ʻO ke ʻano o ka huaʻōlelo nonwoven ʻaʻole ia he "ulana" a ʻaʻole hoʻi he "knit", akā ʻoi aku ka nui o ka lole. ʻO ka non-woven kahi ʻano lole i hana pololei ʻia mai nā olonā ma o ka hoʻopaʻa ʻana a i ʻole ka interlocking a i ʻole nā mea ʻelua. ʻAʻohe ona ʻano geometric i hoʻonohonoho ʻia, akā ʻo ia ka hopena o ka pilina ma waena o hoʻokahi olonā a me kekahi. ʻAʻole paha e maopopo nā aʻa maoli o nā nonwovens akā ua hoʻokumu ʻia ka huaʻōlelo "nonwoven fabrics" i ka makahiki 1942 a ua hana ʻia ma ʻAmelika Hui Pū ʻIa.
Hana ʻia nā lole ulana ʻole ma nā ʻano nui ʻelua: ua felted ʻia a i ʻole ua hoʻopaʻa ʻia. Hana ʻia ka lole ulana ʻole i felted ʻia ma ke kau ʻana i nā pepa lahilahi, a laila e hoʻopili ana i ka wela, ka makū a me ke kaomi e hoʻēmi a hoʻopaʻa i nā olonā i loko o kahi lole mānoanoa i ʻole e haehae a mae paha. Eia hou, aia he 3 mau ʻano nui o ka hana ʻana i nā lole ulana ʻole i hoʻopaʻa ʻia: Dry Laid, Wet Laid & Direct Spun. I ke kaʻina hana hana lole ulana ʻole Dry Laid, ua kau ʻia kahi pūnaewele o nā olonā i loko o kahi pahu a ua hoʻokomo ʻia ka ea wela e hoʻopaʻa i nā olonā. I ke kaʻina hana hana lole ulana ʻole Wet-Laid, ua hui pū ʻia kahi pūnaewele o nā olonā me kahi mea hoʻoheheʻe palupalu e hoʻokuʻu ana i kahi mea like me ke kāpili e hoʻopaʻa i nā olonā a laila ua kau ʻia ka pūnaewele e maloʻo. I ke kaʻina hana hana lole ulana ʻole Direct Spun, ua milo ʻia nā olonā ma luna o kahi kāʻei conveyor a ua pīpī ʻia nā kāpili ma luna o nā olonā, a laila kaomi ʻia e hoʻopaʻa. (I ka hihia o nā olonā thermoplastic, ʻaʻole pono ke kāpili.)
Nā Huahana ʻAʻole i Uhi ʻia
Ma nā wahi āu e noho ai a kū paha i kēia manawa, e nānā wale a puni a ʻike ʻoe ma ka liʻiliʻi he hoʻokahi lole ulana ʻole. Loaʻa nā lole ulana ʻole i nā mākeke like ʻole e like me ka lāʻau lapaʻau, nā lole, nā kaʻa, ka kānana, ke kūkulu ʻana, nā geotextiles a me ka pale. I kēlā me kēia lā, ke hoʻonui nei ka hoʻohana ʻana i ka lole ulana ʻole a me ka ʻole o lākou, e lilo ko kākou ola i mea paʻakikī ke hoʻomaopopo. ʻO ke kumu, aia he 2 ʻano lole ulana ʻole: Paʻa a me ka hoʻolei ʻana. Ma kahi o 60% o ka lole ulana ʻole he paʻa a ʻo ke koena he 40% ka hoʻolei ʻana.
He mau hana hou i ka ʻoihana ulana ʻole:
Ke hoʻonui mau ʻia nei ka ʻoihana ulana ʻole me nā hana hou e koi ana i ka manawa a kōkua pū kēia i ka holomua ʻana o nā ʻoihana.
ʻO Surfaceskins (Nonwovens Innovation & Research Institute- NIRI): He mau pale paʻi puka antibacterial a me nā lima huki i hana ʻia e pepehi i nā germs a me nā bacteria i waiho ʻia i loko o nā kekona koʻikoʻi, ma waena o kekahi mea hoʻohana a me ka mea aʻe e hele ana ma ka puka. No laila kōkua ia i ka pale ʻana i ka laha ʻana o nā germs a me nā bacteria i waena o nā mea hoʻohana.
ʻO Reicofil 5 (Reifenhäuser Reicofil GmbH & Co. KG): Hāʻawi kēia ʻenehana i ka ʻenehana laina huahua loa, hilinaʻi a me ka pono e hōʻemi ana i nā ʻāpana paʻakikī ma ka 90 pakeneka; hoʻonui i ka hana a hiki i ka 1200 m/min; hoʻomaʻalahi i ka manawa mālama; hoʻemi i ka hoʻohana ʻana i ka ikehu.
