Question

Abrasion refers to wearing away of fabric when it rubs against another surface. The types of abrasion are:
A. Straight abrasion
B. Edge abrasion
C. Curved abrasion
D. Flex abrasion
E. Flat abrasion
Choose the correct answer from the options given below :

• A. \( \text{A, C and D Only} \)
• B. \( \text{A and C Only} \)
• C. \( \text{B, D and E Only} \)
• D. \( \text{B and D Only} \)

Hint:

The Martindale test is the most common method used to measure "Flat Abrasion," where a sample is rubbed in a "Lissajous" (figure-8) pattern against a standard wool abrasive.

Answer 1

The Correct Option is C

Concept: Abrasion resistance is a critical durability property of textiles. It describes how well a fabric can withstand surface wear caused by friction.

Step 1: Define the standard types of textile abrasion.

• Flat (Plane) Abrasion (E): Wear that occurs when a flat area of the fabric is rubbed against a flat surface (e.g., a chair seat).
• Edge Abrasion (B): Wear that occurs on the edges or folds of a garment, such as cuffs, collars, or hems.
• Flex Abrasion (D): Wear that occurs when the fabric is repeatedly bent and rubbed, which involves both tension and compression (e.g., the knee or elbow areas).

Step 2: Identify the distractors.
Terms like "Straight" or "Curved" abrasion are not standard classifications in textile testing (like the Martindale or Wyzenbeek tests).
