Description

Technical Field

[0001] This invention relates to the field of laser marking technology, and in particular to a method and system for laser-producing a whisker effect on jeans. Background Technology

[0002] Laser marking is a method of marking the surface of an object using a laser beam. It can create permanent marks on various materials, including metals, plastics, glass, ceramics, and textiles. This technology uses the high energy of the laser beam to precisely remove the surface layer of a material or alter its properties, forming visible patterns, text, or barcodes. Laser marking is characterized by high precision, speed, and repeatability, and it enables non-contact processing, avoiding material damage. Since laser marking does not require ink or chemicals, it is an environmentally friendly marking method widely used in industrial production, advertising, art, and fashion design.

[0003] The laser-engraving method for creating a whiskering effect on jeans involves using laser technology to create patterns on the surface of jeans that resemble the whiskering wrinkles formed by traditional wear. This technology simulates the natural wear and creases that form on the knees and thighs after prolonged wear, creating a fashionable distressed effect. The purpose of laser marking is to provide a fast, precise, and controllable way to increase the visual appeal of jeans, while also significantly reducing the environmental impact of traditional stonewashing and chemical sandwashing, making laser marking an efficient and environmentally friendly option in clothing design and production.

[0004] While existing laser marking technology has been widely applied in various fields, it still faces some limitations in practical operation. For example, traditional laser marking lacks sufficient flexibility and has limited adaptability to different materials and complex patterns, making it impossible to adjust parameters in real time to meet varying product requirements, thus affecting product uniformity and quality. The lack of an effective real-time monitoring system makes it difficult to detect and correct errors during the marking process promptly, increasing production costs and extending production cycles. These limitations are particularly pronounced in highly variable production environments, such as the rapid iterations in clothing design. These shortcomings hinder the widespread application of laser marking technology, especially in fields that demand high quality and customization. Summary of the Invention
