SELVAGED EDGED DENIM
Selvage edge denim is a high-quality, durable denim with a finished edge created on traditional shuttle (which are only 1.4m wide) looms.This self-finished edge, often marked by a contrasting coloured thread, prevents fraying and unraveling. This older, more meticulous process results in a tighter weave, a more premium fabric, and a higher price point compared to modern, mass-produced denim.Key characteristics
- Self-finished edge: The term "selvage" is a shortened form of "self-edge," referring to a finished edge woven directly into the fabric. This is in contrast to modern denim, which has unfinished edges that are cut from a wider bolt of cloth and can fray.
- Weaving process: Selvage denim is made on traditional shuttle looms, which are slower and produce narrower bolts of cloth (around 36 inches wide).
- Fraying prevention: The woven edge acts as a natural barrier that prevents the fabric from unraveling.
- Distinctive feature: The edge is often identified by a coloured line of thread, frequently red, that runs along the seam.
- Quality and durability: The tighter weave created by the shuttle loom process results in a higher quality, denser, and more durable fabric.
- Craftsmanship: The traditional manufacturing method requires more time and skill, making it a more costly production process.
