Impact of Fiber Cross-Section shapes on the
Properties of Nonwoven Fabric
This article highlights the effects of fiber cross-sectional shapes (round, trilobal) on the compression properties (initial thickness, percentage compression, percentage thickness loss); air permeability and breaking strength of needle punched nonwoven fabric.
Polyester has various industrial and textile applications
due to its easy availability at comparatively lower cost. With the advancement
of fiber technology, polyester fiber has various cross-sectional shapes. The
different structures of the fibers result in different total surface areas of
nonwoven fabrics and different surface characteristics of fiber. This article
highlights the effects of fiber cross-sectional shapes (round, trilobal) on the
compression properties (initial thickness, percentage compression, percentage
thickness loss); air permeability and breaking strength of needle punched
nonwoven fabric.
Air permeability is very important parameter for sound insulation and thermal insulation of nonwoven fabrics. The compression property, air permeability and strength of nonwoven fabric depend on the fiber geometry & arrangement of fiber within the structure. Trilobal cross-sectional fiber has more surface area than the round cross-sectional fiber and trilobal fiber have lobes over the surface, cause problem in the recovery when compression load get removed from nonwoven fabric material. Article paper gives a brief description of the characteristics of nonwoven fabric and its end applications for different cross-sections shapes.
