Selvedge, Raw Denim, and the Craft Revival
Knowledge check
Q1. What does the term 'selvedge' refer to in denim production?
- A. The dye used to create indigo blue color
- B. The self-finished edge of fabric woven on a shuttle loom that prevents unraveling ✓
- C. The back pocket stitching pattern on jeans
- D. The copper rivet placed at the corners of a pocket
Why: Selvedge is the self-finished edge of a woven fabric, created when the weft yarn turns back at the edge. On shuttle looms it forms a tightly woven, clean border that does not fray, which is why it is valued in premium denim.
Q2. Why is raw denim called 'raw'?
- A. It is made from unprocessed cotton fibers
- B. It has not been washed or treated after weaving and dyeing ✓
- C. It is woven without any dye at all
- D. It is sold without any stitching or hardware
Why: Raw denim, also called dry denim, is sold straight from the loom after dyeing, without pre-washing or sanding. The wearer's body and habits gradually create unique fading patterns over time.
Q3. Which type of loom is traditionally associated with producing selvedge denim?
- A. Jacquard loom
- B. Air-jet loom
- C. Shuttle loom ✓
- D. Rapier loom
Why: Vintage shuttle looms, many dating from the mid-20th century, weave a continuous self-finished edge and run more slowly than modern looms. Their narrow fabric width is the main reason selvedge denim is prized by enthusiasts.

- A. Mass producing jeans faster with automated machines
- B. A renewed interest in traditional techniques, heritage fabrics, and small-batch production ✓

Why: Beginning in the 1990s and 2000s, enthusiasts and small makers revived interest in heritage methods such as shuttle-loom weaving, natural indigo dyeing, and hand finishing, valuing authenticity and quality over mass production.
Q5. What is the most common natural dye historically used to color denim?
- A. Madder root
- B. Indigo ✓
- C. Turmeric
- D. Logwood
Why: Indigo is the traditional dye for denim. Its blue color comes from the dye's ability to oxidize on the surface of the yarn, rather than penetrating fully, which gives denim its characteristic fading and blue-white contrast.

- A. About 100 liters
- B. About 1,000 liters
- C. About 3,000 to 7,000 liters ✓

- A. Laser finishing ✓
- B. Bleach soaking
- C. Sandblasting only
- D. Hand-washing in hot water

Q5. Why is recycling denim considered challenging compared to some other textiles?
- A. Denim is made entirely of metal
- B. Denim often contains blended fibers, dyes, and metal rivets that complicate separation ✓
- C. Denim cannot be shredded at all
