A WATER-RESISTANT SHEET MATERIAL

摘要

A water-resistant sheet material comprising a fabric base layer (20) which is made of knitted threads of high density polyethylene (HDPE) and which is coated on both sides thereof with a polymer coating compound of low density polyethylene (LDPE) which provides the sheet material with water-resistant properties. The fabric base layer comprises a single series of 400 Denier monofilament threads which are formed into pillar stitches, a second series of 350 Denier monotapes which are knitted in zig-zag fashion to form a Sammt stitch, and a third series of 350 Denier monotapes which are added as a filler. The fabric base layer is coated on one side thereof with the LDPE coating layer, is turned over and the other side is similarly coated with a further LDPE coating layer (26) thereby to coat both sides of the fabric base layer.
