Title:
METHOD FOR PRODUCING SPUN-BONDED NONWOVEN FABRIC
Document Type and Number:
Japanese Patent JP2013129925
Kind Code:
A
Abstract:

To provide a method for producing a spun-bonded nonwoven fabric which can produce a curvature corrected and highly smooth spun-bonded nonwoven fabric by correcting curvature and irregularity on the surface efficiently.

The method for producing a spun-bonded nonwoven fabric, in which the curvature corrected spun-bonded nonwoven fabric is produced from a curved belt-like spun-bonded nonwoven fabric, comprises the steps of: bringing a spun-bonded nonwoven fabric 2 having elasticity in its width direction into contact with a heating roller 3 while conveying the nonwoven fabric 2 in its longitudinal direction to heat the nonwoven fabric 2 to a temperature of a melting point or less and a softening point or more of a constituent fiber thereof; and just thereafter, bringing the nonwoven fabric 2 into contact with a cooling roller 4 having a smooth surface to cool the nonwoven fabric 2 rapidly.
