Kev luam ntawv, raws li qhov txawv ntawm dyeing, cov txheej txheem uas cov dye los yog txheej yog siv rau ib daim ntaub los ua ib tug qauv.

Xyoo 1784, peb tus neeg Fab Kis tau tsim lub ntiaj teb thawj lub tshuab luam ntawv paj rwb.

Tshaj li 230 xyoo dhau los, tshuab luam ntawv tau tsim ntau yam.Niaj hnub no, encyclopedia xiaobian yuav xyuas cov hom luam ntawv

I. Kev faib tawm raws li txheej txheem luam ntawv:

1. Direct printing (Over print, ntub luam ntawv)

Direct printing yog ib hom luam ntawv ncaj qha rau ntawm cov ntaub dawb los yog ntawm cov ntaub uas tau ua ntej dyed.Lub tom kawg yog hu ua overprint (tseem hu ua hauv qab luam ntawv), thiab tau kawg cov ntawv luam tawm ntau dua li xim hauv qab.Kwv yees li 80% ntawm cov ntaub ntawv luam tawm ntawm lub khw yog luam tawm ncaj qha.(Ntawm no ncaj qha luam ntawv feem ntau yog hais txog kev luam ntawv dyes, siv kom paub qhov txawv ntawm cov xim luam ntawv hauv qab no)

Lus Nug: Yuav ua li cas paub qhov txawv ntawm cov xim dawb los ntawm cov xim xim?

Yog tias cov xim keeb kwm yav dhau ntawm cov ntaub yog tib qhov ntxoov ntxoo ntawm ob sab (vim yog cov xim dye) thiab cov ntawv luam tawm ntau dua li cov xim tom qab, ces nws yog lub hau npog, txwv tsis pub nws yog xim dawb.

2. Tshem tawm luam ntawv

Xaiv tsis dyeing rau dyeing lub hauv paus ntawm paug muab tshuaj txhuam, tiv thaiv kom qhuav, siv cov tshuaj ntxuav tes uas muaj tus neeg sawv cev tawm los yog muaj kev tiv thaiv kom tawm tib lub sij hawm tsim thiab xim ntawm cov xim luam ntawv luam tawm, tom qab ua tiav, luam tawm hauv av raug rhuav tshem thiab lub decolorization ntawm dyeing, xim ntawm lub ntiaj teb tsim dawb qauv (hu ua dawb paug) los yog xim qauv tsim los ntawm tus tsim thiab xim dyes dyeing (hu ua xim printing).Kuj hu ua rub dawb lossis xim rub.

Hauv kev sib piv rau kev luam ntawv ncaj qha, cov nqi tsim khoom ntawm cov ntaub ntawv luam tawm yog siab, thiab kev saib xyuas zoo thiab kev txiav txim siab yuav tsum tau coj los tswj kev siv tus neeg saib xyuas kom txo qis.

Lus Nug: Yuav ua li cas kom paub qhov txawv ntawm cov ntaub yog cov luam tawm?

Yog hais tias cov ntaub muaj tib xim ntawm ob sab ntawm lub keeb kwm yav dhau (vim tias nws yog ib qho zas xim), thiab cov qauv yog dawb los yog txawv ntawm cov keeb kwm yav dhau, thiab cov keeb kwm yav dhau yog tsaus, nws tuaj yeem lees paub tias yog cov ntaub ntawv luam tawm.

Ua tib zoo tshuaj xyuas ntawm sab nraub qaum ntawm tus qauv qhia pom cov cim ntawm cov xim keeb kwm yav dhau (qhov no tshwm sim vim tias cov tshuaj tua kab mob tsis tuaj yeem nkag mus rau hauv cov ntaub).

3, anti-dyeing luam ntawv

Ib qho tshuaj lom neeg los yog waxy resin luam tawm ntawm daim ntaub dawb uas tiv thaiv lossis tiv thaiv kev nkag mus ntawm cov xim rau hauv cov ntaub.Lub hom phiaj yog muab lub hauv paus xim uas yuav qhia tawm cov qauv dawb.Nco ntsoov tias qhov tshwm sim yog tib yam li hauv kev luam tawm tawm, txawm li cas los xij txoj kev siv los ua kom tiav qhov txiaj ntsig no yog qhov txawv ntawm kev luam tawm.

