Question

Which of the colour problems create horizontal off shade band across fabric?

• A. Tendering
• B. Metamerism
• C. Frosting
• D. Barre'

Hint:

Think of "Barre" like the "bars" of a cage—horizontal lines across the fabric. It's almost always a yarn-related problem.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question asks for the specific term for a common defect in dyed knitted or woven fabrics where horizontal lines or bands appear.

Step 2: Detailed Explanation:

• Barre' (D) is a textile defect characterized by repetitive, horizontal stripes or bands of a different shade. It is usually caused by physical or chemical variations in the yarns (e.g., tension differences during knitting or weaving).

• Tendering (A) is the weakening of fabric, often due to chemical over-exposure or sunlight.

• Metamerism (B) is when two colors match under one light source but look different under another.

• Frosting (C) is a localized color change caused by abrasion (common in blends like polyester/cotton) where the surface fibers are worn away, revealing the white core.

• Since the problem mentions "horizontal off-shade bands," Barre' is the only appropriate term.

Step 3: Final Answer: The defect is called Barre'.