ʻO Remodelling™ Compound Hernia Patch (Shanghai Pine & Power Biotech): He ʻāpana nano-scale electro-spun ia he mea hoʻopili biological absorbable kūpono loa ke kumukūʻai a lawelawe ia ma ke ʻano he wahi ulu no nā cell hou, a i ka hopena biodegrading; e hōʻemi ana i ka nui o nā pilikia ma hope o ke ʻoki ʻana.
Koi Honua:
Ke mālama nei i kahi manawa ulu mau loa i nā makahiki 50 i hala iho nei, hiki i ka lole ulana ʻole ke lilo i ʻāpana puka aʻe o ka ʻoihana lole honua me ka loaʻa kālā kiʻekiʻe aʻe ma mua o nā huahana lole ʻē aʻe. Ke alakaʻi ʻia nei ka mākeke honua o ka lole ulana ʻole e Kina me kahi māhele mākeke ma kahi o 35%, ukali ʻia e ʻEulopa me kahi māhele mākeke ma kahi o 25%. ʻO nā mea pāʻani alakaʻi i kēia ʻoihana ʻo AVINTIV, Freudenberg, DuPont a me Ahlstrom, kahi ʻo AVINTIV ka mea hana nui loa, me ka māhele mākeke hana ma kahi o 7%.
I kēia mau lā iho nei, me ka piʻi ʻana o nā hihia COVID-19, ua piʻi ka noi no nā huahana hoʻomaʻemaʻe a me nā huahana lapaʻau i hana ʻia me nā lole i ulana ʻole ʻia (e like me: nā pāpale ʻokiʻoki, nā pale maka ʻokiʻoki, PPE, ʻapena lapaʻau, nā uhi kāmaʻa, a pēlā aku) a hiki i ka 10x a i ka 30x ma nā ʻāina like ʻole.
Wahi a kahi hōʻike a ka hale kūʻai noiʻi mākeke nui loa o ka honua ʻo "Research & Markets", ua helu ʻia ka mākeke lole nonwoven honua no $44.37 biliona i ka makahiki 2017 a ua manaʻo ʻia e hōʻea i $98.78 biliona ma ka makahiki 2026, e ulu ana ma kahi CAGR o 9.3% i ka wā wānana. Ua manaʻo ʻia hoʻi e ulu ka mākeke lole nonwoven paʻa me kahi helu CAGR kiʻekiʻe.
No ke aha i ulana ʻole ʻia ai?
He mea hou, hana noʻeau, versatile, ʻenehana kiʻekiʻe, hiki ke hoʻololi, pono a palaho nā mea ulana ʻole. Hana pololei ʻia kēia ʻano lole mai nā olonā. No laila, ʻaʻohe pono o nā ʻanuʻu hoʻomākaukau olonā. He pōkole a maʻalahi ke kaʻina hana. Ma kahi e hana ai i 5,00,000 mika o ka lole ulana, pono ia ma kahi o 6 mahina (2 mahina no ka hoʻomākaukau olonā, 3 mahina no ka ulana ʻana ma 50 mau loom, 1 mahina no ka hoʻopau ʻana a me ka nānā ʻana), he 2 mahina wale nō e hana ai i ka nui like o ka lole ulana ʻole. No laila, kahi o 1 mete/minuke ka wikiwiki o ka hana ʻana o ka lole ulana a he 2 mika/minuke ka wikiwiki o ka hana ʻana o ka lole ulana, akā he 100 mika/minuke ka wikiwiki o ka hana ʻana o ka lole ulana ʻole. Eia kekahi, haʻahaʻa ke kumukūʻai hana. Eia kekahi, hōʻike ka lole ulana ʻole i nā waiwai kikoʻī e like me ka ikaika kiʻekiʻe, ka hanu ʻana, ka absorbency, ka lōʻihi, ka māmā, ka lohi o ke ahi, ka hoʻolei ʻana a pēlā aku. Ma muli o kēia mau hiʻohiʻona kupaianaha a pau, ke neʻe nei ka ʻāpana lole i nā lole ulana ʻole.
Hopena:
Ua ʻōlelo pinepine ʻia ka lole i ulana ʻole ʻia ʻo ia ka wā e hiki mai ana o ka ʻoihana lole no ka mea ke piʻi nei ko lākou koi honua a me ka versatility.
