Fluorescent pa'epa'e sui o se ituaiga o fa'alapotopotoga fa'aola e mafai ona fa'aleleia le pa'epa'e o ie alava ma pepa, e ta'ua fo'i o le sui fa'amasani fa'ama'i ma le sui fa'amalama fa'amalama.O ie, ma isi, e masani ona samasama ona o le aofia ai o mea leaga lanu, ma sa faʻaaogaina vailaʻau vailaʻau e faʻamalo ai i latou i aso ua mavae.O le auala o le faʻaopoopoina o se sui paʻepaʻe i le oloa ua faʻaaogaina nei, ma o lana galuega o le faʻaliliuina lea o le ultraviolet le vaaia o loʻo faʻaaogaina e le oloa i le lanumoana-violet fluorescent radiation, lea e fetaui ma le uluai lanu samasama moli ma avea ma malamalama paʻepaʻe, lea. fa'aleleia atili le gafatia o le oloa e tatalia le la.o le pa'epa'e.Brighteners ua faʻaaogaina lautele i ie, pepa, fufulu paʻu, fasimoli, paʻu, palasitika, pigments ma vali.
Brighteners o loʻo i ai uma faiga faʻapipiʻi faʻataʻamilomilo i le faʻasologa o vailaʻau, e pei o: stilbene derivatives, phenylpyrazoline derivatives, benzothiazole derivatives, benzimidazole derivatives, coumarin derivatives ma Naphthalimide derivatives, ma isi, e aofia ai stilbene derivatives e maua ai le tele o fua.Fa'aaogā metotia ma meatotino e vaevae ai fa'amalama e mafai ona vaevaeina i ni fa'ailoga e fa:
O se fa'asologa o lo'o fa'asino i vaila'au pa'epa'e fela'ua'i e mafai ona fa'atupu cation i se vaifofo vai.E fetaui mo le faʻamaʻaina o alava acrylic.B fa'asologa fa'amalamalama mata e talafeagai mo le fa'amalamalamaina o alava cellulose.C fa'asologa o lo'o fa'atatau i se ituaiga o mea fa'amasani fa'amalama fa'asalalauina i le vai ta'ele i luma o le fa'asalalauina, e talafeagai mo le fa'amaina o le polyester ma isi filo hydrophobic.D fa'asologa e faasino i le fluorescent pa'epa'e sui talafeagai mo alava porotini ma nailon.E tusa ai ma le fausaga o vailaʻau, e mafai ona vaevaeina le paʻepaʻe i ni vaega se lima: ① ituaiga stilbene, faʻaaogaina i le alava cotton ma nisi alava faʻapipiʻi, fai pepa, fasimoli ma isi pisinisi, faʻatasi ai ma fluorescence lanumoana;② ituaiga coumarin, ma le manogi O le fausaga faavae o pi ketone, faʻaaogaina i polyvinyl chloride plastics, ma isi, e malosi le fluorescence lanumoana;③ ituaiga pyrazoline, faʻaaogaina mo fulufulu mamoe, polyamide, alava acrylic ma isi filo, ma fluorescence lanu meamata;④ ituaiga benzoxazine, faatasi ai mo alava acrylic ma isi palasitika e pei o le polyvinyl chloride ma polystyrene, ei ai fluorescence mumu;⑤phthalimide ituaiga, mo polyester, acrylic, nylon ma isi filo, ma fluorescence lanumoana.O loʻo i luga o le faʻavasegaina o mea paʻepaʻe.Pe a filifilia e le au faʻatau mea faʻamaʻi paʻepaʻe, e tatau ona latou malamalama muamua ia latou lava oloa, ina ia mafai ai ona latou filifilia le sui faʻamaʻi saʻo.Ma e tatau foi i tagata faatau ona iloa pe a faʻaaogaina vailaʻau paʻepaʻe, o vailaʻau paʻepaʻe e naʻo le faʻamalamalamaina ma le felagolagomai lanu, ma e le mafai ona suia le vailaʻau vailaʻau.O le mea lea, o le mea lanu e togafitia saʻo ma se mea faʻamaʻi paʻepaʻe e aunoa ma le faʻafefeteina, ma e le mafai ona maua faʻavae le aafiaga paʻepaʻe.Ma o le sui pa'epa'e e le sili atu le pa'epa'e, ae o lo'o i ai se fa'atonuga saturation.Ova atu i se tau fa'atapula'a mautu, e le gata e leai se aafiaga whitening, ae faapena foi samasama.
