我们克服了从蜘蛛身上拉出长长的拖丝、捻成捆的拖丝的困难，成功地制作了小提琴的琴弦。研究发现，扭转可以改变纤维的横截面形状，使其由圆形变为多边形，并优化了填料结构，使纤维之间没有开口，从而提供了机械强度高、弹性强的线材。小提琴泛音的蜘蛛弦信号峰值在高频处相对较大，产生柔和而深沉的音色。这种优选的音色被认为是由于独特的多边形填料结构，这为开发新型材料提供了宝贵的知识。
We overcome the difficulties in pulling long draglines from spiders, twist bundles of dragline filaments, and succeed in preparing violin strings. The twisting is found to change the cross section shapes of filaments from circular to polygonal and to optimize the packing structure with no openings among filaments providing mechanically strong and elastic strings. The spider string signal peaks of overtones for the violin are relatively large at high frequencies, generating a soft and profound timbre. Such a preferable timbre is considered to be due to the unique polygonal packing structure which provides valuable knowledge for developing new types of materials.
