The present invention relates to the fields of fibers and uses thereof such as for producing fiber webs, such as paper, board or tissue. Specifically, the invention relates to a method of monitoring and controlling cellulolytic activity in an aqueous cellulose fiber suspension or process water for a production method of a fibrous web containing cellulose fibers. Also, the present invention relates to a method of manufacturing a fibrous web, such as a paper, board, tissue or the like, and use of a biocide for controlling cellulolytic activity in an aqueous cellulose fiber suspension or in process water e.g. for a production method of a fibrous web containing cellulose fibers. Still, the present invention relates to a fibrous web, such as a paper, board, tissue or the like, an aqueous cellulose fiber suspension or process water for a production method of a fibrous web containing cellulose fibers, and a system for controlling cellulolytic activity in an aqueous fiber suspension or in process water.

The present disclosure relates to a smoking article including biodegradable cigarette paper.

An object of the present invention is to provide a print product which has a printed region where printing with ultraviolet laser is applied and which is excellent in viewability, a method for producing a print product by irradiation with ultraviolet laser, and a printing medium for laser printing, for use in the print product and the method for producing a print product. The print product of the present invention has a printed region comprising discolored titanium oxide in at least one portion of a sheet medium selected from the group consisting of paper or a film having a printable region comprising titanium oxide; titanium oxide is filled in the sheet medium; a titanium oxide content in the printable region in the sheet medium is 1.0% by mass or more, pulp constituting the paper has a length-weighted average fiber length and an average fiber width in specified ranges, and the paper has a basis weight of 20 g/m.sup.2 or more, when the sheet medium is the paper; a titanium oxide content in the printable region in the sheet medium is 0.3% by mass or more, the film has a thickness of 15 μm or more, and a resin constituting the film comprises a specified resin, when the sheet medium is the film; and a ratio between a Raman intensity assigned to titanium oxide in the printed region and a Raman intensity assigned to titanium oxide in a non-printed region is 0.70 or less.

The present disclosure describes methods of treating cellulosic materials with compositions that allow greater retention of inorganic particles on cellulosic substrates. The methods as disclosed provide combining saccharide fatty acid esters (SFAE) with such inorganic particles and applying such combinations on cellulosic materials to eliminate or reduce the use of retention aids or binders for filler in the paper making process. Compositions comprising such combinations of SFAE and inorganic particles are also disclosed.

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.

The present disclosure provides novel paper sheet mulch products having benefits over prior sheet mulches, which may include brown or recycled fibers, as well as additives, such as opacity, water-resistant, and strength additives, resulting in mulch products with an improved combination of basis weight, stretch, strength, opacity, and/or water-resistance characteristics.

A composition for addition to a ceiling tile, flooring product, or other construction product may include microfibrillated cellulose and optionally an inorganic particulate material. The ceiling tile, flooring product, or other construction product may further include perlite, mineral wool, wood pulp, starch and other additives, where the wood pulp and other inorganic particulate materials are bonded to the microfibrillated cellulose. Methods of manufacturing the compound are also disclosed.
