They have six spinnerets with the median spinneret truncated. The polymer solidifies by cooling after being extruded from the spinneret. The tip of each spinneret is called the spinning field. The feature which looked like a tubular spinneret is actually a folded sheet of cuticle. They are defeated by Spider-Man, Spinneret, and Spiderling and left for the police. Depending on the type of spinneret used, either solid or hollow fibers can be formed. However, Kwolek persuaded technician Charles Smullen, who ran the spinneret, to test her solution. The polymer is then melted, spun, by a spinneret into water, or air cooled. In gel spinning a precisely heated gel of UHMWPE is extruded through a spinneret. Spiders produce silk from their spinneret glands located at the tip of their abdomen. A solution consisting of a fiber-forming material and a solvent is extruded through a spinneret. The gland's visible, or external, part is termed the spinneret. Each spinneret has many spigots, each of which is connected to one silk gland.
