Product Description
Product Features
The YJA780A series air‑jet looms developed by our company embody independent innovation and a technology‑driven approach. By integrating the strengths of domestic and international loom designs with China’s specific conditions, and leveraging cutting‑edge technologies in their development, the YJA780A series boasts an inherent foundation of superior performance, ensuring its distinctive, high‑quality professional standards. The design philosophy behind the YJA780A series is to provide customers with looms that deliver excellent performance at a competitive price. These machines are engineered to meet the demand for cost‑effective production of high‑quality fabrics, maximizing customers’ return on investment and serving as a reliable edge in today’s increasingly fierce market competition. Recently, the company has introduced an eight‑color weft‑selection model, further expanding the loom’s weaving capabilities and better aligning it with evolving market needs.
The dual‑side braking system has been improved to accommodate high‑speed operation and long‑width weaving, enhancing braking precision and effectively preventing the occurrence of weaving defects such as start‑up marks.
