, 1. Natural Fiber Identification
Question:
Which fiber is a natural protein fiber commonly used in high‑end
carpet installations?
- (a) Nylon
- (b) Wool
- (c) Olefin
- (d) Acrylic
Correct ANS: (b) Wool
Rationale:
Wool is a natural protein fiber known for its durability, resilience,
natural flame resistance, and inherent soil‑hiding properties. Its
cleaning requirements differ from synthetic fibers and must be
handled at controlled pH and temperature levels.

2. Synthetic Fiber Resilience
Question:
Which synthetic fiber is most popular for installed broadloom carpet
because of its resiliency and soil‑resistance characteristics?
- (a) Polyester
- (b) Nylon
- (c) Acrylic
- (d) Olefin
Correct ANS: (b) Nylon
Rationale:
Nylon is the most widely used synthetic carpet fiber due to its
excellent resilience, high abrasion resistance, and ability to recover
from compression. These qualities make it ideal for high‑traffic
2
,commercial and residential spaces.

3. Moisture and Chemical Resistance
Question:
Which synthetic fiber is known for its excellent resistance to
moisture, staining, and chemical attack, making it a frequent choice
for areas subject to spills?
- (a) Nylon
- (b) Olefin
- (c) Acrylic
- (d) Polyester
Correct ANS: (b) Olefin
Rationale:
Olefin (polypropylene) is hydrophobic and resistant to most
chemicals as well as moisture. Its low affinity for water makes it
particularly suitable for high‑soil and wet environments.

4. Wool Lookalike Fiber
Question:
Which fiber is often chosen as a synthetic substitute for wool due to
its soft appearance and similar texture?
- (a) Acrylic
- (b) Polyester
- (c) Olefin
- (d) Nylon
Correct ANS: (a) Acrylic
Rationale:
Acrylic fibers are designed to mimic the appearance and feel of wool
while offering the benefits of synthetic processing, though they may
3
, have different responses to cleaning chemicals and abrasion.

5. Yarn Crimp Characteristics
Question:
What term describes the natural waviness imparted to yarns during
manufacturing that contributes to carpet resiliency and fiber
recovery?
- (a) Twist
- (b) Crimp
- (c) Ply
- (d) Bouclé
Correct ANS: (b) Crimp
Rationale:
Crimp is the natural wave or bend in a yarn that gives carpet its spring
and resilience. It plays an essential role in recovering after
compression and affects how soils penetrate the carpet fibers.
---
6. Plied Yarn Definition
Question:
In carpet manufacturing, what is the primary purpose of producing a
plied yarn?
- (a) To add color variation
- (b) To combine multiple strands for improved strength and durability
- (c) To increase softness by reducing twist
- (d) To simplify the tufting process
Correct ANS: (b) To combine multiple strands for improved strength
and durability
Rationale:
Plied yarns are created by twisting two or more single yarns together.
