Puas yog kub dov tsis-woven npuag thiab cua kub tsis-woven ntaub yog tib yam?

Cov cua kub tsis-woven ntaub

Cov cua kub tsis-woven npuag belongs rau ib hom cua kub sib koom ua ke (kub-dov, cua kub) tsis-woven ntaub. Cov cua kub uas tsis yog-woven npuag yog tsim los ntawm kev siv cov cua kub los ntawm cov khoom siv ziab kom nkag mus rau hauv lub vev xaib fiber ntau tom qab cov fibers raug combed, cia nws ua kom sov thiab sib koom ua ke.

Cov txheej txheem cua kub sib txuas

Cov cua kub sib txuas yog hais txog kev tsim cov cua kub kom nkag mus rau cov fiber ntau mesh ntawm cov khoom siv ziab thiab yaj hauv qab cua sov los tsim kev sib txuas. Cov txheej txheem cua sov siv yog txawv, thiab kev ua tau zoo thiab cov qauv ntawm cov khoom tsim kuj sib txawv. Feem ntau, cov khoom ua los ntawm cov cua kub sib txuas muaj cov yam ntxwv xws li fluffiness, softness, zoo elasticity, thiab muaj zog warmth tuav, tab sis lawv lub zog yog tsawg thiab lawv yog feem ntau deformation.

Hauv kev tsim cov cua kub sib txuas, ib qho kev faib ua feem ntawm qhov qis melting point bonding fibers los yog ob-cov khoom siv fiber ntau feem ntau sib xyaw rau hauv lub vev xaib fiber ntau, los yog cov khoom siv hmoov sib kis tau siv los siv qee cov hmoov sib txuas rau lub vev xaib fiber ntau ua ntej nws nkag mus rau hauv chav ziab. Lub melting point ntawm hmoov yog qis dua cov fibers, thiab nws sai melts thaum rhuab, ua rau adhesion ntawm fibers.

Cov cua kub cua kub rau cov cua kub sib txuas yog feem ntau qis dua qhov melting point ntawm lub ntsiab fiber. Yog li ntawd, nyob rau hauv kev xaiv ntawm fibers, qhov sib txuam ntawm thermal zog ntawm lub ntsiab fiber ntau thiab kev sib txuas fiber ntau yuav tsum tau txiav txim siab, thiab qhov sib txawv ntawm lub melting point ntawm bonding fiber thiab lub melting point ntawm lub ntsiab fiber yuav tsum maximized kom txo cov thermal shrinkage tus nqi ntawm lub ntsiab fiber ntau thiab tswj nws cov khoom qub.

Lub zog ntawm kev sib txuas fiber ntau yog qis dua li cov fibers ib txwm, yog li cov nyiaj ntxiv yuav tsum tsis txhob loj dhau, feem ntau tswj ntawm 15% thiab 50%. Vim nws tsis tshua muaj thermal shrinkage tus nqi, ob lub ntsiab fibers yog heev haum rau siv nyob rau hauv ib leeg los yog raws li kev sib txuas fibers nyob rau hauv zus tau tej cov cua kub bonded nonwoven fabrics, tsim kom zoo point bonding lug. Cov khoom tsim los ntawm txoj kev no muaj lub zog siab thiab muag tes zoo li.

Kev siv cov cua kub tsis-woven ntaub

Fiber webs muaj li ntawm thermoplastic hluavtaws fibers tuaj yeem siv los ntawm thermal bonding, xws li polyester, nylon, polypropylene, thiab lwm yam. feem ntau siv hauv cov ntaub tsis-woven. Vim tias tsis muaj thermoplasticity ntawm fibers xws li paj rwb, ntaub plaub, hemp, thiab viscose, fiber ntau network tsim los ntawm cov fibers nkaus xwb tsis tuaj yeem txhawb nqa los ntawm thermal bonding. Txawm li cas los xij, ib qho me me ntawm fibers xws li paj rwb thiab ntaub plaub tuaj yeem muab ntxiv rau cov thermoplastic fiber ntau los txhim kho qee yam khoom ntawm cov ntaub tsis-woven, tab sis feem ntau yuav tsum tsis pub tshaj 50%. Piv txwv li, kub-kuav los tiag uas tsis yog-woven npuag ua los ntawm paj rwb / polyester nyob rau hauv ib tug 30/70 mixing ratio tuaj yeem txhim kho kev nqus dej noo, txhais tes, thiab softness, ua rau nws zoo heev rau kev siv hauv cov khoom kho mob thiab kev noj qab haus huv. Raws li cov paj rwb fiber ntau cov ntsiab lus nce, lub zog ntawm non-woven fabrics yuav txo. Ntawm chav kawm, rau fiber ntau webs tsim tag nrho ntawm cov tsis thermoplastic fibers, nws tseem tuaj yeem txiav txim siab siv cov hmoov sib kis thiab cov txheej txheem kub sib txuas rau kev txhawb nqa.

