Thaum lub sijhawm tsim khoom, khaws cia, kev thauj mus los, thiab txawm tias hnav thiab saib xyuas cov ntaub ntawv txhua hnub, ntau cov ntaub tsim "ntoo mus tas li"- cov quav tawv tawv uas nyuaj rau du thiab tsis tuaj yeem tshem tawm txawm tias cov txheej txheem ironing. Cov creases no tsis tsuas yog txo qis tag nrho cov kev ntxhib los mos ntawm cov ntaub nto, tab sis, thaum cov khoom tsim los rau hauv cov khaub ncaws, kuj ua rau cov khoom tiav cov tsos thiab kev ncaj ncees. Ntau tus tub lag luam textiles, cov tuam txhab tsim khaub ncaws, thiab cov neeg siv khoom feem ntau xav tsis thoob: yuav ua li cas raws nraim cov ntaub ntawv no, thiab puas muaj cov tswv yim, siv tau los daws lawv? Hauv qab no, peb muab cov lus piav qhia dav dav.
Cias muab tso, ib tug mus tas li crease nyob rau hauv ntaub tshwm sim thaum lub fiber qauv ntawm ib tug quav kab ua "teeb" los yog rigidified, poob nws lub ntuj elastic rov muaj peev xwm. Qhov no hauv paus distinguishes nws los ntawm qhov zoo tib yam, ib ntus wrinkles. Kev taug qab qhov teeb meem rov qab mus rau nws qhov chaw- theem tsim khoom- cov txheej txheem dyeing thiab tiav yog ib qho kev pheej hmoo siab rau kev tsim cov creases mus tas li. Thaum cov ntaub khiav los ntawm cov tshuab xws li hlua-dyeing lossis overflow-dyeing khoom, nws tseem nyob rau hauv ib lub tais, compressed lub sij hawm ntev. Ua ke nrog lub siab - qhov kub thiab txias, qhov chaw ntub dej ntawm cov txheej txheem no, cov saw hlau molecular hauv cov fibers tau hloov kho dua tshiab thiab ua kom nruj. Yog hais tias cov ntaub tsis tau qhib tam sim ntawd thiab flattened tam sim ntawd tom qab raug tshem tawm ntawm lub dyeing vat-los yog yog tias nws yog sab laug stacked thiab nyob ruaj ruaj rau ntev heev- cov thawj mos folds yuav ncaj qha hloov mus rau hauv lub creases mus tas li. Tsis tas li ntawd, kev tswj tsis tau zoo thaum lub sijhawm txheej txheej txheej txheej txheej txheej ntaub- xws li daim ntawv thov tsis sib xws los yog qhov kev tso tseg ntawm qhov ua ntej - teeb tsa theem- tuaj yeem ua rau muaj kev pheej hmoo ntawm kev tsim cov creases mus tas li. Cov ntaub uas muaj qhov tsis zoo ntawm cov qauv kev ruaj ntseg-xws li cov ntaub npuag sib sib zog nqus lossis cov ntaub ntawv xoob xoob xoob xoob{19}}yog qhov tshwj xeeb rau cov teeb meem no.
Lub sijhawm khaws cia thiab logistics tseem ua haujlwm tseem ceeb. Thaum cov ntaub rolls yog stacked siab nyob rau hauv cia, los yog thaum lawv nyob rau hauv lub compression thiab hloov uas txuam nrog ntev - kev thauj mus los, cov kab folds yuav raug rau lub sij hawm ntev gravitational siab. Yog tias qhov no tshwm sim hauv qhov chaw cia qhuav, cov fibers poob noo noo thiab ua nruj; Yog li ntawd, lawv cov elastic rov ua haujlwm poob qis, thaum kawg ua rau cov creases ruaj khov uas tsis tuaj yeem ua tus kheej - kho raws sijhawm. Tshaj li cov khoom siv sab nraud, cov khoom siv hauv lub cev ntawm cov ntaub nws tus kheej ua lub luag haujlwm tseem ceeb. Ntuj fibers thiab regenerated cellulose fibers -xws li paj rwb, rayon, thiab lyocell- pom muaj zog nqus noo noo thiab shrinkage yam ntxwv; Yog tias folded thaum ntub, lawv qhov tsis sib xws tom qab shrinkage thaum ziab tuaj yeem yooj yim "xauv hauv" lub crease. Tsis tas li ntawd, qee qhov sib xyaw hluavtaws nrog cov ntaub qhwv tsis tshua muaj peev xwm yuav tsis muaj kev tiv thaiv txaus rau compression thiab deformation, ua rau lawv sib npaug rau kev tsim cov creases mus tas li. Hauv kev hnav khaub ncaws niaj hnub, cov cwj pwm tsis zoo-xws li khaws cov tsoos tsho rau lub sijhawm ntev, tso cai rau lawv tangle thiab knot thaum lub tshuab ntxhua khaub ncaws, ua rau lawv piled thiab stifled tom qab spin{11}} ziab, los yog ua rau lawv mus rau tshav ntuj kub thiab kub heev uas "sets" creases {{12} mus rau hauv ib tug creases, maj mam ua.
