PURPOSE:To obtain inexpensive WARIFU (agricultural nonwoven fabric) having excellent moisture retention, dehumidifying properties and drop-free properties, by laminating a water absorbing film to a netlike material and integrating. CONSTITUTION:High-density polyethylene is fused to an ethylene-vinyl acetate copolymer containing about 5% saponified vinyl acetate-methyl acrylate copolymer and blow molded to give a composite film. The high-density polyethylene thus obtained is split, lengthwise and breadthwise laminated and bonded by heating under pressure to give WARIFU made of split fiber. |
