Elastic fiber tau nkag mus rau txhua yam ntawm tib neeg lub neej txhua hnub, yog qhov tseem ceeb rau lub neej ntawm cov ntaub ntawv textile thiab khaub ncaws!
Yog tsis muaj nws, tsis muaj hnab looj tes rau cov poj niam zoo nkauj; tsis muaj nws, tsis muaj lub caij ntuj sov muaj yeeb yuj swimsuits; tsis muaj nws, tsis muaj qhov tseem ceeb ntawm dab ntxwg nyoog lub cev ntawm leggings ...... Nws tuaj yeem hais tias elastic fiber ntau rau tib neeg los qhia lub cev, txaus siab rau kev nplij siab ntawm hnav khaub ncaws tau ua rau muaj txiaj ntsig zoo!
Hais txog elastic fibers, peb yuav tsum tau hais txog xyoo 1962 US DuPont ntau lawm ntawm spandex. Tsis zoo li lwm cov hluavtaws fibers, spandex yog ib qho tshwj xeeb fiber ntau nrog cov roj hmab zoo li stretch zog. Spandex fibers tau siv nyob rau hauv ntau hom kev ua kis las, los ntawm cov thom khwm elastic thiab pantyhose mus rau cov khaub ncaws ua luam dej thiab cov ris tsho, thiab tom qab ntawd mus rau cov ris tsho hauv qab xws li cov ris tsho hauv qab nruj, petticoats, thiab blouses, uas xav tau qib siab ntawm kev zoo nkauj thiab kev nplij siab. Tsis ntev los no, vim nws hnav kev nplij siab thiab kev tsim kho kom haum, tab sis kuj tau siv sai heev rau cov tsho, sib xyaw cov khaub ncaws ntawm ntau yam fibers, knitted outerwear thiab lwm cov ntaub ntawv qib siab thiab cov khaub ncaws qib siab.
Cov yam ntxwv tseem ceeb ntawm spandex ntaub
1. spandex elasticity yog siab heev, cov khoom siv dav dav tsis siv 100% polyurethane, ntau dua hauv cov ntaub sib xyaw nrog qhov sib piv ntawm 5-30%, qhov tshwm sim ntau yam ntawm spandex fabrics muaj 15% mus rau 45% ntawm kev nplij siab ntawm elasticity. .
2. spandex feem ntau tsis yog siv ib leeg xwb, spandex fabrics feem ntau yog ua los ntawm cov xov paj sib xyaw, xws li spandex li cov tub ntxhais, nrog rau lwm cov fibers (xws li nylon, polyester, thiab lwm yam) ua rau cov tawv nqaij ua los ntawm cov core yarn stretch fabrics, nws adaptability rau lub cev yog zoo, heev haum rau ua tights, tsis muaj siab.
3. Cov qauv zoo nkauj thiab kev ua haujlwm ntawm spandex stretch fabric yog ze rau cov khoom zoo sib xws ntawm cov ntaub npog sab nrauv.
Nyob rau hauv cov txheej txheem dyeing thiab xov ntawm spandex, yog tias cov txheej txheem tsis zoo, nws yuav ua rau muaj teeb meem xws li poob elasticity thiab wrinkle. Yog li ntawd, dyeing thiab xov ntawm spandex yuav tsum yog nyob rau hauv ob qhov teeb meem loj, thiab cov txheej txheem yuav tsum tau kho kom haum raws li cov kev cai ntawm cov neeg muas zaub.
Txij li thaum spandex txhawm rau txhawm rau txhim kho kev khiav haujlwm hauv kev sib tw, hauv cov txheej txheem siv cov roj silicone roj thiab lwm yam khoom ntxiv. Cov additives no yuav ib txwm degrade nyob rau lub sij hawm uas ua rau yellowing ntawm cov fibers thiab ib tug txo nyob rau hauv lub elasticity ntawm ntaub. Nyob rau tib lub sij hawm, spandex-muaj fabrics nyob rau hauv lub sij hawm ntev cia yuav tsim ib tug "txias txheej", yog li ntawd cov ntaub nyob rau hauv lub post-processing ntawm mus tas li wrinkles yuav tsis raug tshem tawm. Yog li ntawd, spandex-muaj knitted fabrics, ntxiv rau txo lub sij hawm cia, nws yog ib qho tseem ceeb dua rau weave tam sim ntawd tom qab qhib lub tiaj tus dav ntawm yob kom tsis txhob muaj lub sij hawm los tsim lub siab crease.
Spandex-muaj knitted fabrics, lub spandex nyob rau hauv lub fiber tom qab lub tshuab, muaj ib tug npaum li cas ntawm cov kev ntxhov siab nyob rau hauv tsim thaum lub sij hawm weaving. Yog li ntawd, lub hom phiaj ntawm preheating thiab shaping yog kom tshem tawm cov kev ntxhov siab los ntawm cov ntaub ib daim ntawv txheej txheem, thiaj li hais tias cov ntaub qhov ntev yog tag nrho stabilized, tshem tawm cov ntaub nyob rau hauv lub post-processing ntawm mus tas li creases. Yog hais tias lub kauj thib ob yog rau sab laug ntawm thawj zaug hauv cov ntaub ntawv ntawm cov loops tsim thaum lub tog raj kheej weaving, ces cov kev taw qhia ntawm pub yuav tsum yog 7% mus rau 10% (xws li qhov dav) nyob rau hauv pem hauv ntej ntawm sab laug sab thaum lub sij hawm pre-shaping. , kom qhov twist yog raws li cov khoom tiav.
