  • Patent number: 10966639
    Abstract: A respiratory effort belt to be worn by a person undergoing a sleep study comprises a PVDF piezo film transducer having opposite major surfaces metalized and electrical leads electronically connected to the metalized surfaces adhesively bonded to an inelastic cover layer that is, in turn, adhesively joined to an stretchable elastic band that functions as a belt to be secured to the person's chest or abdomen. The transducer produces a time-varying output voltage waveform due to rubbing contact between the elastic band and the PVDF film and not due to tensile forces acting on the film as the person's chest or abdomen rises and falls with inspiration and expiration.

  • Publication number: 20120077399
    Abstract: The present invention provides a high-performance, low toluene emission abnormal noise preventing sheet that is fabricated using an acrylic-based pressure-sensitive adhesive (PSA). The abnormal noise preventing sheet 10 of this invention has a substrate 12 comprising a nonwoven fabric 122 and a PSA adhesive layer 14 provided on a first side 12A of the substrate. The PSA constituting the PSA layer 14 contains an acrylic polymer and a tackifier. This sheet 10 has a toluene emission level of 20 ?g or less per gram of PSA layer when the PSA layer 14 is heated at 80° C. for 30 min.

  • Patent number: 8143524
    Abstract: The invention relates to an industrial adhesive tape. The tape includes a tape-shaped textile dyed backing and an adhesive coating, in particular a pressure sensitive adhesive coating applied to at least one side of the textile dyed backing. To achieve significantly reduced inherent discoloration or decolorization and also reduced discoloration of the wrapped materials, and hence improved compatibility of the adhesive tape with the materials to be adhered together, such as cablesets, the textile backing is fabricated from spun-dyed threads or fibers.

  • Patent number: 8105450
    Abstract: A protection sheet and method of protecting a substrate is disclosed. In an embodiment, the protection sheet comprises an adhesive coated nonwoven material. In an embodiment a surface of the protection sheet captures and retains paint overspray, dust, dirt and other contaminants so as to provide a cleaner paint job. In an embodiment the protection sheet may be laminated to a second nonwoven or woven material to allow clean removal after extended use. The protection sheet may be used to protect horizontal or vertical substrates, and is particularly suited to protect the surfaces of a paint booth used in automotive spray-painting operations.

  • Patent number: 8071490
    Abstract: An acrylic pressure-sensitive adhesive composition according to the present invention comprises: acrylic copolymer (A) formed by copolymerizing i) alkyl(meth)acrylic acid ester monomer wherein the carbon atom of alkyl group is 2 to 14, ii) monomer having a functional group capable of crosslinking, iii) methyl(meth)acrylate monomer, iv) vinyl acetate monomer, v) glycidyl(meth)acrylate, and vi) crosslinking agent having 5 to 15 of alkyleneoxide groups and at least two acrylate group or vinyl group; and flame retardant (B). The acrylic pressure-sensitive adhesive composition improves the adhesive property and the dispersion of the flame retardant by controlling the crosslinking structure of the acrylic copolymer, such that a surface finishing material comprising the same can have the excellent adhesion and fireproof.

    Abstract: A flame retardant patch for repairing a tear or hole in clothing or gear includes a flame resistant fabric and a pressure sensitive adhesive bonded to the fabric by hot melt lamination. The pressure sensitive adhesive contains halogenated flame retardant compounds. A release paper covers the pressure sensitive adhesive and is removed to allow application of the flame retardant patch to the clothing or other item being repaired. The patch is attached by applying pressure to the top fabric surface of the patch for approximately 45 seconds using the convex surface of a spoon-like object.

  • Publication number: 20110097958
    Abstract: Provided herein is a method for producing a double-sided adhesive tape, which causes neither generation of wrinkles nor cutting of a nonwoven fabric base material even when a pressure-sensitive adhesive is applied to the nonwoven fabric base material at a higher speed than in the case of the prior art, and also has improved productivity. Disclosed is a double-sided adhesive tape including a nonwoven fabric base material containing substantially no binder component and having a tensile strength in a longitudinal direction of from 4.1 to 10.0 N/10 mm; and a pressure-sensitive adhesive layer provided on both surfaces of the nonwoven fabric base material; wherein the double-sided adhesive tape has an initial tensile strength in the longitudinal direction of 17.0 N/10 mm or more.
