Yiziphi izinhlobo ze-Nonwovens?
Izindwangu Ezingalukwanga Ezifakwe Ngendiza
Uma kuqhathaniswa nezinye ubuchwepheshe obungelukiwe, i-airlaid inekhono eliyingqayizivele lokubeka imicu emifushane, kungaba imicu ye-pulp engu-100%, noma ingxube yemicu ye-pulp kanye nemicu yokwenziwa emfushane, ukuze kwakheke i-web ehambisanayo neqhubekayo. Kungenzeka futhi ukuxuba impuphu noma imicu emunca kakhulu ngaleyo ndlela kudale imicu emunca kakhulu.

Ukubopha Komoya (Ukubopha Okushisayo)
Ukubopha ngomoya uhlobo lokubopha okushisayo oluhilela ukusetshenziswa komoya oshisayo ebusweni bendwangu engalukiwe. Ngesikhathi senqubo yokubopha umoya oshisayo, umoya oshisayo ugeleza ngemigodi e-plenum ngaphezu kwezinto ezingalukiwe.

Ukuncibilika
Ama-nonwoven ancibilikisiwe akhiqizwa ngokukhipha imicu ye-polymer encibilikisiwe nge-spin net noma i-die equkethe izimbobo ezingafika ku-40 nge-intshi ngayinye ukuze kwakheke imicu emide emincane eyelulwa futhi ipholiswe ngokudlulisa umoya oshisayo phezu kwemicu njengoba iwela ku-die. I-web ephumelayo iqoqwa ibe yimiqulu bese iguqulwa ibe yimikhiqizo eqediwe.

I-Spunlace (i-Hydrotentanglement)
I-Spunlace (eyaziwa nangokuthi i-hydroentanglement) inqubo yokubopha ama-webs ane-fibrous amanzi noma omile enziwe ngokufaka amakhadibhodi, ukufaka umoya noma ukubeka okumanzi, indwangu eboshiwe ephumayo ibe yi-nonlued. Le nqubo isebenzisa ama-jets amanzi aqinile, acindezelayo aphezulu angena ku-web, ashaye ibhande lokuhambisa (noma "ucingo" njengase-conveyor yokwenza iphepha) bese ebuyela emuva okwenza ama-fiber abambeke. Izindwangu ezingalukiwe ze-Spunlace ezisebenzisa ama-fiber amafushane ayisisekelo, athandwa kakhulu yi-viscose kanye ne-polyester staple fibers kodwa i-polypropylene kanye ne-cotton nazo ziyasetshenziswa. Izicelo eziyinhloko ze-spunlace zifaka phakathi ama-wipes, ama-facial sheet mask kanye nemikhiqizo yezokwelapha.

I-Spunlaid (i-Spunbond)
Ama-nonwoven aqoshiwe, abizwa nangokuthi i-spunbond, enziwa ngenqubo eyodwa eqhubekayo. Ama-fibre ayaphothwa bese ehlakazwa ngqo kuwebhu yiziphazamisi noma angaqondiswa ngemifudlana yomoya. Le ndlela iholela ekusheshiseni kwebhande ngokushesha, kanye nezindleko ezishibhile.

Ukuncibilika/i-SMS
I-Spunbond ihlanganiswe ne-nonwovens ezipheshulwe ngokuncibilika, yazenza umkhiqizo onezingqimba obizwa ngokuthi i-SMS (spun-melt-spun). I-nonwovens ezipheshulwe ngokuncibilika zine-diameter encane kakhulu ye-fiber kodwa azizona izindwangu eziqinile. Izindwangu ze-SMS, ezenziwe ngokuphelele nge-PP azingeni manzi futhi zinhle ngokwanele ukuba zisebenze njengezindwangu ezilahlwayo. I-Melt-blown ivame ukusetshenziswa njenge-filter media, ikwazi ukubamba izinhlayiya ezincane kakhulu. I-Spunlaid iboshelwa yi-resin noma ngokushisa.

I-Wetlaid
Enqubweni yokudonsa amanzi, imicu eyisisekelo enobude obufika ku-12 mm, evame ukuhlanganiswa ne-viscose noma i-pulp yokhuni, ilenga emanzini, kusetshenziswa amathangi amakhulu. Ngemva kwalokho ukusabalala kwe-water-fiber-noma i-water-pulp-dispersion kuyapompa futhi kuhlale kufakwa ocingweni olubumbayo. Amanzi ayamuncwa, ahlungwe futhi aphinde asetshenziswe. Ngaphandle kwemicu yokwenziwa, imicu ye-glass ceramic kanye ne-carbon ingacutshungulwa.
