Cov yam ntxwv thiab kev siv cov khoom siv raw spunlaced nonwovens | JINHAOCHENG

Cov ntaub tsis-woven uas tsis yog-wovenabric Muaj ntau yam khoom siv raw, tab sis tsis yog txhua yam khoom siv fiber tuaj yeem txhim kho los ntawm kev sib xyaw ua ke nrog cov txheej txheem tsim khoom, kev siv khoom, tus nqi tsim khoom thiab lwm yam. Ntawm cov tshuaj fibers siv feem ntau, ntau dua 97% ntawm cov khoom spunlaced siv polyester fiber los txhim kho lub zog thiab kev ruaj khov ntawm cov khoom; viscose fiber yog ntau cov khoom siv fiber raw. Nws muaj cov yam ntxwv ntawm kev nqus dej zoo, tsis-pilling, yooj yim ntxuav, kev puas tsuaj ntuj thiab lwm yam. Siv dav hauv cov khoom spunlaced; polypropylene fiber yog siv dav hauv cov ntaub ntawv huv hauv kev sib cuag nrog tib neeg daim tawv nqaij vim nws tus nqi qis, tsis khaus rau tib neeg daim tawv nqaij, tsis ua xua thiab fluffy; vim yog tus nqi ntawm cov paj rwb nqus dej thiab cov kev xav tau zoo ntawm cov khoom siv raw, paj rwb nqus dej tsis siv dav hauv thaj chaw ntawm spunlacing, tab sis cov khoom sib xyaw ntawm cov paj rwb nqus dej thiab lwm yam fibers tau siv hauv thaj chaw kho mob thiab daim ntaub so.

Cov thev naus laus zis Spunlaced reinforcement muaj kev hloov pauv zoo rau cov khoom siv raw. Nws tuaj yeem ua kom tsis yog cov thermoplastic fibers xwb, tab sis kuj tseem muaj cov cellulose fibers uas tsis yog thermoplastic. Nws muaj qhov zoo ntawm cov txheej txheem tsim khoom luv luv, kev kub ceev, cov zis siab, tsis muaj wu dyeing rau ib puag ncig thiab lwm yam. Cov khoom siv Spunlaced reinforcement muaj cov khoom siv kho tshuab zoo thiab tsis tas yuav tsum tau txhawb nqa los ntawm cov nplaum.Cov ntaub tsis-woven uas tsis muaj xovtsis yooj yim rau fluff thiab poob tawm. Qhov kev ua tau zoo ntawm cov ntaub yog ze li ntawm cov ntaub ib txwm muaj, nrog rau qee qib ntawm kev mos thiab kev xav; muaj ntau yam khoom, uas tuaj yeem yog tiaj tus lossis jacquard: ntau hom qhov (puag ncig, oval, square, ntev). Cov kab (kab ncaj, peb ceg, herringbone, cov qauv) thiab lwm yam.

Piv nrog rau kev siv koob txhaj tshuaj, cov neeg ua haujlwm spunlaced muaj peev xwm hloov kho tau ntau dua rau cov khoom uas muaj qhov sib txawv ntawm qhov chaw; ntxiv rau, cov ntaub nyias nyias spunlaced nonwovens yooj yim rau decompose thiab tuaj yeem siv thiab pov tseg, lossis rov ua dua tshiab rau kev sib tsoo pov tseg. Qhov no yog ib hom ntaub zoo rau ib puag ncig. Nrog ntau qhov zoo, cov khoom spunlaced sai sai nyob hauv kev lag luam ntawm cov ntaub lag luam xws li cov ntaub huv (kev kho mob, so, thiab lwm yam), cov ntaub ua los ntawm cov khoom siv hluavtaws (roj teeb diaphragm, khaub ncaws hauv pem teb, cov ntaub ntawv tsim kho, thiab lwm yam). Nrog rau kev txhim kho ntawm cov thev naus laus zis spunlaced nonwovens, kev ua tau zoo ntawm spunlaced nonwovens tau txhim kho tas li, ntau yam khoom muaj ntau dua thiab ntau dua, thiab kev siv tau nthuav dav. Nrog nws cov kev ua tau zoo tshwj xeeb, nws cov feem ntawm kev lag luam tau nce siab thiab siab dua.

