Hais "tsis yog" rau cov dej paug hauv kev lag luam textile
Rau cov cheeb tsam uas muaj kev lag luam textile raws li kev lag luam tseem ceeb, dej paug yog ib qho teeb meem uas yuav tsum tau daws.
"Kev lag luam textile ib txwm muaj yog ib qho kev lag luam uas muaj kev siv hluav taws xob siab, kev siv dej siab thiab muaj kuab paug siab, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntawm textile dyeing thiab xov, uas yuav tsim cov dej khib nyiab ntau thiab cov khoom pov tseg. dyes, sizing agents, auxiliaries, oiling agents, fiber impurities and inorganic salts, with high content of organic pollutants, high alkalinity, loj hloov nyob rau hauv dej zoo thiab siab chromaticity, uas ua rau nws nyuaj los daws cov pa phem. dej paug tshwm sim los ntawm textile printing thiab dyeing, peb yuav tsum tsis tsuas yog muaj cov koom haum saib xyuas nruj me ntsis tswj cov kav dej phwj tuaj, tab sis kuj cia siab rau kev kho dua tshiab ntawm kev luam ntawv thiab dyeing technology.
"Kev tshawb fawb thiab kev loj hlob ntawm anhydrous dyeing thev naus laus zis yog txhawm rau txo cov khoom luam tawm thiab dyeing dej khib nyiab los ntawm qhov chaw." Tam sim no, lub hauv paus ntawm anhydrous dyeing thev naus laus zis tsim nyob rau hauv Suav teb yog siv cov nruab nrab tsis muaj dej rau dyeing. "Piv txwv li, supercritical carbon dioxide dyeing thev naus laus zis tuaj yeem ua kom cov pa roj carbon dioxide liquefy carbon dioxide rau hauv cov kua nruab nrab los ntawm kev nias, thiab tom qab ntawd txo qhov siab tom qab dyeing hauv lub xeev no. Cov pa roj carbon dioxide tuaj yeem rov qab tau yam tsis muaj dej ntxhua hauv tag nrho cov txheej txheem, thiab tsis muaj dej khib nyiab yuav raug. Lwm qhov yog siv cov kuab tshuaj organic hloov dej ua qhov nruab nrab rau dyeing. Tom qab dyeing, cov organic hnyav kuj tuaj yeem siv dua. "
Cov txheej txheem anhydrous dyeing no tau siv rau hauv kev tsim khoom. Qee lub tuam txhab tau tsim cov thev naus laus zis ua tiav ntawm supercritical carbon dioxide dyeing thiab tsim ib txoj kab ua qauv qhia rau kev lag luam ntawm supercritical carbon dioxide anhydrous dyeing, txo cov dyeing efficiency ntawm textiles los ntawm 8 mus rau 12 teev ntawm cov tsoos dej dyeing rau 3 mus rau 4 teev. Lwm lub tuam txhab siv cov organic hnyav dyeing tshuab. Hauv cov txheej txheem dyeing, 100 feem pua ntawm cov dej tau txais kev cawmdim, 39.3 feem pua ntawm kev siv hluav taws xob raug txo, qhov kev kho cov xim yog ntau dua 97 feem pua, thiab cov kuab tshuaj rov qab yog ntau dua 99 feem pua.
Tsis tsuas yog cov txheej txheem "dyeing" txuag dej, tab sis cov txheej txheem ntxuav tom qab dyeing kuj tau hloov pauv vim qhov tshwm sim ntawm cov thev naus laus zis tshiab.
Ua cov hwj qub thiab cov khaub ncaws zoo nkauj
Lub raj mis yas pov tseg tuaj yeem ua dab tsi? Yog tias muab pov tseg tsis tu ncua, nws yog cov khib nyiab uas ua rau ib puag ncig; Tab sis yog tias nws tau rov ua dua tshiab, nws yuav dhau los ua ib qho hnav ris tsho, khoom ua si plush, lossis ib txheej ntawm lub tsheb sab hauv.
