Ntau lub tuam txhab tsim cov ntaub tsis-woven uas ib txwm tsis tsim nyog, qee zaum nrog nyias sab thiab tuab nruab nrab, nyias sab laug, lossis tsis sib xws softness thiab hardness. Qhov laj thawj tseem ceeb yog vim li cas hauv qab no tsis ua kom zoo thaum lub sijhawm tsim khoom.
Vim li cas cov ntaub tsis-woven muaj qhov tsis sib xws nyob rau hauv tib txoj kev ua haujlwm?
Kev sib xyaw tsis sib xws ntawm qhov tsis tshua muaj melting point fibers thiab cov pa fibers
Cov fibers sib txawv muaj lub zog tuav sib txawv. Feem ntau hais lus, low melting point fibers muaj zog tuav ntau dua li cov pa fibers thiab tsis tshua muaj kev tawg. Yog hais tias qhov tsawg melting point fibers yog unevenly dispersed, qhov chaw uas tsis muaj melting point fibers yuav tsis tsim ib tug txaus mesh qauv, uas ua rau thinner non-woven fabrics thiab thicker cheeb tsam nrog ntau dua melting point fiber ntau.
Tsis tiav melting ntawm tsawg melting point fibers
Lub melting tsis tiav ntawm qhov tsawg melting point fibers feem ntau yog vim tsis txaus kub. Rau cov ntaub tsis-woven nrog lub hauv paus hnyav, nws feem ntau tsis yooj yim kom muaj qhov kub tsis txaus, tab sis rau cov khoom uas muaj lub hauv paus hnyav thiab tuab tuab, tshwj xeeb yuav tsum tau them rau seb nws puas txaus. Cov ntaub tsis-woven nyob rau ntawm ntug feem ntau yog thicker vim muaj cua sov txaus, thaum cov ntaub tsis-woven nyob rau hauv nruab nrab yog feem ntau yuav tsim ib tug thinner non-woven npuag vim tsis txaus tshav kub.
Lub shrinkage tus nqi ntawm fibers yog kuj siab
Txawm hais tias nws yog cov pa fiber ntau lossis cov ntsiab lus melting tsawg, yog tias cov thermal shrinkage tus nqi ntawm cov fibers siab, cov thickness tsis sib xws kuj yuav tshwm sim thaum lub sij hawm tsim cov ntaub tsis-woven vim muaj teeb meem shrinkage.
Vim li cas cov ntaub tsis-woven muaj qhov tsis sib xws softness thiab hardness?
Cov laj thawj rau qhov tsis sib xws ntawm softness thiab hardness ntawm non-woven fabrics nyob rau hauv tib txoj kev ua haujlwm feem ntau zoo ib yam li cov laj thawj rau qhov tsis sib xws uas tau hais los saum no, thiab cov laj thawj tseem ceeb yuav suav nrog cov ntsiab lus hauv qab no:
1. Tsawg melting point fibers thiab cov pa fibers yog sib xyaw tsis sib xws, nrog rau cov khoom uas muaj cov ntsiab lus siab melting point ntau dua thiab cov ntsiab lus qis dua yog softer.
2.Incomplete melting ntawm low melting point fibers ua rau non-woven fabrics yuav softer
3.Qhov siab shrinkage tus nqi ntawm fibers kuj tuaj yeem ua rau tsis sib xws softness thiab hardness ntawm non-woven fabrics.
Vim li cas hluav taws xob zoo li qub ib txwm tsim thaum lub sijhawmkev tsim cov ntaub tsis-woven?
1.Cov huab cua qhuav dhau lawm thiab cov av noo tsis txaus.
2.Thaum tsis muaj roj ntawm cov fiber ntau, tsis muaj cov tshuaj tiv thaiv zoo li qub ntawm cov fiber ntau. Vim tias cov dej noo rov qab ntawm polyester paj rwb yog 0.3%, qhov tsis muaj cov tshuaj tiv thaiv zoo li qub ua rau muaj hluav taws xob zoo li qub thaum tsim khoom.
3.Dua rau cov qauv molecular tshwj xeeb ntawm tus neeg sawv cev roj, polyester paj rwb muaj yuav luag tsis muaj dej ntawm tus neeg sawv cev roj, ua rau nws yooj yim los tsim hluav taws xob zoo li qub thaum tsim khoom. Lub smoothness ntawm tes xav yog feem ntau proportional rau cov hluav taws xob zoo li qub, thiab smoother polyester paj rwb, ntau dua qhov hluav taws xob zoo li qub.
4.Nrog rau kev ua kom lub tshuab ua kom qhuav, nws tseem ceeb heev kom tshem tawm cov paj rwb tsis muaj roj kom zoo thaum lub sij hawm pub mis kom tsis txhob muaj hluav taws xob zoo li qub.
Yog vim li cas rau kev tsim cov paj rwb tawv tom qab ua haujlwm yob yog qhwv nrog paj rwb
Thaum lub sij hawm tsim khoom, qhov entanglement ntawm paj rwb rau ntawm qhov chaw ua hauj lwm yob feem ntau tshwm sim los ntawm cov roj cov ntsiab lus ntawm cov fibers, uas ua rau txawv txav coefficient ntawm cov fibers thiab rab koob ntaub. Cov fibers tso rau hauv qab ntawm rab koob daim ntaub, ua rau kev ua haujlwm yob ua entangled nrog paj rwb. Cov fibers entangled rau ntawm cov yob ua haujlwm tsis tuaj yeem txav mus los thiab maj mam yaj mus rau hauv cov paj rwb tawv los ntawm kev sib txhuam thiab kev sib txhuam ntawm rab koob thiab cov ntaub npuag. Txhawm rau tshem tawm cov paj rwb tangled, txoj kev txo qis ntawm kev ua haujlwm yob tuaj yeem siv los txav thiab tshem tawm cov tangled paj rwb ntawm yob.
Qhov tsim nyog tshaj plaws ua qhov ntsuas kub rau qhov qis melting point fibers
Tam sim no melting point ntawm low melting point fibers yog advertised li 110 ℃, tab sis qhov kub no tsuas yog softening kub ntawm tsawg melting point fibers. Yog li qhov tsim nyog tshaj plaws thiab ua kom sov kub yuav tsum tau ua raws li qhov yuav tsum tau ua kom tsawg kawg nkaus ntawm cov cua sov ntawm cov ntaub tsis-woven mus rau qhov kub thiab txias ntawm 150 ℃ rau 3 feeb.
Thinner non-woven fabrics muaj ntau dua rau qhov luv luv
Thaum winding non-woven npuag, cov khoom tiav ua tiav loj dua li nws tau dov, thiab ntawm tib lub winding ceev, kab ceev yuav nce. Thinner non-woven npuag yog nquag ncab vim qis qis, thiab luv luv yards tuaj yeem tshwm sim tom qab tau dov vim yog qhov nro tawm. Raws li rau cov khoom tuab thiab nruab nrab, lawv muaj zog tensile ntau dua thaum lub sij hawm tsim khoom, ua rau tsis tshua muaj zog thiab tsis tshua muaj peev xwm ua rau muaj teeb meem luv luv.
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.
