A study was carried out into the production of knitted clothing with electromagnetic shielding and the method of measuring electromagnetic shielding. The knitted fabrics with the electromagnetic shielding were made of electric conduction thread. A T-shirt was then sewn using these fabrics. This T-shirt was fitted to a mannequin, along with a receiving antenna and the electromagnetic shielding of the T-shirt was thus measured. As a result, differences such as the coat's length and the height of the collar had an effect on the shielding greater than that of electromagnetic shielding of fabrics themselves. Thus, evaluation of the electromagnetic shielding of the clothing found that not only measurement of the fabric but measurement in the way the fabrics are worn is important. In order to develop clothing with electromagnetic shielding, it is necessary to take the garments shape into consideration.
