Koj paub ntau npaum li cas txog cov ntaub ntawv fiber ntau uas hloov xim?
(1) Photosensitive xim-hloov cov ntaub ntawv
Photosensitive xim-hloov cov ntaub ntawv yog ib tug functional dye uas yuav hloov xim nyob rau hauv lub irradiation ntawm ultraviolet lub teeb los yog pom lub teeb, thiab yuav rov qab mus rau lub qub xim tom qab lub teeb ploj. Cov ntaub ntawv hloov xim hloov xim feem ntau muaj xws li nyiaj chloride, nyiaj bromide, stilbenes, spirocycles, norbornadiene, fulgid anhydride, triphenylmethane derivatives, salicylic aniline compounds, thiab lwm yam. Tam sim no, cov ntaub ntawv hloov xim photosensitive tau tsim muaj plaub xim xim: ntshav, daj, xiav, thiab liab. Cov txheej txheem pib ntawm plaub qhov sib txawv ntawm cov khoom siv optically yog tag nrho cov voj voog kaw, uas yog, tsis muaj xim thaum luam tawm ntawm cov ntaub, thiab lawv tig xim liab, daj, xiav, thiab liab thaum raug ultraviolet lub teeb.
(2) Thaum tshav kub kub-sensitive xim-hloov khoom
Yog vim li cas vim li cas cov khoom siv hluav taws xob hloov xim tuaj yeem hloov xim yog tias lub cev hloov xim tuaj yeem ua rau muaj kev hloov hauv cov qauv sab hauv, uas ua rau muaj kev hloov xim. Thaum kub poob, cov xim rov qab. Piv nrog rau photosensitive dyes, muaj ntau ntau kev tshawb fawb ntawm thermosensitive dyes nyob rau hauv tsev thiab txawv teb chaws, tshwj xeeb tshaj yog nyob rau hauv lub nam ntawm textile printing, uas tau tiav tej yam tshwm sim, thiab ib tug series ntawm thermosensitive printing khoom tau tawm los.
Piv txwv li, RT series tsim nyob rau hauv peb lub teb chaws yog kub-rhiab discoloration khoom. Thaum hnav cov txheej txheem, cov ntaub ntawv qhia cov xim hloov tau nrog lub caij sib txawv, thaj chaw, thiab qhov kub thiab txias sab hauv tsev thiab sab nraum zoov. Tam sim no, lub teb chaws tseem ceeb uas tuaj yeem tsim cov xim hloov xim thiab paub txog kev siv tshuab yog Britain, Nyiv, thiab Taiwan.
(3) Moisture-rhiab xim-hloov cov ntaub ntawv
Lub ntsiab yog vim li cas rau cov discoloration ntawm cov av noo-rhiab xim-hloov cov ntaub ntawv yog cov av noo nyob rau hauv cov huab cua ua rau lub structural hloov ntawm cov xim nws tus kheej, yog li hloov lub haum spectrum ntawm lub hnub ci pom, thiab ambient humidity muaj ib co catalytic. cuam tshuam rau lub discoloration ntawm lub cev hloov xim. Lub ntsiab tseem ceeb ntawm cov dej-rhiab xim-hloov xim-hloov xim-hloov luam ntawv paste yog xim-hloov cobalt ob chav ntsev, thiab lub cev hloov xim yog ruaj khov rau cov ntaub los ntawm cov nplaum thaum thov. Txhawm rau ua kom cov xim tsis muaj xim, yuav tsum tau ntxiv ib qho sensitizer los pab lub cev discoloration ua tiav cov txheej txheem no, thiab qee cov xim ntxiv kuj ntxiv los txhim kho qhov vividness ntawm cov ntaub discoloration.
Yog tias cov xim hloov xim yog cov xim sib xyaw ua ke hauv cov xim luam ntawv, nws tuaj yeem siv rau hauv cov phuam da dej, phuam da dej, phuam so tes, khaub ncaws ua luam dej, khaub ncaws puam, thiab lwm yam, kom tau txais cov qauv luam ntawv tshwj xeeb. Nws yog dawb thaum qhuav, thiab ua translucent thaum ntub thiab cov qauv ploj.
Kev tsim technology ntawm cov ntaub ntawv hloov xim
Nyob rau hauv lub tshav pob ntawm textiles, kev tsim technology ntawm cov xim-hloov cov ntaub ntawv mas muaj xws li ob yam: hloov xim fibers thiab xim-hloov dyes:
Cov xim hloov xim siv rau hauv textiles feem ntau yog thermochromic dyes, photochromic dyes thiab noo noo-rhiab xim-hloov dyes. Txawm li cas los xij, vim tias qhov tsis txaus ntseeg ntawm qhov nrawm nrawm thiab ntxuav nrawm ntawm cov dyes, xyoo 1990, tib neeg tau qhia txog microcapsule thev naus laus zis rau hauv kev npaj cov xim hloov xim, uas ua rau daim ntawv thov hloov xim dyes hauv textiles tau txais txiaj ntsig zoo. Piv nrog rau kev luam ntawv thiab dyeing tshuab, xim-hloov fiber ntau tshuab muaj qhov zoo tshaj plaws: cov ntaub uas tsim tau muaj tes zoo, zoo ntxuav tsis kam, thiab cov xim hloov tau ntev.
Txoj kev loj hlob ntawm cov ntaub ntawv hloov xim
Cov khoom siv fiber ntau hloov xim yog cov khoom siv hluav taws xob ua haujlwm siab uas tau tsim kho sai nyob rau xyoo tas los no thiab muaj qhov tseem ceeb. Nws muaj txiaj ntsig ntxiv thiab muaj txiaj ntsig zoo. Nrog rau tib neeg kev nce qib siab thiab cov kev cai ntawm tus kheej rau cov khaub ncaws thiab cov kev xav tau siab dua rau kev ua haujlwm tiav fabrics, kev txhim kho cov ntaub ntawv hloov xim tshiab thiab cov xim hloov xim yuav muaj kev txhim kho zoo thiab qhov chaw siv dav.
