Barium sulfate/regenerated cellulose composite fiber with X-ray radiation resistance

Abstract

In this article, submicron barium sulfate particles, as the radiation-resistant component, were incorporated into regenerated cellulose spinning solution. Then a series of X-ray radiation-resistant fibers were fabricated via a primarily industrialized wet-spinning trail, and the resultant fibers were knitted into fabrics by knitting loom. The morphology and structure of the fibers were studied with the aid of scanning electron micrography, Fourier-transform infrared spectroscopy, and X-ray diffraction. The composite fibers exhibited reasonably good properties, which met the criteria of mechanical requirements of commercial textiles-dry breaking strength and elongation (>1.5 cN/dtex and 26%) and wet breaking strength and elongation (>1.4 cN/dtex and 22%) and permanent laundry-resistant abilities even after being washed 20 times. An effective and feasible X-ray radiation-resistant method, the medical digital X-ray photography system, was proposed to evaluate the radiation resistance of the composite fiber and its fabric. The X-ray attenuation ratio of the sample tended to increase with increasing barium sulfate content and finally reached a dose of a 0.1 mmPb lead equivalent. Therefore, these fibers and fabrics can be utilized as the base materials for X-ray radiation-resistant lightweight apparel and detective surgical yarn.

Enhanced Adsorptive Properties and Pseudocapacitance of Flexible Polyaniline-Activated Carbon Cloth Composites Synthesized Electrochemically in a Filter-Press Cell

“…A higher magnification image (Figure 2b) reveals that each fiber has a ridge surface with grooves parallel to the fiber axis direction. This shape is typical of wet spun viscose fibers [35] used as precursor material in the activated carbon fabric manufacture. At an electropolymerization time of 10 min, PAni can already be discerned on the surface of ACC (Figure 2c–d).…”

Novel Biobased Textile Fiber from Colombian Agro-Industrial Waste Fiber

“…All images exhibit a rough surface with a granular topography that is typical of viscose rayon morphology [ 31 ]. Filaments presented a wrinkled surface owing to the coagulation of the material [ 35 ]. In both cases, we can see that the cross section presents cavities formed generally by the solidification of the viscose [ 36 ].…”

“…On the other hand, the cross section of the fibers presents a lobed or circular serrated (jagged) shape with a highly rough/striated surface; this is characteristic of the coagulation process of viscose rayon fibers because this is found first on the surface and delays coagulation within the fiber [ 35 , 37 , 38 ].…”

The gamma radiation shielding effectiveness of textured steel yarn based fabrics

“…The results showed that, at 60% weight ratio, 1.55 mm bismuth embedded coating could attenuate 90% of X-ray photons at the 100 kV level, while the required thickness of a tungsten embedded coating was 1.73 mm for the same protection level. Qu et al fabricated a series of X-ray radiation-resistant fibres via a primarily industrialized wet-spinning trail, and knitted the resultant fibres into fabrics by knitting loom [9]. The X-ray attenuation ratio of the sample tended to increase with increasing barium sulphate content and finally reached a dose of a 0.1 mm thick lead equivalent.…”

“…1 -I 0 initial intensity was counted without a fabric sample in air media. 2 -I intensity was counted while the sample is between detector and source Decay Scheme of Am-241[9]…”
