Ua Ntej Soj Ntsuam Rau Cov Qauv Uas Txawv Tua Tsiaj Me
Lub suede yog tsim los ntawm hiav txwv-kob hom ultra-nplua polyester yarn, uas yog ces desizing, scouring, slackening, pre-tsim fiber ntau qhib, zom thiab dyeing kom tau suede ntaub nrog mos mos thiab zoo drape. Elegant; tus tes taw tes, lub suab muag, lub zog, kev sau ntawv zoo "; qhov yoojyim zoo, kev ruaj nplej, kev hnav zoo; tsis tshua muaj zog ntawm monofilament, tab sis kuj muaj zog, nyhav Tag nrho lub zog muaj peev xwm ua tau raws li kev siv thiab hnav ua haujlwm zoo. Tsis tas li ntawd, nws muaj cov yam ntxwv ntawm kev ruaj ntseg ntawm qhov ntev thiab kev yoo mov uas tshwm sim rau cov tshuaj fiber ntau ntawm cov tshuaj. Yog li no, suede cov khoom yog favored los ntawm cov kev pab. Tus yuam sij rau kev zoo nkauj ntawm suede fabrics yog dyeing thiab xov ntawm fabrics, uas pretreatment yog tshwj xeeb tseem ceeb.
Lub hom phiaj ntawm cov txheej txheem ua ntej yog ua rau: 1) ntxuav cov roj ntawm daim ntaub ntawm daim ntaub xim kom tiv thaiv cov xim thiab cuam tshuam tag tom qab dyeing; 2) ua rau cov hom kob hom polyester microfiber fiber qhib thiab txo, uas yog yooj yim rau tom qab sib tsoo Thiab ua rau cov ntaub muaj zoo drapability thiab hnov; 3) ua kom cov ntaub npog tag nrho, kom lub ntsej muag yog tuab, nrog rau qhov "sau nyhuv", tag nrho rov qab txog qhov khoom style.
1.1 Ntxhais kub thiab NaOH cov concentration rau qhov yuav txo qis Thaum tib lub kub tuav, raws li NaOH huab hwm coj concentration nce, txo tus nqi nce. Qhov no yog vim tias qhov ntau dua qhov concentration of NaOH, qhov siab zog ntawm kev sib txuas ntawm cov fiber ntau thiab cov caustic soda, thiab qhov nce ntxiv ntawm OH-tua cov nyiaj ester, yog li qhov txo nqi nce. Tib lub sij hawm, ntawm tib lub NaOH huab hwm coj concentration, txo tus nqi nce nrog kev nce ntawm qhov tuav txias. Yog vim li cas lub ntsiab lus tseem ceeb: Thawj zaug, lub tshuab raj alkali ntawm polyester yog txheej txheem ob-diffusion cov tshuaj tiv thaiv, uas yog, cov reactants nyob rau hauv cov tshuaj tawg mus rau qhov chaw siv fiber ntau, thaj tsam amorphous, thiab ntug ntawm qhov chaw tua crystallization, thiab hydrolyzed khoom diffuses los ntawm cov fibre rau cov tshuaj, qhov kub nce, thiab ob lub diffusion Lub coefficient nce, qhov sib npaug ntawm ob lub zog nce, thiab txo tus nqi nce. Secondly, dawb lub tswv yim theory qhia tau hais tias qhov kub nce, qhov dawb ntim feem ntawm polyester nce, uas yog, qhov chaw seem ntawm lub nce nce, thiab tus naj npawb ntawm active units ntawm fiber ntau molecular saw nce. Thaum cov ciaj ciam txo, cov zaus ntawm cov tshuaj tiv thaiv carbonyl-OH tiv thaiv tuaj yeem nce, thiab qhov txo tus nqi kuj nce ntxiv, yog li qhov nce ntawm qhov kub yog qhov zoo rau qhov tshwm sim ntawm cov roj alkali hydrolysis tshuaj tiv thaiv.
1.2 Feem ntau ntawm cov dej kub thiab NaOH cov ntsiab lus ntawm cov ntaub qhwv lub cev Cov kev nce ntawm NaOH huab hwm coj concentration, cov hluav taws xob thiab cov nyhuv shrinkage ntawm npuag nce, tab sis nrog ntxiv zuj zus ntawm concentration, cov degree ntawm shrinkage tsub kom; raws li qhov kub nce, cov ntaub Lub latitude thiab qhov ntev qhov ntswg qhov nce kuj nce, tab sis raws li qhov kub nce ntxiv, qhov kev kawm ntawm nce hauv shrinkage decreases. Qhov laj thawj tseem ceeb rau qhov hloov ntawm cov hlab ntim tshuaj ntawm cov ntaub tuaj yeem yog tias cov huab hwm coj concentration ntawm NaOH tsub kom, qhov kub nce, cov ntaub npawm txo qhov nce, thiab qhov chaw rau siab shrinkage filaments tsub kom, thiab qhov kawg shrinkage npaum li cas . Qhov loj, tab sis raws li cov concentration thiab kub ntxiv nce, qhov qis qhov nqi nce mus txog qhov siab tshaj plaws, yog li qhov degree nce hauv shrinkage zuj zus. Lwm qhov laj thawj rau qhov kev nce ntawm cov ntaub ntuag yog tias lub siab shrinkage cov iav muaj ib qho uas tsis tshua muaj crystallinity, thiab qhov siab dua qhov kub, qhov me me yog qhov yuam cai rau qhov txav ntawm lub tsho ntawm lub tshuab macromolecular, thiaj li tias cov xibfwb txawj ntse nyob hauv amorphous cheeb tsam ntau dua yooj yim dissociated, ua li no Tus loj dua qhov kev txav ntawm lub tshuab fiber ntau.
