Patent number: 11767635Abstract: Methods and systems are provided for treating a textile substrate. In one example, a method of treating a textile substrate comprises jetting a plurality of treatment compositions from an inkjet printer on to only a treatment area of the textile substrate without being jetted outside of the treatment area, the plurality of jetted treatment compositions each forming a treatment layer over the treatment area, wherein outside of the treatment area the textile substrate is bare of the treatment layers. Jetting the plurality of the treatment compositions includes jetting a pretreatment composition adjacently over the textile substrate, jetting an ink composition over the textile substrate, and jetting a topcoat composition over the textile substrate, and adjusting a composition of the plurality of treatment compositions jetted from the inkjet printer based on a hydrophobicity of the textile substrate.Type: GrantFiled: May 31, 2019Date of Patent: September 26, 2023Assignee: Nike, Inc.Inventors: Christopher Oriakhi, Dave Reynolds, Kurt Thiessen
