Sulfur Blue BRN (CI Sulfur Blue 7)

1. Cov ntaub ntawv yooj yim

· Khoom npe: Sulfur Blue BRN (tseem hu ua Sulfur Blue BRN, Sulfur Navy Blue)

· Xim Index: CI Sulfur Blue 7

· Chemical Class: Sulfur dye (ib complex organic compound uas muaj sulfur linkages)

· Daim ntawv lub cev: feem ntau yog xiav tsaus -grey mus rau blackish- xiav hmoov los yog granules.

· Primary Substrate: Cellulosic fibers (tshwj xeeb yog paj rwb, linen, viscose/rayon). Kuj tseem siv tau rau vinal (polyvinyl cawv fiber ntau).

2. Cov yam ntxwv tseem ceeb & kev ua tau zoo

Qhov zoo:

1. Tus nqi-Kev ua tau zoo: Ib qho ntawm cov xim xiav uas pheej yig tshaj plaws muaj, muab tus nqi qis rau ib kg thiab tus nqi dyeing qis.

2. Zoo Tsim-up & Kev Pab: Zoo heev affinity rau cellulose, muab sib sib zog nqus thiab theem ntxoov nrog zoo npog ntawm cov paj rwb tsis paub tab.

3. Kev ntub dej nrawm: Feem ntau pom zoo rau kev ntxuav ceev ceev thiab ntub dej nrawm, ua rau nws haum rau hnyav - cov ntaub ntaub.

4. Mature Technology: Zoo- tsim, yooj yim dyeing txheej txheem dav siv hauv kev lag luam.

5. Classic Xim: Imparts tus yam ntxwv navy xiav, sib sib zog nqus xiav, los yog dull xiav ntxoov ntxoo, uas yog ib txwm siv rau tej yam kev siv xws li denim.

Disadvantages & Considerations:

1. Txwv xim Brilliance: Cov xim yog npub thiab tsis muaj qhov ci ntawm vat, reactive, los yog dyes ncaj qha. Cov xim feem ntau muaj xim liab lossis ntsuab ntsuab.

2. Kev Teeb Meem Nruab Nrab: Lightfastness feem ntau yog nruab nrab rau cov neeg pluag. Kev raug tshav ntuj ntev ntev tuaj yeem ua rau muaj qhov tsis zoo. Qhov no yog ib qho tsis muaj zog ntawm sulfur dyes.

3. Muaj peev xwm rau Tenderizing (Storage Tenderness): Fabrics dyed nrog ib co sulfur dyes (tsawg dua nrog Sulfur Blue dua li nrog Sulfur Black) tuaj yeem ua kev sib tw (tsis muaj zog) thaum lub sij hawm cia nyob rau hauv sov, ntub dej vim acid liberation los ntawm oxidation ntawm residual sulfur. Zoo tom qab-kev kho mob tuaj yeem txo qhov no.

4. Kev txhawj xeeb txog ib puag ncig thiab kev nyab xeeb:

· Cov txheej txheem dyeing: Yuav tsum muaj alkaline txo cov da dej uas siv Sodium Sulfide (Na₂S) thiab Sodium Hydroxide (NaOH), uas ua rau muaj kev phom sij thiab ua rau cov khoom siv tshuaj lom neeg ntau ntxiv.

· AOX Cov ntsiab lus: Qee cov pa roj carbon monoxide dyes tej zaum yuav muaj los yog tsim kom muaj Adsorbable Organic Halides (AOX) thaum lub sij hawm tsim khoom, uas tej zaum yuav tsis ua raws li cov qauv ecological nruj (xws li OEKO-TEX®).

· Cov Hlau Hnyav: Tej zaum yuav muaj cov kab ntau ntawm cov hlau hnyav (piv txwv li, tooj liab) ua impurities.

