Question

In triaxial weaving three sets of yarns (two warps and one weft) are woven at an angle of ........... degrees.

• A. 0
• B. 45
• C. 60
• D. 90

Hint:

Triaxial weaving always involves yarns intersecting at 60° to create hexagonal patterns, giving higher strength.

Answer 1

The Correct Option is C

Step 1: Understanding triaxial weaving.
Unlike conventional weaving, which uses two sets of yarns (warp and weft), triaxial weaving uses three yarn systems.
These include two sets of warp yarns placed diagonally and one set of weft yarns.
Step 2: Geometry of the weave.
In triaxial weaving, the yarns intersect each other at equal angles to form a stable hexagonal structure.
This requires each set of yarns to be at an angle of 60° with respect to each other.
Step 3: Advantages.
The 60° arrangement improves strength, dimensional stability, and resistance to shear compared to ordinary woven fabrics.
Step 4: Conclusion.
Thus, in triaxial weaving, the three yarns are woven at 60° angles.
