四种圆网蜘蛛的主要壶腹腺系统产生的网纤维的力伸长特性已经被确定，并与通过强制吐丝从相同腺体系统获得的纤维的相应特性进行了比较。尽管所有此类纤维的特性差异很大，但平均而言，前者具有 80 g/tex 量级的断裂强度和 35% 的断裂伸长率，这一组合赋予它们极强的抗拉伸失效能力。有一些迹象表明，在没有二氧化碳诱导麻醉的情况下通过强制吐丝获得的纤维具有类似的特性。但是，在完全麻醉下强制吐丝会导致形成韧性较低的纤维，并且往往会产生比来自同一物种的网系泊线纤维更大的形态和物理性能变化。描述了用于制备这些非常小（直径 3 至 5 微米）且因此非常脆弱的纤维样品以及对其进行测量的技术。
The force-elongation properties of web fibers produced by the major ampullate gland systems of four species of orb-web-spinning spiders have been determined and compared with the corresponding properties of fibers obtained from the same gland systems by forcible silking. Although all such fibers are highly variable in characteristics, on the average the former are possessed of rupture tenacities of the order of 80 g/tex and rupture elongations of 35%, a combination that gives them an extremely great resistance to failure in extension. There is some indication that fibers obtained by forcible silking without carbon dioxide-induced anesthesia are possessed of similar properties. But forcible silking under complete anesthesia results in the formation of fibers of lower tenacity and tends to produce an even greater variability in morphology and physical properties than is found among web mooring-line fibers from the same species. Techniques are described for the preparation of samples of these very small (3 to 5-micron diameters) and therefore very fragile fibers and for making measurements on them.
