Seamless garments are created in a single and continuous knitting process that eliminates side seams. This gives more comfortable and better-looking clothes lead to the production of seamless garments. There are some problems in seams. Seams tend to pucker up. Seamless garments are more advantage, which is the garment do not have to be cut and sewn. The seamless machines produce individual garments. There are more than 10 different operations involve in producing a basic garment with seams, but for seamless garments the process involves only one or two operations. At present 8-10 percent of Lingerie products made by seamless methods. Seamless method is improving day to day, its take 25 to 35 % less time to make than cut-and-sew methods. In this method complete garment based on computer programming, that allow different stitching patterns.
The cutting and sewing process is utilized to produce garments, but seamless garments technology creates one entire complete garment with minimal or no cutting and sewing process. As consumers demand more comfortable and better fitting clothes. There are a number of different methods that can be used to produce seamless products. The seamless knits are in tubular shape, which is produce by high elongation yarns, Circular knitting machines were mostly used to make seamless cloths. This leads to saving of production costs up to 35 percent compared to the cut and sew method.
METHODS OF PRODUCTION
Seamless clothing can be produce by following methods:
- Partially machine process (Pasting method)
- Fully machine process
This method and system makes possible a seamless garment finish that is more comfortable than a finish having seams and other imperfections due to the need to tuck/sew edges and joints. The disclosed seamless technology employs a thin film of adhesive that is preferably ether-based polyurethane although other adhesives are acceptable. This adhesive is pre-laminated on at least one surface prior to lamination to another surface under conditions to control adhesion, stretch, breathability, and longevity of the garment.
A fabric laminate comprising at least a first fabric, a second fabric and a heat sensitive adhesive layer, the adhesive layer pre-laminated on the first fabric in the form of a film tacked on the first fabric by application of pressure and temperature less than that required for lamination followed by placement of the adhesive layer between opposed surfaces of the first and second fabrics for adhesively securing said first and second fabrics together along their opposed surfaces in a lamination step by positioning the second fabric on the pre-laminated first fabric and applying sufficient pressure and temperature.
FULLY MACHINE PROCESS
Seamless garment can be produce by following Machines.
- V-bed flat knitting machines
- Circular knitting machines
Seamless clothing machine manufacturing company, Santoni in Brescia is currently leading the market; although other companies like Sangiacomo, Italy and Merz, Germany are also famous players in similar knitting machine technologies.
LATEST DEVELOPMENT: DIGITAL STITCH CONTROL SYSTEM
With the advent of the computer age, the advantages of digitizing knit data became apparent. Moreover, because of the inherent problems of inconsistent loop formation associated with analogue knitting, digital knitting was an obvious necessity for the precision required in shaping. Shima Seiki seized the opportunity by patenting the world's first digital stitch device, the Digital Stitch Control System (DSCS), which was first featured on the SET091FF computerized flat knitting machine back in 1982.
With DSCS, it is possible to control loop length digitally and on-the-fly. Once the DSCS-equipped machine is programmed with the desired loop length, it continuously monitors yarn consumption and adjusts yarn feed and tension through each course to yield consistency throughout the fabric with tolerance to within 1%. Such accuracy achieved by DSCS becomes absolutely crucial to WHOLEGARMENT production.

- Inner wears
- Air bags
- Hand gloves
The development and production of seamless products provides a special performance as comfortable to body and save the production time. Now a days most of the customers want to buy seamless products. Images But these methods have limitations i.e. limited production speeds and product has structural limitations.
