ABSTRACT:
A water impervious laminated material is described. A preferred embodiment comprises a three-ply hydrophobic microfine fiber structure sandwiched between and fuse bonded to two layers of conjugate fibers having a low melting sheath and a high melting core. The inner ply of the hydrophobic microfine fiber structure is relatively high melting while the two outer plies of the hydrophobic micofine fiber structure film are low melting. The sheaths of the conjugate fibers have been fuse bonded to the hydrophobic microfine fiber structure at a temperature below the melt temperature of the cores of the conjugate fibers so that the cores retain their initial fiber-like integrity.
