,I. Fiber, Yarn & Construction Identification
1. A luxury hotel lobby features a dense carpet with long, uncut
loops forming a textured pattern. The construction is:
A. Level loop pile
B. Cut pile saxony
C. Cut-and-loop patterned
D. Frieze cut pile
ANS: A
Rationale: Level loop pile has loops of uniform height and produces a
textured, durable surface common in commercial lobbies.
2. In a residential broadloom, the technician notes a single
continuous strand forming the pile. This yarn type is:
A. Staple fiber yarn
B. Filament fiber yarn
C. Bulked continuous yarn
D. Cable-twist yarn
ANS: B
Rationale: Filament yarn consists of unbroken strands extruded
through spinnerets; staple yarn is cut into shorter lengths and spun
together.
3. A customer’s carpet shows tuft bind failure after cleaning. The
backing is jute-based. Which characteristic of jute contributes?
A. Hydrophobicity
B. High tensile strength when wet
C. Prone to microbial attack when moist
D. Chemical resistance
ANS: C
Rationale: Natural jute backing absorbs water, remains wet longer,
and fosters microbial breakdown of latex adhesive and tuft bind.
4. A loop-pile carpet shows “pile reversal” shading. Which style
type best describes this?
A. Berber

, B. Plush
C. Saxony
D. Patterned cut pile
ANS: A
Rationale: Berber’s loop construction and low twist cause directional
pile shading or pile reversal under changing light angles.
II. Style Types & Finishes
5. A newly installed fifth-generation nylon carpet exhibits
fluorochemical stain resistance. Which finishing process was
applied?
A. Acid-dye resistance fiber modification
B. Soil-release polymer pad application
C. Topical fluorochemical spray
D. Back-coating with acrylic
ANS: A
Rationale: Fifth-generation nylon incorporates acid-dye resistors into
the fiber polymer during extrusion, unlike topical sprays used on older
carpet generations.
6. A patterned sculptured cut-and-loop carpet in a banquet hall
shows difficulty cleaning. The technician should:
A. Use a high-pH pre-spray to lift loop soils
B. Avoid rotary bonnet to preserve pattern definition
C. Agitate at maximum speed for texture flattening
D. Increase extraction temperature to over 200 °F
ANS: B
Rationale: Rotary bonnet can flatten and blur cut-and-loop
definitions; a low-moisture method or gentle extraction preserves
pattern clarity.
7. A cut-pile carpet labeled “multi-level sculptured” indicates:
A. All loops are uncut but varied heights
B. Fibers have multiple dye lots
C. Combination of cut and loop piles at various levels
D. Uniform cut pile with patterned topography
