| Shandong Ludao: Optimize Dyeing Uniformity |
Color paper and special colored packaging paper have high requirements for dyeing uniformity. In actual production, problems such as uneven color, color streaks, color spots and batch color difference frequently occur due to unreasonable dye addition methods, poor fiber adsorption performance and unstable process parameters. Unstable dyeing quality leads to a large number of defective products, increases production waste, and makes it difficult for enterprises to enter high-end color paper markets. Shandong Ludao Energy Technology Co., Ltd. provides professional papermaking dyeing optimization solutions. We adopt high-efficiency color fixing agents and uniform dyeing auxiliaries to improve the adsorption and dispersion uniformity of dyes on fiber surfaces, avoid local color accumulation and fading, and effectively eliminate color streaks and color difference defects. At the same time, our technology improves color fastness, prevents color fading during water washing and long-term storage, and ensures consistent color performance of batch products. It helps paper factories stabilize colored paper quality, expand differentiated color product lines and enhance market competitive advantages. |
