A fiber mat includes a unitary assembly of fibers including at least a first set of fibers and at least a first binder comprising an organic resin, wherein the unitary assembly of fibers includes a minority portion and a majority portion different than the minority portion, wherein the fiber mat provides at least a 5% increase in tear when placed in a bituminous roofing product compared to an equivalent bituminous roofing product made with a fiber mat of equivalent weight containing a homogenous mat structure.
SKIN MATERIAL AND METHOD FOR PRODUCING SKIN MATERIAL
A skin material containing, in the following order: a base fabric that is configured to contain fibers having a synthetic resin coating layer, wherein fibers adjacent to each other in the base fabric are at least partially fused with each other; and an adhesive layer and a skin layer, which are provided at a surface of at least one side of the base fabric in this order from the base fabric, the skin material having a plurality of ventilation holes passing through the skin material in a thickness direction.
METHOD FOR MANUFACTURING SHEET-LIKE PRODUCT
Provided is a production method in which a sheet-like article that has high moist heat resistance and has good surface quality and texture can be produced, regardless of the coagulation technique used for the polyurethane, by an environmentally friendly manufacturing process that is designed to cause reaction of a crosslinking agent while maintaining the texture possessed by the material before crosslinking. The production method for sheet-like articles is a sheet-like article production method characterized by impregnating a fibrous base material with water dispersed polyurethane as a binder, coagulating it to provide a sheet, adding a solution or dispersion liquid of a crosslinking agent to the sheet, and then heating it at a temperature of 100° C. or more and 200° C. or less.
METHOD FOR MANUFACTURING POLYESTER FABRIC FOR AIRBAG
Disclosed is a method for manufacturing a polyester fabric for an airbag that can not only prevent or minimize the separation of a sizing agent, which is provided to a yarn through a sizing process, during a weaving process, but can also maximize a peel strength between a textile substrate and a coating layer to be subsequently formed thereon and lower the stiffness of an airbag fabric by effectively removing the sizing agent from the textile substrate after the weaving process is completed. The method of the present invention comprises: applying a polyester-based sizing agent to a polyester yarn; manufacturing a textile substrate with the sizing agent-applied polyester yarn; removing the sizing agent from the textile substrate under an alkaline condition of pH 8 to 10; and forming a coating layer on the sizing agent-removed textile substrate in order to enhance air-tightness.
ARTIFICIAL LEATHER FOR CRASH PADS AND CRASH PADS MANUFACTURED USING THE SAME
Disclosed are an artificial leather for crash pads and a crash pad manufactured using the same. The artificial leather for crash pads may have improved workability when workers directly cover a crash pad with the artificial leather for crash pads and require reduced manufacturing costs by using a textile substrate layer made of a circular knit fabric that satisfies a specific physical property range.
