Yog dab tsicov ntaub tsis yog woven? Cov ntaub tsis yog wovenyog ib yam khoom zoo li ntaub ua los ntawm cov fiber staple (luv) thiab cov fiber ntev (ntev ntev), sib txuas ua ke los ntawm kev kho tshuaj lom neeg, tshuab, cua sov lossis cov kuab tshuaj. Lo lus no siv rau hauv kev lag luam tsim khoom siv ntaub los qhia txog cov ntaub, xws li cov ntaub xav, uas tsis yog ntaub lossis knitted. Qee cov ntaub tsis yog ntaub tsis muaj zog txaus tshwj tsis yog tias tau densified lossis txhawb nqa los ntawm kev txhawb nqa. Nyob rau hauv xyoo tas los no, cov ntaub tsis yog ntaub tau dhau los ua lwm txoj hauv kev rau polyurethane ua npuas ncauj.
Cov Khoom Siv Raw
Polyester yog cov fibers uas siv ntau tshaj plaws hauv Tebchaws Meskas; olefin thiab nylon yog siv rau lawv lub zog, thiab paj rwb thiab rayon yog siv rau kev nqus dej. Qee cov acrylic, acetate, thiab vinyon kuj raug siv.
Cov fibers raug xaiv raws li lawv cov khoom thiab kev ua tau zoo uas xav tau hauv kev siv kawg. Cov fibers tshiab, zoo tshaj plaws yog nyiam dua li cov fibers rov siv dua lossis rov ua dua. Ob qho tib si staple thiab filament fibers raug siv, thiab nws muaj peev xwm sib xyaw cov fibers ntawm qhov ntev sib txawv nrog rau cov fibers ntawm cov pab pawg sib txawv. Kev xaiv cov fibers nyob ntawm cov khoom lag luam uas tau tshaj tawm, qhov kev saib xyuas feem ntau muab rau nws, thiab qhov kev cia siab lossis xav tau kev ruaj khov. Ib yam li hauv kev tsim cov ntaub, tus nqi ntawm cov fibers siv yog qhov tseem ceeb, vim nws cuam tshuam rau tus nqi ntawm cov khoom kawg.
Cov yam ntxwv ntawmcov ntaub tsis woven yob
- Cov yam ntxwv tshwj xeeb uas cov ntaub tsis yog woven muaj nyob ntawm kev sib xyaw ua ke ntawm cov yam tseem ceeb hauv nws cov khoom tsim tawm. Cov yam ntxwv ntawm cov ntaub no muaj ntau yam.
- Cov tsos ntawm cov ntaub tsis yog woven yuav zoo li ntawv, zoo li xav, lossis zoo ib yam li cov ntaub woven.
- Lawv tej zaum yuav muaj ib txhais tes mos mos, ruaj khov, lossis lawv tej zaum yuav tawv, tawv ncauj, lossis dav dav uas tsis yooj ywm.
- Lawv tej zaum yuav nyias li nyias li daim ntawv so tes lossis tuab dua ntau zaus.
- Lawv kuj tseem yuav yog translucent lossis opaque.

hom ntaub tsis woven
Nov yog plaub hom khoom tsis-woven tseem ceeb: Spunbound / Spunlace, Airlaid, Drylaid thiab Wetlaid. Tsab xov xwm no piav qhia txog cov hom tseem ceeb no kom meej.
Plaub hom khoom tsis-woven tseem ceeb thiab feem ntau yog:
- Spunbound/Spunlace.
- Tso rau hauv huab cua.
- Qhuav.
- Wetlaid
Spunbound / Spunlace
Cov ntaub uas raug muab sib txuas ua ke yog tsim los ntawm kev muab cov filaments uas raug rho tawm, sib txuas rau ntawm txoj siv sia hauv ib txoj kev sib xws ua raws li kev sib txuas cov fibers. Cov fibers raug sib cais thaum lub sijhawm tso web los ntawm cov dav hlau cua lossis cov nqi hluav taws xob electrostatic. Cov kev pabcuam sau feem ntau yog perforated kom tiv thaiv cov cua ntws los ntawm kev cuam tshuam thiab nqa cov fibers hauv txoj kev tsis tswj hwm. Kev sib txuas ua rau lub zog thiab kev ncaj ncees rau lub web los ntawm kev siv cov yob kub lossis cov koob kub kom yaj cov polymer thiab sib txuas cov fibers ua ke. Txij li thaum kev taw qhia molecular ua rau lub ntsiab lus yaj, cov fibers uas tsis tau kos ntau tuaj yeem siv ua cov fibers thermal binding. Polyethelene lossis random ethylene-propylene copolymers yog siv ua qhov chaw sib txuas qis yaj.
