Flannel, coral fleece and other fluffy fabrics have become popular choices for many household products for their soft and skin-friendly properties. However, traditional heat transfer technology meets its match on such special fabrics — the ink merely adheres to the fiber surface, and the uncolored white base of the inner layer is fully exposed when the fabric is touched in the reverse direction or stretched, which severely compromises product quality. Obooc heat transfer inks address this industry pain point with its nano-level penetration technology.
Heat Transfer Dye Printing on Special Fabrics such as Flannel and Coral Fleece
Why does such an awkward white exposure issue occur in dye printing on these materials?
Flannel and coral fleece feature unique fiber structures: the former is woven with a twill process with densely arranged villi, while the latter is made of polyester fibers and covered with fine fluff on the surface. While this structure endows the fabrics with a soft hand feel, it forms a natural barrier — ordinary ink molecules have a relatively large diameter and cannot penetrate the fiber gaps to reach the root, only forming a color film on the surface. When the fabric is stretched by external force, the surface color film separates from the inner white base, and the white exposure problem naturally arises.
Ordinary heat transfer dye printing inks on the market result in the awkward issue of white exposure.
Obooc heat transfer printing ink features high penetration in dye printing with no white exposure.
Obooc heat transfer inks boast high permeability with nano-level penetration technology, achieving true color consistency from surface to core, and the printed colors are bright and fade-resistant.
1. 0.3-micron dye particles: With a molecular diameter less than 1/3 of the fiber gap, the particles can penetrate 3 to 5 layers deep along the fiber axis, ensuring uniform color distribution from the surface to the root;
2. Imported Korean color paste formula: High color concentration and strong color reducibility deliver printed patterns with rich layers and a color saturation of over 90%;
3. High color fastness with scratch and rub resistance: The printed colors do not peel off or crack, with a light fastness rating of Grade 8 — two grades higher than ordinary heat transfer inks. It is water-resistant and fade-resistant, demonstrating excellent color stability in outdoor scenarios.
