ʻAʻole i ulana ʻia ka polypropylene vs polyester

ʻAʻole nā ​​lole i ulana ʻia ʻaʻole nā ​​lole i ulana ʻia, akā ua haku ʻia me ka hoʻonohonoho ʻana a i ʻole ka hoʻonohonoho fiber random, no laila ua kapa ʻia lākou he lole ʻaʻole i ulana ʻia. Ma muli o nā ʻano mea like ʻole a me nā kaʻina hana, hiki ke hoʻokaʻawale ʻia nā lole i ulana ʻole ʻia i nā ʻano he nui, e like menā lole i ulana ʻole polyester, polypropylene lole i ulana ole ia, etc.

Nīnau pinepine ka poʻe kūʻai e pili ana i ka ʻokoʻa ma waena o ka lole polyester non-woven, polypropylene non-woven fabric, polypropylene fiber, a me ka polyester i ka wā e kūkākūkā ai i nā huahana lole ʻole. Aia ma lalo ka papa inoa o ko lākou mau ʻokoʻa.

PET lole i ulana ʻole ʻia

ʻO ka PET spunbond filament non-woven fabric he ʻano o ka wai repellent non-woven fabric, a ʻokoʻa kāna hana hoʻohemo wai ma muli o ke kaumaha o ka lole. ʻOi aku ka nui a me ka mānoanoa o ke kaumaha, ʻoi aku ka maikaʻi o ka hana ʻana i ka wai. Inā loaʻa nā kulu wai ma ka ʻili o ka lole i ulana ʻole ʻia, e paheʻe pololei nā kulu wai mai ka ʻili.

ʻO ka polyester non-woven fabric ke kū'ē i nā wela kiʻekiʻe. Ma muli o ka hoʻoheheʻe ʻana o ka polyester ma kahi o 260 ° C, hiki iā ia ke mālama i ka paʻa o nā ana o waho o nā lole i ulana ʻole ʻia i nā wahi e pono ai ke kūpaʻa wela. Ua hoʻohana nui ʻia i ka paʻi ʻana i ka wela, ka kānana ʻana o ka ʻaila hoʻouna, a me kekahi mau mea i hoʻohui ʻia e koi ai i ke kūʻokoʻa wela kiʻekiʻe.

PET spunbond lole i ulana ʻole ʻiahe ʻano lole filament ʻaʻole i ulana ʻia ka lua wale nō ma mua o ka lole i ulana ʻole ʻia ka nylon spunbond. ʻO kona ikaika maikaʻi loa, maikaʻi ka ea permeability, tensile resistance, nā waimaka a me nā waiwai anti-aging i hoʻohana ʻia i nā ʻano like ʻole e nā poʻe hou aʻe.

He waiwai kino kūikawā ko ka PET spunbond non-woven: kū'ē i nā kukuna gamma. ʻO ia hoʻi, inā pili i nā huahana lapaʻau, hiki ke hoʻohana pololei ʻia nā kukuna gamma no ka disinfection me ka ʻole o ka hōʻino ʻana i ko lākou mau waiwai kino a me ke kūpaʻa dimensional, ʻo ia ka waiwai kino i loaʻa ʻole i ka polypropylene (PP) spunbond non-woven fabrics.

Polypropylene lole ʻaʻole i ulana ʻia

ʻO ka lole spunbonded non-woven e pili ana i ka filament mau i hana ʻia e ka extrusion a me ka hohola ʻana o nā polymers, i waiho ʻia i loko o kahi pūnaewele. Hoʻopili ʻia ka pūnaewele iā ia iho, thermally bonded, chemically bonded or mechanically reinforced to turn the web into non-woven fabric.Used for disposable hygiene products, like sanitary napkins, surgical gowns, papale, masks, moena, diaper fabrics, etc.

