respun

Respun is the past participle of the verb respin, meaning spun again. It is used as an adjective or, in some technical contexts, as a noun to describe material that has undergone a re-spinning process. The term is most common in textile engineering and polymer science, where it denotes yarn, fibers, or filaments produced by re-spinning after a prior step.

In textiles and fiber technology, respun yarn can refer to yarn created from reclaimed or recycled fibers that are re-spun into a new thread. This approach can be used to recover value from short fibers, improve uniformity, or adjust properties such as strength, evenness, and texture. The specific spinning method (ring, rotor, melt, or wet spinning) depends on the fiber type and desired characteristics, and processes vary by manufacturer.

In polymer science and materials engineering, respun fibers may be produced by re-dissolving and re-spinning polymer solutions (as in wet spinning) or by re-processing polymer melts to create fibers with tailored mechanical properties. The term appears mainly in technical reports and industry notes rather than in standard textbooks, with definitions varying by context.

Outside technical usage, respun can be used metaphorically to describe a story, idea, or design that has been retold or reworked.
