  • Patent number: 5942288
    Abstract: Described is a fiber glass mat composition comprising a fiber glass matrix bonded with fire retardant melamine resin binder composition capable of forming a nonwoven mat having at least 27% by weight nitrogen (N) in the dry, but uncured resin. Also described is a method of making a fire retardant nonwoven fiber glass mat comprising the steps of providing an aqueous melamine based resin binder; applying the binder to fiber glass; and recovering a fire retardant fiber glass mat, wherein the mat has at least 27% by weight N in the dry, but uncured resin wherein the ratio of resin in the mat to N content of the resin does not exceed about 0.6.

  • Patent number: 5462642
    Abstract: A method of producing a nonwoven fiber glass mat that contains discrete areas which are of different construction than the remainder of the mat. The permeable forming screen onto which a fibrous aqueous slurry is deposited is of a different structure in areas corresponding to the discrete areas of the mat so as to restrict the flow of water through those areas. Less fiber is deposited in those areas, resulting in the discrete areas being comprised of a thinner mat. The orientation of fibers within the discrete areas can be controlled by correlating the restricted flow of slurry in these areas to the flow of slurry necessary to cause this condition.

  • Patent number: 5232745
    Abstract: Described is a method of neutralizing acid containing compositions present in an insulation board comprising the steps of providing an insulation board containing a leachable acid composition and neutralizing the leachable acid by applying to the board an effective neutralizing amount of an inorganic alkali metal or alkaline earth metal salt. Preferably, the board is a phenolic foam having opposing sides of a fiberglass facer with the neutralizing agent embedded in the fiberglass facer.

  • Patent number: 5171238
    Abstract: An absorbent pad, such as a sanitary napkin, is provided having a fibrous facing sheet. The fibrous face is a fractional-denier fibrous nonwoven fabric which may or may not be laminated to a thermoplastic sheet, depending on its strength. The sheet is vacuum perforated to make it permeable to body fluids.

  • Patent number: 5091240
    Abstract: A combination of hot melt and water-based adhesives (solution resin or latex) is particularly advantageous for bonding fibers together to form a layer and for bonding that layer to an adjoining layer. The water-based adhesive, which need not be crosslinkable, provides fiber-to-fiber bonding through the layer of fibers, while the hot melt adhesive bonds the layer of fibers to the adjoining layer. In preferred embodiments, the layer of fibers is moisture absorbent and formed of wood pulp, cotton, rayon, or cellulose triacetate fibers (possibly with the addition of a small amount of thermoplastic fibers to increase bulk); the fibers can be reprocessed fibers of irregular lengths; the water-based adhesive is a latex, non-crosslinkable adhesive; the adjoining layer is permeable to moisture and made of a nonwoven polyolefin, rayon, polyester, or blend thereof; a moisture-barrier layer (e.g.

  • Patent number: 4869782
    Abstract: Anfractuous cellulose fibers exhibiting exceptional high bulking properties are produced by treatment of dry hammermilled wood cellulose fibers with anhydrous liquid ammonia at substantially atmospheric pressure. Fibrous webs of enhanced bulk are produced by preparing an aqueous furnish comprising at least ten percent by weight ammonia treated anfractuous fibers in admixture with conventional papermaking fibers.

  • Patent number: 4822332
    Abstract: An applicator for delivering an object, such as a menstrual tampon, to a cavity, such as the vaginal canal, which applicator is not much longer than the object when delivered to the user, is provided. The applicator is a unitary injection blow-molded device which includes a first tubular section housing the object, a second collapsible and extensible corrugated tubular section abutting the first section, and a third tubular section abutting the second section and serving primarily as a handle. An integral pusher member is formed in the interior of the applicator attached to the inner wall of the third section, and is biased to assume a position along the centerline of the applicator. The applicator is delivered to the user in a collapsed state, with the pusher alongside the object in the first section. The user extends the object by pulling on the first and third sections, withdrawing the pusher from the first section so that it aligns itself behind the center of the object.
