Thread Count and Sett Measurement Methods
topic
Thread count measurement in woven fabrics uses a pick glass or thread count lens with calibrated area of 1 or 2 centimetres square to count warp and weft threads per centimetre directly from the fabric surface, with the fabric held taut at a consistent tension to represent the standard relaxed thread spacing, supplemented by unravelling and counting threads from a defined sample area for higher accuracy in dense fabrics where individual threads are difficult to distinguish with the pick glass.
Role
Provides the fundamental fabric specification parameter that quantifies the construction density and determines fabric weight per unit area when combined with yarn count data, with thread count being the primary reported specification for cotton bedding fabrics and the essential input for fabric construction calculations, process engineering, and quality verification that confirms delivered fabric meets the thread count specified in the purchase order.
