Overview
SIST ISO 1139:1998 - Textiles – Designation of Yarns is an international standard that specifies two primary methods for indicating the composition and construction of yarns. Developed by the Institute for Standardization of Slovenia (SIST), this standard ensures consistent and clear communication across the textile industry regarding the characteristics of single, folded, cabled, or multiple wound yarns. By standardizing yarn notation, including linear density in the Tex System, number of filaments, and yarn construction features, SIST ISO 1139:1998 supports precise specification and quality control in manufacturing, trade, and textile testing.
