A student records the loss of 50% in the following type of strength usage of Amylases in desizing
Show Hint
Desizing mainly reduces tensile strength due to removal of size coating.

- Tensile
- Ballistic
- Bursting

The Correct Option is B
Solution and Explanation
Concept:
Amylase enzymes are used in desizing to remove starch from woven fabrics. During desizing, fabric strength is affected due to removal of size material and partial weakening of yarn interlacements. The most affected property is tensile strength, which directly depends on yarn integrity.
Step 1: Understand desizing effect.
Desizing removes starch-based size coating, which:
• Holds yarns together temporarily
• Improves weaving strength
Step 2: Analyze strength types.
• Tensile strength → yarn breaking under longitudinal load
• Tear strength → propagation of a cut
• Burst strength → multi-directional stress
• Ballistic strength → impact resistance
Step 3: Identify maximum affected property.
Since desizing directly weakens yarn binding, tensile strength shows maximum reduction. \[ \boxed{\text{Tensile Strength}} \] Thus, \[ \boxed{\text{Option (B) is correct.}} \]
