1. Which of the following is the primary reason for identifying the fiber
content of upholstery fabric before cleaning?
A. To determine the age of the fabric
B. To calculate the cleaning cost
C. To select the appropriate cleaning method and chemistry
D. To identify the manufacturer
Rationale: Fiber identification is essential because different fibers
have different properties, tolerances to moisture, heat, and chemicals.
Selecting the appropriate cleaning method and chemistry prevents
damage such as shrinkage, dye bleeding, or fiber degradation. Age
and manufacturer are not the primary reasons for fiber identification.


2. Which of the following is a natural protein fiber?
A. Cotton
B. Linen
C. Silk
D. Rayon
Rationale: Silk is a natural protein fiber produced by silkworms.
Cotton and linen are natural cellulosic fibers (plant-based). Rayon is a
manufactured (regenerated) cellulosic fiber. Protein fibers are

generally more sensitive to alkaline cleaners and heat than cellulosic
fibers.


3. Which of the following is a manufactured cellulosic fiber?
A. Nylon
B. Polyester
C. Rayon
D. Acrylic
Rationale: Rayon is a manufactured cellulosic fiber made from
regenerated cellulose from wood pulp or cotton linters. Nylon,
polyester, and acrylic are synthetic (petroleum-based) fibers. Rayon is
sensitive to moisture and can shrink when wet.


4. What is the primary cause of "fuzzing" or "pilling" on upholstery
fabric?
A. Excessive moisture during cleaning
B. Abrasion and mechanical action
C. Improper drying techniques
D. High alkalinity cleaning agents
Rationale: Fuzzing and pilling are caused by abrasion and mechanical
action that pulls fibers to the surface and tangles them into small balls.
This can be exacerbated by aggressive brushing, heavy traffic, or
improper cleaning techniques. While moisture and chemicals can
contribute, mechanical action is the primary cause.


5. Which of the following fibers has the highest absorbency?
A. Polyester
B. Nylon

C. Cotton
D. Acrylic
Rationale: Cotton is a natural cellulosic fiber with high absorbency
(up to 24-27% of its weight). Polyester, nylon, and acrylic are synthetic
fibers with low absorbency (typically less than 4%). High absorbency
makes cotton more susceptible to water-based stains and shrinkage.


6. The term "olefin" refers to which type of fiber?
A. Polyester
B. Polypropylene
C. Acrylic
D. Nylon
Rationale: Olefin is the generic name for polypropylene fiber. It is a
synthetic fiber known for its resistance to moisture, stains, and
abrasion. Olefin is commonly used in indoor/outdoor upholstery and
commercial settings. It has low absorbency and is prone to static and
pilling.


7. Which of the following is a characteristic of nylon fiber?
A. Poor abrasion resistance
B. High abrasion resistance and resilience
C. High absorbency
D. Poor dye affinity
Rationale: Nylon is a synthetic fiber with excellent abrasion resistance
and resilience (ability to recover its shape). It has good dye affinity and
is widely used in upholstery and carpeting. Nylon has low absorbency
but can be prone to static and soiling.

8. Which of the following is a characteristic of polyester fiber?
A. High absorbency
B. Excellent resistance to wrinkling and good color retention
C. Poor abrasion resistance
D. High susceptibility to mildew
Rationale: Polyester is a synthetic fiber known for excellent resistance
to wrinkling, good color retention, and resistance to mildew and
insects. It has low absorbency and good abrasion resistance. Polyester
is commonly blended with other fibers for durability and performance.


9. What is the primary difference between a woven fabric and a knitted
fabric?
A. Woven fabrics are stretchier than knitted fabrics
B. Woven fabrics are made by interlacing yarns at right angles;
knitted fabrics are made by interlocking loops
C. Woven fabrics are always made from natural fibers
D. Knitted fabrics are always made from synthetic fibers
Rationale: Woven fabrics are constructed by interlacing two sets of
yarns (warp and weft) at right angles. Knitted fabrics are constructed
by interlocking loops of yarn, which gives them stretch and flexibility.
Both woven and knitted fabrics can be made from natural or synthetic
fibers.


10. Which of the following is a common problem associated with
cleaning olefin (polypropylene) upholstery?
A. Shrinkage
B. Pilling and static
C. Dye bleeding
D. Mildew growth
