Claim:
1. A method for making an article for use in lining the interior of a conduit, comprising: using a polyethylene material to form a frameless tube construct; and providing the polyethylene material of the frameless tube construct with a treatment whereupon at least a portion of the polyethylene material is rendered circumferentially distensible, whereupon at least a corresponding portion of the frameless tube construct will experience greater distention in response to an applied distention force as compared to a frameless tube construct formed using an untreated polyethylene material, and whereupon, after distention and removal of the applied distention force, the at least a portion of the frameless tube construct will experience foreshortening of approximately 5 percent or less of a pre-distended length of the portion of the frameless tube construct and recoil of approximately 5 percent or less of a distended diameter of the portion of the frameless tube construct.
