spinning
Let an agent explain spinning as a textile process, distinguish hand, mechanical and filament spinning, relay yarn specifications, standards and workplace safety, and separate it from other senses of the word.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain spinning as a textile process, distinguish hand, mechanical and filament spinning, relay yarn specifications, standards and workplace safety, and separate it from other senses of the word.
The process of drawing out and twisting fibres into yarn or thread, done by hand with spindle or wheel or by machine with ring, open-end, air-jet or vortex systems; the term also covers the extrusion of synthetic filaments from polymer, and spinning is the first stage of textile manufacture after fibre preparation.
What it is for: Making yarn from fibre.
It can be explain hand and machine spinning methods; explain yarn properties and how they are specified; relay standards and workplace safety; distinguish filament extrusion from staple spinning.
Distinguishing features
Draws out and twists fibre into continuous yarn
Staple spinning versus filament extrusion
Twist and count define the yarn
First stage of yarn manufacture
What it looks like
Fibres drawn from a roving or sliver and twisted into yarn on a spindle, wheel or spinning frame.
Physical character
yarn count: tex or Nm linear density - system by fibre and region
twist: tens to thousands turns per metre - by yarn type
ring frame speed: up to about 25000 spindle rpm - industrial
How it is recognised
Fibre becoming twisted yarn
Spindle, wheel or industrial frame
Weaving and knitting use yarn and are later stages; other senses of spinning belong elsewhere

- The registry entry has merged aliases for specific systems and electrospinning; should they be split off?