Hmoov zoo, muaj cov txheej txheem tsim los kho-thiab txawm tias kho tag nrho- cov ntaub uas twb tau tsim cov creases tas li. Hauv kev teeb tsa hauv tsev, cov creases me tuaj yeem kho tau siv txoj kev "steam rehydration": sib npaug zos qhov chaw nrog dej, lossis dai khaub ncaws hauv chav dej - puv chav. Los ntawm kev cia siab rau ntawm cov ntaub ntawm nws tus kheej drape thiab lub ntiajteb txawj nqus, nws yuav ib txwm rehydrate thiab so; Tom qab zaum ib pliag, cov creases yuav pom tseeb ploj mus. Tsis tas li ntawd, ib lub tsho hnav khaub ncaws hnav tuaj yeem siv los ua cov ntaub ntawm qhov chaw ruaj khov, ua raws li cov kev taw qhia ntawm lub weave (warp thiab weft). Qhov siab - qhov kub thiab txias yuav pab ua kom cov fibers soften; Txawm li cas los xij, nruj me ntsis txwv tsis pub ncaj qha, siab - cua sov kom qhuav ironing, vim qhov no tuaj yeem ua rau "glazing" (ci ntsa iab me ntsis) lossis scorch cov ntaub nto.
Rau qhov sib sib zog nqus, tawv tawv, ib qho "ntub-tshav kub thiab qhov chaw siab" yog pom zoo: tom qab softening cov ntaub nrog chav ironing, tam sim ntawd tso ib tug ca, hnyav khoom nyob rau hauv lub creased cheeb tsam thaum nws tseem sov. Cia nws txias ib txwm teeb tsa cov duab, yog li ua kom cov fibers nyob rau hauv lub xeev flattened. Rau elastic knit fabrics, cov txheej txheem no tuaj yeem pab tau los ntawm maj mam ncab cov khoom raws nws cov lus qhia warp thiab weft los pab cov xov paj thiab cov xov rov qab mus rau lawv qhov qub. Siv cov ntaub softeners los yog anti-wrinkle conditioning agents ua ke nrog cov kev no tuaj yeem txhim kho fiber ntau smoothness thiab txhim kho cov ntaub elastic rov qab. Yog tias lub Hoobkas- nplai batch ntawm cov ntaub nthuav dav dav dav, qhov kev kho thib ob tuaj yeem ua tiav siv cov txheej txheem xws li re-stenering (dav teeb) lossis tiaj - dav, so kom qhuav. Los ntawm kev koom ua ke tshwj xeeb dyeing thiab xov auxiliaries los muab ib tug du, anti{10}}wrinkle tiav, qhov kev pheej hmoo ntawm cov creases mus tas li yuav raug tshem tawm tau zoo ntawm cov txheej txheem tsim khoom.
Txhawm rau tiv thaiv kom tsis txhob muaj qhov tawg mus tas li, kev mob siab rau kev saib xyuas txhua hnub thiab kev tswj hwm yog qhov tseem ceeb. Thaum khaws cov ntaub bolts, ua qhov tseem ceeb ntawm lub tiaj tiaj, xoob stacking es tsis ua rau lawv lub sijhawm ntev, hnyav hnyav. Thaum ntxhua khaub ncaws, muab tso rau hauv ib lub hnab ntxhua khaub ncaws kom tsis txhob tangling, thiab tam sim ntawd smooth lawv tawm thiab dai lawv kom qhuav tom qab lub voj voog ntxuav tiav. Rau kev khaws cia khaub ncaws, muab qhov tseem ceeb rau dai thaum twg los tau; Yog tias tsim nyog folding, tso ib daim ntaub mos muag raws li cov kab folding kom faib cov siab hauv zos, yog li txo qis qhov tshwm sim ntawm kev tsim cov creases mus tas li.
