Fashion Designer Materials & Techniques 2 — Questions and Answers
Question 1: Which weave structure produces a fabric with a diagonal rib visible on its surface?
- Plain weave
- Twill weave (Correct answer)
- Satin weave
- Basket weave
Correct answer: Twill weave
Twill weave interlaces yarns in a stepped diagonal pattern, creating a characteristic diagonal rib on the fabric surface.
Question 2: What does the term 'bias cut' mean in garment construction?
- Cutting fabric along the selvage edge
- Cutting fabric at a 45-degree angle to the grain (Correct answer)
- Cutting fabric parallel to the weft yarns
- Cutting fabric with a rotary blade only
Correct answer: Cutting fabric at a 45-degree angle to the grain
Bias cut refers to cutting fabric at a 45-degree angle to the warp and weft, allowing the fabric to stretch and drape more fluidly.
Question 3: Which fiber is produced by the silkworm Bombyx mori?
- Wool
- Cashmere
- Silk (Correct answer)
- Angora
Correct answer: Silk
Bombyx mori silkworms spin cocoons of continuous filament silk that is unwound and woven into luxury textile.
Question 4: What is 'grainline' in fabric and pattern making?
- The decorative print direction
- The direction parallel to the warp (lengthwise) yarns (Correct answer)
- The finished edge of the fabric
- The crosswise stretch direction
Correct answer: The direction parallel to the warp (lengthwise) yarns
Grainline refers to the direction of the warp yarns running parallel to the selvage, and pattern pieces are typically aligned along it for stability.
Question 5: Which finishing technique permanently sets pleats or creases in synthetic fabrics using heat?
- Calendering
- Heat-setting (Correct answer)
- Mercerizing
- Singeing
Correct answer: Heat-setting
Heat-setting uses controlled heat to fix the molecular structure of thermoplastic fibers like polyester, permanently locking pleats or pleated textures.
Question 6: What is 'ease' in garment construction?
- The seam allowance added around the pattern
- The extra fabric allowance added beyond body measurements for comfort and movement (Correct answer)
- The hemline adjustment for different heights
- The dart intake amount
Correct answer: The extra fabric allowance added beyond body measurements for comfort and movement
Ease is the intentional difference between body measurements and garment measurements that allows for comfortable movement and wearing.
Question 7: Which natural fiber is known for its hollow core that provides excellent insulation?
- Cotton
- Linen
- Wool (Correct answer)
- Jute
Correct answer: Wool
Wool fibers have a naturally scaly, hollow-core structure that traps air and provides excellent thermal insulation even when damp.
