UNSPSC 12171508: Vat dye

Vat dyes are essentially insoluble in water and incapable of dyeing fibres directly. However, reduction in alkaline liquor produces the water soluble alkali metal salt of the dye, which, in this leuco form, has an affinity for the textile fibre.

UNSPSC 12171508 Vat dye, a Commodity code, reflects procurement of synthetic colorants used in textile manufacturing and industrial dyeing operations. State and local governments purchase vat dyes primarily through education and workforce development programs, vocational training facilities, and technical colleges that operate textile labs and apparel production programs. The code also sees activity from correctional facilities operating prison industries with textile or garment manufacturing components, and from state procurement offices stocking supplies for ongoing operations at facilities with in-house fabric or apparel production. Issuing bodies are concentrated among state department of education systems, community colleges, vocational schools, and state corrections departments rather than general city or county purchasing offices.

The source material provided contains no records of recent state or local contract opportunities under this code. Without posted RFPs, RFQs, IBFs, or ITBs, geographic concentration and representative recent solicitations cannot be characterized from current activity data.
