He aha nā ʻano mea laminated nonwoven no nā kaʻa?

Laminated nonwoven mea

ʻO ka uhi ʻana he kaʻina hana kahi e hoʻoheheʻe ʻia ai ka polymer ma luna o kahi substrate ma o ka mīkini uhi, a laila maloʻo e hana i kahi kiʻiʻoniʻoni pale ma ka ʻili o ka substrate. ʻO nā kiʻiʻoniʻoni polymer kiʻekiʻe he polyethylene, polypropylene, a i ʻole polyester, a ua māhele ʻia i nā kiʻiʻoniʻoni wai a me nā kiʻiʻoniʻoni ʻaila e pili ana i ko lākou ʻano. Hoʻoheheʻe ka ʻenehana hoʻoheheʻe wai i nā polymers kiʻekiʻe i ka wai, a laila e uhi i ka mea hoʻoheheʻe ma ka ʻili o ka lole, a ma hope e hana i kahi papa pale substrate ma o ka maloʻo infrared a i ʻole ka maloʻo maoli. ʻO ka mea hoʻoheheʻe i hoʻohana ʻia i ka ʻenehana uhi ʻaila ʻo ia ka resin photosensitive UV, hiki ke hoʻomaloʻo wale ʻia e ka radiation ultraviolet. Hiki ke hoʻohana ʻia no ka manawa lōʻihi ma nā ʻano kaiaola a i ʻole physicochemical e like me ka infrared, ultraviolet, laser, makani, hau, ua, hau, acid a me ka alkali.

Hoʻomākaukau ʻia nā mea i ulana ʻole ʻia e ka uhi ʻana i nā mea i ulana ʻole ʻia me nā mea hoʻoheheʻe polymer kiʻekiʻe a i ʻole nā ​​​​mea hoʻoheheʻe, a hiki ke ʻano o ka uhi hoʻokahi a i ʻole ka papalua pālua, e like me ka mea i hōʻike ʻia ma ka Figure 1 a me ka Figure 2. Hiki i ka papa hoʻopili ke hāʻawi i kahi ikaika a hoʻopaʻa i nā ili o ka substrate, e hoʻopau i ka paheʻe like ʻana ma waena o nā waiwai, a hoʻomaikaʻi i ka paheʻe mechanical. I ka manawa like, hiki i ka hoʻohana ʻana i nā hiʻohiʻona o ka papa uhi hiki ke hāʻawi i ka waiwai me ka wai a me nā waiwai repellent aila.

Nā ʻano mea i ulana ʻole ʻia

I kēia manawa, ʻo nā substrate i hoʻohana ʻia no ka hoʻohana nui ʻana i nā mea laminated nonwoven ka nui o nā mea i ulana ʻole ʻia i ka nila a me nā mea spunbond nonwoven, me ka hoʻohana ʻana i nā mea ʻaʻole i ulana ʻia hydroentangled.

ʻO nā mea ʻaʻole i ulana ʻia i ke kui laminated

ʻO nā mea i ulana ʻole ʻia i ke kui i haku ʻia me nā fiber me kahi ʻano mesh ʻekolu-dimensional, kahi e hāʻawi ai i nā lole nonwoven i hoʻopaʻa ʻia i ka nila i ka permeability maikaʻi a me ka hana kānana. I ka wā o ke kaʻina hana hoʻoheheʻe ʻana, hoʻopaʻa pinepine ka nila i ka pūnaewele fiber, e koi ana i nā fibers ma ka ʻili a ma ka ʻāina i loko o ka pūnaewele. Hoʻopili ʻia ka pūnaewele fluffy mua, e hāʻawi ana i ka lole i ulana ʻole ʻia i ke kui i nā waiwai mechanical maikaʻi loa. ʻO ka uhi ʻana i ka ʻili o nā mea i ulana ʻole ʻia me kahi ʻāpana o ka kiʻiʻoniʻoni polymer kiʻekiʻe a me kahi papa kiʻiʻoniʻoni i hoʻoheheʻe ʻia e hiki ke komo i loko o ka loko o ka mea, e hoʻomaikaʻi i ka ikaika composite o ka uhi kiʻiʻoniʻoni [5]. No ka mea, ʻelua mau mea i hoʻopaʻa ʻia i ka nila fiber, ʻoi aku ka paʻa o ke kiʻiʻoniʻoni hoʻoheheʻe ʻia me nā fibers, e ʻoi aku ka paʻa o ke ʻano.

Laminated spunbond mea i ulana ole ia

He mau waiwai maikaʻi loa nā lole Spunbond nonwoven e like me ka ikaika kiʻekiʻe, ka ʻili maʻemaʻe, ka lima palupalu, a me ke kūpaʻa ʻana i ke kulou a me ka ʻaʻahu, a hoʻohana nui ʻia i nā lole kaʻa. Hoʻopaʻa paʻa ʻia nā ʻili o loko o nā mea spunbond nonwoven ma nā wahi ʻōwili, a hoʻopuʻi ʻia kahi papa o ka polymer kiʻekiʻe ma ka ʻili o ka mea. He mea maʻalahi ke kiʻiʻoniʻoni hoʻoheheʻe ʻia me nā fibers a me nā wahi ʻōwili o ka mea spunbond, e hoʻomaikaʻi ana i ka hana piha o ka laminated spunbond nonwoven material.

Laminated hydroentangled nonwoven mea

ʻO ke kaʻina hana o ka hydroentangled nonwoven material, ʻo ia ka hopena o ka jet wai ultra-fine kiʻekiʻe i ka pūnaewele fiber, e hoʻopili ai nā fibers i loko o ka pūnaewele fiber i kekahi i kekahi a hana i kahi mea i ulana ʻole ʻia ma lalo o ka hopena o ka jet wai. Loaʻa i nā mea i ulana ʻole ʻia ka wai me ka palupalu a me ka elasticity. Ke hoʻohālikelike ʻia me nā mea i ulana ʻole ʻia i ka nila, ʻoi aku ka nāwaliwali o ka ikaika o ka hopena o ka nila wai, ka hopena o ka entanglement haʻahaʻa ma waena o nā fibers i loko o ka nila wai i kuʻi ʻia i nā mea nonwoven, e hāʻawi ana i ka hanu maikaʻi. Ma ka hoʻohana ʻana i ka ʻenehana uhi kiʻiʻoniʻoni, ua uhi ʻia kahi papa o ka kiʻiʻoniʻoni polymer kiʻekiʻe ma luna o ka ʻili o ka wai jet nonwoven material, ʻaʻole ia e hāʻawi wale i ka hana pale kiʻi maikaʻi loa, akā loaʻa nō hoʻi ka maʻalahi a me ka elasticity tensile.

Dongguan Liansheng Non ulana 'enehana Co., Ltd.ua hoʻokumu ʻia ma Mei 2020. He ʻoihana hana lole lole ʻaʻole i ulana nui ʻia e hoʻohui i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, a me ke kūʻai aku. Hiki iā ia ke hana i nā kala like ʻole o ka PP spunbond non-woven fabrics me ka laulā o lalo o 3.2 mika mai 9 grams a 300 grams.
