Woven Fabric yog dab tsi? Dab tsi yog Knitted Fabric? Cov yam ntxwv thiab qhov sib txawv ntawm ob yog dab tsi?
Peb tau qhia yav dhau los tias cov ntaub ntawv textile tau muab faib ua peb pawg raws li kev ua haujlwm sib txawv: woven fabrics, knitted fabrics, thiab non-woven fabrics. Non-woven fabrics yog tsim los ntawm kev sib txuas los yog stitching xoob fibers. Cov duab taw tes yog zoo li peb daim ntawv tso quav tso quav, uas yooj yim los tsim kua muag, los yog zoo li cov ntaub plaub-viscose siv hauv kev lag luam, uas yog tuab heev! Dab tsi peb yuav tsum tau hnav yog ruaj, hnav-tiv taus, xis nyob, thiab lub teeb, yog li feem ntau ntawm cov khaub ncaws peb hnav yog ua los ntawm woven fabrics thiab knitted fabrics, uas yog, woven fabrics thiab knitted fabrics. Cia peb qhia dab tsi yog woven npuag? Dab tsi yog knitted ntaub? Dab tsi yog lawv cov yam ntxwv thiab qhov txawv ntawm ob qho tib si yog dab tsi?
Woven fabrics thiab knitted fabrics muaj lawv tus kheej cov yam ntxwv hauv kev siv tshuab, cov qauv ntaub, cov yam ntxwv ntawm cov ntaub, thiab cov khoom tiav siv vim cov tshuab sib txawv thiab cov txheej txheem.
(I) Fabric koom haum muaj pes tsawg leeg
1. Woven npuag: cov ntaub npuag ua los ntawm ob lub tshuab ntawm yarns teem perpendicular rau ib leeg, uas yog kab rov tav thiab ntsug tshuab, uas yuav tsum tau interwoven ntawm ib lub loom raws li ib txoj cai. Cov xov paj nyob rau hauv qhov kev taw qhia warp yog hu ua warp yarn, thiab cov xov paj nyob rau hauv txoj kev weft yog hu ua weft yarn!
2. Knitted fabric: Npuag tsim los ntawm weaving yarn rau hauv loops, muab faib ua weft knitting thiab warp knitting.
2.1. Weft knitted npuag yog pub cov xov paj rau hauv lub koob ua haujlwm ntawm lub tshuab knitting los ntawm kev taw qhia weft, kom cov xov paj yog khoov rau hauv cov voj voog nyob rau hauv ib ntus thiab sib txuas nrog ib leeg.
2.2. Warp knitted npuag yog siv ib lossis ob peb pawg ntawm cov xov paj sib npaug, uas tau pub rau hauv txhua qhov kev ua haujlwm ntawm lub tshuab knitting hauv kev coj ua warp thiab raug looped tib lub sijhawm.
(II) Basic unit of fabric organization
(1) Woven fabric: Txhua qhov kev sib tshuam ntawm cov xov paj warp thiab cov xov paj weft hu ua lub koom haum taw tes, uas yog qhov tsawg tshaj plaws ntawm cov ntaub woven.
(2) Knitted npuag: Lub kauj yog qhov tsawg tshaj plaws ntawm cov ntaub knitted, thiab lub kauj yog tsim los ntawm lub voj qia thiab kab txuas ntxiv nyob rau hauv ib qho kev nkhaus.
(III) Cov tshuab thiab khoom siv sib txawv
1. Woven fabrics feem ntau yog woven los ntawm: rapier looms, dej dav hlau looms, thiab cua dav hlau looms!
2. Knitted fabrics feem ntau woven los ntawm: warp knitting machines, loj ncig knitting tshuab, thiab me me ncig knitting tshuab!
(IV) Qhov sib txawv ntawm cov qauv ntaub
(1) Woven fabrics: Vim hais tias cov warp thiab weft yarns interwoven, muaj ib co dabtsi yog khoov, thiab lawv tsuas khoov nyob rau hauv cov kev taw qhia perpendicular mus rau lub dav hlau ntaub. Qhov degree ntawm dabtsi yog khoov yog cuam tshuam nrog kev sib nrig sib nro ntawm warp thiab weft yarns, nrog rau qhov nruj ntawm cov yarns. Thaum lub woven npuag raug rau sab nraud nro, xws li longitudinal stretching, qhov nro ntawm warp yarn nce, khoov txo qis, thiab khoov ntawm cov xov paj weft nce. Yog hais tias lub longitudinal stretching txuas ntxiv mus txog rau thaum lub warp yarn yog kiag li straightened, cov ntaub shrinks tom qab. Thaum lub woven npuag yog raug rau sab nraud nro nyob rau hauv lub transverse kev taw qhia, qhov nro ntawm lub weft yarn nce, khoov txo, thiab khoov ntawm warp yarn nce. Yog hais tias lub transverse stretching txuas ntxiv mus txog rau thaum lub weft yarn yog kiag li straightened, cov ntaub shrinks longitudinally. Lub warp thiab weft yarns yuav tsis hloov dua siab tshiab, uas txawv ntawm knitted fabrics.
(2) Knitted fabrics: Vim tias lub kauj yog tsim los ntawm kev khoov ntawm cov xov paj hauv qhov chaw, thiab txhua lub kauj yog tsim los ntawm ib lub xov paj, thaum cov ntaub knitted raug rau sab nraud, xws li longitudinal stretching, khoov ntawm coil hloov, thiab qhov siab ntawm lub kauj kuj nce, thaum qhov dav ntawm lub kauj yuav txo qis. Yog hais tias qhov nro yog transverse stretching, qhov teeb meem yog qhov opposite. Qhov siab thiab dav ntawm lub kauj tuaj yeem pom tseeb tau hloov mus rau ib leeg nyob rau hauv qhov sib txawv nro. Yog li ntawd, lub extensibility ntawm knitted fabrics yog loj.
(V) Qhov txawv ntawm cov yam ntxwv ntawm lub koom haum ntaub
(1) Woven fabrics: Vim hais tias qhov txuas ntxiv thiab kev cog lus ntawm warp thiab weft yarns ntawm woven fabrics tsis zoo sib xws thiab tsis tau hloov dua siab tshiab, woven fabrics feem ntau tighter thiab stiffer.
(2) Knitted fabrics: Lawv tuaj yeem ncav cuag txhua qhov kev qhia thiab muaj elasticity zoo. Vim hais tias knitted fabrics yog tsim los ntawm qhov zoo li tus coils, lawv muaj breathability ntau dua thiab ib tug mos mos.
