An air-jet loom pushing 2116-type electronic fabric to 950 rpm, while another holds steady at 900 rpm on the finer 1036-type—this was the most tangible equipment signal at the Shanghai composites show in early September. Behind these speed figures lies a shift in high-performance fiber weaving from "can do" to "fast and stable," as downstream demand from new energy and low-altitude economy sectors transmits clearly upstream to equipment makers.
High-Speed Weaving Becomes Core Metric for Electronic Fabric
Electronic fabric is a key reinforcement for copper-clad laminates, and its weaving speed directly determines capacity efficiency and cost structure. At the exhibition, Rifeng Textile Machinery's two glass-fiber air-jet looms achieved stable operation at 950 rpm for 2116-type and 900 rpm for 1036-type, demonstrating sustained high speed even under finer yarns and higher warp/weft density. For buyers, higher speed translates directly into greater output per unit time, and in a price-competitive electronic fabric market, equipment efficiency differences quickly show up in product margins.
More notably, the 1036-type's demanding requirements for stability—finer yarns and higher break sensitivity—mean that 900 rpm stable operation is not just a speed marker but a comprehensive test of coordination among let-off, weft insertion, and beating systems. Industry public data suggests that every 10% increase in electronic fabric weaving speed can reduce unit energy costs by about 6%–8%, explaining why high-speed models always draw attention at trade shows.
Downstream Composite Expansion Drives Equipment Iteration
Expansion in new energy, aerospace, low-altitude economy, and robotics is reshaping the demand structure for composite materials. Carbon fiber fabrics are moving from sports equipment to wind turbine blades and flying car frames, while glass-fiber electronic fabric is in tight supply due to growing demand from 5G communications and AI servers. Downstream performance requirements are translating into hard constraints for weaving equipment: higher speed, greater precision, and smarter operation.
The simultaneous display of a glass-fiber rapier loom and a carbon-fiber jacquard rapier loom reflects equipment makers' differentiated development for various fiber characteristics—rapier looms suit multi-variety, small-batch orders, while jacquard mechanisms handle complex structures. This "air-jet plus rapier" combination indicates that a single machine type can no longer cover all composite weaving scenarios; suppliers must offer complete solutions from equipment configuration to process design.
Show Takeaways: What International Buyers Care About
During the exhibition, professional visitors from over ten countries, including Germany, Japan, South Korea, India, Turkey, and Brazil, visited Rifeng's booth, with discussions focusing on equipment performance, weaving speed, product adaptability, and process solutions. European and Southeast Asian clients showed clear interest in follow-up technical cooperation after watching live weaving. This phenomenon reflects a global landscape where electronic fabric capacity is concentrating in Asia, but high-end equipment still relies on a few suppliers.
For Chinese equipment makers, international visitors stopping by signals that the "cost-effective" label is loosening—clients now care more about real output and yield under stable operation. Live-running machines are more convincing than any parameter sheet, which is why platforms like this exhibition hold core value for equipment suppliers: replacing abstract technical indicators with visible weaving results.
Trend Judgment and Practical Advice
From 950 rpm on 2116-type to 900 rpm on 1036-type, Rifeng's live data draws a capability curve. In the next two years, competition in electronic fabric weaving equipment will likely shift from "maximum speed" to "yield and energy consumption at high speed," giving an edge to companies with process data accumulation. Meanwhile, the maturation of carbon-fiber jacquard equipment may push aerospace structural parts from manual layup to automated weaving—the next technological watershed.
