Description

A kind of fluorescence remover and the method with fluorescence on its removal textile
Technical field
The invention belongs to textile fluorescence to remove field.
Background technology
Through research, fluorescer improper use has greatly harm, and chemical composition is easily decomposed like that unlike, and It is to be accumulated in human body, generates many harmful substances, cut down body immunity significantly.Fluorescer and the protein knot outside wound It closes, can also hinder the healing of wound, human body cell is made variation sexual orientation occur, cumulative toxicity is in liver or other important devices Official can become potential carcinogenic factor.If clothes does not clean up, remaining fluorescent component is also left, body one is sweat, Remaining fluorescer on clothes can be dissolved, and make skin contact to fluorescent material, skin surface contains protein at this time Cutin will generate stimulation combined with fluorescer to skin, trigger allergy and itch, increase the morbidity chance of allergic dermatitis.Cause This, in textile fabrics, due to being mixed into fluorescent material in raw material or work in-process attaches fluorescent whitening agent or improper addition is glimmering Optical brightener and with fluorescence or due to application scenario limitation there are fluorescent materials（The articles for babies of such as some countries）, It is frequently necessary to be removed.The report of the method eliminated at present to fluorescent material is more common in paper recovery processing, on textile The removing method of fluorescent whitening agent there is no open report.
Conventional fluorescence elimination method has two classes, and one kind is that the chemistry for using oxidizer treatment to destroy fluorescent whitening agent is tied Structure is common to have oxidizer containing chlorine such as sodium hypochlorite, chlorine dioxide so as to eliminate fluorescence, and also useful oxygen containing oxidant is as crossed vinegar Acid treatment.If Chinese patent CN102230291A discloses a kind of method for eliminating fluorescent material in secondary stock, using titanium dioxide Fluorescence Quenching Agent of the chlorine as secondary stock, the bleaching of paper pulp and removal fluorescence are carried out at the same time, because fluorescent material chlorine resistance is very poor, Chlorine and hypochlorite can destroy most of fluorescence structures, make its unstressed configuration property, but environmental legislation limits chlorine and hypochlorous acid The use of salt.Another kind of is to add fluorescence control agent to eliminate fluorescence, and fluorescence control agent is typical polyamides quaternary ammonium compounds Structure.Fluorescent whitening agent is anionic property mostly in itself, and fluorescent whitening agent has highly stable chemical constitution.Therefore, may be used Using fluorescence control agent per se with cationic come the anion of fluorescent whitening agent in effectively neutralized system, make color development Active anion group is denatured, and achievees the purpose that effectively eliminate fluorescence in system.As Chinese patent CN103614943A is disclosed A kind of method of fluorescent brightener levels in reduction paper manufacturing systems, using cationic polyacrylamide, polyamine, diethylenetriamine five Methene phosphoric acid is with 1:5:2 scalemic thereof reduces fluorescent whitening agent keeping on page, so as to drop as Fluorescence Quenching Agent The fluorescence content of low page.It cannot destroy the molecule for removing and fluorescing, but can inhibit the property that they fluoresce, and mask glimmering Light characteristic does not destroy the molecular structure and chromophoric group of fluorescent material.Once polyamides quaternary ammonium compounds is hydrolyzed, then fluorescence Brightening agent has recovered its fluorescence again.The Fluorescence Quenching Agent of above-mentioned Strong oxdiative type eliminates the whiteness decline of paper pulp after fluorescence, leads The increased whiteness of blanching effect institute before cause is almost cancelled, and is not only caused the waste of chemicals, but also is also added Flow expends a lot of resources more, increases the burden of environment.And polyamides quaternary ammonium fluorescence control agent has certain work to inhibiting fluorescence With, but for the stronger system of fluorescence, removal effect is limited.
