Premium Siro Yarn Manufacturer for Bulk Supply

Runtang is an experienced and trusted yarn factory specializing in high-quality Siro yarn, from corporate to private label, we can meet your needs. We use high-end spinning technology and advanced manufacturing equipment to produce Siro yarn with excellent strength, uniformity, and smoothness.

Principle of Siro Yarn Technology

Siro yarn has been developed using a double drafting system, in which two rovings are simultaneously drafted and twisted into a single yarn. Siro yarn optimizes conventional ring spinning, resulting in a yarn with a tight, even surface structure that is less susceptible to pilling and linting during use, and improves the durability of fabrics.

Siro yarn is ideally suited for high-end knitting and weaving applications, balancing the quality and efficiency needs of textile manufacturers to ensure efficient output while remaining cost-effective. At the same time, it produces yarns that satisfy customers.
