Flat yarn types are classified according to fiber composition and functional attributes, each influencing market dynamics. Cotton flat yarn remains the baseline product, valued for its softness and absorbency, and holds roughly 35 % of the volume, supported by its dominance in apparel and home‑textile applications. Synthetic flat yarns, chiefly polyester and nylon, capture about 40 % of the market; their low cost, high tensile strength and ease of dyeing drive adoption across technical and industrial uses. Blended yarns, combining natural and synthetic fibers, occupy close to 20 % of the market, offering a balance of comfort and performance that appeals to mid‑range apparel and home‑textile manufacturers. Specialty yarns, such as metallic, elastic and flame‑retardant variants, constitute the remaining 5 %, serving niche markets where aesthetic or safety requirements outweigh price sensitivity. This type‑based taxonomy clarifies how material properties translate into distinct revenue streams within the flat yarn sector.
