Laser marking features high marking precision, fast speed, clear marking, and the ability to print various characters, symbols, and patterns on the flat and curved surfaces of all kinds of products. It has a very wide application range. It can not only be used for fine marking on materials such as glass, ceramics, plastics, metals, and jewelry, but is also gradually being adopted in the processing of textiles and clothing.
Common laser processing techniques in textile processing include laser cutting, laser marking, and laser embroidery, etc. The main principle is: to irradiate a laser beam onto the surface of the workpiece, using the ultra-high energy of the laser to cut, gasify the material and change the surface properties of the workpiece. In the field of clothing, the main marking techniques are reflected in laser marking on ready-to-wear garments, laser washing on denim, laser marking on leather and fabrics, and laser marking on stickers and labels, etc. Through laser marking, we have created the various exquisite patterns on our clothing today.
Clothing usually comes into direct contact with human skin, so the fineness of the clothing patterns is of vital importance. Laser processing uses high-energy-density laser beams to cut and engrave on fabrics. It is a highly efficient non-contact processing method that does not affect the quality of the fabric itself.
At the same time, the laser processing are smooth and clean, without burrs or rough edges. More importantly, the deeper significance of laser application for the clothing industry lies in reducing the use of chemical dyes and water, saving water and reducing emissions by over 50%, and greatly improving environmental quality. In the manufacturing of denim clothing, using lasers to engrave denim can produce fabric with a washable effect without water. Through the laser irradiation of numerical control, the dye on the surface of denim can be vaporized, and patterns that never fade can be created on denim fabric.
The combination of new information technology and machinery has led to the wide application of laser marking technology in the clothing industry, it is reliable in performance, economical and energy-saving.
