摘要： This invention relates to a laminate electrical insulation part for an electrical device comprising a thermoplastic film positioned between, adjacent to, and attached to two nonwoven sheets. Each of the nonwoven sheets consists of multicomponent polymeric fibers comprising at least a first polymer and a second polymer, the first polymer having a melting point that is at least 15 degrees Celsius lower than both the melting point of the second polymer and the melting point of the thermoplastic film, and the film is attached to the nonwoven sheets by the first polymer in the nonwoven sheets. The electrical insulation part has a breakdown voltage of at least 3 kilovolts, and a surface having a dynamic frictional coefficient of 0.25 or less. This invention also relates to an electrical device component comprising the laminate electrical insulation part.

摘要： A nonwoven printing medium is provided which is formed from a spunbond nonwoven web of continuous multiple component filaments and optionally a coating on at least one surface of the spunbond nonwoven layer. The spunbond filaments are preferably formed in a sheath-core configuration with a high strength component in the core and a sheath component resulting in an abrasion resistant surface. The printing medium has an improved combination of tensile properties, outdoor durability, and high temperature stability for printing in high temperature printers.
