What does spinnerets mean for kids?
Kids Encyclopedia Facts. A spinneret is the part of a spider’s body that makes its silk. Spiders have one, two, or three pairs of spinnerets. The spinnerets are usually close together.
What mean by spinnerets?
1 : an organ (as of a spider or caterpillar) for producing threads of silk from the secretion of silk glands. 2 or spinnerette : a small metal plate, thimble, or cap with fine holes through which a chemical solution (as of cellulose) is forced in the spinning of man-made filaments (as of rayon or nylon)
What is spinneret chemistry?
A spinneret is a device used to extrude a polymer solution or polymer melt to form fibers. Streams of viscous polymer exit via the spinneret into air or liquid leading to a phase inversion which allows the polymer to solidify. The fiber production process is generally referred to as “spinning”.
How many holes can a spinneret have?
Conventional spinneret orifices are circular and produce a fiber that is round in cross section. They can contain from about 50 to 110 very small holes. A special characteristic of their design is that the melt in a discharge section of a relatively small area is distributed to a large circle of spinnerets.
Do male spiders have spinnerets?
When the time for mating approaches, the male constructs a special web called the sperm web. The silk for it comes from two sources, the spinnerets at the end of the abdomen and the spigots of the epigastric silk glands located between the book lungs. Males generally wander more extensively than females.
Which fiber is produced by a spinnerette?
A spinneret is a piece of industrial equipment used in the production of polymer fibers. Using an extrusion process, a facility can force liquid polymers through the spinneret, turning them into long strands that harden into usable fibers.
What is the function of spinnerets?
Spinnerets are used for the production of silk, a complex fiber that is used to make webs, draglines, egg sacs, and more. To better understand this process, we have to go into the body of the spider. Within each spider’s abdomen are a variety of silk glands which can vary in number depending on the species.

Do Daddy Long Legs poo?
They also don’t have fangs like spiders do, they have little pincers instead. Unlike other arachnids, they are capable of consuming solids rather than just liquids. Some of them are even omnivorous, eating plants, fungi and various droppings, technically known in these parts as “poo”.
