| Shandong Ludao: Improve Color Fastness |
Color fastness is the core quality threshold for colored paper, dyed paper and high-end gift packaging paper. Unstable color fixing effect often leads to color fading, bleeding and color migration during water wiping, friction and long-term storage. Faded and blurred colors seriously damage product appearance and brand grade, and cannot meet the quality standards of high-end customized color paper. Many traditional dyeing processes rely on excessive dyes to ensure color depth, which causes poor color fastness, easy staining and high chemical residue, failing to meet environmental protection and food-grade safety requirements. Shandong Ludao Energy Technology Co., Ltd. provides professional color fastness upgrading solutions. By adopting high-efficiency environmentally friendly color fixing agents and optimizing dye molecular adsorption and bonding technology, we firmly lock dye molecules on fiber surfaces, effectively preventing color fading and bleeding. The technology improves color uniformity and color durability, reduces dye dosage, and ensures that colored paper has bright color, stable performance and safe and environmentally friendly indicators. |
