1. Which fiber test involves burning a small sample to observe flame behaviour,
ash, and odor?
A. Solubility test
B. Microscopy test
C. Burn test
D. Density test
Correct Answer: C. Burn test
Explanation: The burn test (combustion test) is the most commonly used field
method for fiber identification, relying on flame behavior, residue, and odor
characteristics.
2. Wool fiber, when burned, produces a smell similar to:
A. Burning plastic
B. Burning hair or feathers
C. Sweet caramel
D. Vinegar
Correct Answer: B. Burning hair or feathers
Explanation: Wool is a protein fiber and burns with an odor similar to burning
hair or feathers, leaving a crushable black ash.
3. Which of the following fibers self-extinguishes when removed from a flame?
A. Cotton
B. Nylon
C. Wool
D. Rayon
Correct Answer: C. Wool
Explanation: Wool has natural flame-retardant properties and typically self-
extinguishes when removed from the flame source.
4. Nylon fiber, when burned, produces:
A. A gray feathery ash
, B. A hard bead that cannot be crushed
C. A soft crushable bead
D. No residue at all
Correct Answer: B. A hard bead that cannot be crushed
Explanation: Nylon melts and burns, leaving a hard, round bead that cannot be
crushed, distinguishing it from wool and other fibers.
5. Which fiber burns like paper, leaving a gray ash and smelling of burning paper?
A. Polyester
B. Silk
C. Cotton
D. Acrylic
Correct Answer: C. Cotton
Explanation: Cotton is a cellulosic fiber that burns freely, similar to paper,
with a gray fluffy ash and a smell of burning paper.
6. The term 'generic fiber name' as defined by the Textile Fiber Products
Identification Act refers to:
A. A brand name for a fiber
B. The chemical family name given to a manufactured fiber
C. The country of origin of the fiber
D. The weight classification of the fiber
Correct Answer: B. The chemical family name given to a manufactured
fiber
Explanation: The TFPIA requires that manufactured fibers be identified by
their generic name, which describes the chemical family to which they belong
(e.g., nylon, polyester, acrylic).
7. Which fiber is produced from the cocoon of the silkworm?
A. Linen
B. Wool
C. Silk
D. Ramie
Correct Answer: C. Silk
Explanation: Silk is a natural protein fiber produced by the silkworm (Bombyx
mori) as it forms its cocoon.
8. Acrylic fiber when burned will:
A. Self-extinguish and leave feathery ash
, B. Melt, burn, and leave a hard black bead
C. Burn like paper with gray ash
D. Produce a vinegar odor
Correct Answer: B. Melt, burn, and leave a hard black bead
Explanation: Acrylic melts and burns, producing a hot, sputtering flame and
leaving a hard, irregular black bead.
9. Which natural fiber is derived from the flax plant?
A. Cotton
B. Jute
C. Linen
D. Hemp
Correct Answer: C. Linen
Explanation: Linen is made from fibers found in the stems of the flax plant
(Linum usitatissimum).
10. Polyester fiber is identified by which burn characteristics?
A. Burns rapidly, gray ash, paper smell
B. Melts and burns, black smoke, hard bead
C. Self-extinguishes, crushable ash
D. Burns slowly, vinegar odor
Correct Answer: B. Melts and burns, black smoke, hard bead
Explanation: Polyester melts and burns simultaneously, producing black smoke
and leaving a hard, round, shiny bead that cannot be crushed.
11. A fiber that melts away from a flame and leaves a soft, rubbery bead is most
likely:
A. Cotton
B. Silk
C. Nylon
D. Linen
Correct Answer: C. Nylon
Explanation: While nylon does melt from flames, the description of a soft,
rubbery bead before hardening is characteristic of nylon behavior initially.
However, in UFT context, nylon's bead is ultimately hard.
12. Rayon is classified as which type of fiber?
A. Natural protein fiber
B. Synthetic fiber
, C. Manufactured cellulosic fiber
D. Mineral fiber
Correct Answer: C. Manufactured cellulosic fiber
Explanation: Rayon is a manufactured (man-made) fiber derived from
cellulose (usually wood pulp), making it a manufactured cellulosic fiber.
13. Which fiber has the highest natural moisture absorption (wicking) capability
among common upholstery fibers?
A. Polyester
B. Cotton
C. Acrylic
D. Nylon
Correct Answer: B. Cotton
Explanation: Cotton is highly hydrophilic with excellent moisture absorption,
making it more absorbent than most synthetic fibers.
14. Olefin (polypropylene) fiber is best known for which property?
A. High moisture absorption
B. High resistance to moisture and staining
C. Excellent sunlight resistance
D. High heat resistance
Correct Answer: B. High resistance to moisture and staining
Explanation: Olefin/polypropylene is solution-dyed and is highly resistant to
moisture, staining, and most chemicals, though it has poor sunlight and heat
resistance.
15. Which of the following best describes the burn test result for silk?
A. Burns freely, gray ash, paper smell
B. Burns slowly, self-extinguishes, hair smell, crushable bead
C. Melts only, no ash
D. Hard bead, no ash
Correct Answer: B. Burns slowly, self-extinguishes, hair smell, crushable
bead
Explanation: Silk is a protein fiber that burns slowly, tends to self-extinguish,
smells like burning hair, and leaves a crushable, dark residue.
16. The IICRC UFT course categorizes fibers into two main groups:
A. Natural and artificial
B. Protein and cellulosic