ʻAʻole i ulana ʻia ka polypropylene vs polyester

ʻO ka PP he polypropylene maka, ʻo ia hoʻi ka polypropylene fiber, nona ka lole lahilahi ʻaʻole i ulana ʻia; ʻO PET kahi mea hou polyester maka, ʻo ia hoʻi ka polyester fiber, ʻaʻohe mea hoʻohui i ke kaʻina hana holoʻokoʻa. He huahana maikaʻi maikaʻi loa ia a pili i ka lole mānoanoa ʻaʻole i ulana ʻia.

ʻO ka ʻokoʻa ma waena o ka polypropylene a me ka polyester fibers

1、 Kumu hana

ʻOkoʻa nā loina hana o ka polypropylene a me ka polyester fiber. Hoʻomākaukau ʻia ka polypropylene ma ka hoʻomehana ʻana i ka propylene monomers i ka wela kiʻekiʻe a hoʻohui iā lākou i kahi catalyst no ka polymerization, ʻoiai ʻo nā fibers polyester e hana ʻia i mau mea fiber ma o ka hoʻohui ʻana i nā mea hana etherification cellulose a me nā mea hoʻoheheʻe i ka resin polyester.

2、 Nā hiʻohiʻona waiwai

1. Ma ke ano o na waiwai kino:

He māmā ka polypropylene a he kiʻekiʻe ka ikaika o ka fiber, akā maikaʻi ʻole kona pale ʻana a me ke kūpaʻa wela kiʻekiʻe. He kiʻekiʻe ka ikaika a me ka lōʻihi o ka polyester fibers, a me ka wela a me ke kū'ē kemika, e hopena i ka lōʻihi o ke ola lawelawe.

2. Ma ke ano o na waiwai kemika:

ʻO ka polypropylene he mau waiwai kemika paʻa, ʻaʻole hiki ke ʻino ʻia e nā waikawa, alkalis, etc. Loaʻa i ka fiber polyester kahi ʻano apo benzene a loaʻa kahi pae o ka pale ʻana i ka corrosion.

3. Ma ke ʻano o ka launa kaiapuni:

ʻO ka polypropylene kahi mea thermoplastic ʻaʻole hiki ke hoʻoheheʻe ʻia a hoʻohaumia i ke kaiapuni. Hiki ke hoʻohaʻahaʻa ʻia nā fiber polyester e nā microorganism a ʻaʻole e hoʻohaumia i ke kaiapuni.

ʻO ka ʻokoʻa ma waena o ka lole i ulana ʻole ʻia PP a mePET lole i ulana ʻole ʻia

1. He mea maʻalahi ka PP, a he pipiʻi nā mea waiwai PET. Hiki ke hana hou i ka ʻōpala PP i loko o ka umu, ʻoiai ʻaʻole hiki ke hana hou ʻia ka ʻōpala PET, no laila ua emi iki ke kumu kūʻai o PP.

2. He kiʻekiʻe ka pale wela o PP ma kahi o 200 degere, ʻoiai ʻo PET ka pale wela ma kahi o 290 degere. ʻOi aku ka pale ʻana o PET i nā mahana kiʻekiʻe ma mua o PP.

3. ʻAʻole i ulana ʻia i ka lole paʻi, wela ka hopena, like ka laulā PP emi ʻoi aku ka nui, ʻoi aku ka liʻiliʻi o ka PET, ʻoi aku ka maikaʻi o ka hopena, ʻoi aku ka mālama ʻana o ka PET a me ka liʻiliʻi.

4. ʻO ka ikaika tensile, ka hoʻopaʻapaʻa, ka haʻahaʻa haʻahaʻa, a me ke kaumaha like, ʻoi aku ka ikaika o ka tensile o ka PET, ka hoʻopaʻapaʻa, a me ka lawe ʻana i ka ukana ma mua o PP. ʻO 65 grams o PET ka like me 80 grams o PP ma ke ʻano o ka ʻāʻī, ke ʻano, a me ka hiki ke amo.

5. Mai kahi hiʻohiʻona kaiapuni, ua hui pū ʻia ʻo PP me nā ʻōpala PP i hana hou ʻia, a he mea hou nā pahu PET a pau. ʻOi aku ka maʻemaʻe o ka PET ma mua o PP.
