Kev txhim kho ntawm Reactive Dyeing Technology

Kev txhim kho ntawm Reactive Dyeing Technology

Nyob rau hauv xyoo tas los no, cov txheej txheem dyeing tshiab ntawm reactive dyeing tau tsim sai heev.Cov txheej txheem reactive dyeing tam sim no muaj xws li: reactive dye pad dyeing thiab luv steaming dyeing, reactive dye dip dyeing luv txheej txheem, reactive dye qis kub thiab txias ncoo batch dyeing, thiab nruab nrab kho tus neeg saib xyuas dyeing, Reactive dye low-sald thiab ntsev-dawb dyeing, siv "hloov ntsev" reactive dye low-salt dyeing, reactive dye low-alkali thiab nruab nrab dyeing.

1.Reactive dye pad dyeing thiab ntub luv chav dyeing.Pad dyeing yog ib qho tseem ceeb dyeing txoj kev ntawm reactive dyes.Txawm li cas los xij, tom qab cov ntaub yog impregnated nrog cov ntaub qhwv dye tov, qhov nruab nrab kom qhuav yog yuav tsum tau ua kom yooj yim rau tom qab steaming, los yog ua kom ceev ceev thaum lub sij hawm ci thiab kho.Thiab txo cov dye hydrolysis, thiab tau txais kev txhim kho siab thiab xim ceev ceev.Kev ziab ziab nruab nrab yuav ua rau muaj teeb meem ntau: kev siv hluav taws xob, kev siv hluav taws xob ntau thaum ziab cov ntaub ntub dej kom evaporate dej;dyes yog nquag tsiv teb tsaws thaum ziab, ua rau cov xim sib txawv thiab txo cov xim ceev, thiab dyeing reproducibility kuj tsis zoo;Kev ziab tom qab dipping cov tshuaj dyeing tsis tsuas yog ntxiv cov txheej txheem ua haujlwm thiab tsis yooj yim rau kev tswj hwm, tab sis kuj thaum cov ntaub qhuav yog steamed, cov dyes thiab tshuaj yuav tsum nqus dej kom yaj dua.Cov ntaub qhuav yuav tawm cua sov thaum nws nqus cov dej noo, ua rau overheating, uas yog kev puas tsuaj rau dyeing thiab kho.Yog li ntawd, steaming yog lub hom phiaj mus sij hawm ntev uas tib neeg nrhiav.Nws yog qhov nyuaj heev rau chav dyed fabrics.Ua ntej, cov ntaub ntub dej ncaj qha steamed.Vim hais tias cov dej noo absorbs cua sov thiab evaporates, cov ntaub cua sov tus nqi yog qeeb, uas prolongs lub steaming thiab kho lub sij hawm;Thib ob, cov ntaub ntawv muaj cov dej noo ntau (feem ntau cov kua dej tom qab padding yog 60% mus rau 70%), nyob rau hauv cov txheej txheem ntawm steaming thiab cua sov, cov reactive dyes ntawm cov ntaub yuav undergo ib tug loj npaum li cas ntawm hydrolysis, uas txo cov fixation. tus nqi thiab xim ceev ceev.Cov dej noo ntawm cov ntaub muaj ntau lub xeev, uas tuaj yeem muab faib ua ob pawg: fiber ntau absorbed dej thiab dej dawb ntawm cov ntaub.Cov dej sib xyaw ua ke uas nqus dej (tsuas yog sib txuas rau cov saw hlau fiber ntau los ntawm hydrogen bonds) kuj hu ua dej tsis khov (nws qhov chaw khov yog qis dua 0 ° C).Cov ntsiab lus ntawm cov dej no tsis ntau, thiab qhov tshwm sim ntawm cov tshuaj tiv thaiv nrog dyes kuj tsawg dua, vim tias nws tsis tuaj yeem txav mus los.Ib feem ntawm cov dej absorbed yog nyob rau hauv fiber pores.Cov pores fiber ntau yog nyias.Cov dej no tsis yooj yim ntws tawm, yog li nws tseem hu ua dej khi.Nws cov tshuaj tiv thaiv nrog dyes kuj tsawg.Txawm hais tias ib feem ntawm cov dej dawb sab nraum cov fiber ntau yog nyob rau hauv inter-fiber capillary thiab tsis yooj yim rau ntws vim cov nyhuv capillary, feem ntau ntawm nws tuaj yeem ntws dawb.Cov dej hauv ob lub xeev no sab nraum cov fiber ntau yooj yim rau cov tshuaj zas xim.Thaum cov dye yog siab, nws yuav tsum tau kom cov dye tsis dhau ib tug loj npaum li cas ntawm hydrolysis, thiab ceev fixation cov tshuaj tiv thaiv tshwm sim tom qab ncav cuag ib tug txaus kub.Vim li no, tus neeg sawv cev alkali tsim nyog rau kev siv yuav tsum tsis muaj zog, lossis alkalinity yuav tsum tsis txhob muaj zog thaum cov dej noo ntawm cov ntaub siab (xws li cov alkali sib xyaw ntawm cov dej qab zib los yog dej qab zib tshauv thiab qee cov tshuaj alkali), yog tias qis alkali. los yog nruab nrab fixation yog ua Cov nyhuv yuav zoo dua.Cov kev tshawb fawb tau pom tias kev siv cov tshuaj kho nruab nrab los kho cov xim muaj txiaj ntsig zoo ntawm 120 ~ 130 ℃ lossis 180 ℃.

2.Short reactive dye dip dyeing txheej txheem shortens cov reactive dyeing txheej txheem, txhim kho efficiency ntau lawm, txuag zog, txuag dej, thiab txo cov dej phwj tuaj.Nthuav luv chav dyeing yog luv luv txheej txheem dyeing txheej txheem ntawm pad dyeing.Cov txheej txheem dyeing luv luv ntawm dip dyeing tseem yog qhov tseem ceeb ntawm kev tshawb fawb hauv xyoo tas los no, txhim kho cov cuab yeej siv, ua kom lub sij hawm dyeing luv luv, thiab qhov tseem ceeb tshaj, kev tswj kom tsim nyog ntawm cov txheej txheem dyeing, thiab kev tswj lub computer tsis siv neeg tuaj yeem txo qhov dyeing, kho thiab ntxuav. sij hawm.Nyob rau hauv xyoo tas los no, ntau lub tuam txhab tsim cov dyeing tau tsim cov txheej txheem dyeing sai sai txhawm rau txhawb lawv cov khoom.Lub hauv paus ntawm cov txheej txheem dyeing ceev yog xaiv dyes tsim nyog raws li lawv cov yam ntxwv, thiab ua kom luv tag nrho lub sij hawm dyeing nyob rau hauv lub premise ntawm kom ntseeg tau zoo leveling thiab reproducibility.Siv kev ntsuas ntsuas thiab txuas ntxiv txuas ntxiv, uas tuaj yeem txo lub sijhawm.Zoo heev txuag dyes, alkalis thiab ntsev, thiab txo cov dej phwj tuaj.Qee cov txheej txheem tseem tuaj yeem tswj kev ntxuav tom qab dyeing kom txuag dej ntxiv thiab txo cov dej phwj tuaj.Qee cov dyeing lossis cov cuab yeej tsim khoom kuj tau tsim ntau yam kev tswj hwm dyeing software.
