Warp refers to the vertical (lengthwise) threads in woven fabric. These are the threads held under tension on the loom, through which the weft threads are woven horizontally.
In Weaving
The basic weaving process:
- Warp threads are stretched on the loom (vertical)
- Weft threads are passed through (horizontal)
- The interlacing creates fabric
Warp threads must be stronger because they're held under tension during weaving.
In Towels
Towel warp threads form the foundation of the fabric. The pile (loops) are created by additional warp threads that are deliberately left loose to form the terry surface.
Warp vs Weft
| Warp | Weft |
|---|---|
| Vertical | Horizontal |
| Under tension | Inserted through |
| Runs lengthwise | Runs widthwise |
| Must be stronger | Can be softer |
