I ka ʻoihana hou, hoʻohana nui ʻia ka ʻenehana microporous metala a me nā huahana i nā kula he nui. I waena o lākou, ʻo nā huahana textile (ʻaʻahu a me nā textiles home) a me nā huahana palekana olakino e helu nui. Mai ka mea maka (nā ʻāpana kemika) a hiki i ka huahana i hoʻopau ʻia, pono e hele ka mea maka i nā kaʻina hana, e like me ka milo, ulana, pena, humuhumu, a me nā mea ʻē aʻe.

Ua kapa ʻia ʻo Spinneret. He ʻano mea me nā puka liʻiliʻi he nui o ka thimble e like me ka nozzle metala i hoʻohana ʻia no ka milo ʻana i ka fiber kemika. Hoʻoheheʻe ʻia ka mea i hoʻoheheʻe ʻia a hoʻoheheʻe ʻia paha, a laila kaomi ʻia i waho o nā lua e hana i ka filament, i hoʻopaʻa ʻia e ka condensation, evaporation a i ʻole ka hoʻoluʻu. Hana ʻia nā spinnerets me ke kila kila, akā pono ka hana rayon i ka platinum. ʻO ka nui a me ke ʻano o nā puka spinneret e hoʻoholo i ke ʻano ʻāpana kea o ke filament. Hana ʻia kēlā me kēia puka i hoʻokahi filament, a ʻo nā filament i hui ʻia e hana i ke kaula filament.

Me ka hoʻomohala ʻana o ka covid-19 i ka honua, a me ka laha ʻana ma ʻAmelika Hui Pū ʻIa a me ʻEulopa, ua loaʻa hou ka manaʻo o ka honua i nā huahana pale me ka ʻenehana kumu o ka lole nonwoven (spun bonded fabric / melt blown fabric). Mai ka maʻi maʻi i ka wā mua o ka maʻi ahulau a hiki i nā koi koʻikoʻi hou, ua hoʻomohala kā mākou huihehee puhispinnerets&wili i hoʻopaʻa ʻia&poʻomanaʻo make spinneret&laina hana lole lole ʻolee hoʻokō i ka noi mākeke, a loaʻa nā manaʻo maikaʻi mai ka mākeke.

Eia hou, ua loaʻa i kā mākou hui kahi māhele mākeke nui o nā spinnerets i hoʻohana ʻia i nā lole ulana kuʻuna, e like me nā ʻano spinnerets composite (ʻano mokupuni kai/sheath-coreʻano ʻano/ ʻāpana-pieʻano ʻano), a lawe ʻia aku i Asia Hikina Hema.
