Ka hopena o ka wela o ka pahu wela ma ka ʻoki ʻana, ka ikaika a me ke kala ʻana o ka nailona 6

Ma hope o nā makahiki o ka hoʻomaʻamaʻa hana, ua ʻike iki kā mākou hui, Highsun Synthetic Fiber Technologies Co., Ltd., i ka mana o ka wela o ka pahu wela ma ka crimping, ka ikaika a me ke kala ʻana o ka nylon 6.

1. Ka hopena ma ka nylon 6 crimping

Ma lalo o nā kūlana hana o ka hoʻolōʻihi ʻana o 1.239 mau manawa, D / Y o 2.10 a me ka wikiwiki o 700m / min, hoʻonui ka crimp shrinkage a me ka crimp stability me ka piʻi ʻana o ka mahana ma kekahi ʻano.ʻO kēia no ka mea ua hoʻomaikaʻi ʻia ka plasticity o ka fiber me ka piʻi ʻana o ka mahana, kahi e maʻalahi ai ka deform.No laila, ʻo ka nylon 6, he ʻano ʻano ʻē aʻe.Eia nō naʻe, ke haʻahaʻa loa ka mahana (ma lalo o 182 ℃), e haʻahaʻa ka nui o ka crimp a me ka paʻa o ka nalon 6.He palupalu a inelastic ka filament, i kapa ʻia ʻo ka pulupulu siliki.Ke kiʻekiʻe loa ka mahana (ʻoi aku ma mua o 196 ℃), e paʻa a ʻoʻoleʻa ka filament i hana ʻia.ʻO kēia ke kumu o ka maʻalili ʻana o nā fibrils ma lalo o ka wela kiʻekiʻe, ka hopena i nā fibrils i hoʻopaʻa ʻia a lilo i filament ʻoʻoleʻa.No laila ua hoʻemi nui ʻia ka emi ʻana o ka crimp.

2. Ka hopena ma ka nylon 6 ikaika

I ka wā o ke kaʻina hana, ua ʻike ʻia he hopena nui ka mahana o ka pahu wela i ka ikaika o ka nylon 6. Ma lalo o nā kūlana ʻenehana o ka hoʻouka ʻana i ka wikiwiki 630m / min, hoʻolōʻihi i ka lākiō 1.24 mau manawa a me D / Y 2.03, ke emi nei ka wiliwili. a ke emi iho nei ka untwisting haʻalulu me ka piʻi ʻana o ka mahana, ʻo ia ke kumu o ka palupalu ʻana o ka fiber i ka wela kiʻekiʻe.Ma kahi haʻahaʻa haʻahaʻa, piʻi ka ikaika me ka piʻi ʻana o ka mahana, akā e emi iho me ka piʻi hou ʻana o ka mahana (193 ℃).ʻO kēia ka mea ma muli o ka haʻahaʻa haʻahaʻa haʻahaʻa, hoʻonui ka hana o nā molekala fiber me ka piʻi ʻana o ka mahana, e hōʻemi ana i ke koʻikoʻi kūloko i ke kaʻina hana o ka thermal deformation, e maʻalahi i ka deform a hoʻonui i ka ikaika o ka filament.Eia naʻe, me ka hoʻonui hou ʻana o ka mahana, ua maʻalahi ka hoʻoneʻe ʻana i ka amorphous i ka fiber.Ke piʻi ka mahana i 196 ℃, paʻa a ʻoʻoleʻa nā fiber i hana ʻia me ka maikaʻi ʻole.Ma hope o nā hoʻokolohua he nui, ua ʻike ʻia ʻo ka nylon 6 ka ikaika kiʻekiʻe loa ke 187 ℃ ka mahana o ka pahu wela.ʻOiaʻiʻo, pono e hoʻoponopono ʻia kēia e like me ka wikiwiki o ka hoʻouka ʻana o ka nylon POY.Wahi a ka ʻike, ʻo ka haumia aila a me ka lepo e hoʻopili i ka pahu wela me ka emi ʻana o ka hoʻomaʻemaʻe ʻana o ka mīkini, e hōʻemi ana i ka pono hoʻomehana.

3. Ka hopena i ka naila 6 kala

Ke haʻahaʻa ka wela o ka pahu wela, ʻoi aku ka haʻahaʻa o ka naila 6, ʻoi aku ka maikaʻi o ke kala ʻana, a ʻoi aku ka hohonu o ke kala.ʻO ka mea'ē aʻe,ʻo ke kiʻekiʻe o ka wela o ka pahu wela ke kumu o ka'ōniʻoniʻo māmā a me ka lawe haʻahaʻa o ka nylon 6. No ka mea,ʻo ka mahana i hōʻikeʻia o ka mīkini i kekahi manawa e hoʻololi nuiʻia mai ka mahana i anaʻia, ke hoʻololiʻia ka mahana i 210 ° C i ka hana maoli, maikaʻi nā hiʻohiʻona a me nā kuhikuhi kino o ka nylon 6, akā maikaʻi ka hopena kala.
