Dab tsi yog Hom Nonwovens?

Dab tsi yog Hom Nonwovens?
Airlaid Nonwovens
Piv nrog rau lwm yam nonwovens technologies, airlaid muaj lub peev xwm los nteg luv fibers, xws li 100% pulp fibers, los yog sib tov ntawm pulp thiab luv txiav hluavtaws fibers, tsim ib homogeneous thiab tas mus li lub web.Nws kuj tseem tuaj yeem sib xyaw hauv cov hmoov superabsorbent lossis fibers yog li tsim cov webs absorbent heev.

Huab cua los ntawm Bonding (Thermal Bonding)
Los ntawm kev sib txuas ntawm huab cua yog ib hom kev sib txuas thermal uas cuam tshuam nrog kev siv cov cua sov rau saum npoo ntawm cov ntaub uas tsis yog ntaub.Thaum lub sij hawm dhau los ntawm cov txheej txheem kev sib txuas ntawm huab cua, cua sov cua ntws los ntawm qhov nyob hauv lub plenum saum cov khoom siv nonwoven.

Meltblown
Meltblown nonwovens yog tsim los ntawm extruding melted polymer fibers los ntawm ib tug spin net los yog tuag muaj txog li 40 qhov ib nti los tsim ntev nyias fibers uas yog stretched thiab txias los ntawm cua kub dhau lub fibers thaum lawv poob los ntawm cov tuag.Lub vev xaib resultant tau sau rau hauv yob thiab tom qab hloov mus rau cov khoom tiav.

Spunlace (Hydrotentanglement)
Spunlace (tseem hu ua hydroentanglement) yog txheej txheem kev sib koom ua ke rau cov ntaub ntub dej los yog qhuav fibers ua los ntawm ob qho tib si carding, airlaying los yog ntub-ntws, cov ntaub ntawv sib koom ua ke yog nonwoven.Cov txheej txheem no siv cov dav hlau siab siab ntawm cov dej uas nkag mus rau hauv lub vev xaib, ntaus txoj siv conveyor (los yog "xaim" zoo li hauv papermaking conveyor) thiab thaws rov qab ua rau cov fibers entangle.Spunlace non-woven fabrics siv luv staple fibers, nrov tshaj plaws yog viscoseand polyester staple fibers tab sis polypropylene thiab paj rwb kuj siv.Cov ntawv thov tseem ceeb rau spunlace suav nrog cov ntaub so, daim npog ntsej muag thiab cov khoom siv kho mob.

Spunlaid (zeeg)
Spunlaid, tseem hu ua spunbond, nonwovens yog ua nyob rau hauv ib tug tas mus li txheej txheem.Fibers yog spun thiab ces ncaj qha dispersed mus rau hauv ib lub web los ntawm deflectors los yog tau coj mus rau hauv cov huab cua ntws.Cov txheej txheem no ua rau kev siv ceev ceev, thiab cov nqi pheej yig dua.

Spunmelt / SMS
Spunbond tau ua ke nrog yaj-tshuab nonwovens, conforming lawv mus rau hauv ib txheej khoom hu ua SMS (spun-melt-spun).Melt-blown nonwovens muaj fiber ntau zoo diameters tab sis tsis muaj zog fabrics.SMS ntaub, ua tiav los ntawm PP yog dej-repellent thiab zoo txaus los ua cov ntaub ntawv pov tseg.Melt-blown feem ntau yog siv los ua lim xov xwm, tuaj yeem ntes cov khoom zoo heev.Spunlaid yog sib txuas los ntawm cov resin los yog thermally.

Wetlaid
Nyob rau hauv cov txheej txheem ntub dej, staple fibers txog li 12 hli fiber ntev, feem ntau tov nrog viscose lossis ntoo pulp, raug tshem tawm hauv dej, siv cov tso tsheb hlau luam loj.Tom qab ntawd cov dej-fiber- los yog dej-pulp-dispersion yog pumped thiab tsis tu ncua tso rau ntawm ib txoj hlua hlau.Cov dej yog nqus tawm, lim thiab rov siv dua.Dhau li ntawm cov hluavtaws fibers, iav ceramic thiab carbon fibers tuaj yeem ua tiav.
