Kev tsim ntawm knitted fabrics

1.Ua cov xov paj

Thawj kauj ruam hauv kev ua cov ntaub knitted yog kev tsim cov xov paj, uas yog cov txheej txheem tseem ceeb vim tias qhov zoo ntawm knitted fabrics ncaj qha nyob ntawm cov yarns siv. Cov ntaub ntawv raw ntawm knitted fabrics yog cov xov paj, uas feem ntau yog ua los ntawm ntau yam ntaub ntawv xws li paj rwb ntshiab, polyester, ntaub plaub, txhob lo lo ntxhuav, thiab lwm yam., thiab tau muab sib xyaw rau hauv qhov tsim nyog proportions kom ua tiav qhov zoo tshaj plaws thiab kev ua tau zoo. Piv txwv li, cov xov paj ntshiab ntshiab muaj kev ua pa zoo thiab kev nplij siab, thaum polyester muab kev hnav tsis kam thiab wrinkle tsis kam, ntaub plaub tuaj yeem ua kom sov, thiab txhob lo lo ntxhuav muab cov ntaub zoo nkauj thiab du. Yog li ntawd, xaiv cov ntaub ntawv raw thiab sib tov sib xyaw yog tus yuam sij rau kev ua cov ntaub zoo zoo knitted.

Hauv kev tsim cov xov paj, kev tswj xyuas zoo yog qhov tseem ceeb tshwj xeeb vim tias qhov zoo ntawm cov xov paj ncaj qha cuam tshuam rau qhov zoo thiab kev ua tau zoo ntawm cov khoom kawg. Txhawm rau kom ntseeg tau qhov zoo ntawm cov xov paj, cov txheej txheem tsim khoom yuav tsum mus dhau ntawm cov txheej txheem muag heev. Cov txheej txheem no suav nrog kev xaiv paj rwb, qhib, kos duab, combing, roving thiab spun yarn, thiab lwm yam.

Ua ntej, kev xaiv paj rwb yog xaiv cov paj rwb zoo ntawm cov paj rwb ntau, tshem tawm cov impurities thiab cov paj rwb tsis zoo los xyuas kom meej cov purity ntawm cov ntaub ntawv raw. Tom ntej no, cov txheej txheem qhib siv cov cuab yeej siv tshuab los qhib cov paj rwb fibers thiab ua rau lawv xoob rau kev ua haujlwm tom ntej. Tom qab ntawd, nyob rau hauv cov txheej txheem kev kos duab, ntau cov paj rwb yarns tau ua ke los ua ib qho kev sib xyaw ntawm cov xov paj los txhim kho qhov sib xws thiab lub zog ntawm cov xov paj.

Cov txheej txheem combing siv cov cuab yeej tshwj xeeb combing kom tshem tawm cov fibers luv thiab impurities hauv cov xov paj los txhim kho qhov smoothness thiab lub zog ntawm cov xov paj. Tom qab combing, cov xov paj feem ntau yog muag heev thiab haum rau ua high-end knitted fabrics. Tom qab ntawd, kev tsim cov xov paj thiab spun yarn yog tig cov xov paj combed strips los tsim cov xov paj ntawm cov thicknesses sib txawv kom tau raws li qhov xav tau ntawm cov ntaub sib txawv.

2.Ntaub ntaub

Tom qab cov xov paj tiav lawm, cov kauj ruam tom ntej yog cov ntaub qhwv, uas yog ib kauj ruam tseem ceeb hauv tag nrho cov txheej txheem tsim khoom. Knitting tshuab, raws li cov tub ntxhais txuas ntawm knitted npuag ntau lawm, muaj ntau yam, nrog rau cov xov tooj ntawm knitting koob, knitting tshuab qauv, knitting txoj kev, thiab lwm yam. Cov yam tseem ceeb no tsis tsuas yog cuam tshuam rau ntau lawm efficiency, tab sis kuj ncaj qha ntsig txog qhov zoo, tsos. thiab xav txog cov khoom kawg.

