Abstract
An adhesive tape for preventing implosion of a CRT is provided. The tape includes a backing, a pressure sensitive adhesive layer on one side of the backing and a hot melt adhesive layer on the opposite side of the backing. The backing is a union cloth of natural or synthetic fiber yarns as the warps and glass filament yarns as at least part of the wefts.
Claims9
An adhesive tape for preventing implosion of a cathode ray tube, comprising:
- a backing having first and second main surfaces,
- a pressure sensitive adhesive layer disposed on said first main surface of the backing, and
- a hot melt adhesive layer disposed on said second main surface of the backing,
- said backing being a union cloth including natural or synthetic organic fiber yarns as the warps and, as the wefts, a combination of glass filament yarns and natural or synthetic organic fiber yarns,
- wherein in the wefts there are one to thirty yarns of said natural or synthetic organic fiber yarns arranged between each of the glass filament yarns and the glass filament yarn on each side of said each glass filament yarn,
- said adhesive tape having a transverse compression rupture strength of at least 5 kgf/cm,
- all of said natural or synthetic organic fiber yarns have a yarn counting of 10 S to 40 S, wherein S represents gram weight per one hundred meter length,
- a density of said warp yarns is 10 to 30 per 25 mm and a density of said weft yarns is 10 to 25 per 25 mm, and
- all of said natural or synthetic organic fiber yarns are black.
