Tau kawg. Kev txhim kho lub kua muag tsis kam ntawm spunbond nonwoven fabrics yog ib txoj haujlwm ua haujlwm nrog kev ua kom zoo ntawm ntau yam, los ntawm cov khoom siv raw thiab cov txheej txheem ntau lawm kom tiav. Tear resistance yog ib qho tseem ceeb rau kev nyab xeeb kev siv xws li cov khaub ncaws tiv thaiv, vim nws ncaj qha cuam tshuam rau cov khoom siv tau ntev thiab kev nyab xeeb thaum raug rub tawm thiab puas.
Cov hauv qab no yog cov txheej txheem tseem ceeb rau kev txhim kho lub kua muag tsis kam ntawm spunbond nonwoven fabrics:
Raw Material Optimization: Tsim lub hauv paus muaj zog
Xaiv High-Toughness Polymers:
Siab Molecular Nyhav / Nqaim Molecular Nyhav Distribution Polypropylene: Ntev molecular chains thiab ntau dua entanglement ua rau inherently ntau zog thiab toughness.
Copolymerization lossis Blending Modification: Ntxiv me me ntawm polyethylene lossis lwm yam elastomers rau polypropylene. Kev taw qhia ntawm PE tuaj yeem hloov kho cov khoom siv crystallization tus cwj pwm, txhim kho kev yooj yim thiab cuam tshuam, yog li txhim kho tsim kua muag.
Ntxiv Impact Modifiers: Qhia tshwj xeeb elastomers lossis roj hmab theem raws li cov ntsiab lus kev ntxhov siab tuaj yeem nqus tau thiab tawg lub zog tsim kua muag, tiv thaiv kev tawg tawm.
Siv cov fibers ua haujlwm siab:
PET thiabPP Composites: Qhia txog polyester fibers thaum lub sij hawm spunbonding txheej txheem. PET, nrog nws cov qauv siab thiab lub zog, ua tiav PP fibers, ua kom muaj zog tag nrho ntawm lub network fiber ntau.
Siv bicomponent fibers, xws li "Island-type" lossis "core-sheath" cov qauv. Piv txwv li, siv PET ua "core" rau lub zog thiab PP ua "lub tsho" rau thermal adhesion, sib txuas qhov zoo ntawm ob qho tib si.
Cov txheej txheem ntau lawm tswj: Optimizing Fiber Network Structure
Qhov no yog cov kauj ruam tseem ceeb tshaj plaws hauv kev txhim kho kua muag.
Spinning thiab Drawing txheej txheem:
Txhim kho Fiber Strength: Optimizing drawing ceev thiab kub tso cai rau tag nrho orientation thiab crystallization ntawm polymer macromolecules, uas ua rau high-strength, high-modulus monofilament fibers. Muaj zog monofilaments yog lub hauv paus ntawm cov ntaub muaj zog.
Tswj Fiber Fineness: Thaum ua kom muaj kev ruaj ntseg ntau lawm, tsim nyog txo txoj kab uas hla fiber ntau ua rau cov fibers hauv ib cheeb tsam, ua rau cov fiber ntau network denser thiab tso cai rau kev thauj khoom zoo dua thaum muaj kev ntxhov siab.
Cov txheej txheem tsim thiab txhawb nqa lub vev xaib:
Txhim kho Fiber Orientation Randomness: Zam kev sib tw unidirectional fiber ntau. Optimizing airflow web forming technology tsim ib qho isotropic fiber network. Nyob rau hauv txoj kev no, tsis hais txog ntawm qhov kev taw qhia ntawm lub zog tearing, ib tug loj tus naj npawb ntawm transverse fibers tiv nws, uas ua rau muaj kev sib npaug siab kua muag kuj.
Optimized Kub Rolling txheej txheem:
Bond Point Design: Ua haujlwm "me me-dot densely packed" yob-up qauv. Me me, tuab cov ntsiab lus sib raug zoo ua kom muaj kev ntxhov siab txaus yam tsis muaj kev cuam tshuam nrog kev ntxhov siab ntau ntxiv rau hauv lub network loj thiab tsis txhob muaj kev ntxhov siab.
