Problems solved by technology

At present, there are two main methods to improve the strength utilization rate of fibers in ropes. One is to use spring-type tensioners in the rope production process. Spring-type tensioners use springs to apply tension to fibers so that the yarn and strands are in the same tightness. , but the currently used tensioner is relatively rough in controlling the tension, and cannot accurately measure the tension on the rope yarn and strands, nor can it evenly control the tension
Another method is to make parallel yarn structure ropes, but the method of using parallel yarn structure to improve fiber strength utilization can only be applied to double braided ropes, and cannot be used for single braided ropes
