Title:
TUBULAR BODY
Document Type and Number:
Japanese Patent JP3163430
Kind Code:
B2
Abstract:
PURPOSE: To eliminate dropping of droplets during using with sufficient water absorption and to obviate rising of a temperature of cold air or refrigerant of an air conditioner, etc., to flow therein by forming a water absorption layer of fiber having high water absorption or fabric containing particular polymer having high water absorption.
CONSTITUTION: A tubular member 1 is formed of a tube 2 and a water absorption layer 3 formed on the surface of the tube 2. The tube 2 is formed of polypropylene. The surface of the tube 2 is provided integrally with fabric of nonwoven fabric containing particular polymer having high water absorption as the surface layer 3. Thus, when moisture is adhered to the water absorption layer, the fiber or the polymer having high water absorption can be sufficiently swelled to easily saturate during using to eliminate dropping of the moisture from the surface of the member, to provide high heat resistance and to suppress an external flow of a temperature of fluid in the member.
