This invention relates to a paper friction material and a method of manufacturing the same, wherein the paper friction material is configured such that dispersibility and bondability are increased between a filler and a matrix. The paper friction material which is suitable for use in a vehicle, includes a friction base including pulp and a coating layer formed on the friction base using a mixture of latex and a functional material. The OH reactive group of the pulp and the aromatic ring of the latex are hydrogen-bonded so that the friction base and the coating layer are coupled with each other.

The present invention is directed to products, such as paper and paperboard products, comprising a substrate containing cellulose and top ply comprising microfibrillated cellulose and inorganic particulate, to methods of making such paper and paperboard products, and associated uses of such paper and paperboard products. The microfibrillated cellulose and inorganic particulate material are applied at the stage when the wet substrate is in the process of being formed on the wire of a papermaking machine, thereby avoiding the additional cost of more extensive equipment and machinery as well as in separate drying of a coating. The microfibrillated cellulose facilitates the application of inorganic particulate onto the surface of a wet paper or paperboard substrate when applied thusly, by trapping the inorganic particulate on the surface of the substrate and by giving the composite sufficient strength and a suitable pore structure to make it suitable for printing and other end-use demands.

A paper device for coloring, highlighting, lowlighting and lightening hair that includes a pad having a plurality of sheets of water dissolvable and biodegradable paper wherein each sheet of paper has a first surface and a second surface; a plurality of colors, a lightener, highlighting agent or low lighting agent on the first surface; an inhibitor on the first surface; a coating of silicone on the second surface to prevent the bleeding of color through the sheet; and a water soluble adhesive strip on the second surface for securing the sheet on a client's hair. Each sheet may also have a heat seal coating applied to either surface that allows the sheet to be made into a dissolvable pouch, cone, corkscrew or other desirable shape. The colors may be used in organic or inorganic dyes, hennas, colors, stains or lighteners and may be infused, coated, imbibed or applied to the sheet using a tint brush or spray.

In an apparatus for raising chickens from hatchlings including a barn having a floor and walls there is provided a plurality of rows of feed stations arranged at spaced positions across the floor each with a feed supply line connected along the row for dispensing feed to each of the feed stations and a plurality of rows of water supply stations each with a water supply line connected along the row for dispensing water to each of the water supply stations where rows of stations are connected to a lift system for raising the stations from the floor. A first strip of biodegradable paper sheet is unrolled along the floor of the barn underneath the row of feed stations and a second strip of biodegradable paper sheet unrolled along the floor of the barn underneath the row of water supply stations where the biodegradable paper is colored with a color selected to be attractive to hatchlings, typically red.
