Swimwear Tricot fiber ratio is described as which of the following?

• A. 70% Nylon 30% Spandex
• B. 60% Nylon 40% Spandex
• C. 90% Nylon 10% Spandex
• D. 100% Nylon

Answer: (C)

In swimwear tricot, the fiber ratio shows how the fabric combines strength with stretch. Nylon provides the places where you need durability, quick-drying wear, and a smooth surface, while a touch of spandex (elastane) adds the elasticity that lets the garment fit snugly and move with you. A blend of 90% nylon and 10% spandex hits the sweet spot: enough elastane to give comfortable stretch and good shape recovery after movement and wetting, while retaining strength, abrasion resistance, and performance in chlorine. If you use more spandex, the fabric becomes very stretchy and may bag out or wear out more quickly in a swimsuit. If you use no spandex at all, the fabric won’t have the required elasticity for a snug, flexible fit. A 90/10 ratio therefore best balances elasticity, durability, and fit for swimwear tricot.
