ʻO ka ʻokoʻa ma waena o ka polyester (PET) i ulana ʻole ʻia a me ka lole PP nonwoven

Hoʻolauna kumu oPP lole ʻaʻole i ulana ʻiaa me ka polyester i ulana ʻole ʻia

ʻO ka lole PP nonwoven, iʻikeʻia hoʻi he polypropylene non-woven fabric, i hanaʻia me nā polypropylene fibers i hoʻoheheʻeʻia a wiliʻia i nā mahana kiʻekiʻe, hoʻomaha, kikoo, a ulanaʻia i loko o ka lole i ulanaʻoleʻia. Loaʻa iā ia nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa, ka māmā, ka hanu, a me ka hoʻokuʻu wai. He haʻahaʻa haʻahaʻa ka maikaʻi o ka lole polypropylene non-woven a maʻalahi ke kumukūʻai.

ʻO ka polyester non-woven fabric, ka mea i kapa ʻia ʻo ka polyester non-woven fabric, he lole i ulana ʻole ʻia i hana ʻia e ka hana ʻana i nā fibers polyester ma o nā kaʻina like ʻole e like me ka wela a me nā mea hoʻohui kemika. He kiʻekiʻe stretchability, toughness, friction kū'ē, wela kū'ē, corrosion kū'ē, a smoothness. ʻO ka maikaʻi o ka lole polyester non-woven he mea kiʻekiʻe a he pipiʻi ke kumukūʻai.

ʻO ka ʻokoʻa ma waena o ka lole nonwoven PP a me ka lole polyester non-woven

ʻokoʻa waiwai

Ma keʻano o nā mea maka, e pili anaʻo PP i ka polypropylene, iʻikeʻia hoʻi he polypropylene; ʻO ka PET e pili ana i ka polyester, i kapa ʻia ʻo polyethylene terephthalate. ʻOkoʻa nā helu hoʻoheheʻe o nā huahana ʻelua, ʻoi aku ka helu heheʻe o ka PET ma luna o 250 degere, aʻo ka PP he 150 degere wale nō. He keʻokeʻo keʻokeʻo ka polypropylene, a ʻoi aku ka haʻahaʻa o nā fiber polypropylene ma mua o nā fiber polyester. ʻO ka polypropylene ka waika a me ka alkali pale akā ʻaʻole kūʻokoʻa i ka wā kahiko, ʻoiai ʻo ka polyester ke kūpaʻa ʻelemakule akā ʻaʻole kū i ka waikawa a me ka alkali. Inā makemake kāu hana hope i ka umu a i ʻole ka wela wela ma luna o 150 degere Celsius, hiki ke hoʻohana wale ʻia ka PET.

ʻokoʻa kaʻina hana hana

Hoʻohana ʻia ka polypropylene non-woven fabric ma o ka wela wela o ka hoʻoheheʻe ʻana, ka hoʻoluʻu ʻana, ka hoʻolōʻihi ʻana, a me ka ʻupena i loko o ka lole i ulana ʻole ʻia, ʻoiai ka polyester non-woven fabric e hana ʻia ma o nā kaʻina like ʻole e like me ka wela a me nā mea hoʻohui kemika. Hoʻoholo pinepine nā ʻano hana hana like ʻole i ka noi hope. ʻO ka ʻōlelo pili, ʻoi aku ka kiʻekiʻe a me ke kumukūʻai ʻo PET. ʻO ka PET polyester non-woven fabric he: ʻo ka mea mua, ʻoi aku ka maikaʻi ma mua o ka polypropylene non-woven fabric, i hōʻike nui ʻia i ka ikaika, ke kūpaʻa a me nā waiwai ʻē aʻe. Ma muli o ka hoʻohana ʻana i nā mea waiwai kūikawā a me nā mea hana kiʻekiʻe i lawe ʻia mai, a me nā ʻenehana hana paʻakikī a me ka ʻepekema, ʻoi aku ka nui o ka polyester non-woven fabric ma mua o ka ʻenehana a me nā koi o ka polypropylene non-woven fabric.

