IICRC CCT Carpet Cleaning Technician Exam Questions
and Practice Test | 70 Verified Q&A (2026/2027 Edition)
IICRC Carpet Cleaning Technician (CCT) Certification Examination
==============================
SECTION 1: Carpet Fibers and Construction
==============================
Question 1
Which of the following is a natural fiber commonly used in residential carpet
manufacturing?
A. Nylon
B. Polyester
C. Wool
D. Olefin
Correct Answer: C
Rationale: Wool is a natural fiber derived from sheep and is one of the most common
natural fibers used in carpet manufacturing. Nylon (Option A), Polyester (Option B), and
Olefin (Option C, also known as polypropylene) are all synthetic fibers. Wool carpets are
valued for their durability, resilience, and natural soil resistance but require specialized
cleaning approaches.
Question 2
,What is the primary advantage of solution-dyed nylon fiber in carpet construction?
A. Lower production cost
B. Superior colorfastness and bleach resistance
C. Softer hand feel than staple fiber
D. Easier to recycle
Correct Answer: B
Rationale: Solution-dyed nylon has color added during the extrusion process before the
fiber is formed, resulting in color that extends throughout the entire fiber. This provides
superior colorfastness and makes the fiber resistant to bleaching agents and fading
from UV exposure. While solution-dyed nylon may have a different cost structure, its
primary advantage is color stability and bleach resistance.
Question 3
In carpet construction, what does the term "pile" refer to?
A. The backing material of the carpet
B. The visible surface yarns that stand up from the backing
C. The adhesive used to attach the backing
D. The padding placed beneath the carpet
Correct Answer: B
Rationale: The pile refers to the visible surface yarns that extend upward from the
primary backing of the carpet. These are the fibers that are walked on and that require
cleaning. The backing (Option A) is the foundation material, the adhesive (Option C)
bonds components together, and padding (Option D) is placed beneath the carpet for
cushioning.
,Question 4
Which carpet construction method involves cutting the loops of yarn to create a plush,
velvety surface?
A. Loop pile
B. Cut pile
C. Level loop
D. Berber
Correct Answer: B
Rationale: Cut pile construction involves cutting the loops of yarn, which creates
individual yarn tips that stand upright, producing a plush, velvety surface. Saxony and
plush carpets are examples of cut pile. Loop pile (Option A) leaves loops uncut, level
loop (Option C) is a type of loop pile with uniform height, and Berber (Option D) typically
refers to loop pile construction with larger, often multicolored loops.
Question 5
A technician is inspecting a carpet and observes that individual fibers are shedding and
creating fuzz on the surface. This is most likely characteristic of which fiber type or
condition?
A. Solution-dyed nylon
B. Staple fiber carpet with loose fiber ends
C. Continuous filament polyester
D. Solution-dyed olefin
Correct Answer: B
Rationale: Staple fiber carpets are made from short lengths of fiber (staples) that are
spun into yarn. New staple fiber carpets commonly shed loose fiber ends during the first
, few cleanings, which is normal and not a defect. Continuous filament fibers (Options A,
C, D) do not have this shedding characteristic because they are made from continuous
strands of fiber.
Question 6
What is the primary difference between bulked continuous filament (BCF) nylon and
staple nylon in carpet construction?
A. BCF nylon is always solution-dyed
B. BCF nylon is made from continuous strands and does not shed, while staple nylon is
made from short fibers and may shed
C. BCF nylon is only used in commercial carpets
D. Staple nylon is more resistant to abrasion
Correct Answer: B
Rationale: Bulked Continuous Filament (BCF) nylon is made from continuous strands of
fiber that are texturized (bulked) to create yarn. It does not shed loose fibers. Staple
nylon is made from short fiber lengths (staples) that are spun into yarn and may shed
loose fibers, especially when new. Both can be used in residential and commercial
applications, and abrasion resistance depends on fiber type and construction quality.
Question 7
Which synthetic fiber is known for having excellent stain resistance to acid-based stains
but poor resistance to oil-based soils and is commonly used in loop pile Berber-style
carpets?
A. Nylon
B. Polyester
C. Olefin (Polypropylene)