Cov khoom siv spunbound siv rau hauv cov ntaub pua plag, geotextiles, thiab cov khoom siv kho mob / tu cev pov tseg, cov khoom siv tsheb, kev tsim kho vaj tse thiab cov khoom ntim khoom.

Airlaid
Cov txheej txheem ntawm airlaying yog cov txheej txheem tsim cov ntaub tsis-woven uas tawg mus rau hauv cov kwj deg txav mus los sai thiab condenses lawv mus rau hauv lub vijtsam txav mus los ntawm kev siv lub siab lossis lub tshuab nqus tsev.
Cov ntaub airlaid feem ntau yog ua los ntawm cov ntoo pulp thiab muaj lub zog nqus tau zoo. Nws tuaj yeem sib xyaw nrog qhov sib piv ntawm SAP kom txhim kho nws lub peev xwm ntawm kev nqus dej ntub. Airlaid non-woven kuj tseem hu ua ntawv qhuav non-woven. Cov nonwoven yog ua los ntawm cov txheej txheem airlaying. Thauj cov woodpulp mus rau hauv lub pob ntawm cov cua kom ua rau cov fibers tawg thiab sib sau ua ke ntawm lub web ntab. Airlaid non-woven yog txhawb nqa los ntawm web.
Cov khoom siv tsis-woven airlaid siv rau hauv ntau yam khoom sib txawv thoob plaws ntau yam kev lag luam suav nrog; kev sib xyaw ua ke ntawm cov khaub ncaws, cov khoom kho mob thiab kev tu cev, cov ntaub paj ntaub thiab cov khoom lim.
Qhuav Laid
Cov ntaub pua plag qhuav feem ntau yog tsim los ntawm kev siv cov xov staple ntuj lossis tib neeg ua. Kev tsim cov ntaub pua plag qhuav feem ntau muaj 4 kauj ruam:
Kev npaj cov fiber staple -> Kev qhib, kev ntxuav, kev sib tov & kev sib xyaw -> Carding -> kev tso web.
Cov txiaj ntsig ntawm kev tsim cov ntaub tsis-woven uas qhuav muaj xws li; Cov qauv isotropic ntawm lub web, cov webs voluminous tuaj yeem tsim tau thiab ntau yam fibers ua tau xws li ntuj, hluavtaws, iav, hlau thiab carbon.
Cov khoom tsis yog ntaub uas qhuav yog siv los ntawm ntau yam khoom xws li cov ntaub so kom zoo nkauj thiab cov ntaub so menyuam yaus mus rau cov khoom lim dej haus.
Wetlaid
Cov ntaub tsis yog woven uas ntub dej yog cov ntaub tsis yog woven uas ua los ntawm cov txheej txheem ua ntawv hloov kho. Qhov ntawd yog, cov fibers uas yuav siv tau muab dai rau hauv dej. Lub hom phiaj tseem ceeb ntawm kev tsim cov ntaub tsis yog woven uas ntub dej yog los tsim cov qauv nrog cov yam ntxwv ntawm cov ntaub, feem ntau yog kev ywj pheej thiab lub zog, ntawm qhov ceev uas ze rau cov uas cuam tshuam nrog kev ua ntawv.
Cov tshuab ntawv tshwj xeeb yog siv los cais cov dej ntawm cov fibers los ua ib daim ntawv sib xws, uas tom qab ntawd raug sib txuas thiab ziab. Hauv kev lag luam yob zoo 5 -10% ntawm cov ntaub tsis yog woven yog ua los ntawm kev siv cov thev naus laus zis ntub.
