He aha Is "ʻAʻole i ulana ʻia" ?
Inā ua hoʻohana ʻoe i kahi pale maka, kahi ʻūpī pulu, a i ʻole kahi ʻeke kūʻai, ua hoʻopā ʻoelole i ulana ʻole ʻia. Akā eia ka mea ʻē aʻe: ʻaʻohe ona warp, ʻaʻohe weft, ʻaʻohe hilo, a ʻaʻohe ulana. Pono ka lole kuʻuna i ka milo a me ka ulana—ʻelua mau ʻanuʻu nui. Hōʻalo ka mea ulana ʻole i nā mea ʻelua. Hoʻokomo pololei ʻia nā olonā (a i ʻole ka palaki i hoʻoheheʻe ʻia) i loko o kahi pūnaewele, a laila hoʻopaʻa ʻia e ka wela, ka friction, a i ʻole nā mea hoʻopili kemika. I ka makahiki 2022, ua hana ʻo Kina i 8.29 miliona tons o ia mea—ʻoi aku ma mua o ka hapakolu o ka huina honua. ʻO ia ka ʻāpana ulu wikiwiki loa i nā lole, no ka mea ʻaʻole ia e hopohopo iki me nā "lole".
Meltblown: Ke Kānana Nui Loa
Hoʻoheheʻe ʻiaHoʻomaka me nā pellets polypropylene, i hoʻoheheʻe ʻia a hoʻopuka ʻia ma o nā nozzles liʻiliʻi. Hoʻolōʻihi nā pahū o ka ea wela 200-300°C i ka hoʻoheheʻe ʻana i loko o nā microfibers he 1-5 microns wale nō ka mānoanoa—ʻo kekahi he 0.5 microns ka lahilahi. (ʻO ka lauoho kanaka ma kahi o 70 microns.) Hana kēia mau olonā ultra-fine i kahi maze mānoanoa a wiliwili e hoʻopaʻa ana i nā bacteria, nā kulu, a me nā ʻāpana. ʻO ia ke kumu e pono ai ke hoʻoheheʻe ʻia ka papa waena o kahi pale maka ʻoki. ʻO ka hopu: holo ia ma 1-5 m/min wale nō, manaʻo palupalu, a he $3,500-5,500 ke kumukūʻai no kēlā me kēia ton—ʻelua a ʻekolu manawa ke kumukūʻai ma mua o nā mea ulana ʻole ʻē aʻe. No laila, ʻaʻole ʻoe e ʻike wale iā ia; ʻo ia mau ka meʻe huna i hoʻopaʻa ʻia ma waena o nā papa ikaika.
ʻO Spunbond: Ka Lio Hana
Hoʻoheheʻe pū ʻo Spunbond i ka polymer, akā hoʻopuka ia i nā filaments hoʻomau he 15-35 microns ka mānoanoa—ʻoi aku ka ʻoi aku ka paʻakikī a me ka ikaika. Hoʻolōʻihi ʻia e ka ea a kau ʻia ma luna o ke kāʻei neʻe, ua hoʻopaʻa ʻia ka pūnaewele me ka wela e nā wili wela. ʻO ka hopena: lole paʻa, pale i ka haehae e holo ana ma 50-500 m/min (a hiki i 1,000 m/min ma nā laina wikiwiki)—100 manawa wikiwiki ma mua o ka meltblown. Hoʻemi kēlā wikiwiki i nā kumukūʻai i $1,700-2,800 no kēlā me kēia tona. ʻO Spunbond kāu ʻeke kūʻai meaʻai, uhi mahiʻai, uhi lako, a me ka papa waho o nā lole pale. He mea kūʻai haʻahaʻa a paʻa, akā paʻakikī a plasticky—ʻaʻole kahi mea āu e makemake ai e holoi i kou maka.
SMS: ʻOi aku ka maikaʻi o ka hui pū ʻana
ʻAʻole koho pinepine nā huahana maoli i hoʻokahi kaʻina hana. Hoʻohui ka SMS-spunbond/meltblown/spunbond maʻamau i ka mea maikaʻi loa o nā mea ʻelua. Hoʻohana nā lole lapaʻau i ka spunbond o waho e ālai i nā wai, ka meltblown waena e hoʻopaʻa i nā ʻāpana, a me ka spunbond o loko no ka ʻoluʻolu. Hepale maka ʻoki kinoʻo ia hoʻi: pale ka papa waho i nā pīpī, hopu ka meltblown i nā maʻi, a omo ka papa o loko i ka makū. ʻOiai nā ʻūpī pulu he nui e hoʻopili i kahi papa spunlace palupalu me kahi kumu spunbond ikaika. Loaʻa nā nāwaliwali o nā kaʻina hana hoʻokahi; hāʻawi nā hui akamai i ka hana me ka ʻole o ka uhaki ʻana i ka panakō.
ʻAʻole i hana like ʻia nā mea ulana ʻole a pau
ʻAʻole i ulana ʻiaaia ma nā wahi āpau-nā pale maka, nā ʻūpā holoi, nā ʻeke, nā kānana, nā ʻaʻahu—akā ʻaʻole hiki i ka hapa nui o ka poʻe ke ʻike i ka meltblown mai ka spunbond. I kēia manawa ua ʻike ʻoe: pono ka kānana? E hele meltblown. Pono ka ikaika a me ke kumukūʻai haʻahaʻa? ʻO Spunbond kāu pane. A inā ʻike ʻoe i ka SMS, ke nānā nei ʻoe i kahi sanwika i hana pono ʻia. ʻO ka inoa "lole" like, ka hana like ʻole—a me kahi ʻokoʻa kumukūʻai ʻelima manawa. ʻO ka hoʻomaopopo ʻana i kēia mau ala ʻaʻole ia e lilo iā ʻoe i loea lole, akā e lilo ia i mea kūʻai akamai.
