APPLICATIONS OF NUCLEAR RADIATION AND RADIOISOTOPES TO TEXTILE MATERIALS AND PROCESSES. Annual Report for the Period November 1, 1958 to November 1, 1959
ABS>Research on modification of textile fibers by naked exposure to radiation is described along with fiber modification by in situ polymerization and/or graft polymerization of vinyl monomers. In preliminary work, the rate at which a number of textiles were changed by gamma radiation was determined. Data on gamma radiation effects are included for rayon, acetate, Dacron, nylon 66, Orlon, Polypropylene, wool and silk. The behavior of several monomers during gamma irradiation was also investigated. Acrylonitrile was selected for experiments to establish principles or techniques for application of vinyl compounds to fibers. Data are given on addition of acrylonitrile to cotton under various conditions, as well as on the addition to other fibers under irradiation conditions and as a function on time. In research on beta gage applications, fabric uniformity studies were conducted on various cotton fabrics and data on fiber weight determined non-destructively are given. In research on activation analysis the general prob lem of fiber and yarn identification was investigated with tae purpose of establishing characteristic gamma energy spectra for various fibers. By use of such data it is possible to differentiate fibers from one another and also fibers similar in composition but manufactured at different plants by the same producer, and fibers similar in composition produced by different manufacturers. Samples were irradiated by thermal neutrons at 2 x 10/ sup 8/ neutrons/cm/sup 2//sec. The resulting spectra are discussed and it is noted that the present data indicate that the techniques may be useful; however, new lots of fiber should be examined to confirm current findings.
