Ni ubuhe bwoko bwa Nonwovens?
Airlaid Nonwovens
Ugereranije nubundi buryo bwa tekinoloji idahwitse, airlaid ifite ubushobozi budasanzwe bwo gushyira fibre ngufi, yaba 100% ya fibre fibre, cyangwa imvange ya pulp na bigufi byacishijwe bugufi, kugirango ikore urubuga rumwe kandi rukomeza.Birashoboka kandi kuvanga ifu ya superabsorbent cyangwa fibre bityo ugashiraho imiyoboro ikurura cyane.

Umwuka Binyuze mu Guhuza (Guhuza Ubushyuhe)
Binyuze mu kirere ni ubwoko bwo guhuza ubushyuhe burimo no gukoresha umwuka ushyushye hejuru yumwenda udoda.Mugihe cyo guhuza ikirere, umwuka ushyushye unyura mu mwobo uri muri plenum hejuru yibikoresho bidoda.

Meltblown
Meltblown nonwovens ikorwa mugusohora fibre ya polymer yashonze ikoresheje urushundura ruzunguruka cyangwa igapfa igizwe nu mwobo ugera kuri 40 kuri santimetero kugirango ube fibre ndende ndende irambuye kandi ikonjeshwa no kunyuza umwuka ushyushye hejuru ya fibre mugihe ziguye zipfa.Urubuga rwibisubizo rwakusanyirijwe mumuzingo hanyuma ruhindurwa kubicuruzwa byarangiye.

Spunlace (Hydrotentanglement)
Spunlace (izwi kandi nka hydroentanglement) ni inzira yo guhuza imiyoboro itose cyangwa yumye ya fibrous ikozwe namakarita, guhumeka ikirere cyangwa gushira-ibishishwa, imyenda ihambiriye kuba idoda.Ubu buryo bukoresha indege nziza zumuvuduko mwinshi wamazi yinjira mururubuga, gukubita umukandara wa convoyeur (cyangwa "wire" nko muri papermaking convoyeur) hanyuma ugasubira inyuma bigatuma fibre zifata.Kuzunguruka imyenda idoda ikoreshwa fibre ngufi, izwi cyane ni viscoseand polyester staple fibre ariko polypropilene na pamba nabyo birakoreshwa.Ibyingenzi byingenzi bisabwa harimo guhanagura, impapuro zo mumaso hamwe nibicuruzwa byubuvuzi.

Kuzunguruka (Spunbond)
Spunlaid, nanone yitwa spunbond, idoda ikozwe muburyo bumwe bukomeza.Fibre irazunguruka hanyuma igahita ikwirakwizwa kurubuga na deflectors cyangwa irashobora kwerekanwa numuyoboro.Ubu buhanga buganisha ku muvuduko wihuse, kandi bihendutse.

Spunmelt / SMS
Spunbond yahujwe no gushonga-kudoda, kubihuza nibicuruzwa byitwa SMS (spun-melt-spun).Gushonga-gushonga bitarimo imyenda ya fibre nziza cyane ariko ntabwo ari imyenda ikomeye.Imyenda ya SMS, ikozwe rwose muri PP irwanya amazi kandi nziza kuburyo ikora nk'imyenda ikoreshwa.Gushonga-gukoreshwa akenshi nkibikoresho byo kuyungurura, gushobora gufata ibice byiza cyane.Spunlaid ihujwe na resin cyangwa ubushyuhe.

Igishanga
Mubikorwa bya wetlaid, fibre fibre ifite uburebure bwa mm 12 z'uburebure, akenshi ivangwa na viscose cyangwa ibiti byimbaho, ihagarikwa mumazi, ikoresheje tanki nini.Nyuma, amazi-fibre- cyangwa amazi-pulp-dispersion arapompa kandi agakomeza kubikwa kumurongo winsinga.Amazi arakurwa, akayungurura kandi akongera gukoreshwa.Usibye fibre synthique, glas ceramic na fibre fibre irashobora gutunganywa.
