The Electronic Jacquard Loom is a core equipment in the high-end weaving field, which achieves large-scale production of complex jacquard fabrics through three core technologies: mechatronics control, high-speed jacquard drive, and intelligent pattern programming. The following systematically elaborates on its core advantages from four aspects: technical characteristics, production efficiency, process adaptation, and industry value.
1、 Core technical features: Breakthrough in precision and efficiency
High speed electronic jacquard driving method: using solenoid valve+linkage mechanism or servo motor direct drive technology, solenoid valve response time ≤ 5ms (traditional mechanical method is 50ms), jacquard needle motion accuracy reaches ± 0.05mm.
Jacquard density: Supports 13440 stitches/meter (ultra fine fabric) to 2688 stitches/meter (coarse fabric), covering the needs of all fields of home textiles, clothing, and industrial fabrics.
Compatibility of intelligent pattern programming system software: Supports importing mainstream embroidery formats such as WILCOM (Japan) and TAJIMA, and can be directly converted EMB/. DST files are jacquard process instructions.
Dynamic correction function: Built in AI algorithm automatically optimizes the interweaving path of warp and weft yarn, reducing the warp breakage rate (by 30% -40%), and increasing the one-time forming rate of complex patterns (such as loop back ≥ 10m) to 98%.
Multi color warp yarn independent control weft selector configuration: standard 32 color electronic weft selector (optional 64 color), achieving 0.1ms level color yarn switching through high-speed photoelectric sensors, meeting high-end process requirements such as double-sided heterochromatic jacquard and gradient blending.
2、 Production efficiency: dual guarantee of speed and quality
Index: Electronic Jacquard Head Machine, Traditional Mechanical Jacquard Machine, Improvement Range
Maximum speed 800 revolutions per minute (yarn count ≤ 40S) 350 revolutions per minute+128%
Pattern complexity supports a large cycle of 200000 stitches, with a maximum flower return of 50000 stitches+300%
Energy consumption 1.2kW · h/kg (cotton fabric) 2.8kW · h/kg -57%
Labor cost: 1 person on duty (automatic inspection), 3 people working together -67%
3、 Process adaptability: full coverage from basic to high-end
Fabric type: lightweight fabric: silk, chiffon (warp density ≥ 180 strands/cm), with micro tension control technology (± 0.5cN) to avoid yarn breakage.
Thick fabrics: denim, canvas (weft density ≥ 80/cm), driven synchronously by dual servo motors, with a torque output of 200N · m, ensuring clear warp yarn opening.
Special craft three-dimensional jacquard: By dividing the warp yarn tension into multiple layers (with a partition number of ≥ 8), it achieves a combination of relief feeling (raised height ≥ 0.8mm) and hollow effect (opening ratio ≥ 35%).
Light sensitive jacquard: Integrated with temperature/light sensitive yarn, combined with electronic jacquard dynamic control, to achieve patterns that change with the environment (such as hidden patterns appearing when the temperature is greater than 28 ℃).
4、 Industry Value: Technological Iteration and Industrial Upgrading
Market response speed sampling cycle: shortened from traditional 7 days to 4 hours (including pattern design → process conversion → trial weaving), meeting the weekly new release needs of fast fashion brands such as ZARA and SHEIN.
Green manufacturing waste rate: Through real-time monitoring system (yarn tension sensor+warp breakage detector), the waste rate has been reduced from 8% to 1.5%, saving over 2 million yuan in annual raw material costs (based on 100 machine clusters).
Industrial collaborative data interface: Open OPC UA protocol, seamlessly integrate ERP/MES system, achieve digital traceability of the entire process from order to production scheduling, process to quality.
