The Force-Elongation Behavior of Web Fibers and Silks Forcibly Obtained from Orb-Web-Spinning Spiders
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 correspondingExpand

Viscoelastic Behaviour and Wet Supercontraction of Major Ampullate Silk Fibres of Certain Orb-Web-Building Spiders (Araneae)
1. The axial retractive stresses that cause the supercontraction of wetted major ampullate silk fibres and the stresses developed upon reextension from the supercontracted condition are quantifiedExpand

A Physico-Chemical Study of the Supercontraction of Spider Major Ampullate Silk Fibers
Methanol, ethanol, and isopropanol do not radially swell or produce supercontrac tion (SC) of spider major ampullate silk fibers. Their aqueous solutions do so at rates associated with waterExpand
