Me ka ulu nui ʻana o nā fiber kemika, ʻoi aku ka nui o nā ʻano o nā fibers.Ma waho aʻe o nā fiber maʻamau, nui nā ʻano hou e like me nā fiber kūikawā, nā fiber composite, a me nā fibers i hoʻololi ʻia i ʻike ʻia i loko o nā fiber kemika.I mea e hoʻomaʻamaʻa i ka hoʻokele hana a me ka nānā ʻana i nā huahana, pono ka ʻike ʻepekema o nā fiber textile.
Hoʻokomo ka ʻike fiber i ka ʻike ʻana i nā hiʻohiʻona morphological a me ka ʻike ʻana i nā waiwai kino a me nā mea kemika.Hoʻohana mau ʻia ka nānā ʻana microscopic e ʻike i nā hiʻohiʻona morphological.
Nui nā ʻano e ʻike ai i nā waiwai kino a me nā mea kemika, e like me ke ʻano o ka puhi ʻana, ke ʻano dissolution, ke ʻano kala reagent, ke ʻano melting point, ke ʻano gravity kikoʻī, ke ʻano birefringence, ke ʻano o ka diffraction X-ray a me ke ʻano infrared absorption spectroscopy, etc.
1.Microscope nānā 'ana
ʻO ka hoʻohana ʻana i kahi microscope e nānā i ka morphology longitudinal a me ka cross-sectional o nā fibers ke ala kumu e ʻike ai i nā ʻano lole lole, a hoʻohana pinepine ʻia e ʻike i nā ʻano fiber.He ʻano kūikawā ko kēlā me kēia fiber maoli i hiki ke ʻike pono ʻia ma lalo o kahi microscope.No ka laʻana, palahalaha nā pulupulu pulupulu ma ka ʻaoʻao lōʻihi, me ka wili maoli, ka ʻaoʻao kea o ka pūhaka, a me ka lua waena.Ua wili ʻia ka huluhulu ma ka longitudinally, he mau unahi ma ka ʻili, a he poepoe a oval paha ma ka ʻāpana keʻa.Aia kekahi hulu hipa ma waena.Loaʻa i ka jute nā puʻupuʻu ākea a me nā kaha kū pololei ma ka ʻaoʻao longitudinal, polygonal ka pauku keʻa, a nui ka lua waena.
2. Keʻano o ke ahi
ʻO kekahi o nā ala maʻamau e ʻike ai i nā fiber maoli.Ma muli o ka ʻokoʻa o ka hui kemika o nā fibers, ʻokoʻa nō hoʻi nā ʻano puhi.Hiki ke hoʻokaʻawale ʻia nā fiber cellulose a me nā protein e like me ka maʻalahi o ka puhi ʻana i nā fibers, inā he thermoplastic lākou, ka ʻala i hana ʻia i ka wā o ke ahi, a me nā ʻano o ka lehu ma hope o ke ahi ʻana.
ʻO nā pulupulu cellulose e like me ka pulupulu, ka hemp, a me ka viscose e wela koke i ka wā e hui pū ai lākou me ka lapalapa, a hoʻomau i ke ahi ma hope o ka haʻalele ʻana i ke ahi, me ke ʻala o ka pepa ʻā, e waiho ana i kahi liʻiliʻi o ka lehu hina hina ma hope o ka puhi ʻana;ʻO nā pulupulu pulupulu e like me ka hulu hipa a me ke kilika e wela mālie ke pili me ka lapalapa, a haʻalele i ka lapalapa Ma hope o ia, hoʻomau ʻia ke ahi mālie, me ka ʻala o ka hulu ʻā, e waiho ana i ka lehu ʻeleʻele ma hope o ke ahi ʻana.