Kub dov tsis-woven npuag

Cov txheej txheem kub dov thiab cov txheej txheem cua kub yog ob qho tseem ceeb ntawm cov txheej txheem tsim khoom. Cov txheej txheem kub dov muaj xws li cua sov uas tsis yog-woven npuag raw cov ntaub ntawv ntawm qhov kub thiab txias thiab tom qab ntawd compressing lawv mus rau hauv ib qho tuab ntawm cov ntaub tsis-woven los ntawm cov txheej txheem dov. Kub bonded nonwoven fabrics tuaj yeem ua tiav los ntawm kev sib txawv cua sov. Txoj kev sib txuas thiab cov txheej txheem, hom fiber ntau thiab cov txheej txheem combing, thiab cov qauv hauv web yuav kawg cuam tshuam rau kev ua tau zoo thiab cov tsos ntawm cov ntaub tsis-woven.

Kub dov nplaum txoj kev

Rau cov fibers uas muaj cov ntsiab lus melting tsawg lossis ob-cov khoom siv fiber ntau, kev sib txuas kub dov lossis cov cua kub sib txuas tuaj yeem siv tau. Rau cov thermoplastic fibers zoo tib yam thiab fiber ntau sib xyaw nrog cov tsis thermoplastic fibers, kub dov kev sib txuas tuaj yeem siv tau.

Kub dov kev sib txuas txoj kev yog feem ntau haum rau nyias cov khoom nrog lub web qhov hnyav ntawm 20-200g / m, thiab qhov zoo tshaj plaws lub web qhov hnyav ntawm 20-80g / m. Yog tias lub vev xaib tuab dhau lawm, kev sib txuas ntawm cov txheej txheem nruab nrab yog qhov tsis zoo, thiab delamination yog qhov tshwm sim.

Cov cua kub sib txuas yog tsim rau cov khoom lag luam nrog ntau yam ntawm 16 ~ 2500g / m. Nyob rau hauv xyoo tas los no, txoj kev loj hlob ntawm nyias cov cua kub sib koom ua ke nonwoven fabrics tau nrawm, nrog rau ntau qhov ntau ntawm 16-100g / m.

Tsis tas li ntawd, thermal bonding kuj feem ntau siv rau hauv kev tsim cov ntaub ntawv tsis sib xws (xws liyaj laminated nonwoven fabrics), los yog raws li ib tug ntxiv txhais tau tias rau lwm txoj kev txhawb zog. Piv txwv li, sib tov ib qho me me ntawm qhov qis melting point fibers rau hauv lub vev xaib fiber ntau, ntxiv nrog rab koob punching, thiab tom qab ntawd kev sib txuas nrog cov cua kub tuaj yeem txhim kho lub zog thiab qhov ntev ntawm cov khoom siv rab koob punched.

Daim ntawv thov kub-kuav los tiag uas tsis yog-woven npuag

Cov khoom siv hluav taws xob kub kub muaj cov yam ntxwv ntawm siab fluffiness, zoo elasticity, mos tes xav, muaj zog warmth tuav, zoo breathability thiab permeability, tab sis lawv lub zog yog tsawg thiab lawv yog feem ntau deformation. Nrog rau txoj kev loj hlob ntawm kev ua lag luam, cov khoom siv hluav taws xob kub kub tau siv dav hauv kev tsim cov khoom siv pov tseg nrog lawv cov cim tshwj xeeb, xws li cov ntaub qhwv me nyuam, cov neeg laus cov ntaub so ntswg, cov ntaub qhwv rau cov poj niam cov khoom tu cev, cov ntaub so ntswg, cov phuam da dej, cov ntaub pua rooj pov tseg, thiab lwm yam; Cov khoom tuab yog siv los ua cov khaub ncaws tiv thaiv khaub thuas, ntaub pua chaw, cov hnab ntim me nyuam pw, cov txaj pw, rooj zaum cushions, thiab lwm yam. High density hot melt adhesive products can be used to make filter material, sound insulation material, shock absorption material, etc.

Dongguan Liansheng Nonwoven Technology Co., Ltd.tau tsim nyob rau hauv lub Tsib Hlis 2020. Nws yog ib tug loj-scale non-woven npuag ntau lawm enterprise integrating kev tshawb fawb thiab kev loj hlob, ntau lawm, thiab muag khoom. Nws tuaj yeem tsim ntau yam xim ntawm PP spunbond non-woven fabrics nrog qhov dav ntawm tsawg dua 3.2 meters los ntawm 9 grams mus rau 300 grams.