Ua ntej, kev xaiv ntawm knitting koob yuav cuam tshuam qhov ntom thiab thickness ntawm cov ntaub. Cov koob ntau dua, cov ntaub yuav nruj dua feem ntau, thiab qhov xav tau ntau dua yuav zoo; thaum fabrics nrog tsawg koob yuav ua tau ntau breathable thiab haum rau lub caij ntuj sov khaub ncaws xav tau kev pab. Qhov thib ob, cov qauv sib txawv ntawm cov tshuab knitting kuj tseem muaj feem cuam tshuam rau cov yam ntxwv ntawm cov ntaub. Niaj hnub nimno knitting tshuab feem ntau muaj ntau dua precision thiab efficiency, thiab muaj peev xwm tsim ntau complex qauv thiab tsim kom tau raws li lub khw qhov kev thov rau tus kheej thiab ntau haiv neeg.

Tsis tas li ntawd, kev xaiv ntawm txoj kev knitting yog qhov tseem ceeb sib npaug. Cov txheej txheem knitting muaj xws li cov koob tiaj tus, ribbed koob, voj koob, thiab lwm yam, txhua yam uas muab cov ntaub sib txawv elasticity thiab cov tsos mob. Piv txwv li, ribbed knitted fabrics feem ntau muaj elasticity zoo thiab rov qab los ntawm lawv cov qauv tshwj xeeb, uas yog tsim los ua cov khaub ncaws zoo. Loop koob feem ntau siv los ua cov ntaub hnyav dua, haum rau cov khaub ncaws caij ntuj no.

Tom qab weaving, cov ntaub tsis yog cov khoom kawg, tab sis yuav tsum tau mus los ntawm cov txheej txheem tom ntej, xws li immersion, dyeing, thiab lwm yam. Cov txheej txheem no tsis tuaj yeem txhim kho cov xim saturation thiab pom cov nyhuv ntawm cov ntaub, tab sis kuj txhim kho. lub durability thiab kev nplij siab ntawm cov ntaub. Cov txheej txheem immersion tuaj yeem tshem tawm cov impurities hauv cov ntaub thiab ua kom cov purity ntawm cov ntaub, thaum cov txheej txheem dyeing ntxiv cov xim nplua nuj rau cov ntaub, ua rau nws muaj kev sib tw hauv kev ua lag luam.

3.Dyeing thiab ua

Cov txheej txheem dyeing ntawm knitted fabrics yog ib tug complex thiab technically demanding txheej txheem, nrog rau kev xav txog ntau yam. Ua ntej tshaj plaws, kev xaiv dyeing yuav tsum yog raws li qhov sib txawvntaub ntaub. Piv txwv li, paj rwb knitted fabrics feem ntau haum rau dyes ncaj qha, thaum ntuj fibers xws li ntaub plaub los yog txhob lo lo ntxhuav yog ntau haum rau acid dyes. Qhov no yog vim cov xim sib txawv muaj qhov sib txawv nrog cov fibers, thiab xaiv cov xim zoo tuaj yeem ua kom pom qhov zoo tshaj plaws ntawm cov nyhuv dyeing.

Cov txheej txheem dyeing feem ntau suav nrog yaj dyeing thiab ncaj dyeing. Melt dyeing feem ntau yog tsim rau hluavtaws fibers, xws li polyester fibers. Txoj kev no heats cov dye mus rau lub xeev molten thiab tso cai rau nws nkag mus rau hauv lub fiber kom ua tau ib tug uniform dyeing nyhuv. Direct dyeing yog siv cov dye ncaj qha rau ntawm fiber ntau. Nws yog qhov tsim nyog rau qee qhov ntuj fibers thiab tuaj yeem dyed ntawm qhov kub thiab txias, txuag lub zog.

