MANUFACTURE OF NETLIKE RESIN PIPE

摘要

PROBLEM TO BE SOLVED: To provide a netlike resin pipe providing satisfactory installation property and construction property on recessed and projecting faces, preventing its thermal-deformation at the time of pavement, and having excellent water drain performance. SOLUTION: Resin monofilaments are knitted on a flexible mandrel without using a warp and are heat-treated when they are knitted or after they are knitted, and then the flexible mandrel is pulled out to manufacture the netlike resin pipe.