Cov khoom siv ntxuav huv

Muaj ntau yam khoom lag luam ntawm kev ua lag luam nonwovens, uas siv dav hauv cov khoom pov tseg xws li hauv tsev, kev kho mob thiab kev saib xyuas tus kheej, nrog rau lwm yam khoom. Txawm li cas los xij, cov ntaub rags uas muaj peev xwm muag tau loj heev suav nrog yuav luag ib nrab ntawm cov feem ntawm kev ua lag luam. Cov khoom so feem ntau suav nrog daim ntaub so kev saib xyuas tus kheej, daim ntaub so kev lag luam thiab daim ntaub so hauv tsev. Tsis tas li ntawd, qhov kev thov rau spunlaced nonwovens hauv kev noj qab haus huv tab tom nthuav dav, xws li cov ntaub so menyuam yaus, cov ntaub so, cov khoom ntxuav hauv tsev thiab lwm yam. Tam sim no cov khoom spunlaced tau siv dav. Yav dhau los, spunlaced nonwovens kuj tau siv rau hauv yuav luag txhua yam khoom, xws li cov ntaub so menyuam yaus kub dhau thiab cov ntaub so huv rau poj niam, nrog rau spunlaced nonwovens.

Cov ntaub ntawv kho mob thiab kev noj qab haus huv

Cov ntaub ntawv kho mob huv kuj yog ib qho tseem ceeb ntawm kev siv cov ntaub tsis-woven. Cov khoom muaj xws li cov ntaub thaiv qhov txhab, cov khaub ncaws phais thiab lub kaus mom phais, daim ntaub qhwv, paj rwb thiab lwm yam khoom. Cov yam ntxwv ntawm cov fiber viscose zoo ib yam li cov paj rwb fiber. Kev ua tau zoo ntawm cov ntaub tsis-woven uas tsim nrog qhov sib piv ntawm 70x30 yog ze heev rau cov paj rwb gauze ib txwm muaj, uas ua rau nws muaj peev xwm rau cov khoom spunlaced los hloov cov paj rwb gauze, thiab cov khoom spunlaced ua los ntawm cov tshuaj tua kab mob chitin fiber tsis tsuas yog muaj peev xwm tua kab mob zoo xwb, thiab tuaj yeem txhawb kev kho qhov txhab zoo.

Daim ntaub tawv hluavtaws

Cov ntaub tsis-woven uas tsis yog spunlaced yog mos, xis nyob, ua pa tau thiab noo noo permeable, nrog rau cov ntaub tsis-woven thiab cov qhov me me uas tsis-woven. Tom qab daim ntaub hauv paus tau coated, qhov kev ua tau zoo ntawm cov khoom yog ze li ntawm cov tawv nqaij ntuj thiab muaj kev sim zoo. Cov ntaub tsis-woven uas tsis-woven nrog cov txheej txheem cross-laying muaj lub zog thiab kev hloov pauv los hloov cov ntaub ntawv ib txwm muaj vim muaj qhov sib txawv me me ntawm lub zog longitudinal thiab transverse.

Cov khoom siv lim dej

Cov ntaub tsis yog woven uas tsis muaj xov muaj qhov me me thiab faib sib npaug, yog li lawv tuaj yeem siv ua cov ntaub lim. Piv txwv li, cov ntaub uas tsis muaj xov ua los ntawm cov ntaub ntawv tiv taus kub thiab cov ntaub woven muaj qhov zoo ntawm kev lim dej raug, kev ruaj khov zoo thiab lub neej ntev, uas tsis tuaj yeem piv rau lwm cov ntaub tsis yog woven.

Qhov saum toj no yog kev qhia txog cov yam ntxwv thiab daim ntawv thov ntawm spunlaced nonwovens. Yog tias koj xav paub ntau ntxiv txog spunlaced nonwovens, thov koj xav tiv tauj peb.
