Cov tshuab thev naus laus zis ntawm cov ntaub paug tawm
Kev xa xov tawm hluav taws xob tseem hu ua engraving. Hais txog txheej txheem luam ntawv ntawm cov ntaub dyed los ntawm luam tawm xim xim uas tuaj yeem tshem tawm cov "hauv av xim" thiab tsim cov qauv dawb lossis xim. Kev luam tawm, cov xim muab tshuaj uas muaj cov xim tsis zoo yog luam tawm ntawm daim ntaub hauv av, thiab tom qab ziab, nws tau luam tawm nrog cov paj zas xim uas muaj cov tshuaj tiv thaiv lossis cov neeg ua haujlwm tawm. Hauv kev kho mob tom qab, lub zas xim ntawm qhov chaw luam ntawv tau rhuav tshem thiab txiav txim siab, tsim cov qauv dawb ntawm cov xim av lossis cov qauv xim tsim los ntawm kev zas xim xim, uas tseem hu ua xim teeb duab lossis xim kos duab. Vim cov qauv piav ntxaws dua thiab tiag tiag ntawm kev zas xim thiab luam ntawv, tus qauv muaj ntau txheej txheej, qhov sib txawv xim muaj zog, cov qauv qhia ua kom pom tseeb, thiab cov xim tau puv thiab ntau thiab ntau tus neeg tau mloog nws. Nws siv tus neeg sawv cev txo qis thiab tus neeg sawv cev oxidizing kom rhuav tshem cov xim hauv av ntawm cov xim dawb kom tau txais qee qhov ntawm cov xim los yog xim. Cov kuab paug tso tawm los siv sib txawv ntawm cov ntaub mus rau ntaub. Kev tso pa tawm tuaj yeem siv rau ob qho tib si daim ntaub thiab cov ris tsho ua tiav.
1, xim muab tshuaj txhuam kev hloov kho
Qhov muab tshuaj txhuam thiab zas xim tau muab sib xyaw kom zoo, thiab tom qab pom, cov ntawv lim dej ua tiav tau ntxiv. Txawm li cas los xij, nws yuav tsum raug sau tseg tias kev ua cov tin thiab cov zas xim tsis tuaj yeem do tib lub sijhawm, txwv tsis pub cov zas xim kom tsis yooj yim kom yaj, uas yuav ua rau muaj qhov tshwm sim ntawm thaiv cov qhov net, xim taw tes, thiab ntsaws thaum luam ntawv, thaum npaj lub dyeing ntawm dawb pulp lossis lub teeb xim. Txhawm rau ntxiv cov nqi tsim nyog ntawm xiav, cov ntawv ua tiav yuav tsum tau muab sib tov thiab lim ua ntej siv; tus nqi ntawm cov hmoov av yuav tsum tau ua raws li tus qauv yog me me, thiab yog tias tus nqi tsawg, tus qauv yog qhov muag plooj thiab cov qauv tsis meej.
2, tswj qhov kub thiab txias
Qhov kub ntawm lub tshuab luam ntawv tshuab chav ua kom qhuav yuav tsum tsis txhob siab tshaj 100 ° C nyob rau hauv ib txwm mob. Nws yog qhov zoo dua kom qhuav ntawm qhov kub tsawg thiab qhov ntsuas kub kom qhuav dhau dhau lawm kom txo cov paug tawm ntawm kev ua haujlwm ntawm tin. Cov xim zas hauv qab yuav tsum tsis pub ntev tshaj 120 ° C, qhov hauv qab tsis tsum yuav tsum tsis txhob siab tshaj 100 ° C, qhov kub kom qhuav yog qhov tsim nyog, thiab nws yuav tsum tsis txhob tso tseg thaum lub sij hawm ziab. Ua cov tin ua kom zoo rau cov tshuaj ntsuam thiab cov cuab yeej. Raws li ib txwm muaj xwm txheej, cov khoom lag luam yog 5,000 meters. Nws yog ib qho tsim nyog yuav tsum tau kuaj lub vijtsam tiv thaiv cov av paim tawm thiab cov kab tsis huv. Lub siab hloov kho ntawm scraper ntawm lub tshuab luam ntawv yuav tsum zoo ib yam, thiab nws yog qhov tsim nyog los ua qhov hloov zoo. Cov tshuaj ntxuav hniav dawb los yog hluavtaws gelatin feem ntau yog siv rau cov tshuaj pleev xim rau, thiab cov cuab yeej stripping yog qhov phem dua li ntawm sodium alginate. Yog li, nws yog qhov zoo dua los siv hlua-siv tshuab ntxhua khaub ncaws thiab ntxiv dag zog rau kev txo qis thiab ntxuav kom ua rau daim ntaub saum npoo tshiab, xim xim ntshiab, thiab cov paj zoo li meej. Cov.
Cov kev tawm tsam los tiv thaiv ntawm polyester ntaub tuaj yeem faib ua alkali extraction thiab tin tshem tawm, tab sis cov nyhuv ntawm kev ua cov lej ntawm polyester silk ntaub zoo dua. Vim tias cov hmoov av ua tiav tau hloov kho stannous chloride, nws cov insoluble hauv dej tsis yooj yim oxidized los ntawm huab cua, uas nce qhov kev ruaj khov ntawm cov xim lo, thiaj li txhim kho qhov zoo ntawm cov luam ntawv.
Kev cuam tshuam los tiv thaiv luam tawm ntawm daim ntaub paj rwb: Nws tuaj yeem pleev xim nrog cov xim tsis zoo, tuaj yeem pleev xim nrog vinyl sulfone-based reactive black dye, ziab thiab luam tawm, thiab luam tawm nrog ntub txheej luam ntawv txheej txheem. )). Lub hauv paus xim (xim dub) yog xim los ntawm cov txheej txheem dov, thiab cov zas xim tsis yooj yim kho. Overprinting rau tom qab dub dub unfixed, ziab, ncu, thiab tib lub xim txhim kho, cov keeb kwm yav dhau los tau yooj yim hloov mus rau theem xim dub.
Ua paug thiab luam tawm ntawm cov ntaub lo lo ntxhuav thiab ntaub plaub: Cov xim hauv av tuaj yeem pleev nrog cov kua qaub ua kom zoo nkauj thiab cov kua nyeem nti nrog cov qauv azo. Cov xim hauv av ntawm polyester thiab acetate textiles tuaj yeem raug zas nrog disperse dyes nrog azo qauv, thiab tus neeg saib xyuas paug feem ntau muaj zog. Txo tus neeg sawv cev, feem ntau siv stanous oxide, paug luam tawm yog tsuas yog siv rau kev sib sib zog nqus av luam ntawv, luam ntawv nyhuv yog qhov zoo.
