Mercerization is a process that enhances the strength, luster, and absorption of fabrics. However, if you want to add flair to your vocabulary, there are plenty of other words to use instead of mercerize. For example, you can utilize "lusterize," which means to give a shining or glistening appearance to something. "Polish," "burnish," and "brighten" work in a similar fashion. You can also try "gloss," which implies a bright, reflective surface or coating. "Enamel" works similarly to gloss, but also depicts a hard, durable finish. Whatever the context, adding these synonyms can add depth and variety to your language.
