Kodi Mitundu ya Nonwovens Ndi Chiyani?
Airlaid Nonwovens
Poyerekeza ndi matekinoloje ena a nonwovens, airlaid ili ndi kuthekera kwapadera koyika ulusi waufupi, mwina 100% ulusi wa zamkati, kapena kusakaniza kwa zamkati ndi ulusi wamfupi wopangidwa, kuti apange ukonde wofanana komanso wopitilira.Ndizothekanso kusakaniza mu ufa wapamwamba kwambiri kapena ulusi potero kupanga ukonde woyamwa kwambiri.

Mpweya Kupyolera mu Bonding (Thermal Bonding)
Kupyolera mu kulumikiza mpweya ndi mtundu wa mgwirizano wotentha womwe umaphatikizapo kugwiritsa ntchito mpweya wotentha pamwamba pa nsalu yopanda nsalu.Panthawi yomangirira mpweya, mpweya wotentha umayenda m'mabowo a plenum pamwamba pa zinthu zosawomba.

Meltblown
Ma meltblown nonwovens amapangidwa ndi ulusi wosungunuka wa polima wosungunuka kudzera pa ukonde wozungulira kapena kufa wokhala ndi mabowo 40 pa inchi kuti apange ulusi wopyapyala wautali womwe umatambasulidwa ndikuziziritsidwa podutsa mpweya wotentha pamwamba pa ulusiwo ukagwa kuchokera kufa.Ukonde wotsatirawu umasonkhanitsidwa kukhala mipukutu ndikusinthidwa kukhala zinthu zomalizidwa.

Spunlace (Hydrotentanglement)
Spunlace (yomwe imadziwikanso kuti hydroenanglement) ndi njira yolumikizirana ndi ulusi wonyowa kapena wowuma wopangidwa ndi ma carding, airlaying kapena kunyowa, zomwe zimapangitsa kuti nsalu yomangika ikhale yosawomba.Njirayi imagwiritsa ntchito majeti abwino, othamanga kwambiri amadzi omwe amalowa pa intaneti, kugunda lamba (kapena "waya" monga momwe amapangira mapepala) ndikubwerera kumapangitsa kuti ulusiwo utseke.Nsalu zokhala ndi spunlace zomwe zimagwiritsidwa ntchito ndi ulusi wanthawi yayitali, zodziwika kwambiri ndi ulusi wa viscose ndi polyester koma polypropylene ndi thonje zimagwiritsidwanso ntchito.Ntchito zazikulu za spunlace ndi monga zopukuta, zophimba kumaso ndi mankhwala azachipatala.

Spunlaid (Spunbond)
Spunlaid, yomwe imatchedwanso spunbond, nonwovens amapangidwa mosalekeza.Ulusi umalungidwa kenako nkumwazikana mwachindunji pa intaneti ndi zopotoka kapena utha kuwongoleredwa ndi mitsinje ya mpweya.Njirayi imatsogolera kuthamanga kwa lamba mwachangu, komanso mtengo wotsika mtengo.

Spunmelt/SMS
Spunbond yaphatikizidwa ndi ma nonwovens osungunuka, kuwapanga kukhala chinthu chosanjikiza chotchedwa SMS (spun-melt-spun).Zovala zosungunula zosungunuka zili ndi ma diameter a ulusi wabwino kwambiri koma si nsalu zolimba.Nsalu za SMS, zopangidwa kwathunthu kuchokera ku PP ndizopanda madzi komanso zabwino zokwanira kuti zikhale ngati nsalu zotayidwa.Melt-blown nthawi zambiri amagwiritsidwa ntchito ngati zosefera, kutha kujambula tinthu tating'onoting'ono.Spunlaid imamangidwa ndi utomoni kapena thermally.

Wetlaid
Munjira yonyowa, ulusi woyambira mpaka 12 mm utali wa ulusi, womwe nthawi zambiri umasakanizidwa ndi viscose kapena zamkati zamatabwa, umayimitsidwa m'madzi, pogwiritsa ntchito akasinja akulu.Pambuyo pake, ulusi wamadzi- kapena madzi-zamkati-kubalalitsidwa amapopedwa ndikuyikidwa mosalekeza pa waya wopangidwa.Madzi amayamwa, kusefedwa ndi kubwezeretsedwanso.Kupatula ulusi wopangira, magalasi a ceramic ndi kaboni ulusi amatha kukonzedwa.