Kub thiab Siab: Precisely tswj qhov kub dov kub thiab siab ua kom tag nrho cov fusion ntawm fibers ntawm daim ntawv cog lus cov ntsiab lus tsis muaj siab dhau heev lawm uas yuav puas los yog embrittle cov fibers lawv tus kheej.
Hydroentangling Reinforcement: Rau qee cov ntaub ntawv, hydroentangling yog siv los ua lwm txoj hauv kev los yog ntxiv rau kub dov. High-pressure dej jetting ua rau fibers rau entangle, tsim ib tug peb-dimensional mechanically interlocked qauv. Cov qauv no feem ntau ua tau zoo heev hauv kev tsim kua muag thiab ua rau cov khoom muag muag.
Finishing and Composite Technology: Qhia Txog Sab Nraud Reinforcement
Lamination / Composite Technology:
Qhov no yog ib txoj hauv kev ncaj nraim thiab siv tau zoo. Spunbond nonwoven fabric yog composited nrog xov paj, woven fabric, los yog lwm txheej ntawm spunbond ntaub nrog ib tug txawv orientation.
Lub hauv paus ntsiab lus: High-strength filaments nyob rau hauv lub mesh los yog woven npuag tsim ib tug macroscopic reinforcing skeleton uas ho inhibits tsim kua muag propagation. Qhov no yog qhov tseeb ntawm cov qauv uas feem ntau siv rau hauv cov khaub ncaws tiv thaiv kev tiv thaiv siab, qhov uas tsim kua muag feem ntau yog los ntawm txheej txheej txheej txheej.
Impregnation tiav:
Lub spunbond ntaub yog impregnated nrog ib tug haum polymer emulsion thiab ces kho nyob rau hauv lub fiber kev sib tshuam. Qhov no ua rau kom muaj zog sib txuas ntawm fibers, yog li txhim kho lub zog tsim kua muag, tab sis yuav txi qee qhov softness thiab breathability.
Cov ntsiab lus thiab cov ntsiab lus tseem ceeb
Txhawm rau txhim kho lub kua muag tsis kam ntawm spunbond nonwoven fabrics, ib qho kev ua ntau yam yog qhov yuav tsum tau ua:
Qib | Txoj kev | Lub luag haujlwm tseem ceeb
Raw Khoom | Siv high-toughness polymers, muab kev hloov kho, ntxiv elastomers | Txhim khu lub zog thiab extensibility ntawm tus kheej fibers
Txheej txheem ntau lawm | Txhim kho kev tsim qauv, daim ntawv isotropic fiber ntau webs, optimize kub dov/hydroentangling txheej txheem | Tsim kom muaj zog, tsis sib xws fiber ntau network nrog kev ntxhov siab zoo dispersion
Tiav | Laminate nrog yarns, impregnate | Qhia cov txheej txheem kev txhawb nqa sab nraud los tiv thaiv kev tsim kua muag
Lub tswv yim tseem ceeb tsis yog tsuas yog ua kom txhua cov fiber ntau muaj zog, tab sis kuj kom ntseeg tau tias tag nrho cov fiber ntau network qauv tuaj yeem cuam tshuam zoo thiab nqus tau lub zog thaum ntsib lub zog tsim kua muag, tsis yog tso cai rau kev ntxhov siab thiab sib kis sai ntawm ib qho chaw.
Hauv kev tsim khoom tiag tiag, kev sib xyaw tsim nyog tshaj plaws yuav tsum raug xaiv raws li cov khoom siv kawg, kev siv nyiaj txiag, thiab kev ua haujlwm sib npaug (xws li huab cua permeability thiab softness). Piv txwv li, rau cov khaub ncaws tiv thaiv kev ua haujlwm siab, cov khoom siv sib xyaw ua ke ntawm "lub zog spunbond npuag + high-barrier film + mesh reinforcement txheej" yog tus qauv kub rau tib lub sijhawm ua kom lub siab ua kua muag, puncture resistance thiab tshuaj tiv thaiv.
Dongguan Liansheng Nonwoven Technology Co., Ltd.tau tsim nyob rau hauv lub Tsib Hlis 2020.
