Covered Yarn Production Technology in China
China's covered yarn industry has rapidly upgraded from traditional manufacturing to intelligent production. Today, leading factories use advanced automatic covering machines, electronic tension control systems, and real-time quality monitoring technologies to ensure consistent yarn performance.
The production process usually includes:
Raw Material Selection
High-quality spandex, nylon, polyester, and rubber filaments are selected according to end-use requirements. Stable raw materials directly affect elasticity, recovery performance, and dyeing consistency.
Precision Covering Process
Modern covering machines control yarn tension, wrapping speed, and twist density to maintain uniformity during production. This is especially important for seamless garments and compression textiles.
Quality Inspection
Each batch normally goes through tensile strength testing, elongation testing, evenness inspection, and package appearance checks before shipment.
Manufacturers like Kangjiesi continuously invest in advanced equipment to maintain product consistency in global markets.
