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.

Polyethylene terephthalate (PET) fabrics were coated with the coupling agent 3-glycidyloxypropyltrimethoxysilane and graphene oxide (GO) by conventional pad-dry-cure processing method. The coated PET fabrics burnt without the melting state and formed the denser and tighter char directly during the combustion. In order to explain the restraining effect of GO, the structure and thermal stability of the coated PET fabrics, the structure of the forming char after vertical burning test were discussed. The morphology images showed that GO formed the uniform film on the entire fabric surface and infrared spectra indicated the successful fabrication of GO on PET fabric by the presence of the peaks at 3420 cm-1 and 1732 cm-1. While the thermal stability changed slightly with coating and XPS analysis illustrated that the ratio of C/O decreased and the function group C = O increased. It can be shown that the addition of GO played the physical role in the dripping resistance of coated PET fabrics.

The structure and property of Abelmoschus manihot Manihot fibers were investigated in the present work. Its transverse section was irregular polygon and the single fiber was cylindrical shape. It belonged to cellulose I crystalline structure and its crystallinity was near to cotton and ramie. The breaking strength was lower than ramie fibers and the elongation at break was approximate with these fibers. The moisture regain was better than cotton. It can be dyed easily using high-temperature reactive red dyes and blue dyes. Also, it had the higher thermal stability than cotton.
