What does spinneret mean?
A spinneret is a small device or organ that produces very fine strands. In textile and industrial fiber manufacturing, it is a perforated cap or nozzle through which a molten polymer is forced, creating continuous filaments that can be collected, stretched, and spun into yarn. The word also has an important zoological meaning: a spider’s spinneret is the structure on the abdomen from which silk is expelled, allowing the animal to create webs, egg sacs, safety lines, and other silk structures. Although the two senses involve completely different materials and processes, they share the idea of shaping material through a specialized outlet. The term is chiefly technical in contemporary usage, especially in manufacturing, and is encountered in both British and American English.
A perforated cap or nozzle through which a molten polymer is extruded as fine continuous filaments for fiber production.
"The material passed through a spinneret before being drawn into thin strands."
This is the standard technical meaning in textile and manufacturing contexts.
An organ on the abdomen of spiders and certain other arachnids that produces and controls the secretion of silk.
"The spider attached a strand of silk to the bark with its spinneret."
This sense is used in zoology and arachnology; spiders generally have several spinnerets, often with differing functions.
Used when referring to multiple devices or anatomical organs.
"Several spinnerets feed polymer into separate lines of fibers."
A spider's spinneret is its own miniature fiber factory, producing the silk threads used for webs and safety lines.

Where does spinneret come from?
The word “spinneret” was formed in the 19th century from “spinner,” meaning one that spins, together with the diminutive suffix “-et.” Its earliest industrial sense referred to a textile mechanism used in spinning. The zoological sense developed by applying the same name to the spider’s silk-producing organ. The word “spin” itself comes from an Old English word associated with twisting fibers into yarn.

How spinneret is actually used
In modern manufacturing, “spinneret” is primarily a technical term. The zoological sense is more specialized and refers to an anatomical organ rather than a machine component.
Easily confused with spinneret
A spinneret is the component that forms and guides filaments, whereas a spinner is a person or machine that spins fiber, thread, or yarn.
