He aha nā ʻano o nā mea ulana ʻole?
ʻAʻole i ulana ʻia
Ke hoʻohālikelike ʻia me nā ʻenehana nonwovens ʻē aʻe, loaʻa i ka airlaid ka mana kūʻokoʻa e waiho i nā fibers pōkole, a i ʻole 100% pulp fibers, a i ʻole nā ​​hui pū ʻana o ka pulp a me ka pōkole synthetic fibers, e hana i kahi pūnaewele homogeneous a mau.Hiki nō hoʻi ke hoʻohui i nā pauka superabsorbent a i ʻole nā ​​fibers e hana ai i nā pūnaewele hoʻoheheʻe loa.

Ea ma o ka hoʻopaʻa ʻana (Thermal Bonding)
Ma o ka hoʻopaʻa ʻana i ka ea he ʻano hoʻopaʻa wela e pili ana i ka hoʻopili ʻana o ka ea wela i ka ʻili o ka lole i ulana ʻole ʻia.I ka wā o ka hoʻopaʻa ʻana i ka ea, kahe ka ea wela ma nā lua i loko o kahi plenum ma luna o ka mea i ulana ʻole ʻia.

Meltblown
Hana ʻia nā mea ulana ʻole hoʻoheheʻe ʻia ma o ka hoʻoheheʻe ʻana i nā fiber polymer hehee ma o ka ʻupena milo a i ʻole ka make a hiki i 40 mau puka i kēlā me kēia ʻīniha e hana ai i nā fiber lahilahi lōʻihi i hohola ʻia a hoʻoluʻu ʻia e ka hele ʻana i ka ea wela ma luna o nā fiber ke hāʻule lākou mai ka make.ʻOhi ʻia ka pūnaewele hopena i loko o nā ʻōwili a hoʻololi ʻia i nā huahana i hoʻopau ʻia.

Spunlace (Hydrotentanglement)
ʻO Spunlace (ʻike ʻia ʻo hydroentanglement) he kaʻina hana hoʻopaʻa no nā pūnaewele pulupulu pulu a maloʻo paha i hana ʻia e ka carding, airlaying a i ʻole ka pulu pulu, ʻo ka mea i hoʻopaʻa ʻia he lole ʻole.Ke hoʻohana nei kēia kaʻina hana i nā pahu wai maikaʻi a me ke kiʻekiʻe e komo i ka pūnaewele, paʻi i ke kāʻei conveyor (a i ʻole "wire" e like me ka mea lawe pepa) a hoʻihoʻi i hope e hoʻopili ai nā fiber.Ua hoʻohana ʻia nā lole spunlace ʻaʻole i ulana ʻia i nā fiber staple pōkole, ʻo ka mea kaulana loa he viscose a me polyester staple fibers akā hoʻohana pū ʻia ka polypropylene a me ka pulupulu.ʻO nā noi nui no ka spunlace ka holoi ʻana, nā pale pale maka a me nā huahana olakino.

Spunlaid (Spunbond)
ʻO Spunlaid, i kapa ʻia ʻo spunbond, hana ʻia nā nonwovens i hoʻokahi kaʻina hana mau.Milo ʻia nā fibers a laila hoʻopuehu pololei ʻia i loko o ka pūnaewele e nā deflectors a hiki ke kuhikuhi ʻia me nā kahawai ea.Ke alakaʻi nei kēia ʻenehana i ka wikiwiki o ke kāʻei, a me nā kumukūʻai haʻahaʻa.

Spunmelt/SMS
Ua hui pū ʻia ʻo Spunbond me nā mea i ulana ʻole ʻia i hoʻoheheʻe ʻia, e hoʻohālikelike iā lākou i kahi huahana papa i kapa ʻia ʻo SMS (spun-melt-spun).ʻO nā mea i ulana ʻole i hoʻoheheʻe ʻia he mau anawaena fiber maikaʻi loa akā ʻaʻole ia he mau lole ikaika.ʻO nā lole SMS, i hana piha ʻia mai ka PP, he wai-repellent a maikaʻi hoʻi e lawelawe ma ke ʻano he lole hoʻopau.Hoʻohana pinepine ʻia ʻo Melt-blown ma ke ʻano he media kānana, hiki ke hopu i nā ʻāpana maikaʻi loa.Hoʻopaʻa ʻia ʻo Spunlaid e ka resin a i ʻole thermally.

Wetlaid
Ma ke kaʻina hana wetlaid, ua hoʻokuʻu ʻia i loko o ka wai nā fibers staple a hiki i 12 mm ka lōʻihi, i hui pinepine ʻia me ka viscose a i ʻole ka pulp lāʻau, me ka hoʻohana ʻana i nā pahu nui.Ma hope iho, pahū ʻia ka wai-fiber- a i ʻole ka wai-pulp-dispersion a waiho mau ʻia ma luna o kahi uwea hana.Hoʻopiʻia ka wai, kānana a hana hou.Ma waho aʻe o nā fiber synthetic, hiki ke hana ʻia ka glas ceramic a me nā fiber carbon.
