Cov ntaub ntawv tsis-woven yog hom tshwj xeeb ntawm cov ntaub uas tsis siv cov cuab yeej ua haujlwm tiaj tiaj. Txog rau hnub tim, muaj ntau ntau hom khoom, nrog rau cov txheej txheem rau lawv siv. Lub Scope ntawm cov khoom ntawm no ntau yam kuj yog dav. Feem ntau, cov ntaub tsis-woven yog siv hauv kev tsim kho thiab kev ua liaj ua teb, nrog rau kev txiav.

keeb kwm me ntsis

Thawj zaug, cov khoom siv tsis-woven tau tsim nyob rau hauv lub thib ob ib nrab ntawm lub xyoo pua 19th nyob rau hauv teb chaws USA. Thawj canvases ntawm no ntau yam yog tsim los ntawm hluavtaws fibers fastened ua ke nrog starch. Cov khoom no, hu ua pellone, tsis tau txais kev faib tshwj xeeb hauv xyoo pua 19th.

Tam sim no nws yog tsim los ntawm ntau lub tuam txhab Lavxias. Piv txwv li, ib yam khoom zoo heev ntawm hom no yog tsim los ntawm Podolsk Hoobkas ntawm cov ntaub ntawv tsis-woven "Ves Mir", nrhiav tau nyob rau hauv 2000.

Density

Cov khoom siv tsis-woven tuaj yeem ua ntau txoj hauv kev, muaj qhov sib txawv thickness, zoo li thiab lub hom phiaj. Txawm li cas los xij, tus yam ntxwv tseem ceeb ntawm cov canvases feem ntau yog lub zog. Qhov kawg, nyob rau hauv lem, nyob ntawm qhov ntom ntom ntawm cov khoom. Qhov kev ntsuas no nyob rau hauv pawg sib txawv tuaj yeem sib txawv li ntawm 10-600 g / m 2. Yog li, piv txwv li:

• Stitched non-woven npuag feem ntau muaj qhov ntom ntawm 235-490 g / m 2.
• Needle-punched npuag muaj 210 g/m2.
• Density of woven material - 216-545 g/m2.
• Flizelin muaj qhov ntom ntom ntawm 90-110 g / m 2.
• Rau xov stitched fabrics, daim duab no yog 63-310 g/m2.
• Density of non-woven fabric glued - 40-330 g/m2.

Fabrics ntawm hom no tuaj yeem tsim kho tshuab lossis nplaum. Lub hauv paus ntawm ib qho khoom siv zoo li no yog ib daim ntaub ua los ntawm ntuj thiab hluavtaws fibers nteg nyob rau hauv kab. Kom tau txais cov qauv fibrous, xws li lub vev xaibsib pab.

Mechanical ntau lawm

Kev sib txuas ntawm lub hauv paus ntawm cov khoom siv tsis yog siv cov cuab yeej siv no yog tsim los siv cov xov ntxiv. Hauv kev siv tshuab, piv txwv li, cov ntaub ntawv canvas-stitched yog ua. Nyob rau hauv cov ntaub ntawv no, lub warp fibers yog fastened ua ke los ntawm stitching lawv nrog threads. Thaum siv rab koob-punched tshuab, cov ntsiab lus tsim cov canvas yog ua ntej entangled nrog ib leeg. Qhov tshwm sim yog cov ntaub ntom ntom. Txhawm rau muab lub zog ntau dua, nws yog stitched nrog tuab threads. Nyob rau hauv rooj plaub no, cov cuab yeej tshwj xeeb nrog cov ntawv sau yog siv.

Kev tsim cov ntaub tsis-woven los ntawm txoj kev nplaum

Cov thev naus laus zis no yog siv hauv kev tsim khoom ntawm ntau yam ntawm cov ntaub tsis-woven. Kev sib txuas ntawm fibers hauv daim ntaub hauv qhov notsim los ntawm impregnating lawv nrog ntau yam ntawm cov nplaum compositions. Feem ntau, hluavtaws latex yog siv rau kev ua. Lwm cov cuab yeej siv yog kub nias. Nyob rau hauv cov ntaub ntawv no, cov fibers yog glued ua ke nrog thermoplastics ntawm qhov kub siab heev.

