The most common printing technique for synthetic products is sublimation printing. Sublimation printing uses ink with specific dyes to print on treated paper. Then, the printed image is transferred to the fabric under controlled conditions with a set time, pressure, and temperature. The heat sublimates the ink from a solid into a gas that migrates through the fabric fibers and permanently dyes the fabric.
However, the current sublimation process cannot be used on natural fabrics, such as cotton, silk, or linen. For these natural fabrics, a digital printing process is used. This process is more complex and more expensive than the sublimation process because it involved additional steps for the natural fabrics.
Your challenge is to create an innovative printing solution that can be applied to natural fabrics to improve the efficiency of the printing process and produce a high-quality end product.
One way to improve the efficiency of the current process is to eliminate one or more of the steps inherent in the direct printing process on natural fabrics (i.e., pre-treatment, post-treatment and washing). This could minimize the energy, water, and consumable expenditures required and shorten of the production cycle for printing of natural fabrics.
