GARMENT USED FOR PROTECTION FROM ENVIRONMENTAL POLLUTION
Document Type and Number:
Japanese Patent JPH0268075
Kind Code:
A
Abstract:
PURPOSE: To protect a wearer or user from chemical, biological, or nuclear environmental pollution and harmful action of similar environmental pollution by providing a wear with a filter means covering an opening so as to filter drawn-in polluted air, a guide tube to guide exhaled air to atmospheric air, and a valve means communicated with a guide tube so as to inhibit polluted air to intrude into a wear through a guide tube. CONSTITUTION: A filter means or a section between a filter 30 to a filter 32 is similarly fused using ultrasonic around a section from an opening 33 to an opening 35 along a joint line 21. As an wearer wearing this protective wear 10 breathes through a nose, the wear functions so as to pass air through from the filter 30 to the filter 32. Only air exhaled by the wearer flows out from the wear 10 through a guide tube 65 and all sucked air comes into the wear 10 through from the filter 30 to the filter 32. Even when a valve 90 is opened, the wearer dose not inhale pollutant through a filter 95 since there is almost no pollutant with a particle size smaller than 0.3μm.
