A nonwoven textile can be treated with a laser to construct bonding structures between fibers of the nonwoven textile. In examples, the nonwoven textile can have fibers including a material that absorbs electromagnetic radiation emitted by a laser. In addition, based on absorbing the electromagnetic radiation, the fibers can soften, and the softened portions of the fibers can contact one or more other fibers of the nonwoven textile. When the softened portions re-solidify (e.g., after removal of the electromagnetic radiation), the re-solidified portions of the fiber can at least partially encapsulate the other fiber(s) to form the bonding structure between the re-solidified portions and the other fiber(s). In some examples, the bonding structure can reduce the likelihood of the fibers that are associated with the bonding structure from migrating through a face of the nonwoven textile and forming pills.
