Abstract: An expansion-molded article which not only is lightweight and has excellent sound-absorbing properties but is excellent in surface properties and mechanical strength; a web and stampable sheet suitable for use in producing the expansion-molded article; and a process for producing these. The process comprises: evenly dispersing reinforcing fibers, a thermoplastic resin, and heat-expansible particles in a surfactant-containing aqueous medium containing fine bubbles to prepare a frothy liquid; forming this frothy liquid into a web by a papermaking method; subsequently heating, pressing, and cooling the web to form a stampable sheet; heating the stampable sheet to expand the heat-expansible particles; and molding and then cooling the sheet to produce an expansion-molded article of the stampable sheet. In the web formation by a papermaking method, defoaming is conducted by suction to cause the heat-expansible particles to be present on either side of the web in a higher density, whereby the heat-expansible particles are caused to be present in either side of the expansion-molded article in a higher density.

Abstract: In a method for producing foamed moldings as a product wherein a fibrous material and an aqueous solution are kneaded, the kneaded product is foamed and the foamed product is molded into a predetermined shape, followed by drying, the improvement which comprises using, as said solution, an aqueous solution containing a binder dissolved therein having a gelatin and/or a glue of a jelly strength of 130 Bloom or more as a main component. The method allows the prevention of the formation of depressions in a poekmark form on the surface of the foamed moldings, which leads to the improvement of the yield of the product, and also the production of a product having a reduced specific gravity, and thus can be employed for producing foamed moldings such as a cushioning material excellent in elastic performances continuously, economically, and on a large scale.

Abstract: A nonwoven web of fibrous material is made by the foam process using a manifold of a particular construction. The manifold has a casing with first and second opposite ends including an inlet for a foam-fiber-surfactant slurry at the first end, and optionally a valved outlet at the second end. A center section of the manifold casing has a (e.g. rectangular) cross-section that becomes smaller moving from an inlet toward the outlet. First and second substantially closed side walls, a porous front wall having an effective length, and a back wall opposite the front wall, are provided for the center section, the walls planar or curved. Any suitable structures are provided for introducing a second (e.g. substantially fiber-free, or a fiber-foam slurry) foam into the center section through the back wall. Pressure sensors penetrating one or both of the side walls may sense the pressure within the center section, and automatically control the introduction of slurry into the inlet, withdrawal through the outlet, and/or introduction of the second foam into/through the back wall, so as to maintain the basis weight of the foam-fiber slurry passing through the front wall substantially constant along the effective length of the front wall.

Abstract: Method for the manufacture of low density mineral wool structure panels by frothing a dilute aqueous dispersion of mineral wool, lightweight aggregate, binder and a small amount of amine-based cationic surfactant onto a non-woven scrim cover sheet (43). The resultant froth, a mass of very well formed, uniform bubbles, are of a nature that rapidly dewater and burst to concentrate the solids in the mass. The bubbles are readily broken without loss of the uniformly voided structural configuration by a first application of brief pulses of high vacuum followed by further dewatering under vaccum and rapid drying by passing high volumes of heated air through the voided mass without collapse of the structure to result in lightweight structural mineral wool panels.

Abstract: The present invention relates to a nonwoven web comprised of metal or refractory fibers with poly(phenylene sulfide) as a binder. The nonwoven web is prepared by forming a foam furnish by agitating the fibers in a foamed medium, and passing the foam furnish onto a screen and defoaming the furnish. It is preferred that the poly(phenylene sulfide) binder is added to the foam furnish in the form of fibers. Once the furnish is defoamed to form a nonwoven web, the sheet is heated at a temperature sufficient to melt the poly(phenylene sulfide) binder.
