Kev sib raug zoo ntawm Sulfur Black thiab Direct Black

Sulfur Black thiab Direct Black yog ob hom sib txawv ntawm cov xim dub siv rau xim cov ntaub ntawv. Lawv tau nkag siab zoo tshaj plaws raws li kev sib txuas sib txuas, tsis yog kev sib txuas ntawm ib leeg. Xav txog lawv li ob yam cuab yeej sib txawv rau kev ua tiav cov xim dub, txhua tus muaj nws tus kheej cov txheej txheem, qhov zoo, thiab qhov tsis zoo.

1. Qhov sib txawv hauv Chemistry thiab Daim Ntawv Thov

· Sulfur Black belongs rau chav kawm sulfur dye. Nws cov qauv tshuaj yog complex thiab muaj sulfur linkages. Cov yam ntxwv tseem ceeb yog tias nws yog insoluble hauv dej. Txhawm rau siv nws, nws yuav tsum ua ntej txo cov tshuaj siv tshuaj sulfide alkali (xws li sodium sulfide). Cov txheej txheem no hloov nws mus rau hauv dej -soluble "leuco" compound uas tuaj yeem nqus tau los ntawm fiber ntau. Tom qab nqus tau, cov ntaub yog raug rau huab cua, uas oxidizes cov xim rov qab mus rau hauv nws cov insoluble daim ntawv, mus tas li cuab nws nyob rau hauv lub fiber.

· Direct Black belongs rau chav kawm dye ncaj qha. Nws muaj qhov txhais ntau dua, feem ntau ntev - saw molecular qauv. Nws lub ntsiab kom zoo dua yog hais tias nws yog ncaj qha soluble nyob rau hauv dej, yuav tsum tsis muaj complex tshuaj txo. Cov dye molecules txuas rau cov fiber ntau los ntawm lub cev tsis muaj zog xws li hydrogen bonding thiab van der Waals rog. Qhov no ua rau cov txheej txheem yooj yim, tab sis daim ntawv cog lus tsis muaj zog.

2. Qhov sib txawv ntawm kev ua tau zoo thiab cov khoom siv

· Sulfur Black yog lub npe hu rau nws:

· Tus nqi qis heev, ua rau nws yog ib qho kev lag luam zoo tshaj plaws dub dyes muaj.

· Lub dav hlau zoo heev, txhais tau tias nws ua rau qhov tob tob, ntom ntom ntom.

· Zoo ntub dej ceev ceev. Txawm li cas los, nws muaj ib tug tseem ceeb drawbacks:

· Tsis zoo lightfastness, txhais tau tias nws yuav ploj mus sai heev thaum raug tshav ntuj.

· Nws tuaj yeem ua rau muaj fiber ntau, ua kom tsis muaj zog ntawm cov ntaub, yog tias tsis ua tiav thiab khaws cia zoo.

· Tsob tshuaj ntau lawm thiab dyeing tsa ib puag ncig kev txhawj xeeb vim sulfide nyob rau hauv cov dej khib nyiab.

· Direct Dub yog khoom plig rau nws:

· Yooj yim ntawm daim ntawv thov, raws li nws dissolves yooj yim nyob rau hauv dej tsis txo.

· Ntau qhov ntxoov ntxoo thiab zoo xim ci ntsa iab. Nws qhov tsis muaj zog loj yog:

· Kev ntub dej tsis zoo. Cov ntaub dyed nrog Direct Black zoo li los ntshav thiab poob xim thaum ntxuav tshwj tsis yog kho nrog tus neeg saib xyuas tshwj xeeb tom qab.

· Qee hom tau raug txwv vim muaj kev tswj hwm ib puag ncig.

3. Cov ntawv thov sib txawv hauv kev lag luam Textile

· Sulfur Black dominates daim ntaub ntawv uas tus nqi thiab ib tug sib sib zog nqus dub yog qhov tseem ceeb, thiab lightfastness tsis tseem ceeb. Nws lub cim tseem ceeb tshaj plaws yog siv hauv cov denim dub (dub ris). Nws kuj yog dav siv rau canvas, industrial fabrics, thiab yarns.

· Direct Black feem ntau yog xaiv rau qis dua - cov khoom nqi uas ntub dej siab - ceev tsis yog qhov yuav tsum tau ua. Koj yuav pom nws nyob rau hauv ib co knitwear, tsev textiles, thiab rau dyeing ntawv thiab tawv.

Xaus

Hauv cov ntsiab lus, kev xaiv ntawm lawv los ntawm qhov kawg ntawm cov khoom yuav tsum tau ua. Sulfur Black yog tus kws tshaj lij rau pheej yig, ultra-dub tob ntawm cov paj rwb rugged, zoo meej rau qhov zoo ntawm cov denim dub. Direct Black yog tus kws tshaj lij rau daim ntawv thov yooj yim ntawm cov khoom uas nquag ntxuav, hnyav tsis xav tau.

Rau siab -cov khaub ncaws zoo uas xav tau kev ntxuav zoo thiab lub teeb nrawm, kev lag luam feem ntau txav dhau ob qho tib si mus rau ntau cov xim zoo li Reactive Black. Txawm li cas los xij, vim nws qhov txiaj ntsig tsis sib xws, Sulfur Black tseem yog tus huab tais tsis sib haum xeeb hauv nws qhov tshwj xeeb, siab - ntim niche.
