Core Strengths
World-Leading Technology
The ultra-fine side-by-side composite fiber technology and equipment developed in recent years ranks among the world-leading levels.
High-Efficiency Multi-End
16-, 20-, 24- and 32-end spinning technologies greatly increase output per position and significantly cut unit energy consumption.
DIO Dual-Filament Technology
DIO technology realizes two filaments per spinneret for composite spinning, nearly doubling output per position.
Semi-Direct Spinning
Composite melt direct spinning combined with high-efficiency multi-end technology has realized semi (dual) direct spinning for sea-island yarn and polyester/polyamide composite yarn.
