Cov Nqa Cov Teeb Meem Zoo Ntawm Knitting Dyeing Thiab Cov Khoom Ua tiav Thiab Kev Xaiv Cov Tshuaj Ntxiv

Cov teeb meem tshwm sim zoo ntawm knitting dyeing thiab xov khoom thiab xaiv cov additives

Tam sim no, txoj kev lag luam dyeing thiab xov tau zoo heev thiab cov kev lag luam no tau zoo heev. Txawm li cas los xij, nrog kev nthuav dav ntawm cov ntim ntau lawm, cov knitting thiab dyeing factories ntawm ntau qhov chaw qhia txog qhov zoo ntawm dyeing thiab xov, thiab cov kab mob ntawm dyeing thiab xov khoom yog qhov zoo ntawm dyeing thiab xov khoom. Lub hauv paus tseem ceeb kuj tseem tuaj yeem qhia txog qib kev lag luam qib, qib kev tswj hwm thiab khoom siv thev naus laus zis ntawm kev zas thiab ua tiav cov tshuab. Hauv kev tsim khoom, vim yog cov ntaub grey, cov khoom lag luam ib nrab, khoom siv, qib kev ua haujlwm thiab kev coj ua, cov khoom zoo ntawm cov zas khoom, thiab lwm yam, cov teeb meem zoo yuav tshwm sim. Qhov kev xaiv thiab zoo ntawm cov quav tso quav ncaj qha cuam tshuam rau qhov zoo ntawm cov dyeing thiab cov khoom tiav. Taw rau cov teeb meem ntawm cov teeb meem niaj hnub zoo ntawm kev zas thiab ua tiav cov khoom ntawm cov ntawv knitted thiab kev sib raug zoo ntawm kev xaiv ntawm cov quav dej quav cawv.

1 Ua ntej kho cov teeb meem muaj txiaj ntsig zoo thiab xaiv cov quav quav yeeb tshuaj

Qhov zoo ntawm kev kho ua ntej (kev coj ua tshuaj dawb) tsis yog tsuas yog cuam tshuam rau qhov zoo ntawm cov khoom tiav ntawm cov tshuaj dawb, tab sis kuj yog ib qho khoom lag luam ib nrab, nws yuav ncaj qha cuam tshuam rau qhov zoo ntawm dyeing, luam ntawv thiab xov. Qee cov kws tshaj lij hais tias 70% ntawm cov teeb meem zoo ntawm kev zas thiab cov khoom tiav yog los ntawm kev kho ua ntej tsis zoo, thiab muaj qee qhov laj thawj. Qhov zoo ntawm dyeing thiab xov yog cuam tshuam nrog cov grey npuag, muaj feem xyuam rau cov khoom siv thiab kev ua haujlwm, muaj feem xyuam nrog cov txheej txheem thev naus laus zis thiab kev tua, muaj feem xyuam nrog cov zas, thiab cuam tshuam nrog cov ntu pabcuam. Peb tsom ntawm tus neeg ntawm kev noj tshuaj ntxiv.

1.1 Whiteness thiab cov plaub hau tsis zoo ua haujlwm

Cov duab tsis zoo, nrog rau cov tawv dawb tsis huv, tsis sib luag thiab cov plaub hau ua haujlwm tsawg dua 8 ~ 10cm / 30min. Qhov no muaj feem xyuam rau qhov zoo ntawm cov ntawv knitted. Piv txwv, paj rwb qis muaj ntau cov ntsiab lus, thiab feem ntau dawb thiab plaub hau tsis yooj yim ua. Ntawm chav kawm, feem ntau Qhov tseem ceeb tshaj plaws yog cov txheej txheem kev txhim kho thiab xaiv cov additives. Hauv kev tsim cov txheej txheem:

Tus nqi ntawm 1H202 thiab NaOH yuav tsum muaj txaus.

H202: tsis tsuas yog ua lub luag haujlwm ntawm tshuaj dawb tso xim tom qab kev kho mob ua ntej, tab sis kuj muaj cov nyhuv de-doping (suav nrog lub plhaub cottonseed), qhov ntau ntawm H202 tsis txaus (suav nrog kev rhuav tshem nrawm), dawb paug tsis tuaj yeem lav, NaOH tsis tsuas yog muab H202 tshuaj dawb tso rau Alkalinity (PH), thiab nrog tus sawv cev scouring, qhov siab tshaj plaws ua kom tsis zoo, qhov nyiaj ntawm NaOH tsis txaus, qhov tsis meej yog qhov tsis zoo, cov nyhuv quav tsis tuaj yeem ua tau raws li qhov yuav tsum ua ntej, tau kawg, tsis dawb yuav tsis tau qhov xav tau, yog li tus nqi ntawm H202 thiab NaOH Nws tuaj yeem hais tias nws yog thawj qhov kev lag luam kom ntseeg tau tias kev ua dawb thiab tag nrho;

2 siv cov khoom zoo ntawm tus sawv cev:

Cov kev ua tau zoo ntawm tus neeg saib xyuas xws li ntxuav, emulsifying, dispersing thiab infiltrating yuav tsum zoo tshaj plaws kom paub meej qhov kev tshem tawm ntawm impurities thiab xyuas kom meej thiab dawb nyhuv. Txawm li cas los xij, qhov zoo ntawm cov txiab cov khoom ua rau ntawm kev ua lag luam yog tsis sib xws, peb yuav tsum xaiv cov khoom lag luam nrog cov txiaj ntsig zoo tshaj plaws. Tsis tsuas yog cov permeability thiab cov ntsiab lus ruaj ntseg raug ntsuas, tab sis kev nkag mus tsuas yog ib qho kev xav;

