Bamboo Fiber Npuag Dyeing Thiab Ua tiav Txheej Txheem

Xyoob fiber ntau npuag zas thiab ua tiav cov txheej txheem

Xyoob fiber ntau yog cov khoom siv hauv ib puag ncig ntuj uas muaj qhov ua tau zoo tshaj thiab yog ib yam tshiab ntawm fiber ntau. Xyoob fibrils siv cov txheej txheem ntawm lub cev los cais cov lignin, protein, rog, pectin los ntawm xyoob, thiab tom qab ntawd rho tawm xyoob ntoo los ntawm lawv.

Cov xyoob fiber ntau tuaj yeem khaws cov yam ntxwv ntawm xyoob los ntawm nws tus kheej. Nws yog ib hom ntoo ntsuab cog. Nws yog ib qho yooj yim ntxuav, qhuav, noo noo, txias, dimensionally ruaj khov, du thiab xis. Nws yog qhov zoo nyob, breathable, antibacterial thiab UV tiv taus. Niaj hnub no, nrog kev tsom mus rau kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob, kev tshwm sim ntawm cov fiber ntau tshiab no tuaj yeem txo qhov sib txawv uas tshwm sim los ntawm kev thov zuj zus rau cov paj rwb thiab lwm cov xov paj hauv Suav.

Xyoob fiber ntau zog

1) Qhov ntev ntawm cov xyoob fibrils zoo. Qhov ntev tuaj yeem ua rau qhov ntev uas yuav tsum tau ua rau hom paj rwb, hom ntev thiab hom plaub hau raws li cov neeg siv xav tau;

2) Bamboo fibrils muaj cov khoom zoo dua thermal. Xyoob fibrils pib decompose los ntawm kwv yees li 260 ° C, thiab decompose thiab txiav tawm ntawm ib puag ncig 540 ° C. Lub thermal stability piv nrog cov ramie, uas zoo dua li cov paj rwb fiber, flax fiber thiab xyoob pulp viscose fiber;

3) Tus qauv pib ntawm cov xyoob fibrils yog qis dua li ntawm ntawm cov plaub hau thiab cov plaub hau ntau dua qhov uas ntawm cov xov paj. Nws belongs rau high-lub zog thiab low-stretch fibers thiab muaj high rigidity.

4) Cov xyoob fiber ntau muaj qhov tsis tshua muaj dej noo, ua kom tsis muaj dej noo thiab muaj dej noo zoo, yog li hnav cov ris tsho ua los ntawm xyoob fiber ntau ua kom qhuav thiab xis nyob;

5) Bamboo fibrils muaj cov khoom siv tshuaj tua kab mob zoo thiab tiv thaiv kabmob, ntau dua, zoo dua li ntawm cov xyoob pulp. Ntxiv rau, txij li xyoob fibrils muaj chlorophyll tooj liab sodium, tseem muaj qhov ua tau zoo los tiv thaiv ultraviolet;

6) Cov cuab yeej tshuaj lom zem ntawm xyoob fibrils zoo ib yam li cov khoom ntawm lwm cov cellulose fibers. Lawv tiv taus alkali thiab kua qaub, thiab muaj kuab lom hauv cov muaj zog acids, tab sis lawv kuj ruaj khov rau cov kuab tshuaj ua ke. Muaj hydrophilic noob ntawm macromolecules ntawm xyoob fibrils, tshwj xeeb tshaj yog cov qauv morphological ntawm cov kab nrib pleb hauv cov kab noj hniav ntawm xyoob fibrils, thiab kev ua haujlwm dyeing zoo.

Txheej txheem xyoob fiber ntau ntau lawm

Txoj txheej txheem pretreatment

1) Txheej txheem: soj ntsuam dawb paug → poob qis → pw taus → pw rov qab kub npau → pickling aching tshuaj dawb → ua kom zoo → ziab khaub ncaws.

