AI Technical Summary
Existing flame-retardant yarns are prone to shrinkage at high temperatures and have insufficient interfacial bonding strength, which leads to deformation of the fabric structure and degradation of mechanical properties.
It adopts a core-spun yarn structure, with the core layer being modified basalt fiber and the sheath being a blended yarn of polyimide fiber and flame-retardant acrylic fiber. The fiber surface roughness and oxygen content are enhanced through low-temperature plasma treatment, and a core-sheath structure is formed by combining the sirospinning process.
It achieves low thermal shrinkage and excellent flame retardant properties of yarn at high temperatures, improves the structural stability and mechanical properties of yarn, and reduces raw material costs.
