Nyob rau hauv chav tsev kub
1. Dye Lub luag hauj lwm ntawm dye cawv muaj pes tsawg leeg additives
1) Muaj pes tsawg leeg: glacial acetic acid, leveling agent SE (los yog dispersant N), disperse dye
2) Lub luag hauj lwm ntawm additives: ① Glacial acid: glacial acetic acid, leveling tus neeg saib xyuas SE (los yog dispersant N), disperse dye ② Dispersant N (levelling agent SE) Disperse cov disperse dyes tusyees nyob rau hauv lub dye cawv, tuav lub stability ntawm cov xim. nyob rau hauv dye cawv, thiab tiv thaiv cov dye los ntawm agglomerating. 2. Vim li cas thiaj yuav tsum dyes disperse dyed nyob rau hauv me ntsis acidic tej yam kev mob (PH=5-6)?
① Yog tias tus nqi PH tsawg dhau (PH—< 4="→" dye="" xim="lub" teeb="" yuav="" hloov,="" thiab="" cov="" xim="" ntawm="" cov="" xim="" yuav="" txo="" qis.="" decomposed="" thiab="" rhuav="" tshem="" nyob="" rau="" hauv="" kub="" thiab="" alkaline="" tej="" yam="" kev="" mob,="" cov="" xim="" yuav="" tsaus,="" thiab="" polyester="" yuav="" puas="" nyob="" rau="" hauv="" alkaline="" kub="" tej="" yam="" kev="">
3. Yuav ua li cas ntxiv cov ntaub ntawv rau disperse dyeing? 1) Cov txheej txheem tshuaj: dej txias ntaus: dej sov (< 50="" ℃="do" tusyees,="" dilute="" thiab="" lim="" ua="" ntej="" muab="" tso="" rau="" hauv="" dyeing="" vat="" rau="" siv.="" ①="" ua="" ntej="" ntxiv="" glacial="" acid="" (ntxiv="" tom="" qab="" dilution)="" los="" kho="" ph="" tus="" nqi="" (tseem="" ntsuas="" nrog="" ph="" daim="" ntawv="" xeem)="" ②="" ntxiv="" cov="" tshuaj="" yaj="" yeeb="" yaj="" kiab="" thiab="" cov="" dispersant.="" ntawm="" lub="" thoob="" pub="" mis="" tsis="" zoo="" ua="" ntej="" pub="">
4. Vim li cas qhov kub dyeing siab tshaj 130 ℃? Vim tias qhov feem pua dyeing ntawm disperse dyes yog qhov siab tshaj ntawm 130 ° C, cov xim yog ci, qib dyeing, thiab tsis tshua muaj ntab. 1) Yog tias qhov kub thiab txias dhau lawm, cov zas xim yog yooj yim rau decompose thiab fiber ntau yooj yim puas. 2) Yog tias qhov kub thiab txias dhau lawm, cov tshuaj zas xim yuav qis thiab cov xim nkag mus rau cov xim yuav tsis zoo, yog li qhov kub siab tshaj plaws rau cov dyes disperse yog 130 ° C.
5. Nce thaum dyeing: Dab tsi yog qhov yuav tsum tau ua kom txias thiab yog vim li cas? 1) Cov kev xav tau cua sov: Tswj qhov kub thiab txias, txwv tsis pub qhov kub thiab txias tuaj yeem ceev ceev, nws yuav ua rau cov xim dyed sai heev, thiab qhov tshwm sim ntawm cov xim sib txawv yuav tshwm sim. ① Xim paj: hais txog qhov tsis sib xws dyeing. ② Kev txuag hluav taws xob nruab nrab (90 ℃ * 5') Lub hom phiaj: kom sov cov xim tom qab sib npaug ntawm cov fiber ntau los tiv thaiv stains. ③ Cua kub ceev: yuav tsum qeeb, feem ntau tswj ntawm 1 ~ 2 ℃ / min 2) Cov cua txias yuav tsum:① Yuav tsum tau: Tom qab dyeing, qhov kub yuav poob qis dua 80 ℃ (feem ntau tswj ntawm 1 ~ 2 ℃ / min) ② Yog tias qhov kub thiab txias poob sai sai tom qab dyeing, nqaij qaib ko taw prints (wrinkles) yuav tshwm sim los yog cov ntaub xav tias ntxhib. ③ Kev ua haujlwm dav dav: Tom qab txias rau 80 ° C ntawm 2 ° C / min, ua kev kho tom qab ntxuav. Nws yog txwv tsis pub qhib lub hau thiab ntxuav nrog dej siab tshaj 80 ° C, txwv tsis pub muaj teeb meem kev nyab xeeb yooj yim tuaj yeem tshwm sim.
6. Lub hom phiaj ntawm 130 ℃ kub preservation (30 ~ 45min) yog dab tsi? 1) Lub Hom Phiaj: Txhawm rau zas cov fiber ntau kom huv thiab sib npaug. Lub teeb xim: luv luv tshav kub preservation lub sij hawm. Tsaus xim: Lub sijhawm txuag hluav taws xob ntev. 2) Yog tias lub sijhawm tuav lub sijhawm luv dua → nws tsis haum rau qhov sib txawv ntawm cov xim, thiab nws yooj yim ua rau xim plooj thiab lub teeb xim. Cov ntsiab lus ua haujlwm dyeing 1. Ua tib zoo saib xyuas kev huv ntawm lub tank kub siab conveying pipeline thaum dyeing thiab ntxuav lub tank. 2. Npaj cov ntaub ntawv thiab xim ua ntej, feem ntau 20-30 feeb ua ntej, do thiab disperse lawv tusyees rau tom qab siv. 3. Qhov kub ntawm cov khoom siv tshuaj yuav tsum tsis txhob siab tshaj 50 ° C, txwv tsis pub cov xim yuav agglomerate. 4. Txheeb xyuas seb lub vijtsam lim ntawm lub tank tshuaj puas zoo ua ntej qhib cov khoom siv. 5. Nws yog txwv tsis pub ntxiv dyes thaum cua sov. Tom qab ntxiv dyes, cov ntaub yuav tsum tau rhuab rau ib lub sij hawm ntawm lub sij hawm (xws li 5min). 6. Cov cua sov thiab cua txias yuav tsum nruj me ntsis raws li cov txheej txheem nkhaus kom tsis txhob muaj cua sov thiab txias ntau dhau los ua rau muaj teeb meem zoo. 7. Tom qab dyeing, qhov kub thiab txias yuav tsum tau txias kom qis dua 80 ℃ ua ntej qhib lub qhov rooj ua haujlwm ntawm dyeing vat kom tsis txhob kub hnyiab.
