A method for producing a novel silicone foam by reaction of a polyisocyanate with a silicone oligomer having a plurality of functional end groups with active hydrogens, optionally in the presence of fire-retardants, under foam forming conditions which creates a new silicone foam for use in items such as residential upholstered furniture industry, seat cushions and bedding etc., and specifically for use in applications that require, high resilience and fire-retardant properties such as aircraft and surface transportation seat cushioning, military and shipboard mattresses etc.

The invention relates to slickened or siliconized flame resistant fiber blends that are well suited for use in mattresses, boxsprings, upholstered furniture, fiber-filled bed clothing, transportation seating or any end use application where a soft materials are desired for flame resistant (FR) purposes. Some of the fibers in the blend are slickened. The FR fibers incorporated into these blends include both char forming FR fibers and oxygen depleting FR fibers. FR char-forming fibers are those which exhibit little shrinkage when exposed to direct flame and are not spun from polymers manufactured with halogenated monomers. Oxygen depleting FR fibers are spun from polymers manufactured with halogenated monomers.

A retrofit cover for fully or partially enclosing a mattress, wherein the cover is formed of a unitary, integrally formed fabric having a fire barrier element. The cover is capable of rendering mattresses, mattress foundations, upholstered furniture article and other articles filled with resilient cushioning materials that were not originally manufactured to meet a full-scale open flame standard capable of passing such newly mandated standard for performance in newly manufactured items. When tested in accordance with the flame resistance test protocols of 16 CFR 1633 or TB 603, the item encased in the retrofit cover has a maximum heat release rate of less than 200 kW and a total energy release of less than 25 MJ in the first five minutes of the test.

A method is provided for after-treating fabric with a fluoroacrylate emulsion by spraying or immersion. The immersion can be carried out in a laundering process (preferably in a late cycle of the process) or even under poorly-controlled conditions (e.g. field conditions). The spraying embodiment of this method is useful for treating large, previously manufactured items comprising fabric (e.g. upholstered furniture, tents, awnings, and the like) with an aerosol spray containing micrometer or submicrometer-sized droplets of a diluted version of the fluoroacrylate emulsion. In all embodiments, the fluoroacrylate emulsion contains, dispersed therein with the aid of a surfactant system, essentially a single hydrophobic component comprising a particulate fluoroacrylate copolymer having repeating units of the formulas I and II wherein Rf is a C8-rich fluorinated alkyl radical; R and R1 are hydrogen or alkyl; and R2 is hydrogen or substituted or unsubstituted alkyl. The aqueous dispersion further contains, in addition to the surfactant system, a minor amount of polar organic liquid. Depending upon the melting or softening point of the fluoroacrylate copolymer, drying under heat can be optional and in any event can be carried out at temperatures below 100 DEG C.

A convertible piece of upholstered furniture can be converted via motorized conversion aids from a seat function into a bed, by way of any desired number of intermediate stages, and vice versa. All movable parts can be fully stressed by a person during conversion, even when a person is sitting or lying on the piece of furniture. These changes can take place even when the piece is being used by a person, whereby each movable part of the piece of upholstered furniture can be changed by means of a motor drive having a control. The footrest and the seat part are configured so that they can move out of a base frame with their metal fittings. A lever construction arranged on the metal fitting of the footrest and a motor drive adjusts the height and angle of the footrest and moves the piece of furniture to the various positions.

The invention relates to the use of a flame resistant (FR) three-layer double-knit fabric, also know as a matelasse fabric. The top layer is of standard non-FR face yarn, the middle layer is of a FR filler spun yarn and the bottom layer is of a FR spun yarn or FR filament yarn. This FR matelasse fabric can be used to protect a mattress, foundation, upholstery cushion, pillow, office panel, transportation seat or any other article requiring FR protection. In this invention, a matelasse fabric is formed by circular double knitting a FR spun or FR filament yarn into the bottom portion of the fabric, utilizing a heavy cotton count FR filler spun yarn for the middle layer and using conventional non-FR yarns for the top layer. The invention has particular applicability in the formation of FR mattresses and foundations that require passage of large open flame tests such as CPSC's 16 CFR Part 1633, California's Test Bulletin 603 and Test Bulletin 129 and in the formation of FR upholstered furniture that requires passage of California's Test Bulletin 133 or British Standard 5852 using the crib 5 ignition source or higher.

A method is provided for after-treating fabric with a fluoroacrylate emulsion by immersion, typically under poorly-controlled conditions (e.g. field conditions), and a second embodiment of this method is provided for treating large, previously manufactured items comprising fabric (e.g. upholstered furniture, tents, awnings, and the like) with an aerosol spray containing micrometer or submicrometer-sized droplets of a diluted version of the fluoroacrylate emulsion. In both embodiments, the fluoroacrylate emulsion contains, dispersed therein with the aid of a surfactant system containing an amphoteric surfactant, essentially a single particulate fluoroacrylate copolymer having repeating units of the formulas I and II wherein Rf is a fluorinated alkyl radical; R and R1 are hydrogen or alkyl; and R2 is hydrogen or substituted or unsubstituted alkyl. The aqueous dispersion further contains, in addition to the surfactant system, a minor amount of polar organic liquid. In the first embodiment, drying under heat is optional and in any event can be carried out at temperatures below 55 DEG C. In the second embodiment, drying under heat is highly impractical but is also unnecessary.
