• Laser Cutting Machine
As the name suggests, laser cutting machines are equipped with a laser used for cutting fabric layers. Instead of a traditional cutter, these machines employ a special ray of light known as a laser to cut materials like leather and fabric. Laser cutting machines fall under the category of CAD-CAM systems, where a computer system controls the cutting head. This type of cutting machine is widely used in the garment industry to efficiently cut multiple layers of fabric. The laser in this machine not only cuts the fabric layers but also melts synthetic textiles, resulting in a clean finish on the edges. This addresses the issue of fibre fraying at the edges and allows for precise fabric cutting with intricate designs. The high temperature of the laser facilitates the vaporisation-based cutting process, which utilises a carbon dioxide gas laser.
• Water Jet Cutting Machine
The water jet cutting machine works on the principle of high-pressure liquid. A jet of water is used to cut multiple layers of fabrics. This machine is widely used for materials like polyesters, nylons, and other synthetic materials that are not affected by water. In this machine, a fine layer of water jet is sprayed at high velocity through a thin nozzle, which cuts the fabric and fabric layers. This machine generates water with a pressure of up to 60,000 pounds per square inch, which is an exceptionally high-water pressure. This high pressure is what makes it an excellent tool for cutting fabric.
• Plasma Cutting Machine
Plasma cutting was originally developed to meet the growing demand for precise and high-quality cutting standards. However, it is now finding applications in the clothing industry for fabric cutting. This process involves using a high-speed jet with extremely hot ionized gas, specifically Argon, to cut fabric layers. While it allows for faster cutting, it may compromise the quality of the cut. Plasma cutting employs Argon gas, which transforms into plasma at a scorching 30,000 degrees Celsius, to cut one or multiple layers of fabric simultaneously. The nozzle, filled with Argon gas, is used to achieve faster fabric cutting. However, plasma-cutting machines are not commonly used in the apparel industry for cutting fabric.

As a result, the machine is able to sew the fabric pattern efficiently.
• Automated Pocket-Attaching Machine
The production of trousers, jackets, T-shirts, and coats has traditionally involved critical sewing operations, especially when it comes to creating single or double welt pockets. However, this challenge has been effectively addressed through the implementation of automatic pocket-attaching machinery. This type of machine reduces the need for nearly five to six operators. Only one operator is required to manage the machine and the placement of fabric patterns. It can sew together three to four fabric layers and perform four to six different operations as needed. After completing all the operations, single-welt or double-welt pockets can be manufactured within one minute. This automated pocket-attaching machine streamlines the production process.
• Automated Belt-Loop Attaching Machine
In the traditional manufacturing of trousers or jeans, the belt loop attachment is considered a bottleneck area where the operator has to perform three different tasks, producing the belt loop, cutting that loop, and then attaching that loop at the respective position of the garment. But now this task is done with the help of a single machine. The automatic belt loop attaching machine allows to shape and size the belt loop while stitching. This machine performs all the above activities simultaneously. This kind of automation saves time and labour costs while minimising errors.
