Question

The KES-FB module of Kawabata hand evaluation instruments gives \underline{\hspace{2cm}.
A. Linearity of the load elongation curve.
B. Compression resilience.
C. Tensile energy.
D. Bending rigidity.}

• A. A, C and D only
• B. A, B and C only
• C. A, B, C and D
• D. A, B and D only"

Hint:

The Kawabata Evaluation System (KES) is a comprehensive suite of tools to measure "fabric hand." It covers all the basic ways you can deform a fabric with your hands: - Stretching (Tensile) - KES-FB1 - Bending - KES-FB2 - Squeezing (Compression) - KES-FB3 - Rubbing (Surface) - KES-FB4 All the properties listed fall under these categories.

Answer 1

The Correct Option is C

Step 1: Understand the Kawabata Evaluation System (KES-FB). This is a set of standardized instruments designed to objectively measure the low-stress mechanical properties of fabrics that relate to the subjective feeling of "hand" (e.g., softness, stiffness, smoothness). The system consists of four main instruments.

Step 2: Identify the properties measured by each instrument.
- KES-FB1 (Tensile and Shear Tester): Measures properties related to stretching and shearing the fabric. This includes tensile strain, linearity of the load-elongation curve (A), and tensile energy (C). - KES-FB2 (Pure Bending Tester): Measures how a fabric resists bending. This gives bending rigidity or stiffness (D). - KES-FB3 (Compression Tester): Measures the properties of the fabric when it is compressed. This includes thickness, compressibility, and compression resilience (B). - KES-FB4 (Surface Tester): Measures surface friction and roughness.

Step 3: Evaluate the listed properties. All four properties listed (A, B, C, and D) are standard parameters measured by the different modules of the KES-FB system. Therefore, all are correct.
