Laser cutting after they were introduced in the 19th century, the fashion designers are widely adopting laser cutting in garment manufacturing. In synthetic fabrics, laser cutting produces well-finished edges as the laser melts and fuses the edge, which avoids the problem of fraying produced by conventional knife cutters. Furthermore, use of laser cutting is increasingly used for leather due to the precision of cut components.

In fashion accessories such as jewellery, laser cutting can be used to produce new and unusual designs to produce a fusion of apparel design and jewellery style. In laser cutting a laser is used to cut the fabric into the desired pattern shapes. A very fine laser is focused on to the fabric surface, which increases the temperature substantially and cutting takes place due to vaporization.

Normally gas lasers (CO2) are used for cutting of fabric. The cutting machine includes a source of laser, a cutting head fitted with mirrors to reflect the laser beam to the cutting line, a computer to control the entire system and a suitable mean for removing the cut parts. The application of inert gases (N2, He) during cutting prevents the charring and removes debris and smoke from the cutting area. Like the mechanical cutting devices, a laser beam does not become blunt and need sharpening. Automatic single ply laser cutters are faster (30–40 m/min) than automatic multiple ply knife cutters (5–12 m/min). However, while cutting multiple plies, knife cutters are faster per garment cut and also cheaper. The limitation of laser cutting is the number of lays of the fabric that can be cut by the beam. Best result is obtained while cutting single or a few lays, but the accuracy and precision is not obtained with several plies.

In addition there is a chance of the cut edges to be fused together especially in case of synthetics. In some cases the sealing of the edges of cut patterns and sewn garment parts is essential to prevent fraying, where the laser plays the role. As in garment production facilities emphasis is given in multiple lay cutting, the laser cutting seems unlikely to become widespread. However, it is successfully used in cutting of sails where single ply cutting is the norm and a slight fusing of the edge of synthetics and woven materials is desirable. In addition, laser cutting is used in some areas of home furnishing. Laser cutting is cheaper compared with the traditional cutting methods. Furthermore, as the laser cutting doesn’t have mechanical action, high precision of the cut components at high cutting speed are feasible.

The laser cutters are safer and include simple maintenance features, which can be operated for longer duration. The laser cutters can be integrated to the computer technology. It can produce the products at the same time when designing in the computer. Laser cutting machines have faster speed and simpler operation. Laser cutting machines are suitable for cutting textile fabrics, composites and lather materials. They can operate for a wide range of fabric, which is not possible with die cutters. Hence, laser cutting machines are gradually been accepted in garment manufacturing.

Color Laser Marking Machine used to coloured parts are commonly used from decorative applications in a wide range of consumer goods and marking of these parts is generally achieved though the removal of the coloured anodised layer to reveal the base aluminium material either a white or silvery mark depending on process conditions. Commonly used in gift-ware and consumer goods, alphanumeric and marketing logos are typically marked.

The use of lasers for colour marking is not a particularly new technique as it has been recognized for over 10 years. This technique was originally identified as a viable process for use on craft metal work and jewellery. However, the process has had very little commercial impact in the intervening years. There is now a greater interest in this process as manufacturers of consumer goods are looking for new techniques and finishes to provide product differentiation. This application note looks at a variety of materials that are colour mark-able including titanium and stainless steel, and explores the benefits and parameters of the pulsed fiber laser in relation to this application area.