Qee zaum cov cuab yeej qub tshaj plaws kuj tseem siv rau kev tsim cov ntaub ntawv tsis-woven - ntawm cov tshuab ntawv. Nws yog nrog kev siv cov cuab yeej zoo li no uas cov pellet tau tsim hauv Asmeskas. Nyob rau hauv rooj plaub no, lub binder tuaj yeem qhia ncaj qha rau hauv huab cua nkag mus rau hauv lub tshuab, lossis twb tau mus rau hauv lub vev xaib tiav lawm.

Siv quilted canvases

Txawm li cas los xij, nyob rau hauv rooj plaub tom kawgkoob-punched non-woven cov ntaub ntawv feem ntau yuav tsum tau ntxiv impregnated nrog nplaum compositions. Qhov tseeb yog tias nws cov fibers yog nruj heev, thiab yog li ntawd, nyob rau hauv ib tug dawb lub xeev, lawv muaj peev xwm nkag mus rau lub sab nrauv ntaub ntawm khaub ncaws thiab spoils nws tsos.

Nws yog txoj kev siv rab koob uas tseem tsim cov khoom siv tsis-woven ntau tshaj plaws - dornite. Geotextiles yog siv nyob rau hauv kev tsim kho ntawm cov kav dej, nteg tawm cov nyom, lub hauv paus tsev, thiab lwm yam. Tsis tas li ntawd, lub koob-punched txoj kev yog qee zaum siv los tsim cov hom nrov tshaj plaws ntawm cov ntaub npog rau tsev cog khoom thiab hotbeds - spunbond. Txawm li cas los xij, feem ntau hom canvas no tseem ua los ntawm txoj kev nplaum (kub nias).

Ob hom no kuj yog qhov xav tau hauv kev lag luam. Lub ntsiab kom zoo dua ntawm threaded fabrics yog ntau yam nyob rau hauv tsos. Txoj kev no tuaj yeem tsim cov ntaub ntawv nyias nyias thiab cov rooj tog loj. Cov khaub ncaws hnav, hnav khaub ncaws yav tsaus ntuj, hnav ris tsho, phuam qhwv caj dab, cov ntaub qhwv tsis-woven feem ntau yog ua los ntawm kev siv tshuab no.

Qhov zoo ntawm cov ntaub ntawv stitched yog cov qauv ruaj khov thiab kev nyiam huv. Raws li qhov taw qhia xws li hnav tsis kam, lawv zoo dua rau txhua yam ntawm cov ntaub ntawv tsis-woven. Cov ntaub no feem ntau yog siv rau xaws khaub ncaws da dej thiab puam suits.

Feem ntau, xws li cov khoom tsis-woven yog tsim los ntawm kev sib tovpaj rwb thiab kapron fibers. Nws feem ntau yog siv los ua khaub ncaws. Piv txwv li, nws tau muab tso rau hauv dab tshos, cov hlua khi thiab cov hlua kom muab cov rigidity tom kawg. Cov ntaub ntawv tsim los ntawm cov tshuab ntawv feem ntau yog siv los tsim ntau hom kev hnav khaub ncaws kho mob.

Raws li koj tuaj yeem pom, thaj tsam ntawm cov ntaub tsis-woven hauv peb lub sijhawm yog qhov dav heev. Lawv cov yam ntxwv ntawm kev ua tau zoo heev ua rau lawv tseem ceeb rau kev xaws ntau hom khaub ncaws, cov nroj tsuag loj hlob, txhim kho cov kav dej, thiab lwm yam. Cov thev naus laus zis ntawm cov khoom siv no tsis yog qhov nyuaj, thiab yog li ntawd lawv cov nqi feem ntau yog tsawg. Yeej, qhov no piav qhia txog qhov muaj koob meej ntawm qhov ntau yam ntawm canvases.
