Wicking
Some parts are left open → wicking → absorption of dirt.

- When a yarn is able to float → relaxed yarn.
microfiber
- The less interlacing points, the more wicking
……...possibility, the more absorption.
- The less interlacing points, the weaker the fabric.
- You can add a very long float (loop) for extra
absorption, this goes on top of the warp/weft yarns
- Pile yarn = loop velvet/velvetees
3 pick terry towel → slack tension weaving: final beat-up, 2 ground yarns
remain on the same tension. Last beat up, warp yarn is loose because of the
slack beat up. This is how you get loops.

Limitations of 2 yarn systems:
• Structural
• Properties
• Design
Will cover:
• 3, 4 & 5 yarn systems
• Colored weave construction
• Carpet-weaving
3 yarn system
Extra warp systems:
Warp:
• Loop fabrics
• Velvets & Plush (Warp pile fabrics)
• Warp-backed fabrics
Weft:
• Velveteen & Corduroy (Weft pile fabrics)
• Chenille
• Weft-backed fabrics

Woven terry = warp pile fabric. The bottom beam provides the ground warp.
Top beam provides the pile warp. Pile yarns form loops.
- The reed will not move into beat-up position until a number of picks
have been inserted. Result: long warp yarn, without any weft yarns.
- The reed moves forward to beat-up position, beating up picks and
pushing the warp yarns → terry loops.

- 3rd weft is used for beat-up
