UNSPSC 23121513: Yarn assembly winder

A machine that combines 2 string, 3 string or more of single yarns in consistent tension.

UNSPSC 23121513 Yarn assembly winder is a Commodity code for equipment used to wind yarn onto bobbins, spools, or similar forms during textile manufacturing and production. State and local governments procure yarn assembly winders primarily through school districts and vocational training programs that maintain textile arts curricula, community colleges operating fiber and textile instruction, and occasionally correctional facilities and rehabilitation programs that operate prison industries or occupational training shops. The equipment itself ranges from manual bench-top winders to semi-automated machinery capable of handling multiple yarn weights and fiber types. Procurement under this code typically supports hands-on workforce development in skilled textile trades, educational lab and shop environments, and small-scale production operations within correctional or institutional settings.

The source does not provide recent state and local contract opportunities tagged to this code. Without posted solicitations, geographic concentration and issuing-body activity patterns cannot be characterized. Procurement under commodity codes for specialized production equipment tends to be episodic and narrowly scoped—schools and correctional programs replace or augment textile shop equipment infrequently, often via RFQ or direct purchase rather than formal RFP—so the absence of recent postings does not necessarily signal declining demand. Business development professionals should monitor state vocational education RFQs, community college capital equipment cycles, and state prison industries procurement offices in regions with active textile instruction or production programs.
