Laser finishing method for apparel wear patterns
A patent application (Publication Number: US20230391125A1) describes a method for creating finishing patterns on garments using a laser. The method involves providing an assembled garment made from fabric panels of a woven material with indigo ring-dyed cotton yarn, and obtaining a laser input file based on a target image of a finishing pattern from an existing garment made from a different material. The laser is then used to remove selected amounts of material from the garment's surface at different pixel locations, creating a finishing pattern that mimics the target image. The process allows for the creation of wear patterns commonly found on denim garments, such as combs, whiskers, stacks, or train tracks.
Furthermore, the method includes transferring the laser input file to a laser machine to form the finishing pattern on the garment's outer surface. The laser selectively removes material based on the input file, adjusting the amount removed depending on the desired pixel location's darkness. The method also involves determining values for the laser input file by analyzing the target image and fabric response characteristics, ensuring the finishing pattern on the garment matches the appearance of the target image from the existing garment. Additionally, the method allows for customization of the finishing pattern based on the fabric's characteristics, such as different base fabric colors or weaving patterns, providing a versatile and efficient way to create unique designs on garments.
