Ndedzipi Mhando dzeNonwovens?
Airlaid Nonwovens
Zvichienzaniswa nemamwe matekinoroji asiriwo, airlaid ine yakasarudzika kugona kuisa pasi mapfupi faibha, angave 100% pulp fibers, kana musanganiswa wepulp uye mapfupi akachekwa ekugadzira fibers, kuumba homogeneous uye inoenderera webhu.Zvinogoneka zvakare kusanganisa mune superabsorbent poda kana fiber nekudaro kugadzira mawebhu anonwisa zvakanyanya.

Mhepo kuburikidza neBonding (Thermal Bonding)
Kuburikidza nemhepo yekubatanidza imhando yekubatanidza kupisa kunosanganisira kuiswa kwemhepo inopisa pamusoro pemucheka usina kuruka.Panguva yekubatanidza mhepo, mweya unopisa unoyerera nemumakomba ari muplenum pamusoro pezvinhu zvisina kuruka.

Meltblown
Meltblown nonwovens anogadzirwa neextruding akanyunguduka polymer fibers kuburikidza ne spin net kana kufa ine maburi anosvika makumi mana pa inch kuti iite marefu mafiibhi akatetepa anotambanudzwa nekutonhodzwa nekupfuura mhepo inopisa pamusoro pemafibhi paanodonha kubva pakufa.Iyo dandemutande inokonzeresa inounganidzwa kuita mipumburu yozoshandurwa kuita zvigadzirwa zvapera.

Spunlace (Hydrotentanglement)
Spunlace (inozivikanwawo sekuti hydroenanglement) inzira yekubatanidza kune yakanyorova kana yakaoma fibrous webs inogadzirwa nemakadhi, airlaying kana kunyorova-kuisa, mhedzisiro jira rakasungirirwa risiri rakarukwa.Kuita uku kunoshandisa majeti emvura akakwenenzverwa anopinda padandemutande, anorova bhandi rekutakura (kana kuti "waya" sepapepa rekutakura) uye kudzoka kumashure zvichiita kuti mafiibhi apinze.Machira eSpunlace asina kurukwa anoshandiswa mapfupi masitaple fibers, anonyanya kufarirwa ndeye viscose uye polyester staple fibers asi polypropylene nedonje zvinoshandiswa zvakare.Zvishandiso zvikuru zve spunlace zvinosanganisira zvekupukuta, kumeso pepa masks uye zvigadzirwa zvekurapa.

Spunlaid (Spunbond)
Spunlaid, inonziwo spunbond, nonwovens inogadzirwa mune imwe nzira inoenderera.MaFibers anorukwa obva aparadzirwa zvakananga muwebhu nema deflectors kana kuti anogona kunangana nemhepo.Iyi tekinoroji inotungamira nekukurumidza bhandi kumhanya, uye zvakachipa mutengo.

Spunmelt/SMS
Spunbond yakasanganiswa neyakanyunguduka-inoputika nonwovens, ichiita kuti iite chigadzirwa chakaiswa chinonzi SMS (spun-melt-spun).Melt-blown nonwovens ane madhayamita efiber akanyanya kunaka asi haasi machira akasimba.Machira eSMS, akagadzirwa zvachose kubva kuPP anodzivirira mvura uye akakwana kuti ashande semachira anoraswa.Melt-blown inowanzo shandiswa sefirita midhiya, ichikwanisa kutora zvimedu zvakanaka kwazvo.Spunlaid inosungirirwa ne resin kana thermally.

Wetlaid
Mukunyorova kwemvura, mafiber anosvika 12 mm kureba, kazhinji akasanganiswa neviscose kana pulp yehuni, anomiswa mumvura, achishandisa matangi makuru.Mushure mezvo mvura-fiber- kana mvura-pulp-dispersion inopomba uye inoramba ichiiswa pawaya yekugadzira.Mvura inosvetwa, yopepetwa uye yoshandiswazve.Kunze kwemafuta ekugadzira, girazi re ceramic uye kabhoni fibers zvinogona kugadziriswa.
