An x-ray detectable fabric comprising: a first set of fibers having a rayon composition; a second set of fibers having a polymeric composition with an x-ray detectable material impregnated therein; wherein the first and second sets of fibers are in an entangled state as a cohesive porous fabric, and wherein fibers in the second set of fibers are distributed throughout the fabric. In particular embodiments, the first and second sets of fibers are in a non-woven state, with a bonding agent maintaining adhesion between the fibers. The polymeric composition in the second set of fibers may be selected from, for example, vinyl addition polymers, polyesters, rayon, nylon, and cellulosic compositions. The first set of fibers may or may not also include an x-ray detectable material.

A non-painted thermoplastic resin composition including viscose rayon so as to embody a marble pattern and a method for making it are disclosed. The viscose rayon is included in the thermoplastic resin composition to minimize the deterioration of physical properties while minimizing weld lines and flow marks during an extrusion process, and a luxurious outer appearance of a marble pattern is embodied without additional post-processing or painting process. The non-painted thermoplastic resin composition includes 80-90 parts by weight of a thermoplastic resin composition, 0.1-5 parts by weight of a carbon fiber, and 0.1-3 parts by weight of viscose rayon based on 100 parts by weight of the entire resin composition. The viscose rayon provides an effect of minimizing weld lines and flow marks during injection, improving physical properties, and providing the luxurious appearance of the marble pattern.
