EXAM QUESTIONS AND CORRECT VERIFIED ANSWERS/

1. You are performing a burn test on an unidentified fabric. The
flame is orange, it smells like burning hair, and the ash is
crushable and powdery. What is the most likely fiber content?
A) Cotton
B) Polyester
C) Wool
D) Rayon
Answer: C) Wool
Rationale: The smell of burning hair and a crushable, powdery
ash are characteristic of protein-based fibers like wool and silk.
Cotton and rayon (cellulosic) smell like burning paper, while
polyester (thermoplastic) melts and forms a hard bead.
2. A fabric is labeled as 100% Rayon. What is the primary risk
when cleaning this fabric with water?
A) Color loss
B) Shrinkage and loss of strength
1
,C) Melting of the fibers
D) Rapid drying leading to wrinkling
Answer: B) Shrinkage and loss of strength
Rationale: Rayon is a regenerated cellulosic fiber. When wet, it
can lose a significant amount of its tensile strength (up to 50%),
which often leads to shrinkage and distortion if not handled
carefully.
3. Lignin, a binder found in cellulosic fibers, can dissolve in water
and cause what specific type of stain?
A) Protein browning
B) Oleophilic yellowing
C) Cellulosic browning
D) Acetic acid discoloration
Answer: C) Cellulosic browning
Rationale: Lignin is the natural binder in plant fibers like cotton
and linen. When excessive moisture is used, it can dissolve and
migrate to the surface, oxidizing and causing a yellow or brown
discoloration known as cellulosic browning.
4. Which of the following fibers is oleophilic, meaning it has a
high affinity for oily soils, which can lead to yellowing over time?
A) Wool and Silk
2
,B) Acetate and Triacetate
C) Cotton and Linen
D) Polyester and Olefin (Polypropylene)
Answer: D) Polyester and Olefin (Polypropylene)
Rationale: Oleophilic fibers attract and hold onto oily soils. This
is a characteristic of many synthetic fibers, particularly polyester
and olefin. This attraction can cause them to yellow prematurely
if not cleaned properly.
5. A fabric burns with a blue base and an orange tip, melts, and
smells like celery or sealing wax. The resulting ash is a hard,
rounded, gray-brown bead. This indicates:
A) Nylon
B) Acetate
C) Cotton
D) Wool
Answer: A) Nylon
Rationale: Nylon is a thermoplastic that melts when burned. The
smell of celery or sealing wax and the hard, rounded bead are
key identifiers for nylon in a burn test.
6. What is a primary concern when cleaning silk fabrics?
A) Damage from high alkaline solutions
3
, B) Melting at low temperatures
C) Dissolving in dry solvents
D) Rapid wicking causing wick-back
Answer: A) Damage from high alkaline solutions
Rationale: Silk is a delicate protein fiber that is weakened by
high pH (alkaline) solutions, which can cause it to become brittle.
It also has low resistance to sunlight and perspiration.
7. Microfibers are usually manufactured from which type of
fibers?
A) Nylon and Olefin
B) Polyester and Nylon
C) Cotton and Rayon
D) Wool and Acrylic
Answer: B) Polyester and Nylon
Rationale: Microfibers are ultra-fine synthetic fibers, typically a
split blend of polyester and nylon. Their small size allows them to
penetrate and trap dirt effectively.
8. Which statement about Olefin (polypropylene) fibers is
correct?
A) It absorbs water readily and dries slowly.
B) It is resistant to sunlight and never degrades.