1.3 Qhov laj thawj rau qhov sib txawv ntawm qhov khoob khaus thiab lub plob nyom ntawm lub npuag Qhov khoob khoob khawm ntswg muaj ntau dua li latitudinal shrinkage tus nqi, uas yog li ntawm 2.1 npaug ntawm qhov latitude shrinkage feem. Qhov no yog txiav txim los ntawm hom kob hom kabmob siv. Tom qab qhib qhov multifilament, nws kuj muaj cov ntxhib fibers, uas yog cov kua ntsws cov kabmob hauv lub plhaws loj. Lub siab shrinkage polyester fiber muaj cov yam ntxwv ntawm cov khoom siv lead ua qis thiab cov kev taw qhia ntawm cov qauv supramolecular siab. Thaum muaj qhov kub thiab txias, vim tias nws tsis tshua muaj pob zeb nyob hauv, qhov sib zog ua rau lub zog ntawm cov chaw macromolecular me me, yog li ntawd, cov xibfwb qhia qis hauv lub cheeb tsam amorphous yog cov kev taw qhia, uas ua tau cov zaub mov qaub ncaug. Cov kabmob cov kabmob feem ntau yog siv nrog kev sib txoos zoo li lub hnab ntim kom txaus thaum lub sijhawm dyeing thiab xov txheej, yog li xav txog qhov style ntawm qhov khoom.
1.4 Cov nyhuv ntawm kev kho mob rau lub sijhawm txo tus nqi Thaum lub suede npuag kho nrog alkali txo, thaum lub concentration thiab qhov kub yog txiav txim siab, lub sijhawm yog qhov kev txiav txim siab rau kev tswj cov nqi txo. Raws li kev ncua sij hawm ncua sij hawm ntxiv, qhov txo qhov nqi nce, tab sis thaum lub sij hawm nce mus rau ib qho nqi (20 min), qhov txo nqi nce qis. Qhov no yog vim hais tias raws li kev kho mob lub sij hawm nce, qhov tshuaj tiv thaiv ntawm NaOH thiab polyester yog ntau txaus, thiab kev siv tus nqi ntawm NaOH yog qhov nce ntxiv, yog li yuav txo tus nqi ntxiv. Tib lub sij hawm, qhov tshuaj tiv thaiv hydrolysis yog los ntawm qhov txo cov OH-concentration hauv lub cev raws li cov tshuaj tiv thaiv. Qhov ceev ceev qeeb thiab qhov tshwm sim nyhav tom qab ib lub sijhawm twg.
1.5 Cov nyhuv ntawm qhov txo cov ntaub ntawm cov ntaub ntawv Cov ntaub ntawv tsis zoo hauv polyester, raws li qhov txo qhov nqi nce, qhov warp thiab kev nyiag khoov siab nruj, txhuam cov zog thiab tuab yuav tsum maj mam txo, thiab cov roj permeability maj mam ntxiv. Qhov laj thawj yog vim li cas qhov kev ua tiav ntawm suede npuag hloov nrog qhov txo nqi yog txawv ntawm qhov zoo tib yam polyester npuag tsuas yog vim cov xov hlau ntawm lub suede ntaub yog tsim los ntawm lub khob txaj ntawm cov kab xev kab thiab lub siab ntsws cov siab. Qhov txo yuav txo txoj kev sib tw, kev sib zog ua kom muaj zog thiab tuab, thiab cov pa permeability nce ntxiv, thaum lub ntsws ntawm cov xov hlau txav ua rau cov khoom siv no hloov cov lus qhia. Qhov txawv txav ntawm kev hloov yog qhov tshwm sim ntawm qhov kev hloov hauv kev ua vim yog qhov sib quas ntawm cov ntxhuav sib xyaw. Rau cov qauv me me suede fabrics, cov ntaub ntawv yog zoo dua thaum tus nqi yuav txo yog nyob rau hauv qhov ntau ntawm 18.9% mus rau 21.76%.

1) Thaum tib lub kub tuav, nrog rau kev nce ntawm NaOH huab hwm coj concentration, txo tus nqi nce; thaum tib NaOH huab hwm coj concentration, txo tus nqi nce nrog kev nce ntawm qhov tuav txias.
2) Nrog rau kev nce ntawm NaOH huab hwm coj concentration, lub warp shrinkage tus nqi ntawm suede npuag nce, tab sis nrog ntxiv ntxiv ntawm cov concentration, qhov degree ntawm nce ntawm shrinkage tus nqi me dua; raws li qhov kub nce, qhov warp ntawm suede ntaub Tus nqi ntawm shrinkage kuj nce, tab sis raws li qhov kub nce ntxiv.
