CID CID Materials, Textiles & Finishes 2 — Questions and Answers
Question 1: Thread count in textiles refers to:
- The weight of the fabric per square yard in ounces
- The number of warp and weft threads per square inch (Correct answer)
- The number of colors incorporated into the weave pattern
- The tensile strength rating of the fiber
Correct answer: The number of warp and weft threads per square inch
Thread count measures the number of vertical (warp) and horizontal (weft) threads woven into one square inch of fabric, often used as a quality indicator for sheets and linens.
Question 2: The 'double rub' test for upholstery fabrics measures:
- Color fastness when exposed to UV light
- Moisture absorption and wicking capacity
- Wear resistance and durability under abrasion (Correct answer)
- Flame retardancy and fire resistance rating
Correct answer: Wear resistance and durability under abrasion
The double rub test simulates wear by rubbing fabric back and forth; residential fabrics typically need 15,000+ double rubs, while commercial use requires 50,000+.
Question 3: In fabric weaving, 'warp' and 'weft' refer to:
- The front and back faces of a woven fabric
- The vertical (warp) and horizontal (weft) threads in woven fabric (Correct answer)
- The pattern repeat measurements in inches
- The finishing treatments applied after weaving
Correct answer: The vertical (warp) and horizontal (weft) threads in woven fabric
Warp threads run vertically (lengthwise) on the loom and are held under tension, while weft threads run horizontally and are woven over and under the warp.
Question 4: Which natural fiber is valued for its antibacterial properties and moisture-wicking performance?
- Polyester
- Acrylic
- Bamboo (Correct answer)
- Nylon
Correct answer: Bamboo
Bamboo fabric naturally contains an antimicrobial agent called 'bamboo kun,' making it resistant to bacteria and odor while also being highly moisture-wicking and breathable.
Question 5: A fabric described as 'railroaded' means:
- The pattern runs parallel to the selvage (lengthwise) edge
- The pattern runs perpendicular to the selvage edge (across the width) (Correct answer)
- The fabric features a diagonal railroad stripe design
- The fabric has been industrially distressed for a vintage look
Correct answer: The pattern runs perpendicular to the selvage edge (across the width)
Railroaded fabric has its pattern running horizontally (parallel to the selvage), allowing it to be applied without seams across wide furniture pieces like sofas.
Question 6: Crypton fabric is specified in commercial and healthcare interior design primarily for its:
- Luxurious silk-like drape and appearance
- Significantly lower cost compared to natural fibers
- Built-in resistance to stains, moisture, and bacteria (Correct answer)
- Unlimited custom dyeing capability
Correct answer: Built-in resistance to stains, moisture, and bacteria
Crypton fabric is engineered with a proprietary barrier that repels liquids, resists stains, and inhibits bacterial growth, making it ideal for healthcare and hospitality environments.
