Nov yog qee qhov kev pabcuam siv hauv polyester dyeing:
Cov neeg nqa khoom
Cov no suav nrog o-phenyl phenol, p-phenyl phenol, diphenyl, monomethyl naphthalene, trichlorobenzene, dimethyl terephthalate, thiab methyl salicylate.
Disperse dyes
Cov no yog cov polar molecules uas muaj anthraquinone lossis azo pawg. Lawv xyaum insoluble nyob rau hauv dej, yog li dispersing agents yog siv kom lawv dispersed nyob rau hauv dej.
Leveling agents
Cov no suav nrog ethoxylate lossis propoxylate ntawm kev hloov phenol, emulsifier, thiab cov cab kuj.
Lwm cov kev pabcuam siv hauv polyester dyeing suav nrog:
Halogenobenzenes, Halogenotoluenes, N-alkylphthalimides, Aromatic carboxylic esters, Methylnaphthalene, Diphenyl ethers, Naphthol ethers, Phenol ethers, thiab Hydroxydiphenyls.
Polyester yog dyed siv disperse dyes nyob rau hauv ib tug acidic nruab nrab ntawm 120 degree los yog 130 degree.
Kev lag luam textile dyeing thiab finishing kev lag luam ua hauj lwm pab lwm yam textile thiab apparel industries los ntawm converting ntxhib thiab unattractive loom fabrics rau hauv cov khoom nrog enhanced xim, tsos, xav thiab kev ua tau zoo haum rau kev siv kawg. Tau ntsib kev sib tw thoob ntiaj teb, cov tuam txhab luam ntawv textile thiab dyeing yog tam sim no lossi siv zog los txhim kho kev lag luam kev sib tw thiab ua kom yooj yim luam ntawv thiab dyeing ua haujlwm kom tau txais txiaj ntsig.
Tam sim no, txoj cai-thawj lub sij hawm dyeing yog ib qho tseem ceeb rau nyob twj ywm nqi-sib tw thiab maximizing tshuab siv thiab throughput. Txawm hais tias niaj hnub dye formulations yog complex thiab tsim los muab kev ua tau zoo ntawm dyed thiab tom qab dyed fabrics, cov kev cai kom tau txais qhov tseeb thawj dyeing impose siab dua xav tau uas yuav tsis tau raws li dye formulation ib leeg. Cov dyers niaj hnub no muaj hmoo uas tuaj yeem tso siab rau ntau yam tshuaj dyeing (feem ntau hu ua auxiliaries lossis dyeing auxiliaries) los pab txhawb kev ua haujlwm tsis tu ncua thiab dyeing txuas ntxiv thiab tsim kom muaj kev pom zoo dyebath rau ib zaug dyeing.
Kev ua kom tsis muaj dej ntau ntxiv uas tsis muaj dej cawv feem ntau siv cov tshuab dyeing yuav tsum tau siv cov khoom siv pov tseg, cov khoom siv ua kua ntau ntxiv uas tuaj yeem nchuav lossis tso rau hauv lub tshuab. Versatility txo cov nqi ntawm cov khoom uas yuav tsum tau yuav, khaws cia, thiab hnyav los yog dispensed, thiab txo cov ntim ntawm cov kua uas yuav tsum tau ntxiv rau lub tshuab. Concentrated kua auxiliaries tseem tuaj yeem thauj thiab khaws cia hauv qhov chaw tsawg dua, uas yog ib qho txiaj ntsig rau ob qho tib si cov khoom siv tshuaj thiab textile dyers. Raws li kev tshawb fawb thiab kev loj hlob, cov neeg muab tshuaj kho kom zoo tshaj plaws ntawm lawv cov auxiliaries siv rau hauv dyebaths. Disposable multifunctional auxiliaries yog li ntawd muaj ntau yam txuj ci thiab tswv yim zoo rau textile dyeing nroj tsuag
Nyob rau hauv cov pa dyeing ntawm polyester thiab polyester / cellulose yarns thiab fabrics, nws yog ib qho tseem ceeb heev uas yuav tsum tau siv non-foaming auxiliaries, tshwj xeeb tshaj yog nyob rau hauv dav hlau dyeing. Tsis tas li ntawd, qhov kub-kub dyeing tej yam kev mob siv ntau qhov yuav tsum tau ntawm lub dispersion zog ntawm disperse dyes nyob rau hauv lub dye cawv. Clariant tau tshaj tawm Eganal PLM liq, cov khoom siv ntau yam uas tsis yog-foaming dyebath auxiliary uas tsis yog tsuas yog muaj cov khoom tawg thiab diffusion-accelerating zog, tab sis kuj tseem muaj zog txhawb zog. Txhim kho dyebath dispersion stability yog qhov tseem ceeb los tiv thaiv kev sib sau ntawm cov dyes disperse thiab lawv lub cev deposition ntawm fiber ntau, uas ua rau tsis zoo rubbing ceev. Eganal PLM liq ua kom zoo nkag mus thiab txhim kho xim yield. Kev dyeing zoo dua rau cov ntaub ntawv uas sib txawv dye affinities tej zaum kuj yuav ua tau los ntawm kev txo lub sij hawm dyeing thiab / los yog dyeing kub.
Eganal PLM liq kuj tuaj yeem siv rau qib dyeing lossis ib nrab stripping ntawm cov dyeing tsis zoo yog tias qhov no tshwm sim. Ib qho txiaj ntsig tseem ceeb rau polyester dyers yog tias Eganal PLM liq tsis cuam tshuam rau kev ntub dej sai thiab muaj tsawg lossis tsis cuam tshuam rau lub teeb xim nrawm. Tsis tas li ntawd, tsis muaj ntxhiab tsw tsw phem thaum lub sij hawm dyeing lossis cua sov kom qhuav piv rau lwm yam khoom siv ua lag luam.
