The KV2020 model is the result of years of dedicated efforts by the R&D team of New Heli Company, specifically designed for the production of long and fine filaments, achieving a new level of spindle speed performance in the industry. The speed of the twisted strand can reach up to 10000 revolutions per minute. Producing long filament threads under 150D can double the production capacity, making it an ideal twisting equipment for high-end long filament sewing thread manufacturers to update and upgrade.
