DUST SHEET FOR REDUCING BRAKE NOISE AND BRAKE SYSTEM COMPRISING A DUST SHEET
The invention relates to a dust sheet for a vehicle brake configured for reducing brake noise, to a disk brake system comprising a dust sheet and to a method for making a dust sheet, wherein the dust sheet comprises, at least in a section, two or more layers.
LAMINATE SHEET, SANITARY MATERIAL, MEDICAL MATERIAL, AND METHOD FOR MANUFACTURING LAMINATE SHEET
A laminate sheet includes a water-vapor permeable polyurethane film having a hard segment phase and a first spunbond nonwoven fabric disposed at one side in a thickness direction of the water-vapor permeable polyurethane film. The first spunbond nonwoven fabric contains stretchable fibers containing a thermoplastic polyurethane and non-stretchable fibers containing a polyolefin. The melting point of the hard segment phase is 65□ or more and 140□ or less.
PLEATABLE NONWOVEN
The disclosure relates to a pleatable nonwoven fabric including greater than 50% by weight of a majority polymer component, based on total weight of the fabric, and a minority polymer component, wherein there is a difference of at least 10° C. in melting point between the majority polymer component and the minority polymer component, and wherein the fabric is arranged in layers with a first layer, a second layer, and a mid-layer positioned between the first layer and the second layer, and wherein the top layer and the bottom layer comprise a plurality of bicomponent fibers comprising both the majority polymer component and the minority polymer component; and wherein the mid-layer comprises monocomponent fibers constructed from either the majority polymer component or the minority polymer component. A method of making the pleatable nonwoven fabric is also provided.
POLYTETRAFLUOROETHYLENE COMPOSITE FILTER MATERIAL AND PREPARATION METHOD AND USES THEREOF
The present invention relates to the field of air filtration, in particular to a polytetrafluoroethylene composite filter material and a preparation method and uses thereof. The polytetrafluoroethylene composite filter material comprises a support layer and a polytetrafluoroethylene microporous membrane layer, and the support layer and the polytetrafluoroethylene microporous membrane layer are compounded by an adhesive, wherein the adhesive comprises a two-component polyurethane adhesive, a pore forming agent and an inorganic filler. The present invention adopts a two-component solvent-free polyurethane adhesive, and by adding a low-temperature pore forming agent and an inorganic filler, the pore forming agent forms an irregular pore channel structure at the bonding interface during curing, and the inorganic filler prevents the adhesive from entering the micropores of the polytetrafluoroethylene membrane, so that the air permeability and filtration efficiency of the polytetrafluoroethylene microporous membrane are not affected after compounding; and the prepared polytetrafluoroethylene composite filter material has good air permeability, high peel strength, good filtration efficiency and good barrier effect.
SOUND ABSORBING STRUCTURES
An acoustic structure presenting a front surface and a back surface is provided. The acoustic structure includes a support layer comprising the back surface, a honeycomb core comprising a thickness defined between a back and a front, and a plurality of walls that define a plurality of honeycomb cells, wherein the plurality of honeycomb cells extend through the thickness of the honeycomb core opening out toward at least the front, and wherein the back of the honeycomb core is affixed to the support layer, a mesh layer affixed to the front of the honeycomb core, and a knit fabric layer affixed to the mesh layer and conforming to the front surface of the acoustic structure.
Disposable surgical gown
A disposable surgical gown is provided. The gown includes a front panel and sleeves formed from a first spunbond layer, a nonwoven (e.g., SMS) laminate, and a liquid impervious, moisture vapor breathable elastic film disposed therebetween. The gown also includes a first and second rear panels formed from a nonwoven laminate that is air breathable and allows for an air volumetric flow rate ranging from about 20 standard cubic feet per minute (scfm) to about 80 scfm. The gown further includes a collar formed from an air breathable knit material positioned adjacent a proximal end of the gown. The collar defines a neck opening having a v-neck shape adjacent the front panel. The v-neck shape forms an angle of greater than 90° at the neck opening. The combination of features results in a reduced-glare gown that is stretchable and impervious to liquids, yet can still dissipate heat and humidity.
Ballistic protection material and use thereof
The present invention relates to a protective material, preferably a ballistic protection material, having a protective function against ballistic active bodies (launch bodies), in particular against reinforcement-penetrating and/or armor-piercing projectiles, thrust bodies or penetrating bodies, and to the use thereof.
Patient securement system for the surgical Trendelenburg position
A patient securing overlay is provided that includes a sheet of fabric for supporting a patient's torso on a surgical table. The sheet of fabric has an upper surface configured to face the patient and a lower surface configured to face a surgical table mattress or underbody support. The sheet of fabric includes friction enhancing elements applied to at least a portion of the upper surface thereof. The sheet of fabric can include an extension at a foot end of the sheet of fabric that provides material to be tucked under a foot end of the surgical table mattress or underbody support for securing the foot end of the sheet of fabric to the surgical table mattress or underbody support. The extension can include one or more friction enhancing elements.
Sorting method
A resin granule mass including a plurality of resin granules, and a proportion of resin granules to which a magnetic foreign matter of 50 μm or greater is adhered in the plurality of resin granules is 30% or less.
Papermaking belts having offset openings, papermaking processes using belts having offset openings, and paper products made therefrom
A belt for creping a web in a papermaking process. The belt includes a surface onto which the web is transferred during the papermaking process. A plurality of openings extend through the surface, with the openings being arranged in lines that are offset from lines in the machine direction (MD) and cross-machine direction (CD) of the belt. Paper products, such as absorbent sheets, made from the belt have hollow dome regions and connecting regions between the domes, with the domes being arranged in lines that are offset from lines in the MD and CD of the paper products.