5. Txwv Xim Ntau Yam: Feem ntau haum rau cov xim sib sib zog nqus xws li xiav, dub, xim av, thiab ntsuab.

3. Dyeing txheej txheem (Cov kauj ruam tseem ceeb)

Sulfur dyes yog dej-insoluble thiab yuav tsum tau txo cov tshuaj mus rau hauv daim ntawv soluble rau daim ntawv thov.

1. Txo / Dissolution: Cov zas xim yog yaj hauv da dej kub (80-95 degree) uas muaj Sodium Sulfide (txo tus neeg sawv cev) thiab Sodium Hydroxide (alkali). Qhov no hloov cov xim rau hauv nws daim ntawv soluble leuco (feem ntau yog cov kua daj lossis ntsuab).

2. Dyeing: Cov ntaub yog immersed nyob rau hauv lub txo dye da dej. Lub leuco compound yog absorbed los ntawm cellulose fibers.

3. Oxidation / Fixation: Tom qab dyeing, cov ntaub yog raug rau huab cua los yog kho nrog oxidizing tus neeg sawv cev (xws li hydrogen peroxide, sodium bromate). Qhov no re-oxidizes leuco compound nyob rau hauv lub fiber, converting nws rov qab mus rau insoluble, tsau pigment daim ntawv, tsim cov xim xiav kawg.

4. Tom qab-Kev kho mob: suav nrog kev ntxuav kom huv si, xab npum (kom tshem tawm cov xim zas xim thiab txhim kho kom nrawm), thiab tejzaum nws muaj kev tiv thaiv kev sib tw (xws li, nrog urea lossis sodium acetate) kom tsis txhob muaj cov kua qaub.

4. Cov ntawv thov tseem ceeb

1. Apparel Fabrics: Cov khoom siv tseem ceeb yog hauv Denim (Jeans) rau classic, vintage, lossis workwear saib. Kuj tseem siv tau rau cov khaub ncaws ua haujlwm, khaub ncaws, tsho, thiab hauv qab xws li.

2. Tsev Textiles & Hnyav Fabrics: Curtains, canvas, upholstery fabrics, thiab tentage.

3. Muaj Textiles: Qhov chaw tsaus nti thiab zoo ntub ceev yuav tsum tau.

5. Kev Ua Lag Luam & Eco-Lwm txoj

Raws li kev cai ib puag ncig, kev txhim kho versions muaj:

· Eco-raws li Sulfur Dyes: Purified kom txo qis AOX thiab cov ntsiab lus hlau hnyav, ua tau raws li cov qauv zoo li OEKO-TEX®.

· Liquid Sulfur Dyes: Ua ntej- txo cov ntaub ntawv ua kua. Lawv muab kev tuav tau yooj yim dua, plua plav tsawg dua, cov txiaj ntsig zoo sib xws, thiab txo cov sulfide noj, tab sis tus nqi siab dua.

Sulfur Blue BRN thiab Sulfur Black yog ob yam khoom tseem ceeb tshaj plaws hauv tsev neeg leej faj dye. Lawv qhia tib cov ntsiab cai ntawm daim ntawv thov thiab cov txiaj ntsig / qhov tsis zoo, sib txawv hauv xim xim.

Cov ntsiab lus

Sulfur Blue BRN yog tus nqi- siv tau zoo thiab muaj zog zas xim rau kev ua tiav cov xim xiav xiav ntawm cov cellulose. Nws muaj zog ntub nrawm thiab tus nqi qis ua rau nws yog ib qho tseem ceeb rau denim thiab hnyav paj rwb ntaub. Txawm li cas los xij, nws qhov nruab nrab lightfastness, dull ntxoov ntxoo, thiab ib puag ncig profile yog cov kev txwv tseem ceeb. Kev xaiv nyob ntawm qhov kawg -siv cov cai, cov hom phiaj ntawm tus nqi, thiab cov qauv ecological. Kev dyeing kom raug thiab tom qab- kev kho mob yog qhov tseem ceeb rau kev ua haujlwm zoo thiab ua haujlwm ntev.