3 pa tshuaj ua kom haum stabilizer thiab chelating dispersant:

Ob qhov ntxiv no yog siv los txhim kho cov dej kom zoo, adsorb thiab cov khoom siv hlau tsis yooj yim xws li Fe3 + hauv dej, thiab tiv thaiv cov hlau ions los ntawm kev cuam tshuam kev cuam tshuam sai thiab tsis muaj txiaj ntsig ntawm H202. Yog tias H202 decomposes sai sai, nws qhov kev dawb thiab tag nrho yuav tsis tiav. Cov kev xav tau, tib lub sijhawm yuav ua rau cov ntaub npuag los yog lub qhov, yog li kom ua tiav cov tawv nqaij thiab cov plaub hau, cov pa tshuaj ua kom lub cev khov kho yuav tsum xaiv ntau yam zoo, hauv kev xaiv yuav tsum tsom mus rau qhov kev txiav tawm ntawm H202. Qhov sib ntxiv ntawm chelating dispersing tus neeg sawv cev tsis tsuas yog chelate hlau lossis cov zoo li, tab sis kuj chelate ntau yam impurities hauv dej, kom lub impurities tsis rov ua dua cov ntaub thiab ua rau whiteness thiab tsaus tshauv, yog li chelating dispersing tus neeg sawv cev tsis yog tsuas yog Xav txog nws chelation rau hlau ions thiab tseem xav txog nws lub zog dispersing;

4 Txheej txheem txheej txheem: Nws yuav siv sijhawm thiab qhov kub thiab txias los cuam tshuam tus neeg sawv cev tiv thaiv nrog cov impurities. Yog tias cov xwm txheej tsis txaus, cov pigment thiab impurities tsis tau muab tshem tawm kom zoo, thiab qhov dawb thiab qhov txiaj ntsig tsis tuaj yeem ua tiav:

5 Ntxuav: Nws yog ib qho tseem ceeb heev uas yuav tau ntxuav tom qab tshuaj dawb. Nws yog qhov tsim nyog los ntxuav thiab tshem tawm cov impurities kom paub meej dawb thiab plaub.

1.2 Lub xov paj Cottonseed hull tshem tawm tsis huv

Qhov kev tshem tawm ntawm lub tsev pheeb suab hauv lub cev hull feem ntau tsuas yog tso siab rau kev nthuav dav thiab o ntawm cottonseed hull nyob rau hauv qee yam kev mob, thiab tom qab ntawd tshem tawm lub tsev pheeb suab hauv cottonseed hull los ntawm qee lub tshuab ntxuav. Qhov kev tshem tawm ntawm kev tsis huv yog feem ntau yog los ntawm qhov ntsuas kub tsis txaus thiab lub sijhawm, yog li nws yuav tsum tau ua kom txaus ntawm qhov kub. Lub sijhawm tuaj yeem ua tiav cov hle cov hleb hle. H202 thiab tus neeg saib xyuas scouring tuaj yeem pab tshem tawm ntawm cov pob zeb hle khoom. Yog li ntawd, yuav tsum muaj qee qhov ntsuas kub thiab sijhawm nyob rau hauv qhov qauv ua ntej kom ntseeg tau tias qhov tshem tawm cov paj rwb husks. Tib lub sijhawm, NaHS03 lossis guanidines tuaj yeem raug ntxiv los pab. Cottonseed hulls tau muab tshem tawm.

1.3 Qhov thiab puas

Qhov laj thawj tseem ceeb yog nyob ntawm Fe3 +, Cu2 + thiab lwm yam hlau ions hauv H202 tshuaj dawb tso rau hauv da dej lossis rau ntawm daim ntaub saum npoo, ntxiv rau qhov tawm ntawm lub qhov suab, qhov tsoo thaum ua tiav, qhov qub qhov hauv daim ntaub grey, thiab lwm yam hlau ions catalyze. qhov kev rhuav tshem ntawm H202 rau ua kom sai sai, ua rau muaj fiber ntau txhuam. Yog tias cov hlau ions (xws li xeb, thiab lwm yam) dhau lawm ntau qhov chaw hauv ib qho chaw, cov xov thiab cov xov tsis yooj yim thiab tsim lub qhov. Yog li, H202 tshuaj dawb yuav tsum xaiv cov pa tshuaj zoo rau cov tshuab kom ruaj khov thiab chelating dispersants kom yooj yim, cov ntaub adsorb thiab cov tshuaj ntxuav dej. Cov khoom siv tooj hlau hauv cov hlau thaiv cov H202 los ntawm kev ua kom tiav sai dhau ua rau cov qhov lossis nkig. Yog tias lub hauv paus xa mus rau tshuaj dawb, nws yog ib qho tsim nyog yuav tsum xyuas kom meej tias lub alkali tsis muaj qhov tsis muaj zog xws li xeb.

Yog lawm, daim ntaub nrog alkali (tsis yog alkali) lossis nrog kua qaub (de-acidized) kuj tseem tuaj yeem ua rau nkig. Nyob rau tib lub sijhawm, nyob rau qhov xwm txheej ntawm qhov kub nrog alkali, cov ntaub yuav txhaws nyob rau hauv lub xub ntiag ntawm huab cua, uas tuaj yeem tiv thaiv los ntawm kev ntxiv cov qaug zog uas tsis muaj zog xws li NaHS03.
