Title:
FIBERS WITH THERMAL ELONGATION PROPERTIES AND NON-WOVEN FABRIC USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/069475
Kind Code:
A1
Abstract:
These fibers with thermal elongation properties comprise a first resin component, and a second resin component having a melting point or a softening point that is lower than the melting point of the first resin component, and at least part of the fiber surface of the second resin component is continuously present in the length direction, and the length extends as a result of applying heat. The rate of change ({(B - A)/A} × 100) of the thermal elongation B at the melting point of the second resin component plus 10°C with respect to the thermal elongation A at the melting point of the second resin component minus 6°C is at least 130%. The first resin component preferably comprises polylactic acid, while the second resin component preferably comprises a polyolefin. The ratio (crimp rate (%)/number of crimps (count)) between the crimp rate (%) measured in accordance with JIS L1015 and the number of crimps (count) measured in accordance with JIS L1015 is preferably between 0.45 and 0.75.
