cellulose layer and the nonwoven layer; in some embodiments, the crosslinked cellulose layer is immediately adjacent to the nonwoven layer); and an interfacial region between the nonwoven layer and the crosslinked cellulose layer, the interfacial region including physically entangled polymeric fibers and/or filaments from the nonwoven layer and crosslinked cellulose fibers from the crosslinked cellulose layer. The nonwoven layer and the crosslinked cellulose layer of the composite fabric are mechanically inseparable in a dry state.

SYSTEM AND METHOD FOR PRODUCING A SINGLE- OR MULTI-LAYER NONWOVEN

The invention relates to an installation and to a method of producing a web, wherein the installation includes a device for producing a layer of wet laid fibres, which has an entangling device and at least one dryer disposed downstream in material transport direction.

Multilayered nonwoven fabric containing submicron fibers, a method of manufacture, an apparatus, and articles made from multilayered nonwoven fabrics
20220025560 · 2022-01-27 ·

This document presents a novel method of manufacturing multilayered nonwoven fabrics consisting of submicron fibers, hydroentangled, meltfibrillated, and/or spunlaid web layers. The composite multilayered webs contain one or more submicron fiber webs placed between inner and outer layers of hydroentangled, meltfibrillated, and/or spunlaid web, forming a fabric that may be utilized in the manufacture of articles which serve as barriers, wipes or sorbent materials, or may have other potential applications. The created novel composite multilayered fabric may have increased loft, softness and bending length, may not be solely dependent upon an electrostatic charge to repel small particles and microbes, and may be formed from a broad selection of natural, synthetic, and recycled polymers, including petroleum- and plant-based, allowing polymer selection based on article lifecycle.
