Step 1: Understanding terry towel construction.
Terry towels are designed to have high absorbency, which is achieved by creating looped pile structures on the fabric surface.
Step 2: Type of pile used.
In terry towels, the pile is formed by warp yarns, not weft yarns. These warp pile yarns form loops on the fabric surface.
Step 3: Yarn arrangement.
A terry fabric typically consists of one series of warp yarns (ground and pile warp together) and two series of weft yarns (ground wefts) to bind the pile securely.
Step 4: Conclusion.
Hence, a terry towel is a warp pile structure with one series of warp and two series of weft yarn.
