Radiation proof composite metallic yarn and weaving method thereof

Abstract

The invention discloses an anti-radiation composite metal yarn comprising textile fiber bundle and metal filament. The diameter of metal filament is 15-80mum. The metal filament and the textile fiber bundle are doubled and twisted. The range of twist is 100-2200TPM. The textile fiber bundle is single yarn, plied yarn or long yarn. The invention also discloses the spinning process for anti-radiation composite metal yarn. At first, metal filaments with the diameter of 20-80mum and textile fiber bundle according with demands are selected and then selected metal filaments and textile fiber bundle are doubled and twisted on doubling and twisting machine. The tension of doubling and twisting is controlled in 15-80g and the twist of doubling and twisting is controlled in 100-2200TPM. Because metal filaments are used, the yarn and fabrics spun with the yarn are smooth. In fabric, longitude and latitude metal filaments are connected with each other in effect to form current loop. It can play a very good anti-radiation effect and improve the wide application of anti-radiation composite metal yarn.

Problems solved by technology

The anti-radiation composite wool is actually a kind of core-spun yarn. The fabric or clothing woven with the wool, because the wool completely covers the metal wires, the metal wires cannot be effectively contacted to form a current loop, thereby reducing the radiation protection. Shielding effect; In addition, during the dyeing and finishing process of this radiation-proof composite wool or the fabric or clothing woven with it, due to the large shrinkage rate of the wool fiber covered on the surface of the metal wire, the metal wire does not shrink, so that the metal wire The arch causes many knots and breaks, and the surface of the woven fabric is not smooth; moreover, this radiation-proof composite wool is a thick yarn, and fine-count yarns cannot be produced using this technology
