3. INTRODUCTION
• The 3D weaving technology is used for the
production of only specially industrial fabrics.
Keeping high level of security in mind for
protective clothing, 3D fabric play important
role.
4. A single-fabric system, the constituent yarns of
which are supposedly disposed in a three mutually
perpendicular plane relationship

5. DRAWBACKS OF 2D CONSTRUCTION
• Anisotropic
• Poor in-plane shear resistance
• Less modulus than the fiber material due
to presence of crimp
6. 3D STRUCTURE
3:48 PM
Yarns are arranged
perpendicular to each
other in X, Y and Z
directions
No interlacing or crimp
exists between yarn
Thickness can be increased
High Fibre Volume Fraction
7. CLASSIFICATION OF 3D STRUCTURES
I) Based on type of 3D Structures
3D Solid:
3D Hollow:
Flat surface
Uneven surface
3D Shell:
By weave combination
By differential take-up
By moulding
3D Nodal
II) Based on type of
mechanism
3D Woven
3D Knitted
3D Nonwoven
3D Jacquard design
Braided structure
III) Based on type of
weaving process
2D weaving – 3D
fabrics
3D weaving – 3D
fabrics
NOOBING
Orthogonal
Warp Interlock
Angle Interlock
8. 3D Solid structure
Orthogonal
It is characterized by straight yarns in warp, weft
and thickness directions
This structure can provide a greater volume
fraction than Warp interlock structures
3:48 PM
9. 3D SOLID STRUCTURE
It is a multilayer fabric
Used for flat panel reinforcement
Normally woven on a shuttle loom
Warp Interlock
10. 3D SOLID STRUCTURE
Structures are distinguished by the
individual layers
Each layer may be of different weave
Stitching of layers
Structure ranges from 2 to 4 layers
Angle Interlock
11. 3D HOLLOW STRUCTURE
a) Flat surface-where three or more layers of fabric are
used, the layer of fabric connecting the top and
bottom layers will be woven with longer length than
the top and bottom layers.
b) Uneven surface-adjacent layers of fabrics are
combined and separated at arranged intervals.
12. 3D SHELL STRUCTURE
a) By weave combination
b) By differential take-up
c) By moulding
13. BY WEAVE COMBINATION
Concentric rings were planned and gradient change of
weaves was employed in the areas between two
adjacent rings
14. BY DIFFERENTIAL TAKE-UP
The conventional one-piece take-
up roller was replaced by one
made up by many discs that are
electronically controlled to
perform individual take-up
movement
15. BY MOULDING
Due to the extensibility of yarns
and fabrics and the allowance of
shear, most flat woven fabrics
can be molded into doubly
curved surfaces to some extent.
16. 3D NODAL STRUCTURE
A 3D nodal fabric refers to a fabric that facilitates a
network formed by different tubular or solid members
joining together
18. APPLICATIONS OF 3D FABRICS
• Automotive engineering
• Aeronautics
• Construction
• Medical material
• Transport applications
• Protective clothing
• Ballistic and various industrial uses
19. APPLICATIONS OF 3D FABRICS IN PROTECTIVE CLOTHING
Protective clothing is the applications, where a high level of
protection is expected from the lightest possible components and
3D fabric is one of the best option for this because it have some
characteristic like-
• Thick in dimensions
• Damage tolerance and impact resistance
• Flexural
• Tensile and compressive stiffness
• strength
23. VELVET FABRICS FOR UPHOLSTERY
• Velvet fabrics are a class of pile fabrics which are divided into two as warp pile fabrics
and weft pile fabrics known as velveteen according to the pile direction
