<p><P>PROBLEM TO BE SOLVED: To provide a waterproof fabric that never evolves a gas toxic to human bodies from the plastic used on the fabric when the waterproof fabric is discarded and incinerated, and can resist to high water pressure even when the thickness of the coating layer is thin. <P>SOLUTION: A PEE (polyetherester-based elastomer) to be laminated on the ground fabric, PEEA and PEEB having different melting points from each other are used wherein the PEEA layer is directly arranged on the surface of the ground fabric and the PEEB layer is laminated thereon. Both of the PEEA and PEEB include polyalkylene glycol residues of which≥90 wt.% are polytetramethylene glycol residues, the PEEB melts at≥130°C, the PEEA melts by more than 20°C lower than the PEEB does. In addition, the thickness of the PEEA layer and that of the PEEB layer totals within 5-50μm and the proportion of the PEEA layer is within 5-60 wt.% based on the whole thickness of the coating layers. <P>COPYRIGHT: (C)2003,JPO</p> |
