Laser technology in textile and garment manufacturing

The laser technology for the application in textile finishing process is becoming popular as physical treatment method, especially used in surface modification commonly done by chemical finishing. The use of laser through computer control can help to modify different materials as polymers, woods, and metals thereby altering the physical and chemical properties of the material surface. The laser irradiations are known to create more weak points to the fiber surface in both tensile strength and extensibility compared with untreated fiber. The laser can affect fiber properties in the dye take up exhibiting that the laser induced ripple structure on the fiber surface so as to enhance the dyeing performance of the laser treated polymer fibers. It can also help in improving the visual aspects of denim fabrics especially, and is generally used for cutting on commercial scale at reduced intensities with very fine images controlled by computer system thereby creating identical designs.
