Provided is a natural leather having a novel coating layer which feels leathery. The coating film retains material properties such as strength and wearing resistance. When the user directly touches the natural leather, the coating layer present on the surface of the natural leather gives slick characteristics of natural leathers and smoothness. The natural leather has a coating film formed on a surface thereof, the coating film including: a color coat layer formed from a mixture of a hard component (10% modulus is more than 2.3 but no more than 3.0) and a soft component (10% modulus is more than 0.0 but no more than 1.0) of a two-component polyurethane resin; and a topcoat layer formed from a mixture of a medium component (resin having a 10% modulus of more than 1.0 but no more than 2.3) and a soft component (resin having a 10% modulus of more than 0.0 but no more than 1.0) of a two-component polyurethane resin.

A hood frame is provided with a center bead, front radiating beads and rear radiating beads to ensure that the front hood bends in the shape of inverted letter-V under a frontal crash load. Further, the beads provide the hood frame with a stiffness (including an out-of-plane stiffness) which is required of the front hood while the downward deformation of the hood frame under a downward load can be controlled and the HIC level can be set at an appropriate level.

Vehicle front hood structure

Provided is an allergen reduction-processing agent capable of giving an allergen reducing effect to a fibrous product while restraining whitening, and chalk marks. As chemical agents having an allergen-restraining effect, a zirconium based compound and a sulfonyl group-containing aromatic compound are used. An aqueous dispersion containing these components is used as an allergen reduction-processing agent for processing a fibrous product. The ratio by weight of the zirconium based compound to the aromatic compound is preferably 1 to 6:0.05 to 1.5.

A hood or trunk lid is a blow-molded article and includes an outer skin and a stiffener integral with the outer skin. The stiffener has a tub-like molded portion which extends in a widthwise direction of a vehicle body and protrudes toward the outer skin. A ridge of the tub-like molded portion is spaced apart from the outer skin, so that the hood or trunk lid is folded from a start point provided by the tub-like molded portion by a shock force from a collision.

A process for the high speed production of fiber reinforced plastic moldings forms several preforms which are solidified with chopped fibers, resin powders and a binder and are held between two preheating plates. Each plate is formed of a thin metal plate and will preheat the preforms to a temperature higher than the melting point of the resin. While the preforms are held between the preheating plates, the preforms are cold-pressed in a mold maintained at a temperature lower than the melting point of the resin for simultaneous impregnation and cooling of the resin. In addition, a preforming mold is placed in a vacuum chamber and precut chopped fibers are positioned in a tank. The preforming mold is placed into the tank and an exhauster is actuated to vacuumize both the vacuum chamber and the preforming mold, thereby adsorbing the chopped fibers in the tank onto the preforming mold and forming on the surface of the preforming mold an unsolidified preform comprising the chopped fibers. Resin powders are sprayed onto the preform for adsorption. A binder is subsequently applied under reduced pressure onto the preform. After drying the preform, the chopped fibers along with the binder are solidified.
