When selecting this fabric, the ratio of nylon to polyester determines the hand-feel and durability. A higher nylon content increases softness and elasticity, while more polyester enhances wrinkle resistance and colorfastness. You must specify the thread count (e.g., 228T, 290T) and denier (e.g., 40D, 70D); higher density translates to a more luxurious luster and better windproof properties. For high-end apparel, prioritize high-multi filaments to ensure a silk-like texture without the fragility of real silk.
