  • Patent number: 8839496
    Abstract: A fire blocking non-woven textile containing a first carded web of char-forming fibers containing aramid or melamine/formaldehyde fiber and a second carded web of oxygen-depleting fibers comprising a blend of polyacrylonitrile copolymer with a halogen comonomer and a polyester polymer. The webs may be needled-punched or thermally bonded and remain as separate layers separating the action of the char forming and oxygen depleting layers to optimize char strength, provide a light weight product, which may satisfy 16 CFR 1633 at thicknesses of up to 3.0 mm.

  • Publication number: 20100011562
    Abstract: In a first embodiment, the present disclosure is directed at a non-woven fabric, which provides, at selected locations, the ability to mechanically and releasably join with a hook fastener. The non-woven web may include entangled fibers which have been overprinted with dots, lines or designs to create defined locations of joined fibers which may engage with a corresponding hook profile. The print material may include thermoplastic and thermoset binder systems. The binder systems may include a gas expanding substrate (e.g. gas-filled microspheres) which may provide a relatively thicker location for joining with the corresponding hook engaging material.

  • Publication number: 20080313873
    Abstract: The present disclosure relates to a highloft needlepunched fabric wherein said fabric may be formed by needlepunching a web at a penetration density of less than or equal to about 150 penetrations per square centimeter and a penetration depth of about 5-20 mm, wherein the needles are spaced apart 5 mm or greater.

  • Publication number: 20070283493
    Abstract: The present invention relates to a flame-retardant removable cover which may be applied to a mattress. The removable cover, when applied to mattress, may reduce the peak heat release rate and/or total energy released in accordance with 16 CFR 1633 testing protocols. The cover may comprise a non-woven material. The removable cover may also comprise a non-woven type construction and an elastomeric material. The removable cover may therefore be designed with respect to the different requirements of those mattresses to which it may be applied to assist in meeting open flame mattress flammability standards.

  • Publication number: 20060228528
    Abstract: The present invention relates to a fire blocking non-woven three-dimensional structure. The structure may include a fabric having a multiplicity of compressible projections wherein the projections return substantially to their original shape after being compressed by 50%. The fabric may include a layer of non-woven and/or metallic film or foil fire blocking material.

  • Patent number: 6281258
    Abstract: A sponge of decrystallized cellulose modified by an acetyl group content, where the average degree of substitution is 0.2 to 1.5. No organic or inorganic sulfur compounds are present in the sponge. The sponge is produced by treating pulp with sodium hydroxide solution, then treating it with acetylating substances, drying and dissolving in an organic solvent with the addition of a pore-forming salt, fibers and optionally pigment dyes, pressing the mixture into a perforated mold whose receiving volume corresponds to the dimensions of the sponge to be produced, then placing the mold with its contents in boiling water, and removing the sponge thus formed in the mold.

  • Patent number: 6281259
    Abstract: A sponge cloth of decrystallized cellulose modified by the acetyl group content, where the average degree of substitution is 0.2 to 1.5. The cloth does not contain any organic or inorganic sulfur compounds. The sponge cloth is produced by treating wood pulp with sodium hydroxide solution, then treating it with acetylating substances, drying and dissolving in an organic solvent with the addition of a pore-forming salt, fibers and optionally pigment dyes and foaming agents, spreading the mixture on a web and boiling in water with subsequent drying to form a finished cloth.
