When two air-jet looms wove electronic-grade cloth at 950 and 900 rpm on the show floor, onlookers saw more than machinery in motion—they witnessed a slice of China's push into high-end composite weaving equipment. At the 29th China International Composites Industrial Technology Exhibition, held in Shanghai from September 1 to 3, such live demonstrations served as the most direct yardstick for technological maturity. Behind the speed lie integrated challenges in control systems, weft insertion mechanisms, and tension management.
Event Background
This year's expo gathered global industry chain players, but the positioning of domestic equipment has quietly advanced. Rifang Textile Machinery showcased four machines covering glass fiber air-jet looms, glass fiber rapier looms, and carbon fiber jacquard rapier looms. Two air-jet models wove 2116 and 1036 style e-cloth respectively. Notably, 1036 style requires higher precision in yarn hairiness and fabric uniformity; achieving stable operation at 900 rpm indicates that the machine has reached a certain level in high-speed vibration suppression and weft flight control.
From an industrial cluster perspective, this breakthrough is not isolated. E-cloth manufacturers in the Jiangsu-Zhejiang region have long relied on imported looms, especially for high-end thin fabrics, where domestic machines were seen as a backup. However, the on-site operating data—950 rpm and 900 rpm—if validated in batch production, could directly challenge the established advantages of overseas brands in high-speed e-cloth weaving. For buyers, this implies potentially lower equipment costs and shorter lead times for delivery and after-sales response.
Industry Impact
During the expo, visitors from more than ten countries including Germany, Japan, South Korea, India, Turkey, and Brazil engaged in technical exchanges focused on machine performance, weaving speed, product adaptability, and process solutions. This interaction reveals two signals. First, overseas customers' interest has shifted from general fiberglass fabric to e-cloth and carbon fiber textiles, indicating an upgrade in downstream applications. Second, domestic equipment makers are replacing static displays with live weaving to build trust through actual operational data—a more intuitive validation for European buyers accustomed to third-party certifications.
The deeper implication lies in the supply-demand transmission logic. Demand from new energy, aerospace, low-altitude economy, and robotics for lightweight structural components is driving the use of carbon fiber prepregs and glass fiber composites, whose upstream is the weaving process. Higher machine speed directly boosts output per unit. For example, switching from 2116 to 1036 style e-cloth involves finer yarns and higher warp density; if the loom cannot maintain high speed, capacity will be significantly constrained. Thus, the 900 rpm figure essentially reflects the machine's adaptability to difficult fabric styles and determines whether composite manufacturers can rapidly expand output during peak order seasons.
For weaving factories, equipment selection logic is changing. In the past, the focus was on price and basic speed; now it is necessary to evaluate the maturity of the process package for specific fabric types and whether the supplier can offer an integrated solution from machine configuration to weaving process. Rifang's tailored introductions for different material characteristics also confirm that the industry service model is shifting from "selling machines" to "selling solutions."
