property, for example, tensile strength and
extension. The course of action of strands in
nonwoven is depicted by the fiber pressing game
plan as well as by fiber directional game plan that
is fiber orientation. The web structure assumes a
noteworthy part in deciding the physical normal
for needle punched fabric. Needle punched fabric
is centered around weight consistency that is MD
and CD [8].
The testing of nonwoven orientation is
carried on lazing instrument NOS 200 machine by
in house strategy. The impact of number of layers
on fiber orientation is appeared if fig. 5.

Figure 5: Nonwoven orientation of fabric
There is a huge impact of number of layers
on fiber orientation. Fiber orientation increments
as number of layers increments. There is 169.60%
expansion in the orientation from number of layer
6 to number of layer 10. There is a huge impact of
number of layers on the nonwoven orientation of
the fabric. As the quantity of layers builds the
randomization of the of the strands increment
which is spoken to by MD/CD ratio. The
randomization is because of more number of
filaments are laid in an alternate bearing for
steady GSM of the fabric.

Number of layers
Mechanical properties of the material are
critical where the material is subjected to stacking
amid its execution. The tensile strength of needlepunched
nonwoven is tried by ISO 9073-3
standard on Instron 5967.
From fig. 6, we can presume that there is no
critical impact of number of layers on the tensile
strength of fabric both in the machine course and
cross bearing. There is no huge impact of number
of layers on breaking heap of the fabric. This is on
the grounds that all the fabric tests were produced
by keeping steady areal density. Due to which the
heap bearing segment per unit zone of fabric stays
same in unit zone. Thus, tensile properties are
unaffected.

Figure 7: Extension of fabric
From fig. 7, it can be watched that there is no
huge impact of number of layers on the extension
of the fabric i.e. drift is vague. This pattern is
because of reality that more randomized
orientation. This randomized orientation prompts
uniform dissemination of the heap toward all
path.

MD/CD ratio is the pointer of an anisotropic
normal for fabric. From MD/CD ratio, we come to
think about directional impacts. Fiber orientation
influences this ratio. Fig. 8 demonstrates the
impact of number of layers on the MD/CD
steadiness ratio of fabric.
