Description
Technical Field
[0001] The invention relates to the technical field of laser marking, and in particular to a laser production method for a pair of jeans with a cat's whisker effect and a system thereof. Background Art
[0002] Laser marking is a method of marking the surface of an object using a laser beam. It can create permanent marks on a variety of materials, including metals, plastics, glass, ceramics and textiles. This technology uses the high energy of the laser beam to accurately remove the surface layer of the material or change the properties to form a visible pattern, text or barcode. Laser marking has the characteristics of high precision, high speed and good repeatability, and can produce non-contact processing to avoid material damage. Laser marking does not require the use of ink or chemicals. It is an environmentally friendly marking method and is widely used in industrial production, advertising, art and fashion design.
[0003] Among them, the laser production method of cat whisker effect on jeans refers to the use of laser technology to create a pattern on the surface of jeans similar to the cat whisker wrinkles formed by traditional wear. This technology simulates the wear and creases that naturally form on the knees and thighs after long-term wear of jeans, creating a fashionable wear 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 stone grinding and chemical sand washing, making laser marking an efficient and environmentally friendly choice in clothing design and production.
[0004] Although the existing laser marking technology has been widely used in many fields, it still has some limitations in actual operation. For example, the traditional laser marking process lacks sufficient flexibility and has limited adaptability to different materials and complex patterns, resulting in the inability to adjust parameters in real time during production to adapt to different product requirements, affecting the uniformity and quality of the products. The lack of an effective real-time monitoring system makes it difficult to detect and correct errors in the marking process in real time, which not only increases production costs but also prolongs the production cycle. The limitations are particularly obvious in highly variable production environments, such as rapid iterations in clothing design. The shortcomings affect the widespread application of laser marking technology, especially in the field of pursuing high quality and high customization. Summary of the invention
