PURPOSE: To obtain a sheet having high peeling strength in layer of interlaced material of fibers and excellent creep characteristics, comprising a sheet of interlaced material of fiber consisting essentially of fine fiber having a noncircular section prepared by dividing a layer split type conjugate fiber composed of plural thermoplastic polymers as a ground fabric.
CONSTITUTION: The objective sheet obtained by using a fiber sheet which comprises an interlaced material of fiber consisting essentially of fine fiber having a noncircular section prepared by at least partially dividing a layer split type conjugate fiber composed of plural thermoplastic polymers such as polyethylene terephthalate or nylon as a ground fabric, having ≤1 denier fineness (preferably 0.8-0.001 denier average fineness) and has ≥3kg/25mm ply separation strength, as a ground fabric, providing at least one side of the ground fabric with a tacky agent layer and laminating a release sheet to the tacky agent layer.
