Abstract:
Disclosed is coated paper having a coating structure in which styrene-butadiene latex distribution of a paper coating layer is controlled in order to reduce fold cracking of the coated paper and a method for manufacturing the same. The coated paper in which different types of latexes are separately applied to two coating layers exhibits considerably improved stiffness and reduced fold crack, as compared to the existing coated paper.
Abstract:
Various embodiments directed towards methods of applying sizing to fibers are disclosed herein. In some embodiments, solvent can be used to dissolve a sizing material into a solution, which can then be used to coat the fibers. In some embodiments, a water bath is used to coagulate a sizing on the fiber surface and to remove the remove solvent after coating the fibers, so that water vapor can be created during a subsequent drying step as opposed to solvent vapors. In some embodiments, strong acids or strong bases can be used as the solvent.

Abstract:
Provided are a method and an apparatus for the application of a flowable composition to fiber webs or mats, particularly oriented fiber mats, that suppresses the disruption of the fibers within the fiber mat that may result from turbulent flow in and near the point at which the flowable composition contacts the fiber mat. The apparatus includes a conveyor configured to pass through and be supported by a flood pan that allows the flowable composition to accumulate and move with the fiber mat in a machine direction in order to submerge or saturate the fiber mat as it passes through the flood pan. The apparatus also includes a recess provided in the flood pan substantially below an impact zone for redirecting the flowable composition while suppressing turbulent flow and counter-current flow within the flowable composition.
Abstract:
Coating compositions including about 50-80% by weight of a water-based silicone elastomer composition, about 0.5-4.0% by weight of a silane adhesion promoter, about 0.02-0.5% by weight of a silicone surfactant, and about 10-50% by weight water are disclosed herein. Also included are methods of preparing the coating compositions and methods of using the coating compositions.
Abstract:
Disclosed are a multilayer coating film made from a natural material and a method of producing the same. The multilayer coating film may be produced by forming a multilayer coating film through formation of a color coating film for providing adhesion and color to a cork on the cork material and a clear coating film for realizing texture and supplementing properties on the color coating film. As such, the multilayer coating film may be made from a natural material to diversify the color and gloss of cork as a natural material, to additionally increase marketability of an interior material and provide various appearance, to prevent discoloration due to light (e.g. UV light.) and water permeation, and to enhance durability against abrasion, scratches and the like.
Abstract:
Reflectin proteins are proteins derived from cephalopods (certain species of squid) which have unusual optical properties. Disclosed herein are thin films of reflectin proteins which can be tuned to reflect infrared light. Advantageously, the films can be tuned dynamically over short time scales, to reflect at different wavelengths. Disclosed herein are novel infrared-reflective coatings, methods of making such coatings, and infrared-reflective objects such as textiles, building materials, and camouflage materials.
Abstract:
A method of manufacturing a composite film, the method including: preparing a coating liquid including a resin and a filler and having a viscosity of from 0.1 Pa·s to 5.0 Pa·s: removing aggregates contained in the coating liquid by making the coating liquid pass through a filter having a minimum pore diameter that is larger than a maximum particle diameter of the aggregates; applying the coating liquid that has been subjected to the aggregate removal on one surface or both surfaces of a porous substrate, to form a coating layer; and solidifying the resin contained in the coating layer, to obtain a composite film including: the porous substrate; and a porous layer that is formed on one surface or both surfaces of the porous substrate and that contains the resin and the filler.
Abstract:
A composite fiber may include at least one reinforcing filament formed of a first material. A second material maybe systematically deposited in a printed onto the at least one reinforcing filament such that at least one of a length, a width, and a thickness of the second material varies across a surface of the at least one reinforcing filament. The printed pattern may alter one or more properties of a composite structure containing the composite fiber.