2) Txheej txheem tshuaj thiab kev mob:

Singeing ob qhov zoo thiab qhov thim rov qab, qhov ceev ceev ntawm 90 ~ 100m / min, kom ntseeg tau tias qhov hu nkauj ntawm lub tshuab ua tiav yog 3 ~ 4.

Kev rov ua xyoob xyoob muaj fiber ntau ntau thiab hnyav dua. Ntxiv qee yam ntxiv rau tus nplawm thaum rov ua noj, thiab ntxiv dag zog rau kev ntxuav kom huv.

Pickling Vim hais tias xyoob fiber ntau ua tiav los ntawm cov txheej txheem ntawm lub cev, qee cov xyoob tawv nqaij tseem nyob ntawm daim fiber, uas cuam tshuam rau cov tsos zoo ntawm daim ntaub. Txoj kev kho cov tshuaj acid acid tuaj yeem ntxiv.

Kev hnoos H2O2 yog 4 ~ 5g / L, pH yog li 10, thiab lub sijhawm yog 40min.

Cov khoom txiav ua ke ntawm NaOH yog 160 g / L thiab lub tsheb nrawm yog 40 m / min thiaj li hais tias cov fibers tau nthuav dav.

Kev ziab khaub ncaws yog cov txheej txheem los xyuas kom meej ntawm kev sib raug zoo ntawm lub ziab ntawm cov khoom lag luam ua tiav. Yog tias lub cev qhov ua tau zoo ntawm cov qib siab mercerized qis tshuab zoo, cov txheej txheem no tuaj yeem raug rho tawm.

2. Dyeing txheej txheem:

Txheej Txheem: Siv xim nti rau xim luam xim raws li piv txwv. Muab cov tshuaj zas xim pleev xim kom txias → Cov xaum me me ua ntej baking kom qhuav → cov tshuaj pleev rau qhov tsau kua fix tsau kua aming ncu → ntxuav → dej → xab npum → kom qhuav.

3. Ua tiav cov txheej txheem:

1) Cov txheej txheem ntws: mos → lub tsev pheeb suab → (pre-shrink) → kuaj cov code rau hauv pob

2) Txheej txheem tshuaj thiab kev mob:

Mos 30g / L;

Ua ntej-shrinking Tom qab kev txiav txim siab dav dav, qhov shrinkage tus nqi ntawm cov khoom tiav tuaj yeem ua kom tau raws li qhov xav tau. Yog tias tus neeg siv khoom yuav tsum tau ntau dua qhov feem ntau shrinkage, nws yuav tsum tau ua ntej ntsws;

Ua ntej-shrinking txheej txheem thiab tej yam kev mob Chav siab 2.5kg / cm2, ceev 30m / min.

Xyoob fiber ntau yog lub ntuj fiber nrog qhov kev ua tau zoo thiab tuaj yeem kho los ntawm cov tshuaj fiber ntau. Txoj kev xaiv txais thiab nkag siab yuav tsum ua kom zoo. Yog tias qhov kev kub siab dhau, lub zog fiber ntau yuav txo qis, thiab qhov dav ntawm lub qhov rooj yuav ntog ntau dhau, uas tsis zoo rau kev ua haujlwm tom qab. Xyoob fibrils yog qhov kev coj ua, thiab kev coj ua yuav tsum tau nqa tawm hauv hom tiaj. Ob qho ntev-ntev thiab zas xim tuaj yeem ua tau. Zam kev ua cov hlua, txwv tsis pub nws yuav ua rau dyeing tsis xws luag (xws li cov hlua xim, nqaij qaib luam taw, thiab lwm yam). Kev xyaum tau ua pov thawj tias lub zog ua kom ruaj khov cov qauv nrog cov xim reactive zoo dua li cov txheej txheem ci. Yog tias qhov tshwj xeeb xaus, xws li enzyme ntxuav thiab los tiv thaiv wrinkle, yog yuav tsum tau tswj, qhov ntau thiab lub sijhawm yuav tsum tau tswj. Cov khoom sib txawv ntawm cov khoom sib txawv yog txawv, tab sis cov txheej txheem feem ntau zoo ib yam
