AI Technical Summary
Inkjet printing on textiles faces challenges with low rubbing fastness of printed images, leading to color migration, and adding wax to the inkjet ink does not sufficiently reduce the surface friction coefficient or improve abrasion resistance due to wax particles being covered by resin and pigments, also affecting ink ejection properties.
A textile printing ink set comprising an inkjet ink and an overcoat layer-forming liquid, where the wax particles in the overcoat layer have a larger volume average particle diameter than the fixing resin particles, with specific properties to form a wax layer on the printed image surface, reducing friction and improving abrasion fastness.
The ink set enhances the abrasion fastness of textile images by forming a wax layer on the printed image surface, effectively reducing surface friction and improving image durability.
