Ka nānā 'ana i nā kumu nui e pili ana i nā waiwai kino spunbond nonwoven

I ke kaʻina hana o nā spunbonded nonwovens, hiki i nā mea like ʻole ke hoʻopilikia i nā waiwai kino o nā huahana.

ʻO ka nānā ʻana i nā kumu nui e pili ana i nā waiwai lole e kōkua pono i ka hoʻokele pono ʻana i nā kūlana kaʻina hana a loaʻa i nā PP spunbonded nonwovens maikaʻi me ka maikaʻi maikaʻi e kūpono i ka pono o nā mea kūʻai aku.

1.Polypropylene type: hehee helu helu a me ka mole kaumaha

ʻO nā ʻōlelo kikoʻī koʻikoʻi o nā mea polypropylene he paona molekala, hoʻohele kaumaha molecular, isotacticity, melt index a me ka ʻike lehu.
Aia nā mea hoʻolako polypropylene i ka upstream o ke kaulahao plastics, e hāʻawi ana i nā mea waiwai polypropylene ma nā māka like ʻole a me nā kikoʻī.
No ka hana ʻana i ka spunbond nonwoven, polypropylene molecular paona maʻamau ma ka laulā 100,000-250,000.Eia naʻe, ua hōʻike ʻia ʻoi aku ka maikaʻi o ka waiwai hoʻoheheʻe i ka wā e pili ana ke kaumaha o ka molekala ma kahi o 120000. ʻO ke kiʻekiʻe ka wikiwiki o ka wili ʻana i kēia pae.

ʻO ka helu heheʻe he ʻāpana e hōʻike ana i nā waiwai rheological o ka heheʻe.ʻO ka helu hoʻoheheʻe o ka ʻāpana PP no ka spunbond ma waena o 10 a me 50.

ʻO ka liʻiliʻi hoʻoheheʻe helu, ʻoi aku ka maikaʻi o ka fluidity, ʻoi aku ka liʻiliʻi o ka lākiō hoʻolālā, a ʻoi aku ka nui o ka nui o ka fiber ma lalo o ke ʻano o ka hoʻoheheʻe hoʻoheheʻe like mai ka spinneret, no laila hōʻike nā nonwovens i nā manaʻo lima paʻakikī.
I ka nui o ka helu hehee, emi ka viscosity o ka hehee, oi aku ka maikai o ka waiwai rheological, a emi iho ke ku e ana.Ma lalo o ke kūlana hana hoʻokahi, hoʻonui ka hoʻolālā ʻana.Me ka piʻi ʻana o ke degere orientation o macromolecules, e hoʻomaikaʻi ʻia ka ikaika haʻihaʻi o ka nonwoven, a e hoʻemi ʻia ka nui o ke kaula, a ʻoi aku ka palupalu o ka lole. .

2. Milo wela

ʻO ka hoʻonohonoho ʻana o ka mahana wili e pili ana i ka helu hehee o nā mea maka a me nā koi o nā waiwai kino o nā huahana.ʻO ke kiʻekiʻe o ka helu heheʻe e pono ai ke kiʻekiʻe o ka wela o ka wili, a ʻo ia hoʻi.Pili pono ka mahana wili me ka viscosity hehee.Ma muli o ka viscosity kiʻekiʻe o ka heheʻe, paʻakikī ke milo, ka hopena i ka haki, ʻoʻoleʻa a koʻikoʻi paha ka nui o nā yarn, e pili ana i ka maikaʻi o nā huahana.

No laila, i mea e hōʻemi ai i ka viscosity o ka heheʻe a hoʻomaikaʻi i nā waiwai rheological o ka heheʻe, hoʻonui ʻia ka mahana.Nui ka mana o ka wela o ka wili i ka hale a me nā waiwai o nā fiber.

Ke hoʻokiʻekiʻe ʻia ka mahana wili, ʻoi aku ka ikaika o ka haki, ʻoi aku ka liʻiliʻi o ka elongation haki, a ʻoi aku ka palupalu o ka lole.
I ka hoʻomaʻamaʻa, hoʻonohonoho maʻamau ka mahana wili 220-230 ℃.

3. Ka helu hoʻoluʻu

I ke kaʻina hana o nā spunbonded nonwovens, ʻoi aku ka ikaika o ka hoʻoluʻu ʻana o ka yarn i nā waiwai kino o nā spunbonded nonwovens.

Inā maloʻo mālie ka fiber, loaʻa iā ia ka hale aniani monoclinic paʻa, ʻaʻole kūpono i nā fibers e huki. ka uhaki ikaika a hoemi i ka elongation o ka lole spunbonded non-woven.Eia kekahi, pili pono ka mamao hoʻoluʻu o ka yarn i kona mau waiwai.I ka hana ʻana i nā lole spunbonded non-woven, ʻo ka mamao hoʻomaha ma waena o 50 cm a me 60 cm.