Cov khoom siv Wetlaid siv rau ntau yam lag luam thiab cov khoom lag luam. Qee cov khoom siv feem ntau uas siv cov thev naus laus zis tsis yog ntaub ntub suav nrog; Daim ntawv hnab tshuaj yej, daim ntaub npog ntsej muag, Shingle thiab ntawv ua los ntawm cov xov paj hluavtaws.
Qee lwm hom ntaub tsis-woven suav nrog: Composite, Meltblown, Carded/Carding, Koob punch, Thermal bonded, Chemical bonded thiab Nanotechnology.

Keeb kwm thiab qhov zoo ntawm cov ntaub tsis woven xav tias
Lub hauv paus chiv keeb ntawm cov ntaub tsis yog cov khoom zoo nkauj. Qhov tseeb, lawv yog los ntawm kev siv cov khib nyiab fibrous lossis cov fibers zoo thib ob uas tseem tshuav los ntawm cov txheej txheem kev lag luam xws li kev xaws lossis kev ua tawv. Lawv kuj yog los ntawm kev txwv cov khoom siv raw piv txwv li thaum thiab tom qab Tsov Rog Thoob Ntiaj Teb Zaum Ob lossis tom qab ntawd hauv cov tebchaws communist hauv Central Europe. Qhov kev txo hwj chim thiab tus nqi no tau kawg ua rau qee qhov yuam kev hauv kev siv tshuab thiab kev lag luam; nws kuj yog lub luag haujlwm rau ob qho kev nkag siab yuam kev txog cov ntaub tsis yog woven: lawv xav tias yog (pheej yig) hloov pauv; ntau tus kuj koom nrog lawv nrog cov khoom pov tseg thiab vim li ntawd tau xav txog cov ntaub tsis yog woven ua cov khoom pheej yig, tsis zoo.
Tsis yog txhua yam khoom siv uas tsis yog woven siv tau pov tseg xwb. Feem ntau ntawm cov khoom siv no yog siv rau kev siv tas mus li, xws li kev siv rau hauv cov ntaub interlinings, ru tsev, geotextile, tsheb lossis kev siv rau hauv pem teb thiab lwm yam. Txawm li cas los xij, ntau yam khoom siv uas tsis yog woven, tshwj xeeb tshaj yog cov uas tsis hnyav, feem ntau yog siv ua cov khoom siv pov tseg lossis siv rau hauv cov khoom siv pov tseg. Hauv peb qhov kev xav, qhov no yog lub cim qhia txog kev ua haujlwm zoo. Kev siv pov tseg tsuas yog ua tau rau cov khoom siv pheej yig uas tsom mus rau cov yam ntxwv tseem ceeb thiab kev ua tau zoo thiab muab rau lawv yam tsis muaj kev kho kom zoo nkauj tsis tsim nyog.
Feem ntau cov ntaub tsis yog woven, txawm tias siv pov tseg los tsis siv, yog cov khoom siv high-tech, ua haujlwm tau zoo, piv txwv li muaj qhov nqus tau zoo heev lossis khaws cia rau cov ntaub so, lossis muaj qhov mos mos, hla dhau thiab tsis muaj cov yam ntxwv ntub rau cov uas siv rau hauv cov khoom siv tu cev, nrog rau cov yam ntxwv zoo tshaj plaws rau kev siv kho mob hauv chav phais, lossis muaj peev xwm lim tau zoo dua vim lawv qhov loj me thiab kev faib tawm, thiab lwm yam. Lawv tsis tau tsim nrog lub hom phiaj ntawm kev pov tseg tab sis kom ua tiav lwm yam kev xav tau. Lawv feem ntau tau dhau los ua pov tseg vim yog cov kev lag luam uas lawv siv hauv (kev tu cev, kev kho mob) thiab ntawm lawv cov nqi tsim nyog. Thiab kev pov tseg feem ntau tsim kom muaj txiaj ntsig ntxiv rau cov neeg siv. Vim tias cov khoom pov tseg tsis tau siv dua li, ces muaj kev lees paub tias lawv muaj tag nrho cov yam ntxwv xav tau piv rau cov ntaub ntxuav rov qab.
