Qhov sib txawv ntawm meltblown thiab spunbond

Meltblown fabric thiab non-woven fabric yeej yog tib yam. Meltblown npuag kuj muaj lub npe hu ua meltblown non-woven npuag, uas yog ib qho ntawm ntau cov ntaub tsis-woven.Spunbond non-woven npuagyog ib hom ntaub uas ua los ntawm polypropylene li raw khoom, uas yog polymerized rau hauv ib lub mesh los ntawm high-temperature drawing, thiab ces khi rau hauv ib lub ntaub siv kub dov txoj kev.

Cov txheej txheem sib txawv

Spunbond non-woven npuag thiab yaj tshuab tsis-woven npuag yog ob hom ntawm cov ntaub tsis-woven, tab sis lawv cov txheej txheem tsim khoom sib txawv.

(1) Cov kev cai rau cov khoom siv raw yog txawv. Spunbond yuav tsum muaj MFI ntawm 20-40g / min rau PP, thaum yaj tshuab xav tau 400-1200g / min.

(2) Qhov kub spinning txawv. Melt tshuab spinning yog 50-80 ℃ siab tshaj spunbond spinning.

(3) Lub stretching ceev ntawm fibers txawv. Spunbond 6000m / min, yaj tshuab 30km / min.

(4) Qhov kev ncua deb tsis yog cylindrical. Spunbond 2-4m, yaj cua tshuab 10-30cm.

(5) Txias thiab ncab tej yam kev mob txawv. Spunbond fibers tau kos siv 16 ℃ cua txias nrog lub siab zoo / tsis zoo, thaum lub tshuab ziab khaub ncaws yog tshuab siv ze 200 ℃ cua kub hauv chav tsev loj.

Cov khoom sib txawv ua haujlwm

Lub zog tawg thiab elongation ntawm spunbond ntaub yog ntau dua li cov ntaub meltblown, thiab tus nqi qis dua. Tab sis txhais tes xav thiab fiber ntau uniformity tsis zoo.

Meltblown ntaub yog fluffy thiab mos, nrog kev pom kev ua haujlwm siab, tsis muaj zog, thiab kev ua haujlwm zoo. Tab sis nws muaj zog tsawg thiab tsis zoo hnav tsis kam.

Kev sib piv cov yam ntxwv ntawm cov txheej txheem

Ib qho ntawm cov yam ntxwv ntawm cov ntaub nplaum uas tsis yog-woven yog tias cov fiber ntau fineness yog me me, feem ntau tsawg dua 10um (micrometers), feem ntau fibers muaj fineness ntawm 1-4um.

Lub zog sib txawv ntawm tag nrho cov kab spinning los ntawm lub nozzle ntawm meltblown tuag rau cov khoom siv tsis tuaj yeem tswj tau qhov sib npaug (vim qhov hloov pauv ntawm lub zog ncab los ntawm qhov kub thiab txias cua nrawm, nrog rau kev cuam tshuam ntawm huab cua txias thiab kub), uas ua rau sib txawv fineness ntawm meltblown fibers.

Lub uniformity ntawm fiber ntau nyob rau hauv spunbond nonwoven fabric web yog zoo dua li cov meltblown fibers, vim hais tias nyob rau hauv cov txheej txheem spunbond, cov txheej txheem spinning yog khov kho-lub xeev, thiab cov kev hloov nyob rau hauv stretching thiab txias tej yam kev mob yog me me.

Kev sib piv ntawm Crystallization thiab Orientation Degree

Lub crystallinity thiab orientation ntawm yaj cua tshuab fibers yog me dua li ntawmspunbond fiber ntau. Yog li ntawd, lub zog ntawm yaj cua tshuab fibers tsis zoo, thiab lub zog ntawm lub web fibers kuj tsis zoo. Vim tias qhov tsis zoo fiber ntau ntawm cov yaj tshuab tsis woven fabrics, qhov tseeb daim ntawv thov ntawm yaj cua tshuab nonwoven fabrics tsuas yog nyob ntawm tus yam ntxwv ntawm lawv cov ultrafine fibers.

