Hiki ke hoʻohana i ka lāʻau lapaʻau hou nā mea hoʻohui hou

Ua hoʻomohala nā mea noiʻi ma ke Kulanui o Georgia i kahi mea hou nona nā waiwai kūpono no nā mea lapaʻau e like me nā masks a me nā bandage. ʻOi aku ka maikaʻi o ke kaiapuni ma mua o nā mea i hoʻohana ʻia i kēia manawa.
Ke hoʻohana nei i nā nonwovens (nā lole i hana ʻia e ka hui ʻana i nā fibers me ka ʻole o ka ulana ʻana a i ʻole ka ulana ʻana), ua hiki i ka hui i alakaʻi ʻia e Gajanan Bhat ke hana i nā mea hoʻonaninani maʻalahi, breathable a me ka absorbent i kūpono no nā mea lapaʻau. ʻO ka hoʻokomo ʻia ʻana o ka pulupulu e ʻoluʻolu i ka ʻili (he mea nui no nā kumu lapaʻau) a maʻalahi hoʻi i ka compost, ʻoi aku ka maikaʻi o ke kaiapuni ma mua o nā huahana like i kēia manawa ma ka mākeke.
I loko o kāna hale hana ma ka Northern Riverbend Research Laboratory, ua hōʻike ʻo Polofesa Gajanan Bhat i ke ʻano o ka hiki ke hoʻopili ʻia a hoʻohana ʻia i nā lole lapaʻau. (Na Andrew Davis Tucker/Ke Kulanui o Georgia)
Me ke kālā mai ka USDA, ua hoʻāʻo nā mea noiʻi i nā hui like ʻole o ka pulupulu a me nā nonwovens, a me nā mea i ulana ʻole ʻia, no nā waiwai e like me ka breathability, ka wai absorption a me ka stretchability. Hana maikaʻi ʻia nā lole hana i nā hoʻāʻo, hāʻawi i ka hanu maikaʻi, ʻoi aku ka nui o ka wai a me ka hoʻihoʻi tensile maikaʻi, ʻo ia hoʻi hiki iā lākou ke pale i ka hoʻohana pinepine ʻana.
Ke ulu nei ka noi no nā nonwovens i nā makahiki i hala iho nei, a ke manaʻo ʻia nei ke kumukūʻai mākeke e hōʻea i US $ 77 biliona ma 2027, e like me ka hōʻike mai Acumen Research and Consulting. Hoʻohana nui ʻia nā nonwovens i nā huahana hale e like me nā diapers, nā mea hoʻomaʻemaʻe wahine, a me nā kānana ea a me ka wai. He wai wai lākou, maʻalahi, hanu, a me ko lākou hiki ke kānana i ka ea e kūpono iā lākou no ka hoʻohana olakino.
"ʻO kekahi o kēia mau huahana i hoʻohana ʻia no nā kumu biomedical, e like me nā patches a me nā bandage, pono e hoʻolōʻihi ʻia a hoʻihoʻi hou ʻia ma hope o ka hoʻopololei ʻana. Akā, no ka mea e pili ana lākou i ke kino, hiki i ka hoʻohana ʻana i ka pulupulu ke pono maoli, wahi a ka Family and Consumer College. Wahi a nā lawelawe ʻo Barth, ka luna o ka Department of Textiles, Merchandising and Interior Design, nāna i kākau i ka pepa. Hoʻomana Mohameka.
ʻOiai ʻaʻole ʻo ka pulupulu e like me ka lole i ulana ʻole ʻia, ʻoi aku ka ʻoi aʻe o ka ʻoluʻolu a me ka palupalu, ʻoi aku ka ʻoluʻolu o ke komo ʻana. ʻO ka pulupulu kekahi mea kanu nui ma Georgia a he ʻāpana koʻikoʻi o ka hoʻokele waiwai o ka mokuʻāina. Ke ʻimi mau nei ka USDA i nā mea hoʻohana hou no ka pulupulu, a ua ʻōlelo ʻo Barth iā lākou e "hui i nā mea i ulana ʻole ʻia me ka pulupulu e hana i kahi mea kiʻekiʻe i ka ʻiʻo pulupulu a me ka laulima."
Hoʻāʻo ʻo Polofesa Gajanan Bhat i nā mea ulana ʻole hiki ke hoʻohana ʻia me ka hoʻohana ʻana i ka mea hoʻāʻo permeability i kāna hale hana ma Riverbend North Research Laboratories. (Na Andrew Davis Tucker/Ke Kulanui o Georgia)
Manaʻo ʻo Barth, ka mea loea i nā mea ulana ʻole, hiki i nā mea i loaʻa ke hoʻopaʻa i nā waiwai i makemake ʻia o nā mea ulana ʻole ʻoiai ʻoi aku ka maʻalahi o ka lawelawe ʻana a me ka compostable.
No ka hoʻāʻo ʻana i nā waiwai o nā composites, ua hui pū ʻo Bhat, Sikdar a me Islam i ka pulupulu me ʻelua ʻano nonwovens: spunbond a me meltblown. Loaʻa i nā mea ulana ʻole ʻo Spunbond nā fiber ʻoi aku ka paʻakikī a ʻoi aku ka maʻalahi, ʻoiai ʻo nā nonwoven hoʻoheheʻe hoʻoheheʻe ʻia he mau fiber ʻoi aku ka maikaʻi a ʻoi aku ka maikaʻi o nā waiwai kānana.
"ʻO ka manaʻo, 'He aha ka hui e hāʻawi iā mākou i nā hopena maikaʻi?'" wahi a Butt. "Makemake ʻoe e loaʻa i kahi hoʻihoʻi hou ʻana, akā e hanu pū kekahi a loaʻa kekahi mana wicking."
Ua hoʻomākaukau ka hui noiʻi i nā mea ulana ʻole o nā ʻano mānoanoa like ʻole a ua hui pū me hoʻokahi a ʻelua paha ʻāpana o ka lole pulupulu, i loaʻa ai he 13 mau ʻano no ka hoʻāʻo ʻana.
Ua hōʻike ʻia nā hoʻāʻo ʻana ua hoʻomaikaʻi ka mea hoʻohuihui i ka hoʻomaʻamaʻa wai i hoʻohālikelike ʻia me ka mea i ulana ʻole ʻia, ʻoiai e mālama ana i ka hanu maikaʻi. Hoʻopili nā mea hoʻohuihui i 3-10 mau manawa ʻoi aku ka nui o ka wai ma mua o nā lole lole ʻole. Mālama pū ka composite i ka hiki o nā mea ulana ʻole ke hoʻōla mai ka hoʻopololei ʻana, e ʻae iā lākou e hoʻokipa i nā neʻe kūlohelohe me ka ʻole o ka deformation.
Hiki ke hoʻohana i ka pulupulu ʻoi aku ka maikaʻi o ke kaʻina hana o ka hana ʻana i ka pulupulu ʻano haʻahaʻa a i kekahi manawa ʻo ka ʻōpala a i ʻole ka pulupulu hana hou ʻia mai ka hana ʻana i nā huahana e like me nā T-shirts a me nā pale moe, wahi a Barth, ke kaukaʻi o nā fibers and textiles ma Georgia Athletic Association. No laila, ʻoi aku ka maikaʻi o ka hopena o ka huahana a ʻoi aku ka maikaʻi o ka hana.
Ua paʻi ʻia ke aʻo ʻana ma ka puke pai Industrial Textiles. ʻO nā mea kākau pū ʻo Doug Hinchliffe lāua ʻo Brian Condon o ka USDA Southern Regional Research Center.
