摘要： 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.

摘要： Dry processing of cellulose fibers in an attritor mill produces small cellulose particles with properties useful for increasing the bulk of paperboard products. In contrast with the usual behaviour of small particles, the dry attritor-processed particles exhibit a further benefit of good drainage on a paper machine. Comparisons are made for the modulus, smoothness, and density of paperboard made with and without the dry-attrited cellulose particles.

摘要： The invention relates to a method for modifying nanofibrillar cellulose composition, comprising—preparing fibrous dispersion of ionically charged nanofibrillar cellulose (NFC), and—applying heat treatment at a temperature of at least 90° C. to the fibrous dispersion until the viscosity of NFC starts to decrease. The viscosity of the heat-treated NFC is reversible by applying shear forces to the NFC.