Kev ua dyeing tsis yog tsuas yog txhim kho cov tsos ntawm cov ntaub, tab sis kuj tseem muaj feem cuam tshuam rau cov xim, xim ceev thiab gloss ntawm cov khoom tiav. Xim ceev ceev yog hais txog lub peev xwm ntawm covdyed ntaubtswj nws cov xim nyob rau hauv ib puag ncig sab nraud xws li ntxuav, txhuam thiab lub teeb. Cov xim zoo nkauj tuaj yeem ua kom muaj zog thiab kev zoo nkauj ntawm cov ntaub thaum siv. Tsis tas li ntawd, lub glossiness thaum lub sij hawm dyeing txheej txheem kuj yuav cuam tshuam rau tag nrho cov kev pom ntawm cov ntaub. Fabrics uas muaj zog gloss feem ntau tshwm sim ntau dua thiab txaus nyiam.

Hauv kev ua dyeing, kev xaiv cov dyes yog qhov tseem ceeb. Feem ntau hais lus, cov dyes feem ntau siv hauv kev ua dyeing muaj xws li yaj dyes, ncaj dyes thiab acid dyes. Melt dyes yog tsim rau cov hluavtaws fibers thiab tuaj yeem muab cov xim ci; ncaj dyes yog haum raupaj rwb ntaubs thiab muaj xim zoo; Thaum cov kua qaub dyes feem ntau yog siv rau cov ntaub plaub thiab lo lo ntxhuav, uas tuaj yeem muab cov ntaub nplua nuj xim thiab gloss. Kev xaiv cov xim tshwj xeeb yuav tsum tau ua tiav raws li cov khoom siv ntawm cov ntaub, siv ib puag ncig thiab qhov chaw ntawm cov khoom kawg.

4.Kev huv thiab kev ua haujlwm

Tom qab dyeing, cov ntaub nkag mus rau hauv cov txheej txheem tiav, uas yog ib qho tseem ceeb los xyuas kom meej tias cov ntaub ua tiav cov khoom tiav zoo tshaj plaws. Cov txheej txheem tiav feem ntau suav nrog ntau qhov sib txuas, xws li sizing, dov, ziab thiab calendering, txhua tus ua lub luag haujlwm tseem ceeb hauv qhov kawg qhov zoo thiab cov tsos ntawm cov ntaub.

Ua ntej tshaj plaws, sizing yog thawj kauj ruam hauv kev ua tiav, thiab lub hom phiaj tseem ceeb yog txhawm rau txhim kho qhov rigidity thiab gloss ntawm cov ntaub los ntawm kev ntxiv sizing. Kev xaiv thiab tus nqi ntawm qhov loj me yuav cuam tshuam ncaj qha rau kev xav thiab pom ntawm cov ntaub. Qhov loj me tuaj yeem ua tauua cov ntaubntau nruj, txo wrinkles, thiab txhim khu lub zuag qhia tag nrho cov nyhuv.

Tom ntej no yog cov txheej txheem dov, uas feem ntau yog dov cov ntaub kom huv si rau kev khaws cia thiab kev thauj mus los tom ntej. Thaum lub sij hawm dov txheej txheem, tus neeg teb xov tooj yuav tsum xyuas kom meej qhov flatness ntawm cov ntaub, tsis txhob wrinkles thiab deformation, thiaj li ua kom cov ntaub huv si thiab zoo nkauj.

Kev ziab yog ib qho tseem ceeb hauv kev ua tiav, lub hom phiaj ntawm kev tshem tawm cov dej noo ntawm cov ntaub thiab ua kom nws ruaj khov thiab ruaj khov hauv kev siv tom ntej. Lub ziab kub thiab lub sij hawm yuav tsum tau kho raws licov khoom ntawm cov ntaubtiv thaiv kom tsis txhob kub dhau los ua rau shrinkage lossis puas rau cov ntaub.

Thaum kawg, calendering yog txheej txheem ntawm flattening cov ntaub los ntawm cov khoom siv kho tshuab los txhim kho nws cov gloss thiab xav. Calendering tsis tsuas yog ua rau saum npoo ntawm cov ntaub smoother, tab sis kuj txhim kho nws qhov muag pom kev, ua rau cov ntaub tiav zoo dua.
