A Ray of Hope

Apparel sector is driven largely by fashion and fashion requires constant innovation. Opportunities for innovation are constantly being investigated in terms of use of new fibre, different constructions, unique finishes (mechanical / chemical) or innovative styling. No finish would have had such breadth of application as the recent development of Laser Technology.

One of the pioneering works in this area is the launch of the Laser machine at the turn of the millennium in Europe. Laser technology have had varied applications in the past, including in metal cutting/etching, medical applications (eye surgery / kidney stone removal), etc. Adapting to this technology in textile / apparel sector and providing the requisite software support has opened up new vistas for the fashion sector also.

The laser technology allows the reproduction of images onto fabric surfaces, without changing its colour or texture. Additionally, this technology allows the control of the quantity of energy applied. These images demonstrate different effects including pictures, designs, borders and ‘Used Effects’. It can even create local abrasion and fabric breaks. It is applicable to fabric (woven and knitted), leather and to any kind of finish or dye type.

The reproduction of the images onto the fabric surface is the result of the affinity of the dyestuff being modified, dyestuff removal and fabric removal. Fibres and materials such as cotton, linen, wool, leather, lyocell, polyamide, polyester, elastane, lycra etc are all treatable. Since the action is rapid, images are reproduced in seconds with excellent reproducibility and consistency. It is possible to get very contrasting or very smooth designs.

While some of the effects possible on the Laser machine are achievable using traditional techniques such as printing, the former has some unique benefits over the latter. The durability of laser is far superior and since no chemicals are used, there is no issue of colour fastness. No drying is needed since it is a dry process. It is possible, with the Laser technology, to apply onto seams. The design is electronically translated on to the fabric, thus avoiding the need for photolites or serigraphy screens. The machine requires very low maintenance and cleaning. For denims, this technology can produce the used look effect and moustaches with excellent reproducibility and higher productivity. Being an automatic system, chances of human error are slim and furthermore this is a process involving minimal consumables. The laser process uses high resolution that enables reproducibility of very fine images too.

The machine is very simple to use and is very compact thereby requiring minimal space. The finish can be virtually applied to any kind of fabric or garment and can be worked upon through seams too or on areas of varying thickness. Very low maintenance is required and it is an extremely safe, reliable and environmentally friendly system.

In the age where innovation is the mantra for success in the garment industry, the Laser technology offers a big ray of hope. Its versatility in terms of usage avenues and application techniques makes it an investment for good. The only limit to the use of this machine would be one’s own imagination.
