摘要
Conventional "pearl gray" chrome green mineral dyes require a double decomposition process for depositing green chromium oxide in cellulosics. By forming a unique alkaline complex of a chromic chloride with ammonium oxalate and zirconyl ammonium carbonate, a single dye bath is produced, enabling the dyes to apply the "pearl gray" chrome green mineral dyeing by a simple pad, dry, cure, and wash procedure. The dyeings are uniform and the cellulosic is not tendered or physically degraded. Not only does this invention reduce processing steps, but it eliminates the conventional problem of tendering resulting from drying the chromic chloride on cellulosics prior to processing through a second bath of soda ash and soap. The invention makes it possible to prepare a modified chromic chloride stock solution that can be used for either the conventional "pearl gray" processing or the single bath process described above.
