spinneret
spin·ner·et S0642900 (spĭn′ə-rĕt′)n.1. Any of various tubular structures from which spiders and certain insect larvae, such as silkworms, secrete the silk threads from which they form webs or cocoons.2. A device for making rayon, nylon, and other synthetic fibers, consisting of a plate pierced with holes through which plastic material is extruded in filaments.spinneret (ˈspɪnəˌrɛt) n1. (Zoology) any of several organs in spiders and certain insects through which silk threads are exuded2. (Mechanical Engineering) a finely perforated dispenser through which a viscous liquid is extruded in the production of synthetic fibres[C18: from spinner + -et]spin•ner•et (ˈspɪn əˌrɛt, ˌspɪn əˈrɛt)
n. 1. an organ or part by means of which a spider, insect larva, or the like spins a silky thread for its web or cocoon. 2. Also, spin′ner•ette`. a metal plate or cup with tiny holes through which a chemical solution is extruded to form continuous filaments, as of rayon, nylon, or polyester. [1820–30] spin·ner·et (spĭn′ə-rĕt′) One of the small openings in the back part of a spider or silk-producing insect larva, through which the sticky fluid that dries into silk is released.Translationsspinneret
spinneret1. any of several organs in spiders and certain insects through which silk threads are exuded 2. a finely perforated dispenser through which a viscous liquid is extruded in the production of synthetic fibres Spinneret a cap or plate with holes used in machines for making synthetic fibers. Spinnerets are usually made of adhesion- and corrosion-resistant alloys, such as nickel alloys, or of stainless steels. spinneret[‚spin·ə′ret] (engineering) An extrusion die with many holes through which plastic melt is forced to form filaments. (invertebrate zoology) An organ that spins fiber from the secretion of silk glands. (textiles) A metal device with tiny holes through which a solution is forced at high speeds to make fine textile filaments. spinneret
spinneret one of a number of tubular appendages that, in spiders and some insects, exudes silk threads. In spiders the silk is used to make webs, and in insects to make cocoons. Spinnerets in insects and spiders are not homologous structures. |