ʻokoʻa ʻano

ʻO ka lole polypropylene non-woven i nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa, ka māmā, ka hanu, a me ka hoʻokuʻu ʻana o ka wai, ʻoiaipolyester lole ʻaʻole i ulana ʻiaʻoi aku ka kiʻekiʻe o ka stretchability, toughness, heat resistance, corrosion resistance, and smoothness. He kiʻekiʻe ka pale wela o ka PP ma kahi o 200 degere, ʻoiai ʻo PET ka pale wela kiʻekiʻe ma kahi o 290 degere, a ʻoi aku ka pale ʻana o PET i nā wela kiʻekiʻe ma mua o PP. ʻO ka paʻi ʻole i ulana ʻia, ka hopena hoʻololi wela, ʻo PP me ka laulā like ʻole e emi iho, ʻoi aku ka liʻiliʻi o ka PET a ʻoi aku ka maikaʻi o ka hopena, ʻoi aku ka maikaʻi o ka PET a me ka liʻiliʻi o ka pau ʻole. ʻO ka ikaika tensile, ka hoʻopaʻapaʻa, ka hiki ke amo, a me ke kaumaha hoʻokahi, ʻoi aku ka ikaika o ka tensile PET, ka hoʻopaʻapaʻa, a me ka hiki ke halihali i ka ukana ma mua o PP. ʻO 65 grams o PET ka like me ka ikaika tensile, ka ʻāʻī, a me ka hiki ke amo o 80 grams o PP. Mai kahi hiʻohiʻona kaiapuni, ua hui pū ʻia ʻo PP me ka ʻōpala PP i hana hou ʻia, ʻoiai ʻo PET i hana ʻia me nā ʻāpana polyester hou, e hana ana i ka PET i ʻoi aku ka maikaʻi a me ka maʻemaʻe ma mua o PP.

He 0.91g/cm wale nō ka mānoanoa o ka lole PP non-woven, e lilo ia i mea māmā loa ma waena o nā fiber kemika maʻamau. Ke amorphous loa ka lole polyester non-woven, 1.333g/cm kona mānoanoa. ʻO ka lole PP non-woven he kūʻokoʻa māmā, ʻaʻole kū i ka lā, a hiki ke ʻelemakule a me ka brittleness. ʻO ka lole polyester non-woven: Loaʻa iā ia ke kūpaʻa māmā maikaʻi a nalowale 60% o kona ikaika ma hope o 600 mau hola o ka ʻike ʻana o ka lā.

Nā hiʻohiʻona noiʻi like ʻole

ʻO kēia mau ʻano ʻelua o nā lole i ulana ʻole ʻia he ʻokoʻa koʻikoʻi i ka hoʻohana ʻana, akā hiki ke hoʻololi ʻia i kekahi mau ʻano. He ʻokoʻa wale nō ka hana. ʻOi aku ka kiʻekiʻe o ka pōʻai anti-kahiko o nā lole i ulana ʻole ʻia ma mua o kēlānā lole i ulana ʻole polypropylene. Hoʻohana ka polyester non-woven fabrics i ka polyvinyl acetate e like me ka mea maka, a kū i ka moth, abrasion a me nā kukui ultraviolet. ʻOi aku ka kiʻekiʻe o nā hiʻohiʻona o luna ma mua o nā lole polypropylene non-woven. Ke hoʻohālikelike ʻia me ka polypropylene a me nā lole i ulana ʻole ʻia, ʻo ka polyester non-woven fabric he mau waiwai maikaʻi loa e like me ka mea ʻaʻole e hoʻopili ʻia, ka wai-kūpaʻa, a me ka hanu ikaika.

Ka hopena

I ka hōʻuluʻulu manaʻo, ʻelua mau mea i ulana ʻole ʻia ka polypropylene a me ka polyester non-woven fabric. ʻOiai aia kekahi mau ʻokoʻa i nā mea, nā kaʻina hana, a me nā hiʻohiʻona, he ʻokoʻa pū kekahi i nā hiʻohiʻona noi. Ma ke koho wale ʻana i nā mea lole i ulana ʻole ʻia e pili ana i nā pono kikoʻī hiki iā mākou ke hoʻokō maikaʻi i nā koi hana.

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.
