A
T-shirt (
T shirt or
tee) is a shirt which is pulled on over the head to cover most of a person's torso. A T-shirt is usually button less and collarless, with a round neck and short sleeves.
T-shirts are typically made of cotton or polyester fibers (or a mix of the two). T-shirts can be decorated with text and/or pictures, and are sometimes used to advertise.T-shirt fashions include styles for men and women, and for all age groups, including baby, youth, and adult sizes.
A life cycle study of one T-shirt brand shows that the carbodioxide emissions from a T-shirt is about 8.8 pounds including the growing of the cotton, manufacturing and wholesale distribution
. The loss of natural habitat potential from the T-shirt is estimated to be 116 square feet.
Making T-shirts is a fairly simple and largely automated process. Specially designed machines integrate cutting, assembling, and stitching for the most efficient operations. The most commonly used seams for T-shirts are narrow, superimposed seams, which are usually made by placing one piece of fabric onto another and lining up the seam edges. These seams are frequently stitched with an over edge stitch, which requires one needle thread from above and two looper threads from below. This particular seam and stitch combination results in a flexible finished seam.
Another type of seam that may be used for T-shirts are bound seams, in which a narrow piece of fabric is folded around a seam, as at the neckline. These seams may be stitched together using a lock stitch, chain stitch, or over edge stitch. Depending on the style of the T-shirt, the order in which the garment is assembled may vary slightly.
These T shirts are very in expensive but they are sold in market with very high prices. One of my Uncle owns a garments factory and it only costs 3 cents to make a T shirt. But the process of making these shirts harms the environment a lot. Because of all the waste and chemicals used in it.