Kev sib piv ntawm cov yaj cua tshuab fibers thiab spunbond fibers

Fiber ntev - spunbond yog ib tug ntev fiber, meltblown yog ib tug luv fiber

Fiber zog - spunbond fiber ntau zog> Meltblown fiber ntau zog

Fiber fineness - Meltblown fibers yog finer tshaj spunbond fibers

Kev sib piv thiab cov ntsiab lus ntawm cov txheej txheem spunbond thiab meltblown

Cov khoom sib txawv

1. Lub zog thiab durability: Feem ntau, lub zog thiab durability ntawmspunbond nonwoven ntaubyog siab tshaj cov meltblown nonwoven fabrics. Spunbond non-woven npuag muaj zog tensile zoo dua thiab stretchability, tab sis nws yuav ncab thiab deform thaum rub; Txawm li cas los xij, yaj tshuab tsis-woven npuag muaj qhov tsis zoo stretchability thiab nws yooj yim rau kev tawg ncaj qha thaum rub nrog quab yuam.

2. Breathability: Spunbond non-woven npuag muaj breathability zoo thiab tuaj yeem siv los ua lub ntsej muag kho mob thiab lwm yam khoom. Txawm li cas los xij, meltblown non-woven fabric muaj breathability tsis zoo thiab yog tsim nyog rau cov khoom xws li cov khaub ncaws tiv thaiv.

3. Kev ntxhib los mos thiab kev ntxhib los mos: spunbond non-woven npuag muaj ib qho kev ntxhib los mos thiab tus nqi qis, tab sis nws cov kev ntxhib los mos thiab fiber ntau tsis zoo, uas yog ntau dua nyob rau hauv txoj kab nrog cov kev xav tau ntawm qee yam khoom zam. Meltblown ntaub yog fluffy thiab mos, nrog kev pom kev ua haujlwm siab, tsis muaj zog, thiab kev ua haujlwm zoo. Tab sis nws muaj zog tsawg thiab tsis zoo hnav tsis kam.

4. Qhov saum npoo ntawm spunbond non-woven npuag feem ntau muaj cov qauv pom tseeb; Thiab meltblown non-woven npuag muaj ib tug kuj du nto nrog tsuas yog ob peb tus qauv me ntsis.

Txawv daim ntawv thov teb

Vim muaj cov khoom sib txawv thiab cov yam ntxwv ntawm ob hom non-woven fabrics, lawv daim ntawv thov teb kuj txawv.

1. Kev kho mob thiab kev noj qab haus huv: Spunbond non-woven fabric muaj breathability zoo thiab ib tug mos kov, haum rau siv nyob rau hauv kev kho mob thiab kev noj qab haus huv cov khoom xws li lub qhov ncauj qhov ntswg, phais gowns, thiab lwm yam. Meltblown non-woven fabric yog haum rau siv raws li ib tug lim txheej nyob rau hauv nruab nrab ntawm lub qhov ncauj qhov ntswg, tiv thaiv khaub ncaws, thiab lwm yam khoom.

2. Lwm cov khoom: Cov khoom muag muag thiab kev ntxhib los mos ntawm spunbond non-woven npuag yog tsim los ua cov khoom siv leisure, xws li rooj zaum npog, curtains, thiab lwm yam. Meltblown non-woven fabric muaj kev pom zoo thiab tsim nyog rau kev tsim ntau yam khoom siv lim.

Xaus

Hauv cov ntsiab lus, spunbond nonwoven npuag thiab meltblown nonwoven npuag muaj lawv tus kheej cov yam ntxwv thiab tsim nyog rau ntau qhov chaw. Cov neeg siv khoom tuaj yeem xaiv cov khoom tsim nyog raws li lawv cov khoom xav tau.
