Abstract
Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. A technique includes using machine learning to create or extract a laser input file for wear pattern from an existing garment. Machine learning can be by a generative adversarial network, having generative and discriminative neural nets. The generative adversarial network is trained and then used to create a model. This model is used generate the laser input file from an image of the existing garment with the finishing pattern. With this laser input file, a laser can re-create the wear pattern from the existing garment onto a new garment.
Claims20
A method of manufacturing a pair of jeans comprising:
- providing a target pair of jeans comprising fabric panels made from a material comprising a warp comprising dyed yarn, wherein the fabric panels are sewn together using thread;
- using a laser with a laser input file as input to create on an outer surface of the target jeans a finishing pattern,
- providing an image of an existing pair of jeans with finishing pattern;
- providing a generative adversarial network comprising a generative neural net and a discriminative neural net;
- forming a model from the generative adversarial network;
- and
- using the model to generate the laser input file from the image of the existing garment with the finishing pattern, wherein the laser input file comprises digital data that is representative of the finishing pattern of the existing garment.
A method of manufacturing a garment comprising:
- providing a plurality of images of a plurality of sample garments with lasered finishing patterns resulting from a plurality of sample laser input files;
- inputting the plurality of images to a generative adversarial network to iteratively train a final model;
- inputting to the final model an image of an existing garment with a desired finishing pattern;
- obtaining from the final model an output of a generated laser input file, which can be used to create the designed finishing pattern;
- providing a target garment comprising fabric panels made from a first material comprising a warp comprising dyed cotton yarn, wherein the fabric panels are sewn together using thread;
- inputting the generated laser input file to a laser;
- and
- using the laser input file to control the laser to form the desired finishing pattern on a surface of the target garment.
A method of manufacturing a garment comprising:
- providing a target garment comprising fabric panels made from a material comprising a warp comprising dyed yarn, wherein the fabric panels are sewn together using thread;
- using a laser with a laser input file as input to create on an outer surface of the target garment a finishing pattern,
- wherein before being exposed to the laser, a cross section of the warp of the target garment comprises a generally round shape, and after being exposed to the laser, a depth of material has been removed, a cross section of the warp comprises a region with a flattened shape relative to the previous generally round shape;
- providing an image of an existing garment with finishing pattern;
- providing a generative adversarial network comprising a generative neural net and a discriminative neural net;
- forming a model from the generative adversarial network;
- and
- using the model to generate the laser input file from the image of the existing garment with the finishing pattern, wherein the laser input file comprises digital data that is representative of the finishing pattern of the existing garment.
