Raws li cov khoom siv tau yooj yim paub txog nws txoj kev nplij siab thiab ntau yam,knitted ntaubtau pom ntau daim ntawv thov hauv khaub ncaws, tsev décor, thiab kev tiv thaiv hnav. Txawm li cas los xij, cov tsoos textile fibers zoo li flammable, tsis muaj softness, thiab muab cov rwb thaiv tsev tsawg, uas txwv tsis pub lawv siv dav. Kev txhim kho cov nplaim hluav taws-resistant thiab xis nyob ntawm textiles tau dhau los ua ib qho tseem ceeb hauv kev lag luam. Nrog rau kev loj hlob tseem ceeb ntawm cov ntaub ntawv ntau yam thiab ntau yam kev zoo nkauj, ob qho tib si kev kawm thiab kev lag luam tau sib zog los tsim cov ntaub ntawv uas ua ke nrog kev nplij siab, nplaim taws, thiab sov so.
Tam sim no, feem ntaunplaim-resistant fabricsyog tsim los ntawm cov nplaim hluav taws-retardant txheej los yog cov txheej txheem sib xyaw. Coated fabrics feem ntau ua nruj, plam nplaim taws tom qab ntxuav, thiab tuaj yeem degrade los ntawm hnav. Meanwhile, composite fabrics, txawm hais tias nplaim-resistant, feem ntau yog thicker thiab breathable, sacrificing kev nplij siab. Piv nrog rau cov ntaub woven, knits yog ib txwm softer thiab xis dua, uas tso cai rau lawv siv los ua ib lub hauv paus txheej los yog cov khaub ncaws sab nrauv. Nplaim-resistant knitted fabrics, tsim siv inherently nplaim-resistant fibers, muab cov nplaim hluav taws tiv thaiv tsis muaj ntxiv tom qab kho thiab khaws lawv txoj kev nplij siab. Txawm li cas los xij, kev tsim cov ntaub ntawv no yog qhov nyuaj thiab kim, vim tias cov nplaim hluav taws kub-resistant fibers zoo li aramid yog kim thiab nyuaj rau kev ua haujlwm nrog.
Cov kev txhim kho tsis ntev los no tau ua raunplaim-resistant woven fabrics, feem ntau yog siv cov xov paj zoo li aramid. Thaum cov ntaub no muab cov nplaim hluav taws zoo heev, lawv feem ntau tsis muaj kev ywj pheej thiab kev nplij siab, tshwj xeeb tshaj yog thaum hnav ntawm daim tawv nqaij. Cov txheej txheem knitting rau nplaim taws-resistant fibers kuj yuav nyuaj; lub siab tawv thiab tensile lub zog ntawm nplaim-resistant fibers ua rau qhov nyuaj ntawm kev tsim cov mos mos thiab xis knitted fabrics. Yog li ntawd, nplaim taws-resistant knit fabrics kuj tsis tshua muaj.
1. Core Knitting txheej txheem tsim
Qhov project no nrhiav kev tsim ibntaubuas integrates nplaim tsis kam, anti-static zog, thiab warmth thaum muab kev nplij siab zoo. Txhawm rau ua tiav cov hom phiaj no, peb tau xaiv cov qauv ua ob sab. Lub hauv paus xov paj yog 11.11 tex nplaim-resistant polyester filament, thaum lub voj xov paj yog sib xyaw ntawm 28.00 tex modacrylic, viscose, thiab aramid (hauv 50: 35: 15 piv). Tom qab kev sim thawj zaug, peb txhais cov ntsiab lus tseem ceeb ntawm knitting, uas tau piav qhia hauv Table 1.
2. Txheej txheem optimization
2.1. Cov teebmeem ntawm Loop Length thiab Sinker Qhov siab ntawm Fabric Properties
Cov nplaim hluav taws xob ntawm antaubnyob ntawm ob qho tib si combustion zog ntawm cov fibers thiab yam xws li ntaub qauv, thickness, thiab cua cov ntsiab lus. Hauv weft-knitted fabrics, kho lub voj ntev thiab qhov siab ntawm lub dab dej (lub voj qhov siab) tuaj yeem cuam tshuam cov nplaim taws thiab sov so. Qhov kev sim no tshuaj xyuas cov txiaj ntsig ntawm qhov sib txawv ntawm cov ntsuas no txhawm rau txhim kho cov nplaim hluav taws xob thiab rwb thaiv tsev.
