The definitive tool for POY yarn specifications. Convert between Denier, Tex, and Cotton Count (Ne) with 99.9% precision.
In the global POY (Partially Oriented Yarn) market, density standards vary by region. While Denier is the standard for synthetic filaments like polyester, Cotton Count (Ne) is often preferred in traditional weaving hubs. Our converter uses the standard industrial constants (5315 for Ne and 9 for Tex) to ensure your procurement specs match factory production capabilities.
Denier is the weight in grams of 9,000 meters of yarn, while Tex is the weight in grams of 1,000 meters. Tex is the ISO standard for all types of yarn.
Cotton Count is an indirect system used primarily for spun yarns. Converting filament denier to Ne helps weavers understand the "effective thickness" when mixing materials.
