Cov yam ntxwv ua tau zoo

Cov fluorescence Qaib tau tawm los yog siab, thiab cov tshuaj tsuas yog ib feem peb ntawm cov stilbene-triazine hom fluorescence tus neeg sawv cev. HEE purple (xiav kev tawm tsam lub teeb), tsis tshua muaj zog rau chlorine tshuaj dawb thiab muaj zog ua kom dawb huv cov hmoov av thiab xab npum thiab xab npum, txhim kho nws cov tsos zoo. Zoo kev mus ncig, ntawm qhov kub tsawg, da dej me dua li txhais tes ntxuav thiab tshuab ntxhua khaub ncaws huv si ntawm cov khaub ncaws, yuav tsis tsim cov pob. Cov hmoov dawb dawb, hauv dej txias thiab dej sov ntawm cellulose fiber. Polyamide. Protein proty. Paj rwb thiab lwm yam fluorescent whiting tau muaj cov txiaj ntsig zoo dua, thaum muaj lwm cov tshuaj ntxuav hniav fluorescent tsis zoo ntawm qhov kub tsis zoo. Txoj kev ntxuav hniav dawb ceev ceev yog nrawm, thiab cov ntaub yuav ncav cuag qhov siab zoo nyob rau lub sijhawm luv luv. Nws muaj lub hnub so qhuav thiab ntub dej nrawm nrawm thiab ntxim nyiam cov fluorescent thaum lub ntsej muag kom huv si, thiab ua rau cov ntaub ua kom zoo nkauj hauv qab kev ua ntawm cov hws khov. Tom qab rov ntxuav dua, cov nyhuv yog qhov zoo dua, cov tshuaj ntxuav cov fluorescent, thiab cov ntaub qhwv zoo nkauj dua, cov ntaub qhwv ntsej muag yuav ua rau cov ntaub ntsuab tom qab siv tas. Tsaus nti, dawb txo. Insoluble hauv chlorinated hydrocarbons, tab sis tuaj yeem raug tawg hauv lawv. Cov khoom lag luam ntawm cov khoom no muaj qhov nruab nrab loj me me, uas yog cov khoom ib puag ncig.

Kev siv

Mas siv nyob rau hauv high-qib hluavtaws ntxhua hmoov. Super concentrated kua xab npum, kuj tseem siv tau hauv xab npum. Lub ntsej muag ntxuav hniav ntawm xab npum kuj tseem siv tau rau hauv cov ntaub mos muag muag thiab tus neeg sawv cev ua tiav. Nws tuaj yeem siv nyob ib leeg lossis ua ke nrog lwm cov tshuaj fluorescent whitening raws li cov kev xav tau txawv. Paj rwb yog dyed los ntawm kev qaug zog thiab ntaub qhwv, ntaub plaub yog dyed los ntawm kev qaug, thiab nylon yog dyed los ntawm kev qaug zog. Nqaij Dyeing txoj kev kub teeb tsa. Acid ncoo zas xim lossis kuab ntaub ntawv dyeing txoj kev, kuj tseem tuaj yeem zas ntaub so, kev ceev ceev. Lub estinity rau paj rwb yog tsawg rau nruab nrab, thiab kev sib txawv rau cov plaub tsiaj, lo lo ntxhuav thiab nylon yog siab.
