The Types segment disaggregates HMLS polyester yarn into structural families that shape production economics and downstream pricing. Textured yarns—including false‑twist and air‑jet variants—constitute the largest share, offering bulk and elasticity while preserving modulus, thus serving apparel and home‑textile markets. Filament yarns, both drawn and partially textured, retain a continuous, high‑strength profile, making them preferred for technical and automotive uses where uniform tensile performance is essential. Core‑spun yarns embed a secondary filament (e.g., elastane or high‑tenacity polyester) within a low‑shrinkage sheath, delivering hybrid properties for sportswear and medical textiles. Blended yarns combine HMLS polyester with natural or synthetic fibers (cotton, nylon) to balance hand feel, moisture management, and cost, expanding applicability across mid‑range apparel and interior décor. Each type contributes proportionally to the overall market, with textured and filament categories accounting for roughly 60 % combined, while core‑spun and blended variants capture the remaining 40 %.
