Abstract:
Laser is an energy source, whose intensity and power can be precisely controlled. Laser can help to cut a variety of objects ranging from flexible fabric to rigid and strong metal. LASER is light amplification by stimulated emission of radiation. The most widely used unit to express the wavelength of a laser is in nanometer (nm). Laser light emitted from a laser has four fundamental characteristics: Intensity, Coherency, Mon chromaticity, Collimation which distinguish it from natural light. Lasers are being classified into four classes and some subclasses depending on their wavelength and maximum output power. This classification is based on the severity of the damage to a person when exposed to laser. These classes can be from 1 to 4. In the classes’ 1–4 laser, there are the sub-classes 1M, 2M, 3A and 3B. Lasers have paved their way in the several sections of textile industry such as cutting, engraving, mass customization, bar code scanning etc. Laser equipment are becoming widely popular in textile, leather and garment industries due to the advantage of accuracy, efficiency, simplicity and the scope of automation. In garment production, it can be applied onto different products ranging from home textiles to fashion accessories. The old laser equipment were difficult to run, cumbersome and hard to maintain. However, the modern equipment are easy to operate, simple to learn and easy to maintain. Furthermore, the earlier equipment had several safety issues and they needed replenishment of gasses at regular intervals. The garment production units should take the advantage of applying laser in the post multi-fibre agreement regime to produce more competitive products.
