Abstract: Drainage liners and geomembranes including the drainage liners are disclosed herein. The drainage liners have a woven scrim made of warp tapes and weft tapes, and have a plurality of high-denier strands each superimposed upon a warp tape or each superimposed upon a weft tape and each interwoven into the woven scrim by oppositely oriented tapes. The warp tapes or the weft tapes with superimposed high-denier strands thereon are spaced apart within the woven scrim by at least one tape of a same orientation, thereby defining a plurality of parallel channels for fluid flow between nearest neighboring high-denier strands.

Abstract: A crease resistant scrim reinforced coated fabric and associated high density polyethylene (HDPE) tapes that can be used in areas where esthetics are important such as rental tents where the material is constantly folded and installed. The scrim has woven HDPE tapes made from a resin to soften the tape, and a coating comprising a UV masterbatch to resist UV radiation, a Flame resistant (FR) masterbatch to resist fire. The resin with a relatively low flexural modulus and a relatively high Vicat softening point would reduces the scrim's crystallinity and avoids tape shrinkage during coating without overly weakening the tape.
