    Abstract: A fiber-reinforced foamed material comprises a foamed body of a resin having a flexural elasticity modulus not smaller than 150 kg/mm , reinforcement fibers, and a bonding component through which the reinforcement fibers are integrated with the foamed body so as to reinforce the foamed body. A method for producing a fiber-reinforced foamed material comprises the steps of: providing a material having a potential foamability; providing a composite fibrous material in the form of composite fibers and/or composite yarns each having a first component and a second component; and allowing the foamable material to foam together with the composite fibers or composite yarns at a temperature 10 DEG C or more higher than the thermal deformation temperature or melting temperature of the first component and 20 DEG C or more lower than the thermal deformation temperature or melting temperature of the second component, whereby the first component is thermally deformed or melted to serve as a bonding component, while the second component remains as a fibrous reinforcement component, the fibrous reinforcement component being integrated with the foamed body through the bonding component so as to reinforce the foamed body.

    Abstract: The present invention relates to an artificial grain leather having different color spot groups comprised of ultra fine fibers, in which at least one side of the fibrous substrate has two types of colors differing in hue and/or lightness value and being covered with transparent resin layers. The present invention produces a three-dimensional surface effect and a grain pattern effect, and is recognized as consisting of a mixture of ultra fine fibers each being quite different in color from the next, though providing the appearance of a single color from a distance, and producing a subdued and rich appearance as a result of the integration of colors by the color of a coating layer.

    Abstract: Sheet-like materials for example for use as synthetic fabrics, comprising a bundle of fine fibers having a maximum deformation ratio of about 12% and a minimum apparent density of 0.21 g/cm3, said fine fibers having a maximum denier of about 0.45 are disclosed. The materials are made by forming a fiber aggregate of multi-component fibers, removing one component from the fibers, eg. by dissolution, to convert each fiber to a bundle of fine fibers consisting of the residual component, shrinking and heat treating the aggregate and impregnating the aggregate with a binder.
