Recently, many researchers have focused on an application of spider silks to stocking, bullet proof jacket and threads from the viewpoint of genetic technology. However, many interesting properties on spider silks have been not made clear even though the genetic technology was developed. Especially, it is necessary to make clear the physico-chemical properties of spider silks in the liquid state. The author tried to dissect spider's bodies and to examine the liquid materials contained in the silk glands. The molecular weight of liquid materials was determined to be about 270,000 even though it was very difficult to determine the molecular weight because of degradation.The elastic modulus was determined for spider silks prepared at different stages of spider's growth. The effects of ultraviolet rays upon silks were also studied. And the mechanical properties of bagworm silks were also studied.

近年来，许多研究人员从基因技术的角度关注蜘蛛丝在袜子、防弹衣和丝线中的应用。然而，尽管基因技术已经发展起来，但蜘蛛丝的许多有趣特性仍不清楚。特别是有必要明确液态蜘蛛丝的理化性质。作者试图解剖蜘蛛的身体并检查丝腺中含有的液体物质。尽管由于降解而很难测定液体材料的分子量，但经测定液体材料的分子量约为270,000。测定了蜘蛛生长不同阶段制备的蜘蛛丝的弹性模量。还研究了紫外线对丝绸的影响。并对结虫丝的机械性能进行了研究。
