Cov xim ntawm txoj phuam qhwv caj dab yog ci ntsa iab
Muab cov phuam khaus ntawm cov xim dawb, dawb xim dawb thiab luam ntawv ua tiav cov khoom ua ntej, kev tsim cov xim, cov duab xim, luam yeeb yaj duab thiab cov khoom siv luam yeeb, luam ntawv thiab luam ntawv thoob plaws hauv txoj haujlwm.
Sau cov phuam kauv caj dab muaj xim zoo nkauj thiab dawb xim dawb thiab luam ntawv ua tiav cov khoom muag zoo nrog kev zoo los sis qhov phem. Yaug ib yam khoom tiav yaug tsis yog tuaj yeem cuam tshuam rau cov ntawv luam ntawm cov permeability, uniformity, thiab yuav muab cov ntaub rau cov xim, xim kaj, dawb xim dawb muaj feem xyuam.
Rau qhov kawg no, txhawm rau txhim kho cov xim ntawm cov ntawv luam thiab xim dawb, thawj yog ua ib txoj haujlwm zoo ntawm cov ntaub luam ntawv yaug cov khoom siv yig.
Ntshiab paj rwb luam ntawv ua tiav ib qho khoom tiav raws li ib qho piv txwv tias yuav tsum tau hu nkauj, yuav tsum ncav cuag 3-4; desizing mus rau net, desizing tus nqi yuav tsum siab; txhuam los ntawm cov tshuaj dawb, dawb dawb los ntawm 80% los yog ntau dua, ua ntej lub hau plaub hau 10cm / 30min; mercerization alkalinity 240-280g / L, barium tus nqi ntawm 135 los yog ntau tshaj, kom nruj tswj hwm lub mercerization tom qab alkali, tag nrho pickling, daim ntaub pH kom muaj 7-8. Lwm cov qauv yog polyester / paj rwb yog tsim ntawm polyester thiab paj rwb ob yam khoom sib txawv ntawm cov fiber ntau.
Cov ntsiab lus tsim nyog, polyester fiber synthetic pretreatment yuav tsum tshaj cov paj rwb fiber ntau tsawg, tab sis npuag ntau txheej txheem siv hauv polyester yog 4-5 hom kev sib xyaw siv, qhov sib txawv ntawm qhov loj dua whiteness;
Cov paj rwb yuav tsum tau tshem tawm cov ntawv xov xwm ntuj thiab neeg tsim ua los ntawm kev kho mob ua ntej. Nyob rau hauv cov paj rwb ntaub ntau lawm, cov paj rwb yog tov nrog ntau hom qib.
Lub xauv npoo ntawm cov ntaub npog yog tsawg thiab tsis hnav. Yog li, cov ntaub ntawm cov kev kho mob ua ntej yuav tsum muaj zog, qee cov neeg ntawm cov polyester / paj rwb ua ntej kev kho ua ib sim comparative, kev siv sub-bleaching txheej txheem, cov pa oxygen bleaching txheej txheem thiab alkali-oxygen bleaching txheej txheem thiab alkali cov txheej txheem tshuaj dawb tau txais lub hauv paus ntawm cov ntsiab lus ntawm 85% -87%, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem sub-bleaching yog qhov siab tshaj plaws, tab sis cov txheej txheem tsis yog kev ntxuav cov txheej txheem, yog li tam sim no tsis tau siv.
Tam sim no, ntau cov txheej txheem muaj oxygen-oxygen bleaching txheej txheem, alkali-oxygen bleaching txheej txheem thiab lwm yam dab ntxiv kom tau ib tus zoo whiteness nqi.
