Title:
STRETCH NONWOVEN FABRIC AND TAPES
Document Type and Number:
WIPO Patent Application WO/2008/015972
Kind Code:
A1
Abstract:
A nonwoven fabric comprising bicomponent fibers having a phase structure made of
plural resins different in heat shrinkage factor, wherein the bicomponent fibers
are orientated nearly parallel to the plane direction and crimped to an average
curvature radius of 20 to 200μm nearly uniformly in the thickness direction.
This nonwoven fabric is substantially free from pressure-sensitive adhesives
and the bicomponent fibers of the fabric are present in a substantially non-fused
state. The bicomponent fibers are each constituted of both a polyalkylene terephthalate
resin and a modified polyalkylene terephthalate resin and may have any of side-by-side
type structure and core-sheath type structure. Since such bimetal-type bicomponent
fibers having specific crimps are contained in the fabric in a properly entangled
state, the fabric has high stretchability and can be easily cut by hand without
scissors, thus being suitable for tapes such as bandages and supporters.
