Dab tsi yog Reactive Dyes?

Dye / Dyestuff yog ib qho tseem ceeb tshaj plaws hauv kev lag luam textile thiab lwm yam lag luam.Nws yog ib qho sib xyaw uas tuaj yeem txuas rau txhua daim ntaub los pleev xim rau cov ntaub.Muaj ntau yam dyes nyob rau hauv kev ua lag luam xaiv los ntawm, tab sis cov nyiam tshaj plaws yog cov tshuaj dyes ruaj khov uas tuaj yeem xim cov ntaub hauv lub sijhawm luv.Ob yam tseem ceeb tshaj plaws uas ua rau cov xim zoo nkauj yog qhov kub thiab lub sijhawm.

Kev noj cov dyes yog ib qho tseem ceeb qhia rau kev nkag siab txog kev loj hlob ntawm kev lag luam hauv zej zog.Hauv kev txhim kho kev lag luam xws li Is Nrias teb thiab Tuam Tshoj, kev siv cov dyes loj hlob sai vim kev txhim kho kev ua haujlwm, kev loj hlob hauv nroog, thiab cov pej xeem nthuav dav.

Vim muaj peev xwm paub qhov txawv ntawm qhov chaw ntawm cov xim thiab yuav siv li cas, muaj ntau hom dyes.Dyes tau los ntawm tej yam ntuj tso xws li nroj tsuag los yog paj yog hu ua natural dyes, tsis yog hluavtaws dyes.Ib yam li ntawd, muaj cov dyes uas tuaj yeem paub qhov txawv raws li lawv daim ntawv thov.Ib qho ntawm feem ntau siv variants raws li lawv daim ntawv thov yog reactive dyes.

Qhov zoo ntawm reactive dyes:

1. Vim tias nws muaj peev xwm ua rau muaj kev cuam tshuam nrog qhov nruab nrab, nws muab cov dyes reactive ib qho txiaj ntsig zoo vim tias lawv ua tau ntev dua thiab pom qhov sib txawv.Cov yam ntxwv no ua rau nws muaj txiaj ntsig zoo hauv kev txwv cov xim thiab cellulose xim.

2. Muaj lwm qhov muaj txiaj ntsig zoo ntawm cov dyes reactive, uas yog, nws txoj kev ntub dej nrawm, uas ua tiav los ntawm cov txheej txheem xim zoo thiab ncaj qha.

3. Reactive dyes yog tsim rau dyeing tshiab cellulose fibers xws li lyocellfibers.

4. Yooj yim los ntxuav: Fibers dyed nrog reactive dyes tuaj yeem dyed yam xyuam xim nrog cov khaub ncaws dawb yam tsis muaj kev phom sij ntawm dyeing.

Txawm hais tias kev siv cov xim reactive dyes muaj ntau qhov zoo, kuj tseem muaj qee qhov tsis zoo, xws li kev cuam tshuam ntawm cov xim reactive rau ib puag ncig.Txawm li cas los xij, reactive dye manufacturers hauv Is Nrias teb thiab thoob ntiaj teb tau nqis peev ntau lub zog thiab cov peev txheej hauv kev tshawb fawb los pab lawv tsim cov khoom lag luam ecologically rhiab heev thaum muab cov neeg siv khoom muaj txiaj ntsig thiab txuas ntxiv.Lwm qhov kev sib tw uas ntsib kev lag luam suav nrog kev nrhiav cov neeg txawj thiab txawj ua haujlwm, tsoomfwv cov cai, thiab cov nqi tsim khoom.Txawm hais tias kev lag luam muaj lub neej yav tom ntej zoo, nws yog ib qho tseem ceeb uas yuav tsum ua kom muaj kev vam meej hauv txhua qhov chaw saum toj no kom tsis txhob muaj kev cuam tshuam.

Lub reactive dyeing tshuaj reacts nrog cov cellulose, ua ib tug covalent daim ntawv cog lus ntawm cov dye molecule thiab cellulose.

Puas yog reactive dyes yog ib puag ncig tus phooj ywg?

Yog tias peb xav txog kev siv cov dyes reactive, ces cov dyes reactive yuav tsum yog ib puag ncig tus phooj ywg.

Dab tsi yog kev siv covalent bonds hauv reactive dyes?

Covalent daim ntawv cog lus yog siv nyob rau hauv reactive dyes kom lawv siab ceev ceev.
