ABSTRACT:
Volatile, organic solvent is removed from textile articles that are provided with thermosensitive fibers capable of visually indicating predetermined maximum temperatures. Textile articles, such as tufted carpet, are heated under conditions effective to evaporate the volatile organic solvent under prevailing pressure conditions, as indicated by the thermosensitive fibers which are woven or tufted directly into and form a part of the textile articles, to remove the solvent from the textile articles.