Pre-forming
Yog li ntawd, qhov zoo tshaj plaws pre-shaping program yog:
Relaxation → chav chav (tsis muaj chav dej ntawm dov dej kub 80 degree) → super pub pre-shaped → (rau hauv cov ntaub pretreatment → shaping → printing).
Feem ntau ntawm cov dyeing cog vim tias tsis muaj cov cuab yeej siv thiab cov dej ntws ncaj qha mus rau hauv qhov chaw, thaum qhov kub thiab txias qis dua 10 degrees (lub caij ntuj no), cov ntaub yog qhov yooj yim rau creases. Npuag los ntawm lub thawv chav tsev so thiab tom qab ntawd shaping, yuav tau txais txiaj ntsig zoo. Thermal shaping kub rau l85 ~ 190 degree yog zoo, shaping lub sij hawm 45 ~ 60 S. Shaping kub siab dhau lawm, yuav ua rau cov ntaub yellowing.
Nyob rau tib lub sij hawm yog hais tias cov ntaub impurities thiab additives vim muaj kev cuam tshuam ntawm ci thiab ib nrab degradation, nws degradation ntawm cov khoom ib zaug migrated mus rau sab hauv ntawm lub fiber los tsim cov cim, ces cov cim nyob rau hauv lub tom kawg ua yog nyuaj rau tshem tawm, dyeing ntawm. fiber ntau nyob rau hauv cov roj chaw yuav yog thawj zaug nqus cov dyeing, thiab nyob rau hauv lub tshav kub preservation hloov dyeing txheej txheem thiab tsis muaj peev xwm khiav tawm ntawm cov txheej txheem raws sij hawm thiab tsim dyeing qhov tob qhov chaw, txawm tias tom qab stripping. Cov xim ntawm cov dyeing dua, nws tseem yuav seem nyob rau hauv cov ntaub, yog li ntawd, tsis txhob kub siab shaping saum 195 degree (Platform Jun Note: lub softening kub ntawm spandex yog siab dua 200 degree), uas yuav kuj cuam tshuam qhov ceev ntawm spandex. Qhov dav ntawm qhov shaping yog dav dua li ntawm cov ntaub dawb paug los ntawm l0% mus rau l5%, yog li nws tuaj yeem muaj kev rov zoo tag nrho hauv cov dyeing vat thaum lub sij hawm ua ntej, kom qhov kev ntxhov siab sab hauv ntawm cov ntaub tuaj yeem tshem tawm tag nrho.
Kev kho mob ua ntej
Yuav tsum tau luam tawm cov ntaub knitted kuj yuav tsum tau kho ua ntej, tshem tawm cov paj rwb impurities thiab roj ciab, ua kom cov ntaub dawb thiab txhim kho cov ntaub ntub dej, nqus dej, kom ua tiav cov txiaj ntsig zoo. Cov txheej txheem ua ntej kev kho mob tuaj yeem muab faib ua ob pawg, uas yog, kev kho ib txwm muaj alkali thiab niaj hnub kev kho mob bio-enzyme, kev kho bio-enzyme raws li qhov yuav tsum tau ua ntawm kev tiv thaiv ib puag ncig, tab sis tam sim no nws nyuaj ua kom tau raws li qhov yuav tsum tau ua kom dawb huv. los yog bleaching yuav tsum tau ntawm high fabrics, yog li cov pa alkali kev kho cov txheej txheem yog tseem lug siv, spandex-muaj fabrics ua ntej kev kho mob ntawm gradual txias ntawm cov txheej txheem ntxuav yog heev tsim nyog los tiv thaiv cov fiber los ntawm shrinking los ntawm lub tam sim ntawd txias ua creases.
Semi-product shaping xav tau
Semi-cov khoom ntawm cov duab, yuav tsum tau ua raws li tus txheej txheem tsim qauv, feem ntau hais lus, cov duab ntawm qhov dav ntawm qhov dav ntawm cov khoom tiav yog dav dua 3% mus rau 5% los yog li ntawd, cov warp shrinkage tswj hauv cov khoom tiav. nyob rau hauv qhov yuav tsum tau shrinkage, lub elongation ntawm daim ntaub yog sib npaug zos rau tracing ntawm qhov loj piv. Yog hais tias nws yog ib leeg-sided knitted ntaub, ces koj kuj yuav tsum tau paddle txiav ntug thiab qhov zoo tshaj plaws twist tswj, kom txo tau cov luam tawm weft skew vim twist. Qhov dav ntawm qhov sizing ntug yog hais txog lcm, nrog rau qhov tawg taw tes qhov loj me. Yuav tsum tsis txhob nyias los yog tuab heev, nyias nyias los ua lub luag haujlwm, tuab heev yuav cuam tshuam rau cov nyhuv ntawm luam ntawv ze ntawm ntug ntawm daim ntaub. Txheej luam ntawv vim nyob rau hauv daim ntaub nto ntawm cov tawv nqaij yuav kuj nce square meter grams ntaub zoo, yog li nyob rau hauv dav, shrinkage tus nqi nyob rau hauv txoj kab nrog rau tej yam kev mob, lub grams ntawm zoo yuav ua tau me ntsis sib zog.
