Anionic dyes are a class of synthetic colorants frequently used across multiple industries, primarily the textile industry. They are defined by their chemistry: when dissolved in an aqueous (water-based) solution, they dissociate to yield a negatively charged, colored ion . This negative charge determines their application, as they form ionic bonds with positively charged sites (cationic sites) on the fibers, resulting in a strong and durable color.
Annealing is described as controlled heating and cooling process designed to relieve internal stresses introduced in a glass container during and immediately after glass container formation. Annealing point, meanwhile denotes the specific temperature in which internal stresses built up during glass container formation are substantially relieved in 15 minutes.
