I'm reaching out to inquire about the process for dyeing white PVA material to achieve a light grey color. Specifically, I'm interested in understanding the types of dyes that are best suited for this material, as well as any recommended techniques or methods that would yield consistent results. Additionally, if there are any specific temperature or time parameters we should follow during the dyeing process, that information would be extremely helpful. It's essential for us to maintain the integrity and properties of the PVA while achieving the desired color. Your expertise in this matter would be greatly appreciated, and I look forward to your detailed response.
