Method for producing sheet containing fine fibers

The present invention was accomplished in order to provide a method for producing a sheet containing fine fibers, which enables production of a sheet containing fine fibers without producing wrinkles. The present invention provides a method for producing a sheet containing fine fibers comprising a coating step of coating a dispersion containing fine fibers having a fiber diameter of 1000 nm or smaller on a base material, and a drying step of drying the dispersion containing fine fibers coated on the base material to form a sheet containing fine fibers.

Coating compositions comprising ground natural calcium carbonate (GCC)

The present invention relates to a coating composition comprising at least one binder and at least one ground natural calcium carbonate material. The invention further relates to the use of at least one ground natural calcium carbonate material in a coating composition comprising at least one binder as well as to an article that is coated with such a coating composition and a paint comprising such a coating composition.

ARTICLES FORMED OF PULP BASE MATERIALS WITH MODULATED SCENT RELEASE
20230158195 · 2023-05-25 · ·

Described are articles formed of a pulp base material comprising fibers, wherein pores are formed between the fibers. A volatile composition with at least one top note component and at least one base note component at least partially fills the pores of the pulp base material. A release rate of the at least one top note component is modulated by the pulp base material, and a release rate of the at least one base note component is enhanced by the pulp base material.

Water-dispersible sheet

A water-dispersible sheet is described that maintains water dispersibility while providing suppressed time degradation of the tacky adhesiveness of a tacky adhesive layer. The water-dispersible sheet has a paper substrate with a multilayer structure. One layer of the multilayer structure is an inner layer that is not in contact with the tacky adhesive layer. Another layer is a surface layer that is in contact with the tacky adhesive layer. The layers independently include mixed pulps of a wood pulp and a refined pulp with an α-cellulose content of 88 % by weight or more. The weight ratio of the layers and the beating degree of the mixed pulps are set in the specific ranges.

Fiber body forming method and fiber body forming apparatus

A method of forming a fiber body includes defibrating a raw material in air to provide fibers; depositing the fibers in air onto a belt; applying pressure to the deposited fibers to form a pressurized web; and applying a liquid containing an additive to two surfaces of the pressurized web.

SYSTEM AND METHOD FOR REPRINTING ON PAPER
20170335518 · 2017-11-23 · ·

An enhanced paper for printing, including a substrate, an ablation resistant coating applied to the substrate, wherein the enhanced paper is ablation resistant so that it is not damaged by a light beam that illuminates enhanced paper with a fluence that ablates ink or toner but would damage standard printing paper that is made from cellulose fiber and is non-ablation resistant; and wherein the enhanced paper has physical properties of the standard printing paper for printing with laser printers and ink printers.

Grease, oil, and water resistant coating compositions

Described herein are coatings which impart oil, grease, and water resistance to various materials, such as paper, paperboard and polymeric materials. Such coatings may be applied as barrier coatings to the substrate materials in order to inhibit and prevent the transmission of oil, grease and water; that is, to prevent oil, water grease from passing into and/or through the substrate material. The coatings include an acrylic-based polymer latex, a styrene-butadiene rubber latex, a styrene-acrylic resin solution, a large particle size wax, and optionally, a small particle size wax. Also disclosed herein is a process of preparing the coatings. Also disclosed are products to which the coatings have been applied in order to impart oil, grease and/or water resistance, and processes for preparing such products.
