Abstract
The laminated sheet of the present invention comprises (A) a nonwoven fabric having a basis weight of 30 g/m.sup.2 or less made of polyolefin-based ultra-fine fibers of 5 .mu.m or less in average fiber diameter; (B) a heat-bonding nonwoven fabric having a basis weight of 15 g/m.sup.2 or less made of thermoplastic elastomer ultra-fine fibers of 15 .mu.m or less in average fiber diameter; and (C) a spun-bonded nonwoven fabric having a basis weight of 30 g/m.sup.2 or more made of thermoplastic polymer fibers. The nonwoven fabric A and the spun-bonded nonwoven fabric C are face-bonded via the heat-bonding nonwoven fabric B. The laminated sheet is excellent and well-balanced in a wind breaking performance, a water vapor permeability and a waterproof performance. The laminated sheet is also excellent mechanical properties and durability. With these excellent properties, the laminated sheet is suitably used as house wrap materials and roof underlay sheets.