4. Nā Kūlana Drafting

ʻO ka pae orientation o ke kaulahao molekula i loko o ka filament kahi mea nui e pili ana i ka haki ʻana o ka elongation o ka monofilament.
Hiki ke hoʻomaikaʻi ʻia ka like ʻana a me ka haki ʻana o nā spunbonded nonwovens ma o ka hoʻonui ʻana i ka nui o ka ea suction.Eia nō naʻe, inā nui loa ka nui o ka ea suction, ua maʻalahi ke uhaʻi i ke kaula, a ʻoi aku ka paʻakikī o ka huki ʻana, ʻoi aku ka piha o ka orientation o ka polymer, a ʻoi aku ka kiʻekiʻe o ka crystallinity o ka polymer. ka hopena ikaika a me ka elongation i ka haʻihaʻi, a hoʻonui i ka brittleness, ka hopena i ka emi ʻana o ka ikaika a me ka elongation o ka lole i ulana ʻole ʻia.Hiki ke ʻike ʻia ka hoʻonui a me ka emi ʻana o ka ikaika a me ka elongation o nā spunbonded nonwovens me ka piʻi ʻana o ka nui o ka ea.I ka hana maoli, pono e hoʻoponopono ʻia ke kaʻina hana e like me nā pono a me ke kūlana maoli i mea e loaʻa ai nā huahana kiʻekiʻe.

5. Wela ʻolokaʻa wela

Ma hope o ka hoʻokumu ʻia ʻana o ka pūnaewele ma ke kaha kiʻi ʻana, ua wehe ʻia a pono e hoʻopaʻa ʻia e ka ʻōwili wela.ʻO ke kī ka mālama ʻana i ka mahana a me ke kaomi.ʻO ka hana o ka hoʻomehana ke hoʻomāmā a hoʻoheheʻe i ka fiber.ʻO ka hapa o nā mea palupalu a hoʻohui ʻia e hoʻoholo i nā waiwai kino o ka lole nonwoven PP spunbond.

Ke hoʻomaka haʻahaʻa loa ka mahana, ʻo kahi hapa liʻiliʻi wale nō me ke kaumaha molekala haʻahaʻa e palupalu a hoʻoheheʻe ʻia, ua hoʻopaʻa ʻia nā kaula liʻiliʻi ma lalo o ke kaomi. nui ka elongation, a palupalu ka lole akā hiki ke lilo i fuzz;

Ke piʻi aʻe ka wela o ka ʻōwili wela, piʻi ka nui o ka fiber i hoʻoheheʻe ʻia a hoʻoheheʻe ʻia, hoʻopaʻa ʻia ka pūnaewele fiber, ʻaʻole maʻalahi ke paheʻe.Piʻi ka ikaika haʻihaʻi o ka lole i ulana ʻole ʻia, a ʻoi aku ka nui o ka elongation.Eia kekahi, ma muli o ka pilina ikaika ma waena o nā fibers, piʻi iki ka elongation;

Ke piʻi nui ka mahana, hoʻomaka ka emi ʻana o ka ikaika o nā nonwovens, emi nui ka elongation, manaʻo ʻoe e lilo ka lole i mea paʻakikī a palupalu, a emi ka ikaika o ka waimaka. pono ka wela no ka palupalu a me ka heheʻe ʻana, no laila e hoʻohaʻahaʻa ka wela o ka ʻōwili ʻana.Pēlā nō, no nā mea mānoanoa, ʻoi aku ka kiʻekiʻe o ka wela wela.

6. Pumi owili wela

I ke kaʻina hana hoʻopaʻa ʻana o ka ʻōwili wela, ʻo ka hana o ke kaomi laina wili wela ka mea e hoʻopaʻa paʻa ai nā fibers i hoʻoheheʻe ʻia a hoʻoheheʻe ʻia, e hoʻonui i ka cohesion ma waena o nā fibers, a ʻaʻole maʻalahi ka paheʻe.

Ke haʻahaʻa haʻahaʻa ke kaomi laina wela, ʻilihune ka nui o ka fiber ma kahi e kaomi ai, ʻaʻole kiʻekiʻe ka wikiwiki o ka hoʻopaʻa ʻana i ka fiber, a ʻilihune ka hui pū ʻana ma waena o nā fibers.I kēia manawa, ʻano palupalu ka manaʻo lima o ka lole spunbonded non-woven, ʻoi aku ka nui o ka elongation ma ka haʻihaʻi, akā haʻahaʻa ka ikaika haʻihaʻi;
akā, ke kiʻekiʻe ke kaomi laina, ʻoi aku ka paʻakikī o ka lima o ka spunbonded non-woven fabric, a ʻoi aku ka haʻahaʻa o ka elongation ma ka haʻihaʻi akā ʻoi aku ka kiʻekiʻe o ka ikaika haki.ʻO ka hoʻonohonoho ʻana o ke kaomi ʻōwili wela e pili ana i ke kaumaha a me ka mānoanoa o nā lole i ulana ʻole ʻia.No ka hanaʻana i nā huahana i kūpono i nā koi o ka hana, pono e koho i ka'ōwili wela kūpono e like me nā pono.

Ma kahi huaʻōlelo, ʻo nā waiwai kino o nā lole i ulana ʻole ʻia ʻo ia ka hopena o ka launa pū ʻana o nā mea he nui. hoʻonohonoho i ka hana me ke kumu kikoʻī a hāʻawi i ka mea kūʻai aku i ka lole i ulana ʻole ʻia.

E like me 17 makahiki mea hana, Fuzhou Heng Hua New Material Co., Ltd.ua hilinaʻi hāʻawi lole e like me nā mea kūʻai 'koi.Ua hoʻokuʻu aku mākou i nā ʻāina like ʻole a me nā ʻāina a ua mahalo nui ʻia e nā mea hoʻohana.

Welina e kamaʻilio mai iā mākou a hoʻomaka i ka hui lōʻihi me Henghua Nonwoven!
