To investigate the preparation process and X-ray shielding performance of bismuth oxide/polyurethane/tungsten wire(Bi_2O3/TPU/W) sheathed yarn fabrics, using a spinning solution of polyurethane(TPU) and bismuth oxide(Bi_2O3) with tungsten wire(W) as the core layer, Bi_2O3/TPU/W sheathed yarn was fabricated via core-sheath composite electrospinning technology and subsequently woven into a plain-woven fabric. The effects of Bi2 O3 addition on the surface morphology, chemical composition, mechanical properties, air permeability, and X-ray shielding performance of the nanofiber membrane were investigated. The results indicated that: 1) when the Bi2 O3 addition was 75%,the Bi_2O3/TPU fiber membrane exhibited uniform particle distribution and well-defined morphology; 2) when the diameter of the Bi_2O3/TPU/W sheathed yarn was 0.7 mm, the yarn structure was stable with satisfactory tensile strength.The prepared Bi_2O3/TPU/W sheathed yarn fabric, with a thickness of 1.4 mm, achieved an air permeability of 1 220 mm/s,a moisture vapor transmission rate of 7 040 g/(m2·24 h), and an X-ray shielding lead equivalent of 0.27 mmPb at an incident energy of 83 keV.
