Ndeapi marudzi emhando dzisina kurukwa?
Zvisina Kurukwa Zvakaiswa Nemhepo
Zvichienzaniswa nedzimwe nzira dzisina kurukwa, airlaid ine kugona kwakasiyana kwekuisa pasi shinda pfupi, ingava 100% pulp fibers, kana musanganiswa we pulp neshinda dzakagadzirwa pfupi, kuti igadzire tambo yakafanana uye inoramba iripo. Zvinokwanisikawo kusanganisa nehupfu hunowedzera kunyungudutsa kana shinda nokudaro zvichigadzira tambo dzinonyungudutsa zvakanyanya.

Kubatana Kwemhepo Nemhepo (Kubatana Kwekupisa)
Kubatanidza mweya nemhepo imhando yekubatanidza kwemhepo kunosanganisira kuisa mweya unopisa pamusoro pejira risina kurukwa. Munguva yekubatanidza mweya nemhepo, mweya unopisa unoyerera nemumaburi ari pamusoro pechinhu chisina kurukwa.

Kunyunguduka
Micheka isina kucheneswa inonyungudika inogadzirwa nekuburitsa fibers dzepolymer dzakanyungudika kuburikidza ne spin net kana die ine maburi anosvika makumi mana pa inchi imwe neimwe kuti igadzire fibers dzakatetepa refu dzinotambanudzwa uye dzinotonhodzwa nekupfuudza mhepo inopisa pamusoro pefibers padzinodonha kubva pa die. Dandemutande rinobuda rinounganidzwa kuita rolls uye rinozoshandurwa kuita zvigadzirwa zvakapedzwa.

Spunlace (Hydrotentanglement)
Spunlace (inozivikanwawo sehydroentanglement) inzira yekubatanidza mawebhu e fibrous akanyorova kana akaoma akagadzirwa ne carding, airlaying kana wet-laying, jira rakabatanidzwa rinobuda riri risina kurukwa. Maitiro aya anoshandisa mvura ine simba rakawanda, inopinda muwebhu, yorova conveyor belt (kana "waya" semuchina wekugadzira mapepa) yodzokera kumashure zvichiita kuti mafirita apindire. Spunlace machira asina kurukwa anoshandiswa mapfupi staple fibers, anonyanya kufarirwa ndiwo viscose ne polyester staple fibers asi polypropylene nedonje zvinoshandiswawo. Mashandisirwo makuru e spunlace anosanganisira ma wipes, facial sheet masks uye mishonga yekurapa.

Spunlaid (Spunbond)
Mashinda asina kuchekwa, anonziwo spunbond, anogadzirwa nenzira imwe chete inoenderera mberi. Mashinda anokoshwa uye anobva aparadzirwa zvakananga muwebhu nevanotenderedza kana kuti anogona kutungamirirwa nemhepo. Iyi nzira inoita kuti bhandi rikurumidze kumhanya, uye mitengo yakaderera.

Kunyunguduka/SMS
Spunbond yakabatanidzwa ne nonwovens dzakanyungudutswa, zvichiita kuti dziite chigadzirwa chakagadzirwa nejira chinonzi SMS (spun-melt-spun). Nonwovens dzakanyungudutswa dzine dhayamita dzakatetepa zvikuru asi hadzisi machira akasimba. Machira eSMS, akagadzirwa kubva kuPP zvachose haapindi mvura uye akanaka zvakakwana kuti ashande semachira anoraswa. Melt-blown inowanzo shandiswa se filter media, ichikwanisa kubata zvidimbu zvitete kwazvo. Spunlaid inosungirirwa ne resin kana kuti ne thermally.

Wettlaid
Mukuita kwe wetlaid, ma staple fibers ane hurefu hwe 12 mm fiber, anowanzo sanganiswa ne viscose kana pulp yehuni, anosungirirwa mumvura, achishandisa matangi makuru. Mushure mezvo, water-fiber-kana water-pulp-dispersion inopombwa uye inogara ichiiswa pawaya inoumba. Mvura inosvetwa, inosefetwa uye inodzokororwazve. Kunze kwemafiber ekugadzira, magirazi e ceramic uye carbon fibers anogona kugadziriswa.