| ʻano fiber | kokoke i ka lapalapa | i ke ahi | waiho i ka lapalapa | ʻala ʻā | ʻAno koena |
| Tencel fiber | ʻAʻohe heheʻe a ʻaʻohe emi | puhi koke | e aa mau | pepa puhi | lehu ʻeleʻele hina |
ʻO ke kala kala | ʻAʻohe heheʻe a ʻaʻohe emi | puhi koke | e aa mau | pepa puhi | lehu ʻeleʻele hina |
| pulu ʻohe | ʻAʻohe heheʻe a ʻaʻohe emi | puhi koke | e aa mau | pepa puhi | lehu ʻeleʻele hina |
| Viscose fiber | ʻAʻohe heheʻe a ʻaʻohe emi | puhi koke | e aa mau | pepa puhi | he lehu keʻokeʻo liʻiliʻi |
| poliester fiber | emi hehee | E hoʻoheheʻe mua a laila e puhi, aia ka hāʻule kulu | hiki ke hooloihi i ke ahi | mea ʻala kūikawā | Poʻo ʻeleʻele ʻeleʻele ʻeleʻele paʻakikī |
3.Dissolution ala
Hoʻokaʻawale ʻia nā fibers e like me ka solubility o nā fiber textile like ʻole i nā mea kemika like ʻole.Hiki i kekahi mea hoʻoheheʻe ke hoʻoheheʻe pinepine i nā ʻano fibers, no laila ke hoʻohana ʻana i ke ʻano hoʻoheheʻe e ʻike ai i nā fibers, pono e hoʻomau i nā hoʻāʻo hoʻoheheʻe ʻokoʻa e hōʻoia i ke ʻano o nā fibers i ʻike ʻia.Ke ala hoʻoheheʻe I ka ʻike ʻana i nā ʻāpana hui ʻana o nā huahana i hui ʻia, hiki ke hoʻohana ʻia kekahi mea hoʻoheheʻe e hoʻopau i nā fibers o kekahi mea, a laila hiki ke hoʻohana ʻia kekahi mea hoʻoheheʻe e hoʻopau i nā fibers o ka mea ʻē aʻe.Hiki ke hoʻohana ʻia kēia ʻano hana no ka nānā ʻana i ka haku mele a me ka ʻike o nā fibers like ʻole i nā huahana i hui ʻia.Ke ʻokoʻa ka ʻike a me ka mahana o ka solvent, ʻokoʻa ka solubility o ka fiber.
Hiki ke hoʻokomo ʻia ka fiber e ʻike ʻia i loko o kahi paipu hoʻāʻo, hoʻokomo ʻia me kahi mea hoʻoheheʻe, hoʻoulu ʻia me ke koʻokoʻo aniani, a ʻike ʻia ka hemo ʻana o ka fiber.Inā he liʻiliʻi loa ka nui o nā fibers, hiki ke hoʻokomo ʻia ka hāpana i loko o kahi paheʻe aniani concave me kahi ʻili concave, kulu ʻia me ka solvent, uhi ʻia me ka pahe aniani, a nānā pono ma lalo o ka microscope.I ka hoʻohana ʻana i ke ʻano hoʻoheheʻe e ʻike ai i nā fibers, pono e hoʻomalu pono ʻia ka neʻe ʻana o ka solvent a me ka mahana wela, a pono e uku ʻia i ka wikiwiki o ka hemo ʻana o nā fibers.Pono ka hoʻohana ʻana i ke ʻano dissolution i ka hoʻomaopopo pololei ʻana i nā waiwai kemika fiber, a paʻakikī nā kaʻina hana.
Nui nā ʻano ʻike no ka fiber textile.I ka hoʻomaʻamaʻa, ʻaʻole hiki ke hoʻohana ʻia kahi ala hoʻokahi, akā pono nā ʻano hana no ka nānā ʻana a me ka noiʻi.ʻO ke kaʻina hana o ka ʻike pono ʻana o nā fiber, ʻo ia ka hoʻohui ʻepekema i kekahi mau ʻano ʻike.
