  • Patent number: 5047288
    Abstract: Provided is a moldable sheet comprising a synthetic organic fiber nonwoven fabric for reinforcing resinous molded article and a resin composition having impregnated the nonwoven fabric. The nonwoven fabric comprises opened single filaments having a specific fineness and bundles of filaments laid parallel with one another having a specific total fineness distribution, said single filaments and said bundles of filaments being bonded with a binder of non-fiber form. By employing this construction, the nonwoven fabric can, when used for reinforcing resinous article, improve the impact resistance, i.e. falling ball impact resistance and Izod impact resistance, which have been poor with conventional glass-fiber reinforced resinous shaped articles, while maintaining the high mechanical strength of the resinous article.

  • Patent number: 4594283
    Abstract: There is provided a shoemaking material which comprises a laminate of two webs having different apparent densities. One web has an apparent density lower than 0.4 g/cm.sup.3, and the other web has an apparent density higher than 0.3 g/cm.sup.3, with their difference being greater than 0.1 g/cm.sup.3, preferably greater than 0.3 g/cm.sup.3. The laminate has a weight of 200 to 1500 g/m.sup.2. The shoemaking material of such structure has a soft face layer which provides cushioning properties and a hard core layer which keeps the shape of a shoe. Because of this unique structure, it permits moisture to pass through and dry rapidly. Thus it keeps shoes in good sanitary condition and makes shoes more functional.
