Title:
STRETCH NONWOVEN FABRIC, STRETCH LAMINATE AND PROCESSES FOR PRODUCTION OF BOTH
Document Type and Number:
WIPO Patent Application WO/2005/007961
Kind Code:
A1
Abstract:
The invention provides a stretch nonwoven fabric which is soft and excellent in the contour-following properties and exhibits little tenseness; and a process for the production of a stretch laminate composed of the fabric and an extremely thin stretch film, that is, a stretch nonwoven fabric made of a continuous block copolyester filament fiber which fabric has a fiber diameter of 3 to 30μm and a basis weight of 20 to 200g/m2 and exhibits an elongation at break of 100 % or above, a recovery from 20% elongation of 95% or above, and a stress at 100% elongation at least 1.4 times that at 50% elongation; and a process for the production of a stretch laminate which comprises shrinking a nonwoven fabric made of a block copolyester and having a fiber diameter of 3 to 25μm at 70 to 200°C in at least one direction by 5 to 80% and extrusion-laminating the resulting fabric with a film made of a block copolyester having a melting point of 150 to 230 °C and having a thickness of 5 to 50μm.
