Nui nā loina humuhumu ma ka mākeke.Ma waena o lākou, ʻelua mau ʻano maʻamau o ke ad humuhumu polyester.A laila e hōʻike mākou iā ʻoe i ka ʻokoʻa ma waena o ka ʻili polyester a me ke kaula nylon.
E pili ana i ka polyester
He ʻano koʻikoʻi ka polyester i ka fiber synthetic a ʻo ia ka inoa kālepa o ka fiber polyester ma Kina.He polimer hana pulupulu i hana ʻia e ka esterification a i ʻole transesterification a me ka polycondensation o PTA a i ʻole DMT a MEG-Polyethylene terephthalate (PET).He fiber ia i hana ʻia e ka milo a me ka mālama ʻana.
E pili ana i ka nylon
Ua hoʻomohala ʻia ʻo Nylon e Carothers, he kanaka ʻepekema ʻAmelika, a he hui noiʻi i alakaʻi ʻia e ia.ʻO ia ka fiber synthetic mua loa ma ka honua.ʻO Nylon kahi ʻano o ka fiber polyamide.Ua hoʻololi ka hiʻohiʻona o ka nylon i nā huahana textiles.ʻO kāna synthesis kahi holomua nui i ka ʻoihana fiber synthetic a he mea koʻikoʻi loa ia i ka kemika polymer kiʻekiʻe.
Nā ʻokoʻa o ka hana
hana naylon
Paʻa, ʻaʻahu-pale, hoʻonohonoho mua ma waena o nā fibers āpau.ʻO kona pale ʻana he 10 mau manawa o ka pulupulu a me ka maloʻo viscose fiber, a me 140 mau manawa o ka pulu pulu.No laila, maikaʻi loa kona lōʻihi.ʻO ka hoʻihoʻi elastic a me ka elastic o kaʻO ka lole nylonmaikaʻi loa, akā hiki ke hoʻololi ʻia e ka ikaika o waho, no laila ua maʻalahi ka lole i ka wā o ke kaʻina hana.He ʻilihune i ka ea uila a maʻalahi hoʻi e hana i ka uila paʻa.
Hana Polyester
Ka ikaika kiʻekiʻe
ʻO ka ikaika o ka fiber pōkole he 2.6 a 5.7 cN/dtex, a ʻo ka fiber ikaika kiʻekiʻe he 5.6 a 8.0 cN/dtex.Ma muli o kona hygroscopicity haʻahaʻa, ʻo kona ikaika pulu ka mea like me ka ikaika maloʻo.ʻO ka ikaika o ka hopena he 4 mau manawa kiʻekiʻe ma mua o ka nylon a he 20 mau manawa kiʻekiʻe ma mua o ka viscose.
Elasticity maikaʻi
Ua kokoke ka elasticity i ka hulu hipa, i ka wā e hohola ʻia e 5% a 6%, hiki ke hoʻihoʻi hou ʻia.ʻOi aku ka maikaʻi o ke kūpaʻa wrinkle ma mua o nā fibers ʻē aʻe, ʻo ia hoʻi, ʻaʻole wrinkled ka lole, a maikaʻi ke kūpaʻa dimensional.ʻO ka modulus o ka elasticity he 22 a 141 cN/dtex, ʻo ia ka 2 a 3 mau manawa kiʻekiʻe ma mua o ka nylon.
Maikaʻi ka wai
Kūleʻa wili maikaʻi.ʻO ka pale ʻana o ka polyester ka lua ma mua o ka nylon.ʻOi aku ka maikaʻi ma mua o nā fila kūlohelohe a me ka synthetic, a ʻo kona pale māmā ka lua wale nō i ka fiber acrylic.
ʻO nā ʻokoʻa ma waena o ka hoʻohana ʻana i ka polyester a me ka nylon
Ke noʻonoʻo nei i ka hygroscopicity, he ʻano maikaʻi ka lole nyion i nā lole synthetic, no laila ʻoi aku ka maikaʻi o nā lole i hana ʻia me ka nylon ma mua o nā lole polyester.He maikaʻi ka sputum a me ke kūpaʻa corosion, akā ʻaʻole lawa ka wela a me ka lghtresistance. Pono e hoʻohālikelike ʻia ka mahana roning ma lalo o 140 ℃C. he fabic māmā, i hoʻopili wale ʻia nā lole polypropylene a me nā lole acrylic i nā lole synthetic.No laila, kūpono ia no ka lole mauna a me ka lole hoʻoilo.
He hygroscopicity maikaʻi ʻole ka lole polyester a sultry ke komo.He mea maʻalahi ke lawe i ka uila static a me ka lepo lepo, e pili ana i ka helehelena a me ka hōʻoluʻolu.Eia naʻe, maʻalahi loa ka maloʻo ma hope o ka holoi ʻana, ʻaʻole deformed.ʻO ka polyester ka lole pale wela maikaʻi loa i nā lole synthetic.ʻO ka helu hoʻoheheʻe he 260 ° C a hiki i ka mahana hao ke 180 ° C. Loaʻa iā ia kahi hana thermoplastic a hiki ke hana ʻia i kahi pālule pleated me nā pleats lōʻihi.
ʻAʻole maikaʻi ka hoʻoheheʻe ʻana o ka lole polyester, a maʻalahi ka hana ʻana i nā lua ma ke ʻano o ka soot a i ʻole mars.No laila, ʻo ka hoʻohana ʻana i ka lole polyester e pale aku i ka hoʻopili ʻana me nā ʻōpala cigareti, nā ʻulaʻula, a me nā mea ʻē aʻe. ʻO nā lole polyester he kūpaʻa wrinkle maikaʻi a me ka paʻa ʻana o ke ʻano, no laila kūpono lākou i nā lole o waho.
