This core yarn is rich in 45% high proportion wool core yarn, which maximizes the natural moisture absorption and breathability of Qianmu; In the research and development of composition ratio, we added 10% Cupro and 17% Acetage. The excellent antibacterial and anti-static properties of Cupro bring the characteristics of easy cleaning and maintenance of Qianmu fabric, while Acetate brings natural antibacterial and temperature regulating yarn properties. Qianmu's innovative composition, with a high proportion of natural fibers, upgrades the traditional core wrapping process of yarn, retaining the soft and elastic texture of the fabric, while also having natural stiffness.