Kev ntsuas sib txawv ntawm cov voj voog ntev thiab qhov siab ntawm lub dab dej, peb pom tias thaum lub hauv paus xov paj lub voj voog ntev yog 648 cm, thiab qhov siab ntawm lub dab dej yog 2.4 hli, cov ntaub npuag yog 385 g / m², uas tshaj qhov project qhov hnyav lub hom phiaj. Xwb, nrog lub hauv paus xov paj ntev ntawm 698 cm thiab qhov siab ntawm lub dab dej ntawm 2.4 hli, cov ntaub nthuav tawm cov qauv xoob thiab qhov sib txawv ntawm -4.2%, uas poob luv luv ntawm lub hom phiaj specifications. Qhov kev ua kom zoo tshaj plaws no tau ua kom ntseeg tau tias qhov kev xaiv lub voj ntev thiab qhov siab lub dab dej tau txhim kho ob qho tib si nplaim taws thiab sov so.
2.2.Cov teebmeem ntawm FabricKev pab them nqi hluav taws xob tiv thaiv
Cov txheej txheem ntawm cov ntaub tuaj yeem cuam tshuam nws cov nplaim taws, tshwj xeeb tshaj yog thaum cov xov paj yog polyester filaments, uas tuaj yeem tsim cov tee dej thaum hlawv. Yog tias qhov kev pov hwm tsis txaus, cov ntaub yuav ua tsis tau raws li cov qauv kev tiv thaiv hluav taws. Cov khoom muaj feem cuam tshuam nrog suav nrog cov xov paj twist, cov khoom siv xov paj, qhov teeb tsa lub tog raj kheej, rab koob sib txuas, thiab cov ntaub ntim cov ntaub.
Qhov nqa-up nro cuam tshuam cov ntaub npog thiab, yog li, nplaim hluav taws. Take-up nro yog tswj los ntawm kev kho cov iav piv nyob rau hauv lub rub-down mechanism, uas tswj cov xov paj txoj hauj lwm nyob rau hauv lub koob nuv. Los ntawm qhov kev hloov kho no, peb tau ua kom zoo dua cov xov paj npog ntawm lub hauv paus xov paj, txo qhov sib txawv uas tuaj yeem cuam tshuam cov nplaim taws.
3. Kev txhim kho lub tshuab ntxuav
Kev kub ceevncig knitting tshuab, nrog rau lawv cov ntsiab lus pub mis ntau, tsim cov lint thiab hmoov av ntau heev. Yog tias tsis tshem tawm tam sim ntawd, cov kab mob no tuaj yeem cuam tshuam cov ntaub zoo thiab kev ua haujlwm ntawm lub tshuab. Muab hais tias qhov project lub voj voog xov paj yog ib qho kev sib xyaw ntawm 28.00 tex modacrylic, viscose, thiab aramid luv fibers, cov xov paj nyiam ntau dua lint, muaj peev xwm thaiv txoj kev pub noj, ua rau cov xov paj tawg, thiab tsim cov ntaub tsis xws luag. Txhim kho qhov kev tu lub cev rauncig knitting tshuabyog qhov tseem ceeb rau kev tswj kom zoo thiab ua haujlwm zoo.
Thaum cov khoom siv tu ib txwm siv, xws li cov kiv cua thiab cov tshuab cua compressed, muaj txiaj ntsig zoo hauv kev tshem cov lint, lawv yuav tsis txaus rau cov xov paj luv luv, vim lint buildup tuaj yeem ua rau cov xov paj tawg. Raws li pom nyob rau hauv daim duab 2, peb txhim kho cov cua ntws los ntawm kev ua kom cov nozzles los ntawm plaub mus rau yim. Qhov kev teeb tsa tshiab no tshem tawm cov plua plav thiab lint los ntawm cov chaw tseem ceeb, ua rau kev ua haujlwm huv. Cov kev txhim kho tau ua rau peb nce ntxivknitting ceevlos ntawm 14 r / min mus rau 18 r / min, boosting peev xwm ntau lawm.
Los ntawm kev ua kom lub voj voog ntev thiab qhov siab ntawm lub dab dej los txhim kho cov nplaim taws thiab kev sov so, thiab los ntawm kev txhim kho kev pab cuam kom tau raws li cov qauv hluav taws xob tiv thaiv, peb tau ua tiav cov txheej txheem knitting ruaj khov uas txhawb cov khoom xav tau. Cov kev hloov kho tshiab kuj tseem txo cov xov paj tawg vim lint buildup, txhim kho kev ua haujlwm ruaj khov. Kev txhim kho kev tsim khoom nrawm tau tsa lub peev xwm qub los ntawm 28%, txo cov sij hawm ua cov hmoov txhuas thiab nce cov zis.
