Abstract
Paramagnetic susceptibility has been imparted to raw unprocessed cotton fibers by impregnating the fibers with a paramagnetic organometallic rare earth compound dissolved in hydrocarbon solvent. The strength of the imparted property is sufficient to allow for the manipulation of the textile fibers by magnetic force fields in conjunction with radically new techniques of textile processing. The paramagnetic susceptibility is removable and whatever paramagnetic compound use is recoverable.
Claims7
A method of imparting paramagnetic susceptibility to raw unprocessed cotton fibers to provide a means of manipulating said fibers in a magnetic force field, the method consisting essentially of:
- a. impregnating cotton fibers with a solution consisting of about from 1% to 10% by weight of a paramagnetic organometallic rare earth compound selected from the group consisting of dysprosium acetylacetonate and holmium acetylacetonate dissolved in an organic solvent selected from the group consisting of benzene, chloroform, ethyl ether, and hexane;
- and
- b. drying the wet impregnated cotton fibers to obtain fibers with a paramagnetic susceptibility of about from 10.sup.-6 to 10.sup.-5 electromagnetic units per gram (emu/gm) which is sufficient to render the fibers reactive to magnetic forces.
