Textile fabric shielding electromagnetic radiation, and clothing made thereof. The textile fabric is made of threads spun of textile fibers, containing cotton, and of steel fibers having a diameter of 6 to 10 .mu.m. The number of mixed yarn threads in warp direction and in weft direction each is 18 to 20 threads per cm, and the yarn fineness of the textile fabric is especially 38 to 40 tex. The textile fabric guarantees a shielding of 20 to 40 dB against electromagnetic radiation at a frequency of 10 GHz. The fabric has the quality of usual clothing, and the clothing thereof is designed with respect to proportions, seams, fasteners, and other special features in a manner such that especially people wearing pacemakers, or hospital and radar personnel, are protected against electromagnetic radiation.
A textile clothing fabric comprising orthogonal crossings between warp threads and weft threads, the threads being made of stainless steel fibers and textile fibers blended together and spun into mixed yarn, wherein the textile fibers comprise cotton fibers and are twined with the steel fibers, the steel fibers measure 6 to 10 micrometers in diameter and constitute a content of 10 to 15% per weight of the mixed yarn, the distribution of the warp threads and the weft threads in the fabric and the composition of the warp threads and the weft threads being substantially the same, the number of mixed yarn threads in warp direction and in weft direction each is 18 to 20 threads per cm, the yarn fineness of the textile fabric is in the range of 30 to 50 tex, a part of the steel fibers is exposed on the exterior surface of the mixed yarn and mutual electrical contact exists between the warp and weft threads at said crossings to form a Faraday cage, such that a shielding by 20 to 40 dB against electromagnetic radiation at a frequency of 10 GHz is established by the fabric.
