Preparation method of wearable X-ray shielding fabric

Abstract

The invention discloses a preparation method of a wearable X-ray shielding fabric. The preparation method comprises the following steps: S1, master batch treatment of yarns: selecting functional particles such as barium sulfate powder, bismuth oxide nanoparticles and tungsten oxide nanoparticles; plastic particles such as polyethylene glycol terephthalate particles, polyamide particles and polypropylene particles are selected; the functional particles and the plastic particles form master batches of the fibers according to the mass fraction of 1-5wt% and 95-99wt%, and the master batches are subjected to vacuum drying for 24-48h before being used, so that the moisture in the master batches is reduced to be below 20ppm, and the crystallinity of the master batches is improved; s2, preparing yarns: putting the master batch mixture into a melt supply system of a spinning machine, and forming the master batch into the yarns with the content of functional particles in fibers being 3-10wt% by adopting a melt spinning technology; s3, post-processing the yarns: mixing the yarns with different contents according to a certain number of counts, and twisting and plying to form high-strength plied yarns; s4, the high-density shielding fabric is manufactured by adopting the original weave of the woven fabric; the invention provides a method.
