The High Speed Edgeless Double Twister is the core equipment for modern textile industry to achieve efficient, low consumption, and flexible yarn twisting. Through innovative structural design and intelligent control system, it breaks through the efficiency bottleneck and process limitations of traditional double twisting machines. The following systematically elaborates on its technical characteristics from three aspects: core performance, technological breakthroughs, and industrial value.
1、 Core performance breakthrough
Ultra high speed operation capability and spindle speed limit: The spindle speed can reach 18000-22000r/min (traditional models have 12000-15000r/min), and the efficiency of single spindle twist application is increased by more than 50%.
Dynamic balance technology: using magnetic levitation bearings or air bearings (vibration value ≤ 0.1mm/s), combined with an online dynamic balance correction system, to ensure that the yarn tension fluctuation is less than 0.5cN during high-speed operation.
Innovative zero winding edge design for edgeless winding structure: By using a hyperbolic yarn guide and dynamic tension compensation device, the phenomenon of yarn edge accumulation during traditional double twisting machine winding is eliminated, and the uniformity of cylinder density is improved by 30% (density deviation ≤ 3%).
Case comparison: When processing 30S pure cotton yarn, the traditional machine model has a protrusion height of 5-8mm on the end face of the winding tube, while the edgeless machine model can be controlled within 1.5mm, reducing the breakage rate of the subsequent winding process by 40%.
Intelligent tension control system closed-loop feedback mechanism: using high-precision pressure sensors (resolution 0.01cN) and servo motor-driven tension wheels, real-time adjustment of yarn tension (fluctuation range ± 1cN), suitable for sensitive yarns such as high elastic core yarns and low denier nylon.
Data verification: When processing 75D/72F nylon elastic yarn, the traditional model has a breakage rate of 12 times per 10000 meters, while the edgeless double twisting machine can reduce it to 2 times per 10000 meters through intelligent tension compensation.
2、 Process and efficiency improvement
Technical dimension: Traditional double twisting machine, high-speed and borderless double twisting machine, performance leap
Single ingot output of 8-10kg/shift 15-18kg/shift, efficiency increased by 87.5%
Energy consumption index 0.35kW · h/kg 0.22kW · h/kg Energy saving 37%
Change variety time 45-60 minutes 8-12 minutes Flexible production efficiency increased by 5 times
Equipment occupies 1.8 square meters per ingot, 1.2 square meters per ingot, and the utilization rate of unit production capacity space is increased by 50%
3、 Industrial Value and Application Scenarios
High value-added yarn production of fine denier multi strand yarn: can stably process 50D/144F ultra fine denier nylon yarn (single filament diameter only 11 μ m), yarn hairiness index ≤ 2.5 (traditional models are 4.8), meeting the demand for high-end outdoor clothing waterproof and breathable film composite.
Functional composite yarn: precise coverage of spandex core yarn and outer fibers is achieved through a dual channel feeding system, with an spandex content error of ≤± 0.5%. It is used for seamless underwear, pressure socks and other elastic fabrics.
Green manufacturing and cost optimization reduce energy consumption: By adopting permanent magnet synchronous motors and energy recovery systems, a single unit can save over 30000 kWh of electricity per year (when operated for 8000 hours per year), reducing CO ₂ emissions by 23 tons.
Raw material utilization rate: The edgeless winding structure reduces the amount of residual yarn in the tube by 60%, and combined with the intelligent yarn breaking self stopping function, the raw material waste rate is reduced from 3% to 0.8%.
Intelligent and digital fusion AI fault prediction: By using 12 sensor data such as vibration, temperature, and current, it can provide 24-hour advance warning of bearing wear, belt looseness, and other faults, and the overall equipment efficiency (OEE) has been improved to 92%.
Cloud based process library: supports cloud storage and quick retrieval of 5000 yarn process parameters, shortening the development cycle of new varieties from 72 hours to 4 hours.
