Txheej txheem-Kev Sib Txuas Kev Ua Haujlwm: Kev Ntsuas Kom Paub meej
Kev sib raug zoo ntawm cov txheej txheem tsim khoom thiab kev ua haujlwm ntawm cov ntaub txiav txim siab qhov tsim nyog ntawm cov ntaub ntawv tsis yog rau kev siv tshwj xeeb. Hauv qab no yog qhov tob tob rau hauv cov kev sib tshuam no:
1. Softness thiab Flexibility
Kev xaiv ntawm cov txheej txheem ntau lawm cuam tshuam rau kev xav tactile thiab pliability ntawm nonwoven fabrics:
Spunlace: Cov txheej txheem no tsim cov ntaub mos mos tshaj plaws vim tsis muaj cov tshuaj sib txuas ua ke. Lub dav hlau dej 'kev ua siab mos mos khaws cia cov fibers 'natural kev ntxhib los mos, ua spunlace zoo tagnrho rau cov khoom uas tuaj rau hauv cov tawv nqaij ncaj qha, xws li cov ntaub so me nyuam thiab lub ntsej muag lub ntsej muag.
Thermal Bonding: Thaum txoj kev no ua rau muaj zog thiab du fabrics, nws softness feem ntau qis dua spunlace. Los ntawm kev tswj cov kev sib txuas ntawm qhov kub thiab txias, cov tuam ntxhab tuaj yeem ua tiav qhov sib npaug ntawm qhov muag thiab cov qauv kev ntseeg siab.
Koob punching: Koob- cov ntaub npuag yog mos mos vim cov txheej txheem txheej txheem. Lub interlocking fibers feem ntau tsim ib qho kev ntxhib los mos, uas tsis haum rau kev sib cuag ntawm daim tawv nqaij tab sis zoo tagnrho rau cov ntawv thov kev lag luam uas xav tau kev ua haujlwm ntev.
2. Absorbency thiab Moisture Management
Lub absorbency ntawm nonwoven fabrics nyob ntawm cov txheej txheem ntau lawm thiab fiber ntau:
Spunlace: Nrog siab absorbency, spunlace fabrics nyiam rau kev kho mob thiab tu cev daim ntaub ntawv. Cov qauv qhib tsim los ntawm hydroentanglement tso cai rau cov kua dej sai sai, ua rau nws tsim nyog rau cov ntaub so ntswg thiab cov ntaub qhwv phais.
Meltblown: Cov txheej txheem no tsim cov khoom tsis yog- nqus tau. The dense web of ultrafine fibers is excellent for blocking liquids but unsuitable for applications requiring high water retention.
Ntug dej -Laid: Cov txheej txheem ntub dej -ntev ua kom muaj kev tswj hwm ntawm cov khoom siv fiber ntau, tsim cov ntaub nrog cov qib nqus absorbency. Qhov no ua rau lawv haum rau cov ntaub so tshwj xeeb thiab cov dej noo-sensitive applications.
3. Lub zog thiab kav ntev
Lub zog yog qhov tseem ceeb hauv ntau daim ntawv thov kev lag luam thiab kev tiv thaiv, qhov twg cov ntaub tsis yog ntaub yuav tsum tiv taus cov neeg kho tshuab kev ntxhov siab:
Koob punching: Koob- xuas nrig ntaus cov ntaub zoo tshaj plaws hauv lub zog tensile thiab durability vim cov fibers interlocked. Cov khoom no ua rau lawv zoo tagnrho rau geotextiles thiab hnyav- cov lim dej.
Thermal Bonding: Cov ntsiab lus sib txuas tsim los ntawm tshav kub thiab siab muab kev tsim kua muag zoo heev. Cov txheej txheem no yog dav siv rau cov khoom xws li cov tsoos tsho pov tseg thiab ntim khoom.
Spunlace: Thaum softer thiab hloov tau yooj yim dua, spunlace fabrics muaj lub zog nruab nrab, uas tuaj yeem txhim kho los ntawm kev siv siab - tensile fibers lossis nce web ntom.
4. Lim Efficiency
Filtration efficiency nyob ntawm fiber ntau txoj kab uas hla thiab lub web ntom, ncaj qha cuam tshuam los ntawm cov txheej txheem ntau lawm:
Meltblown: Ua cov fibers ultrafine nrog diameters hauv micrometer ntau, xa cov kev pom zoo tshwj xeeb. Qhov no yog qhov tseem ceeb rau kev kho mob -qib qhov ncauj qhov ntswg, HEPA lim, thiab roj absorbents.
Spunlace: Txawm hais tias tsis tshua muaj txiaj ntsig zoo dua li meltblown, spunlace fabrics tuaj yeem ua tiav kev pom zoo los ntawm kev ua kom pom cov fiber ntau thiab qhov ntom ntom. Qhov no ua rau lawv haum rau daim ntaub ntawv xws li phais drapes.
Ntug dej -Laid: Qhov sib xws ntawm cov ntub dej- cov ntaub npuag ua kom pom kev ua haujlwm zoo ib yam, tshwj xeeb tshaj yog rau cov ntawv thov hauv kev lag luam hluav taws xob.
5. Kev cuam tshuam ib puag ncig
Sustainability tau dhau los ua qhov tseem ceeb rau cov neeg yuav khoom:
Ntug dej -Laid: Cov txheej txheem no tau zoo- haum rau cov fibers ntuj, ua rau cov khoom siv biodegradable thiab compostable fabrics. Txawm li cas los xij, kev siv dej yuav tsum tau tswj kom txo tau qhov cuam tshuam ib puag ncig.
Meltblown thiab Thermal Bonding: Cov txheej txheem no vam khom rau cov khoom siv hluavtaws zoo lipolypropylene (PP), uas tsawg dua eco- phooj ywg. Kev tsim kho tshiab hauv bio-raws li polymers yog pab txo qis lawv qhov chaw ib puag ncig.
Spunlace: Txawm hais tias dej- mob hnyav, kev nce qib hauv cov dej rov ua dua tshiab ua rau cov txheej txheem spunlace ruaj khov dua.
