A PROCESS OF DYEING ON POLYPROPYLENE FIBER BY USING BASIC DYE AND THE POLYPROPYLENE FIBER DYED THEREOF

摘要

The present invention, irradiation of electron beam, gamma ray, plasma in air in a polypropylene fiber, and combined with the basic dye to process the chemicals herein relates to a polypropylene fiber to be dyed from the dyeing method and which the polypropylene fibers with the basic dye after the functional group that is, introducing a dyeing seat to the functional groups and and simultaneously dyeing of a uniform quality product by staining by the basic dye to the ionic bonding to extend the functionality of the polypropylene fiber to be used as a fiber for clothing to help you get.; To this end, the present invention includes the steps of introducing the primary active species of epoxy groups in the polypropylene fiber by reaction with oxygen in the air as the irradiating radiation onto a polypropylene fiber in the air; The epoxy group of chlorosulfonic acid, 3- (chlorosulfonyl) benzoic acid or 4- (chlorosulfonyl) benzoic acid, is reacted in one or phosphoric acid sulfone group, a carboxyl group which is dissociated into anion on each of the polypropylene fibers, dyeing, such as a phosphate group introducing a seat; And by an ionic bond with the basic dye to the dyeing seat and the cationic it is characterized in that consisting of the step of dyeing the polypropylene fibers.
