Ho latela phuputso e ncha e phatlalalitsoeng ho 《 Applied Materials Today 》, Thepa e ncha e entsoeng ka li-nanofibre tse nyane e ka nkela lintho tse ka bang kotsi tse sebelisoang ho lileiri le lihlahisoa tsa bohloeki kajeno.
Bangoli ba pampiri, ba tsoang Setsing sa Theknoloji sa India, ba re thepa ea bona e ncha e na le tšusumetso e fokolang tikolohong 'me e bolokehile ho feta eo batho ba e sebelisang kajeno.
Lilemong tse mashome a seng makae tse fetileng, li-diaper tse lahlehang, li-tampon le lihlahisoa tse ling tsa bohloeki li sebelisitse li-absorbent resin (SAPs) e le li-absorber. Lintho tsena li ka monya boima ba tsona ka makhetlo a 'maloa ka metsi;Leleiri le tloaelehileng le ka monya maro a ’mele ka makhetlo a 30 boima ba lona.Empa thepa ha e fokotsehe: tlas'a maemo a loketseng, leleire le ka nka lilemo tse 500 ho theola.Li-SAP le tsona li ka baka mathata a bophelo bo botle joalo ka toxic shock syndrome, 'me li ne li thibetsoe ho tloha ho li-tampon ka bo-1980.
Ntho e ncha e entsoeng ka electrospun cellulose acetate nanofibers ha e na e 'ngoe ea litšitiso tsena.Thutong ea bona, sehlopha sa lipatlisiso se ile sa hlahloba boitsebiso boo, boo ba lumelang hore bo ka nka sebaka sa SAPs tse sebelisoang hona joale lihlahisoa tsa bohloeki ba basali.
"Ho bohlokoa ho theha mekhoa e meng e sireletsehileng ho lihlahisoa tse fumanehang khoebong, tse ka bakang toxic shock syndrome le matšoao a mang," Ngaka Chandra Sharma, sengoli se tsamaisanang le pampiri.Re fana ka maikutlo a hore ho tlosoe lintho tse kotsi tse sebelisoang lihlahisoa tse fumanehang hona joale tsa khoebo le li-resin tsa superabsorbent tse se nang biodegradable motheong oa ho se fetole ts'ebetso ea sehlahisoa kapa ho ntlafatsa ho monya le boiketlo ba metsi.
Li-nanofibers ke likhoele tse telele le tse tšesaane tse hlahisoang ke electrospinning.Ka lebaka la sebaka sa bona se seholo, bafuputsi ba lumela hore ba monyela ho feta lisebelisoa tse teng.Thepa e sebelisoang ho li-tampons tse fumanehang khoebong e entsoe ka likhoele tse sephara, tse tlanngoeng ka li-micron tse 30 ka morao.Li-nanofiber, ka lehlakoreng le leng, li tenya ka li-nanometer tse 150, tse tšesaane ka makhetlo a 200 ho feta thepa ea hajoale.Lisebelisoa li phutholohile ho feta tse sebelisoang lihlahisoa tse teng 'me li siea masala a fokolang ka mor'a tšebeliso.
Thepa ea nanofiber e boetse e na le porous (ho feta 90%) khahlanong le e tloaelehileng (80%), kahoo e monyela haholoanyane.Ntlha e 'ngoe e ka etsoa: ho sebelisa liteko tsa saline le tsa maiketsetso tsa moroto, likhoele tsa masela tsa electrostatic li monya ho feta lihlahisoa tse fumanehang khoebong.Ba boetse ba lekola mefuta e 'meli ea lisebelisoa tsa nanofibre ka li-SAP, mme liphetho li bonts'a hore nanofibre feela e sebetsa betere.
"Liphetho tsa rona li bontša hore li-electrostatic textile nanofibers li sebetsa hantle ho feta lihlahisoa tsa bohloeki tse fumanehang khoebong mabapi le ho monya metsi le boiketlo, 'me re lumela hore ke mokhethoa ea molemo oa ho nkela lintho tse kotsi tse sebelisoang hona joale," Dr. Sharma o itse."Re tšepa ho ba le phello e ntle bophelong ba batho le tikolohong ka tšebeliso e sireletsehileng le ho lahla lihlahisoa tsa bohloeki.
