- He came to the field in 1949 from Poland and worked on both tractors and draglines.

- The web is spun from dragline silk; other silks are used to make supporting fibres, threads that attach the web to the branch or the rafter, strands to bind prey, strands to swaddle the developing larvae, and so forth.
- Spider silk - more specifically, the dragline material that frames the radiating spokes of the spider web - features a combination of strength and toughness unmatched by synthetic fibers.
- When they wander outside the burrow entrance, draglines of silk are usually left on the soil surface.
- We tried to account for the possibility that silk composition might vary along a fiber by subsampling a cross-section of the dragline for amino acid analysis.
- Compared ounce for ounce with steel, dragline silk is five times stronger, and much tougher than the Kevlar in bulletproof vests - able to absorb five times the impact without breaking.
- ‘When a fly hits the web, the sticky silk cushions the impact and traps the fly, but the stiff dragline silk absorbs the force and keeps the web intact,’ he said.

- Abstract Molecular elasticity is associated with a select number of polypeptides and proteins, such as titin, Lustrin A, silk fibroin, and spider silk dragline protein.
- Most of the research has focused on a type of silk known as dragline, which spiders use to construct the frame of their web.

- Fig. 3. - Amino acid distribution of three dragline silks collected from spiders on Trinidad, Anguilla, and Gaudeloupe.
- Wolf spiders provide an interesting taxon to examine indirectly mediated predator-prey interactions because, in addition to excreta, they also leave a silk dragline behind them while moving through the environment.
- For example, major ampullate silk, a very tough silk with a tensile strength comparable to Kevlar, is used for the primary dragline or scaffolding of the spider's web.
