Daim ntawv thov ntawm Basic Dyes hauv Silk thiab Tawv Dyeing

Cov ntsiab cai thiab tsim nyog

Basic dyes (cationic dyes) tshuav lawv cov brilliance thiab siab tinctorial zog rau lawv lub peev xwm los tsim ionic bonds nrog tsis zoo them substrates.

· Silk - Raws li ib tug protein fiber, txhob lo lo ntxhuav yog ib tug zoo nqi nyob rau hauv acidic tej yam kev mob, uas nyiam nyiam cov xim yooj yim. Dyeing feem ntau yog ua nyob rau hauv ib tug qaug zog acidic da dej (pH 4-5) nyob ib ncig ntawm 90-95 degree. Thaum cov xim yield yog zoo heev, lub ntsiab drawbacks yog tsis zoo ntxuav ceev ceev, tsis muaj hws ceev ceev, thiab feem ntau tsis tshua muaj teeb ceev ceev tshwj tsis yog tias muaj kev kho tshwj xeeb.

· Tawv - Qhov tsim nyog ntawm cov xim yooj yim yog nyob ntawm txoj kev tanning nkaus xwb. Zaub - tanned tawv yog tsis zoo them thiab nkag tau yooj yim dyes, muab sib sib zog nqus, kaj ntxoov. Nyob rau hauv sib piv, chrome-tanned tawv nqa ib tug zoo nqi thiab repels yooj yim dyes; acid dyes yog siv los hloov. Hloov kho glutaraldehyde-tanned tawv kuj tuaj yeem ua tiav nrog cov xim yooj yim.

Silk Dyeing: Txheej txheem thiab kev txhim kho ceev

Cov txheej txheem dyeing ib txwm siv rau 1% cov xim yooj yim (owf) nrog 2% acetic acid thiab 1% sodium acetate hauv da dej ntawm cawv piv ntawm 1:80. Qhov kub yog tuav ntawm 90-95℃rau li 45 feeb.

Vim tias qhov ntub dej nrawm ntawm cov xim yooj yim ntawm cov ntaub lo lo ntxhuav yog qhov tsis tshua muaj, kev lag luam dyeing feem ntau yuav tsum tau kho tom qab. Mordanting nrog tannic acid thiab tartar emetic (potassium antimonyl tartrate) yog ib txoj hauv kev los txhim kho kev ntxuav thiab hws ceev. Tsis ntev los no, aminosulfonic acid grafting tau pom tias yuav ua rau kom cov dye uptake los ntawm ib qho tseem ceeb ntawm 1.4-1.5 thaum txhim kho lub teeb nrawm mus rau qib piv rau ntawm acrylic fibers. Cov kab xev grafted yog luam tawm los yog padded nrog ib tug muab tshuaj txhuam uas muaj aminosulfonic acid, urea, thiab starch, ces steamed ntawm 120-130℃ua ntej dyeing.

Tawv Dyeing: Xaiv thiab Daim Ntawv Thov

Rau zaub-tanned tawv, cov xim yooj yim yog siv ncaj qha rau hauv cov da dej aqueous. Qhov kev pom zoo yog pib pH ntawm 3.3-3.8 thiab lub sijhawm dyeing ntawm 50-60 feeb ntawm qhov kub ntawm chav tsev kub txog 60 degrees. Txog rau qhov kawg ntawm cov txheej txheem, pH tau tsa (piv txwv li, los ntawm kev ntxiv alkali) los txhawb kev qaug zog thiab kho.

Basic dyes muab tawv tshwj xeeb ci ntxoov ntxoo nrog kev nkag mus zoo tswj, tab sis lawv ceev rau lub teeb thiab rubbing tsuas yog nruab nrab. Vim li no, lawv feem ntau siv rau cov khoom tawv qis-rau nruab nrab tshwj tsis yog siv cov cationic kho tus neeg sawv cev tom qab dyeing los txo cov ntshav thiab txhim kho cov ntub dej sai.

Hauv kev lag luam tawv, cov xim yooj yim yog tsim rau hauv D-series cov khoom lag luam rau nruas dyeing (immersion) thiab SP-series rau cov tshuaj tsuag kom tiav, kom ntseeg tau tias daim ntawv thov sib txawv ntawm cov txheej txheem tsim khoom sib txawv.

Kev xav txog tswv yim

· Cov kev txwv ceev ceev - Txawm hais tias lub substrate, cov xim yooj yim feem ntau muaj lub teeb tsis zoo. Yog tias cov khoom siv dyed yuav raug tshav ntuj, UV absorber los yog lwm chav kawm dye (xws li reactive dyes rau silk los yog acid dyes rau chrome tawv) yuav tsum xav txog.

· Cov kev cai txwv – Tej yam xim yooj yim, tshwj xeeb tshaj yog Malachite Green (Basic Green 4), raug txwv nruj rau hauv cov ntawv thov uas tuaj yeem tiv tauj cov zaub mov, dej haus, lossis tib neeg lub cev (xws li tawv rau ntim khoom noj).

· Kev xaiv cov txheej txheem - Rau cov txhob lo lo ntxhuav, yog tias yuav tsum tau ntxuav ceev ceev, yuav tsum tau xaiv ib kauj ruam mordanting los yog ib tug reactive dye. Rau cov tawv nqaij, nco ntsoov xyuas cov txheej txheem tanning ua ntej xaiv cov xim yooj yim: lawv zoo tagnrho rau cov tawv nqaij tawv, tab sis tsis haum rau tawv chrome-tanned.

Yog tias koj qhia meej cov ntaub lo lo ntxhuav (ntshiab txhob lo lo ntxhuav los yog sib tov) los yog cov txheej txheem tanning siv rau koj cov tawv nqaij, kuv tuaj yeem muab cov kev ua haujlwm ntau dua.
