Thaum cov kua qaub dyed dyes, cov teeb meem tseem ceeb yog: stigma, discoloration, yellowish ntxoov, tsis txaus leveling zog, thiab lwm yam. Yog vim li cas rau cov teeb meem no, ntxiv rau qhov tsis zoo ntawm cov dye, yog hais tias tus txheej txheem yog tsis ua hauj lwm los yog cov ntsiab lus. tsis kam nrog kom raug, nws kuj yog qhov ua rau. Kab lus no tsuas yog siv cov dyeing nylon nrog acid dyes ua piv txwv los tham txog cov txheej txheem dyeing ntawm cov kua qaub dyes thiab cov teeb meem uas yuav tsum tau them sai sai rau thaum tsim khoom. 01 Ntau yam teeb meem ntsig txog
1. Kev faib tawm ntawm cov kua qaub dyes: Muaj zog acid da dej acid dye H2SO4 PH2—4 Tsis muaj zog acid da dej acid dye HAC PH4-6 Tsis zoo da dej acid dye NH4AC PH6-7
2. Kev siv cov kua qaub dyes: dye wool, txhob lo lo ntxhuav thiab nylon hauv acid lossis nruab nrab zoo.
3. Cov yam ntxwv ntawm cov kua qaub dyeing nylon (tsis muaj zog acid da dej):
1) Cov xim nrawm nrawm thiab kev ua haujlwm tsis zoo-tus neeg sawv cev tsim nyog yuav tsum tau ua;
2) Cov xim tsis zoo (xws li soaping fastness) - yuav tsum tau kho kho (tshwj xeeb tshaj yog hom nruab nrab thiab tsaus nti)
3) Dyeing txheej txheem: 50-600C, thawj zaug dyeing-1000C lav-kev kho dej kho. 0 2 Cov txheej txheem dyeing ntawm acid dyes dyeing nylon
1. Dye muaj pes tsawg leeg: Dye X%;
① Acetic acid 1-3 %; Tus neeg saib xyuas qib 0.3-0.5 % PH4–6 1 = 20
② Txhim kho tus neeg sawv cev 2-4% HAC0.5-2% 2. Dyeing method: ib-bath method, ob-bath method (cov kev ua haujlwm tshwj xeeb yog raws li hauv qab no) 1): Ib-da dej ua haujlwm nkhaus PH4-6 da dej piv 1 :20 2): Ob chav da dej ua haujlwm nkhaus ①Dyeing ③ Txhim kho kua tshuaj: Kho tus neeg sawv cev 2-4% Glacial acid 0.5-2% PH4-5
1. Lub luag hauj lwm ntawm cov additives no:
1): Tus neeg saib xyuas qib: (xws li ZJ-RH08 acid printing thiab dyeing tus neeg saib xyuas) Kom ua tiav cov nyhuv dyeing zoo, ntau npaum li cas yuav txo cov xim tuav.
2): Glacial acetic acid Kho tus nqi pH, thiab lub hom phiaj ntawm kev ntxiv ob zaug thaum dyeing yog qhov tsim nyog rau qib dyeing;
3) Kho tus neeg saib xyuas: (ZJ-RH03 acid fixing agent) Txhim kho cov xim ceev ntawm cov kua qaub dyes.
4) Cov khoom siv tshuaj: Ua slurry hauv dej txias, yaj hauv dej kub lossis dej npau npau, do kom huv si kom yaj thiab dilute, thiab lim rau siv.
5) Ntxiv cov ntaub ntawv: Ua tib zoo saib xyuas qhov qeeb qeeb, tsis sib xws, thiab tiv thaiv kev noj zaub mov ntau dhau los ua rau cov xim plooj.
