The garment industry is based on fashion and invariably goes through short fashion cycles. To survive in the market, there have to be regular innovations in colour, style, design, fabric, finish and fit. Automated machinery and IT solutions are key in such a scenario to be competitive and improve business results.
The growth of garment industry in terms of technology adoption can be traced from pedal operated machines in the 60s. The industry moved on to power-operated machines and steam presses in the mid-80s, started assembly line manufacturing in the late 80s and then entered the phase of using computerized machines. The Industry saw a rapid change with the introduction of computerization in the garment industry Automated machines for cutting, sewing, buttonholes, CAD/CAM for pattern making, etc, have brought down the cost of production considerably. As a result, garment companies now focus on technology to be productive and cost-effective at the same time. In terms of advancements in automation, present generation machines have under bed trimmers, which stitch and trim excess thread simultaneously. This means a huge saving on threads and excess manpower, besides this, there are automated machines for stitching collars and cuffs, finishing machines, pressing machines, etc.
Apparel production technologies includes cutting, sewing, fusing, pressing, production, and warehousing employed can vary according to their levels of sophistications. Quality procedures are the main control function of any Apparel Industry. Some of the high-tech machines with high speed and quieter operation offers better quality products within short time. Machine that can combine two or more operations into one helped to increase the efficiency of an operation. Some of them are,
Cutting technology:
Traditionally, long shears and scissor were the only instruments in cutting fabric in garment sector but the scenario has changed a lot, now, High Speed Single/Multi layer cutting machine with
straight/round cutter are must in every garment production unit.
Sewing technology:
A traditional sewing machine is a textile machine used to stitch fabric or other material together with thread. It uses needles to form a stitch by interlocking or inter looping thread through the fabric. Since the invention of the first working sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790,the sewing machine has
vastly improved the efficiency and productivity of fabric and clothing industries.
Most modern sewing machines employ two separate threads to form a special type of stitch known as the lockstitch. The upper thread is led through an eye formed near the point of a needle. The under thread is carried on a bobbin and is linked or locked to the upper thread by means of a rotary or horizontal motion of the bobbin. In a typical machine employing a rotary bobbin, the sequence of operations is as follows. The needle carrying the upper thread moves downward through the material being sewed, and the thread is engaged above the eye of the needle by a hook on the rim of the bobbin. As the bobbin turns, the upper thread is pulled out to form a loop through which the under thread feeds.
The size of the loop is controlled by a tension device on the upper part of the machine. As the needle withdraws, the locked loop formed by the two threads is tightened by the pull of a lever take-up device to form a stitch. In a machine employing a horizontal bobbin held in a freely moving shuttle, the stitch formed is exactly the same. The shuttle moves through the loop of thread as the needle comes down, and then the shuttle returns to its original position as the needle moves up.
Industrial Sewing Machines
Industrial sewing machines are larger and heavier than home machines and are designed to perform only one specific function.
The basic parts of the industrial machine are called the “BIT” or frame . The “BIT” is made of cast iron on a computer numerical control (CNC) machine that creates a casting with appropriate holes for inserting components.
Industrials machines as per design requirement , apply chain or zigzag stitch rather than lock titch. But machines may be-fitted for up to nine threads for strength
Examples are- Single/Multi needle, flat bed/cylinder bed, Sewing machines, Interlock stitch machines ,over lock stitch machines. Computer controlled, direct-drive, high speed, Lock stitch//Zig Zag stitching machine produces high quality seams irrespective of sewing threads and fabrics.

This series of flatbed interlock machines can be used to apply various stitches on different accessories to perform many functional stitches. It is a necessary machinery for a mass production of garments. And is widely in stretch sewing of knitted materials such as under-wares, sports-wares, T-shirts, shorts and knitted fashions, knitted coats and jeans. It is also
applied for functions stitches like hem/collar bound seaming. Lace attaching stitches. fancy stitches.
Pressing technology:
Iron with mini steam generator, Electronic heated steam pressure, Body pressure, Form finisher, Shirt folding tables, Dry cleaning Machines etc.
Steam iron table
Vacuum is useful in two key ways. One, the most effective pressing is done by pulling the steam through the layers. Second, blowing up (via a readily accessible switch) reduces seam imprinting by the iron. This is particularly noticeable if you’re pressing several layers, the iron maps allowances underneath.
This table is reported to be good for napped fabrics like corduroy and velvets because blowing up while pressing doesn’t crush the nap.
Conclusion:
Today the garment industry can not survive without the right technology. Leading Garment units are early adopters of technology for improving fabric utilization and pattern generation. The merging of the capabilities of the electronic sewing machine and the software machine and the software industry is creating an ever – widening range of creative features for the versatile machine. Sewing machines have become individual crafting devices and therefore, seem to have a future as promising as the imagination of the operator.
