纺纱是对纤维集合体牵伸加捻的过程。长丝比短纤维需要的捻度少。
Spinning is the process of drawing out and twisting a mass of cleaned, prepared fibres. Filament yarns generally require less twist than do staple yarns.

The yarn is twisted, exposed to heat which sets the twist in place, cooled and untwisted.
在牵伸过程中连续拉伸长丝，并将其卷绕起来，长丝的强度和弹性会因此而提高。
The process of drawing irreversibly stretches the spun filaments and winds up the stretched yarn. The strength and recoverable extensibility are thereby increased.
