NOVELTY - Preparing electric control releasing negative oxygen ion cotton fabric comprises (i) soaking normal cotton fabric in ethanol solution and completely wet absorbing, taking out cotton fabric for deionized water times of washing, and airing; (ii) adding ammonium persulfate to hydrochloric acid solution, dissolving, obtaining hydrochloric acid solution of ammonium persulfate; (iii) adding aniline into hydrochloric acid solution, obtaining hydrochloric acid solution of aniline, placing cotton fabric to soaking and completely wet absorbing; (iv) adding hydrochloric acid solution of ammonium persulfate to material system, reacting and taking out cotton fabric, washing and airing; (v) dispersing europium oxide to oxide dispersion graphene and stirring to obtain suspension, adding aqueous polyurethane to obtain composite finishing liquid; and (vi) soaking cotton fabric to composite finishing liquid by dipping, taking out cotton fabric and drying. USE - The method is useful for preparing electric control releasing negative oxygen ion cotton fabric. ADVANTAGE - The method: introduces rare earth oxide/graphene, thus cotton fabric has electronegative oxygen ion releasing function, and lays a foundation for the development of the functional cotton fabric material for electrotherapy massage supplies.
