Ziziphi iintlobo zee-Nonwovens?
Ii-Airlaid Nonwovens
Xa kuthelekiswa nezinye iitekhnoloji ze-nonwovens, i-airlaid inamandla akhethekileyo okubeka phantsi iifayibha ezimfutshane, nokuba yi-100% pulp fibers, okanye imixube ye-pulp kunye neefayibha ezimfutshane ezenziwe ngobuchule, ukuze zenze i-homogeneous and continuous web. Kunokwenzeka ukuxuba iipowders okanye iifayibha ezifunxa kakhulu ngaloo ndlela zenze ii-webs ezifunxa kakhulu.

Ukubopha Ngomoya (Ukubopha Ngobushushu)
Ukubophelela ngomoya luhlobo lokubophelela ngobushushu olubandakanya ukusetyenziswa komoya oshushu kumphezulu welaphu elingelolukiweyo. Ngexesha lenkqubo yokubophelela ngomoya, umoya oshushu uhamba ngemingxunya ekwiplenum engaphezulu kwento engelolukiweyo.

I-Meltblown
Ii-nonwovens ezinyibilikisiweyo ziveliswa ngokukhupha iifayibha zepolymer ezinyibilikisiweyo nge-spin net okanye i-die equlathe imingxunya efikelela kwi-40 nge-intshi nganye ukwenza iifayibha ezinde ezibhityileyo ezisoluliweyo kwaye zipholiswe ngokudlulisa umoya oshushu phezu kweefayibha njengoko ziwela kwi-die. I-web ephumayo iqokelelwa ibe yimiqulu kwaye emva koko iguqulwe ibe ziimveliso ezigqityiweyo.

I-Spunlace (i-Hydrotentanglement)
I-Spunlace (ekwaziwa ngokuba yi-hydroentanglement) yinkqubo yokubopha kwi-webs ezimanzi okanye ezomileyo ezenziwe nge-carding, airlaying okanye wet-laying, ilaphu elibotshelelweyo eliphumayo lingabalulekanga. Le nkqubo isebenzisa ii-jets zamanzi ezinoxinzelelo oluphezulu, ezingena kwi-web, zibethe ibhanti yokuhambisa (okanye "ucingo" njengakwi-conveyor yokwenza iphepha) kwaye zibuyele umva zibangele ukuba ii-fiber zibambe. I-Spunlace nonwoven fabric ezisetyenzisiweyo kwii-staple fibres ezimfutshane, ezona zidumileyo zii-viscose kunye nee-polyester staple fibers kodwa i-polypropylene kunye ne-cotton nazo ziyasetyenziswa. Izicelo eziphambili ze-spunlace ziquka ii-wipes, ii-facial sheet masks kunye neemveliso zonyango.

I-Spunlaid (i-Spunbond)
I-Spunlaid, ekwabizwa ngokuba yi-spunbond, ii-nonwovens zenziwa kwinkqubo enye eqhubekayo. Iifayibha ziyasontwa zize zisasazwe ngqo kwi-web ziziphambukisi okanye ziqondiswe ngemijelo yomoya. Le ndlela ikhokelela kwisantya sebhanti esikhawulezayo, kunye neendleko eziphantsi.

Ukunyibilika/i-SMS
I-Spunbond idityaniswe nee-nonwovens ezinyibilikisiweyo, nto leyo eyenza ukuba zibe yimveliso eneeleya ebizwa ngokuba yi-SMS (spun-melt-spun). Ii-nonwovens ezinyibilikisiweyo zine-fiber diameters ezincinci kakhulu kodwa azizo iilaphu ezomeleleyo. Iilaphu ze-SMS, ezenziwe ngokupheleleyo nge-PP azinamanzi kwaye zilungile ngokwaneleyo ukuba zisetyenziswe njengeelaphu ezilahlwayo. I-Melt-blown idla ngokusetyenziswa njenge-filter media, ikwazi ukubamba amasuntswana amancinci kakhulu. I-Spunlaid ibotshelelwe yi-resin okanye ngobushushu.

I-Wetlaid
Kwinkqubo yokuxuba amanzi, iifayibha zestaple ezinobude obufikelela kwi-12 mm, ezidla ngokuxutywa ne-viscose okanye i-pulp yomthi, zixhonywa emanzini, kusetyenziswa amatanki amakhulu. Emva koko i-water-fiber- okanye i-water-pulp-dispersion iyapompelwa kwaye igcinwe rhoqo kwintambo yokwenza. Amanzi ayatsalwa, ahluzwe aze aphinde asetyenziswe. Ngaphandle kweefayibha zokwenziwa, iifayibha zeglasi ze-ceramic kunye ne-carbon zinokucutshungulwa.
