Studies of possible applications of nuclear radiation and radioisotopes to textile materials and processes were undertaken. A broad study was made covering the modification of fibers by exposure to radiation, the modification of fibers by in situ polymerization and/or graft polymerization of vinyl monomers, the application of beta gauges to textile processes, and the use of tracer and activation analysis techniques. Various vinyl monomers were added to textile yarns by gamma radiation using a vapor phase technique. The vapor phase technique was useful only for the volatile monomers acrylonitrile and vinyl acetate at 70°F and one atmosphere pressure. Acrylonitrile and vinyl acetate were readily added to cotton, rayon, acetate, polypropylene, and nylon. Small amounts were added to polyesters and none to acrylics. Activation analysis was proposed for fiber identification and process studies. For fiber identification gamma-ray spectra were presented for most of the commercial textile fibers. A preliminary study was made of fiber blending in the cotton spinning process using activation analysis with manganese as the tracer.
