Initially the design of the shirt is planned by a specialist (a fashion designer or a tailor) and then the patterns are carefully drawn on the selected cloth. Next the cutting is done using a scissors or using industrial cutting machines particularly built for that purpose in a shirt manufacturing company. Once its cut, a tube section from the front and the back sides are separated for the sleeves. The shirt may or may not contain pockets.
Next, the sewing process starts where the tube section is stitched using an over edge stitching to give a nice finishing. Before the sleeves are attached, they are hemmed to the tube area. When the shirt just isn't in a tube shape and has two different sections, after that the sleeves are usually directly attached to the body.
Once the sleeves are attached the seams of shoulder are stitched which enables to attach the neckband easily. Neck bands may vary according to the pattern of the shirt and in a tube shaped shirt and if you consider the neckband, it is made by aligning the stretched sides to the neckline after which the bands are folded.
This seam is afterwards sewed having an over edge machine. Seams on several cotton shirts would eventually be left visible (with the actual make seams being sewed last). A seam that bound is usually much more quickly achieved by including ribbed fabric straight into the fabric folding machine.
Finally the add-ons such as pockets are stitched. Then inside the pocket, an interlining is tailored in order for the pocket to maintain its shape. There are both the options of sewing a pocket onto the shirt manually or the other option is to use a pocket setter machine.