Dyeing luam ntawv txoj kev tsis yog dav siv, feem ntau nyob rau hauv keeb kwm yav dhau yuav tsis siv nyob rau hauv cov ntaub ntawv ntawm extraction.Feem ntau dye-pov thawj luam ntawv yog ua los ntawm txoj kev xws li khoom siv tes ua los yog tes luam ntawv (xws li siv quav ciab luam ntawv) es tsis yog nyob rau hauv ntau lawm.

Vim tias cov ntawv luam tawm tawm thiab luam tawm los tiv thaiv dyeing ua rau tib lub tshuab luam ntawv, yog li feem ntau los ntawm qhov muag liab qab feem ntau tsis tuaj yeem txheeb xyuas.

Hlawv tawm luam tawm (Hlawv tawm luam tawm)

Ib daim ntawv rotten yog ib qho qauv uas luam tawm nrog cov tshuaj uas ua rau cov ntaub.Yog li kev sib cuag ntawm cov tshuaj thiab cov ntaub tuaj yeem tsim qhov.Cov npoo ntawm qhov nyob rau hauv tattered prints yeej ib txwm hnav tawm thaum ntxov, yog li cov ntaub muaj kev hnav tsis zoo.

Lwm hom rotten print yog ib daim ntaub ua los ntawm cov xov paj sib xyaw, cov xov paj core-spun, los yog sib xyaw ntawm ob lossis ntau dua fibers.Cov tshuaj tuaj yeem rhuav tshem ib qho fiber ntau (cellulose), ua rau lwm tus tsis zoo.Txoj kev luam ntawv no tuaj yeem tsim ntau cov ntaub ntawv tshwj xeeb thiab nthuav dav.

5, wrinkle shrinkage paj / ua npuas ncauj luam ntawv

Siv cov txheej txheem luam ntawv ntawm cov ntaub ntawm cov ntawv thov hauv zos ntawm cov tshuaj tuaj yeem ua rau cov fiber ntau nthuav lossis kev cog lus, los ntawm kev kho kom zoo, kom cov ntawv luam tawm ntawm cov fiber ntau thiab cov ntawv tsis yog ib feem ntawm cov fiber ntau expansion lossis contraction sib txawv, thiaj li yuav tau txais qhov chaw ntawm qhov tsis tu ncua concave thiab convex qauv ntawm cov khoom.Xws li kev siv caustic soda puffing tus neeg saib xyuas ntawm cov paj rwb ntshiab luam tawm seersucker.Kuj tseem hu ua convex printing.

Lub foaming kub yog feem ntau 110C, lub sij hawm yog 30 vib nas this, thiab lub tshuab luam ntawv yog 80-100 mesh.

6, Txheej luam ntawv (Pigment Printing)

Vim hais tias cov txheej tsis yog dej-soluble colouring khoom, tsis muaj affinity rau cov fiber, nws cov xim yuav tsum tau cia siab rau cov zaj duab xis tsim polymer compound (adhesive) txheej thiab fiber ntau adhesion kom ua tiav.

Txheej cov ntaub ntawv luam tawm tuaj yeem siv rau kev ua cov fiber ntau textiles, thiab muaj qhov zoo dua hauv kev luam ntawv ntawm cov khoom sib xyaw thiab kev sib tshuam, thiab cov txheej txheem yog qhov yooj yim, dav spectrum, paj duab qhia meej meej, tab sis qhov kev xav tsis zoo, lub rubbing. fastness tsis siab.

Xim luam ntawv yog kev luam ntawv ncaj qha ntawm cov xim, uas feem ntau hu ua qhuav luam ntawv kom paub qhov txawv ntawm kev luam ntawv ntub dej (lossis dye printing).

Lawv muaj qhov zoo lossis txawm tias lub teeb nrawm nrawm thiab ziab kom ceev ceev, yog li lawv tau siv dav hauv cov ntaub zoo nkauj, ntaub ntaub thiab khaub ncaws uas yuav tsum tau ntxuav kom qhuav.
