荷兰研究船在海上调查试验期间,分别在大网目拖网的前部,使用粗细不同的三种新纤维网线进行试验.结果发现,能分别减少水阻力6%,9%和15%,相当于可节约相同比例的能量.这种被称作Dyneema RSK60的新纤维网线,能减少水阻力的原因,一是它本身的强度大,二是它的湿结节强度大.其湿结节强度与干结节强度差不多,不象锦纶(PA)网线那样,湿结节强度低于干 During the maritime survey test, the Dutch research vessel used three new fiber nettings with different thicknesses at the front of the large mesh trawl, respectively, and found that they were able to reduce their water resistance by 6%, 9% and 15%, respectively Can save the same proportion of energy.This is called Dyneema RSK60 new fiber network cable, can reduce the water resistance reasons, one is its own strength, and second, its wet nodules strength and wet nodule strength and Dry nodal strength is similar, unlike nylon (PA) cable as wet nodules lower than the intensity of dry
