He aha ka PU Synthetic Leather

ʻO ka ʻili synthetic PU ka ʻili i hana ʻia mai ka ʻili o ka polyurethane.I kēia manawa ua hoʻohana nui ʻia no ka hoʻonani ʻana i nā ukana, nā lole, nā kāmaʻa, nā kaʻa a me nā lako.Ua ʻike nui ʻia e ka mākeke.ʻAʻole māʻona kona ʻano hoʻohana ākea, ka nui a me nā ʻano like ʻole e ka ʻili kūlohelohe kuʻuna.He maikaʻi a maikaʻi ʻole paha ka maikaʻi o ka ʻili PU.ʻOi aku ka maikaʻi o ka ʻili PU maikaʻi ma mua o ka ʻili, me ka hopena maikaʻi a me ka ʻālohilohi.

01: Nā waiwai waiwai a me nā hiʻohiʻona

Hoʻohana ʻia ka ʻili synthetic PU e hoʻololi i ka ʻili kūlohelohe PVC, a ʻoi aku ka kiʻekiʻe o kona kumukūʻai ma mua o ka ʻili kūlohelohe PVC.Ma keʻano o ka hoʻolālā kemika, ua kokoke ia i ka lole ʻili.ʻAʻole pono ka plasticizer e hoʻokō i nā waiwai palupalu, no laila ʻaʻole ia e lilo i paʻakikī a palupalu.I ka manawa like, loaʻa iā ia nā mea maikaʻi o nā kala momona a me nā ʻano like ʻole, a ʻoi aku ka maʻamau o ke kumukūʻai ma mua o ka lole ʻili, no laila e hoʻokipa ʻia e nā mea kūʻai.

ʻO ka mea ʻē aʻe he ʻili PU.ʻO ka maʻamau, ʻo ka ʻaoʻao hope o ka ʻili PU ka papa lua o ka ʻili maka, i uhi ʻia me kahi papa o ka resin PU, no laila ua kapa ʻia ʻo ia he ʻili pipi kiʻiʻoniʻoni.He ʻuʻuku ke kumu kūʻai a he kiʻekiʻe kona hoʻohana.Me ka hoʻololi ʻana o ka ʻenehana, hana ʻia i nā ʻano o nā māka like ʻole, e like me ka ʻili maka ʻelua i lawe ʻia mai.Ma muli o kāna ʻenehana kūʻokoʻa, ka maikaʻi kūpaʻa, nā ʻano moʻolelo a me nā ʻano ʻē aʻe, ʻo ia ka ʻili kiʻekiʻe o kēia manawa, a ʻo kona kumukūʻai a me ka helu ʻaʻole i emi iho ma mua o ka ʻili papa mua.Loaʻa i ka ʻili PU a me ka ʻili maoli ko lākou ʻano ponoʻī.He nani a maʻalahi ka nānā ʻana o ka ʻili PU.He haʻahaʻa ke kumukūʻai, akā ʻaʻole hiki ke ʻaʻahu a maʻalahi ke wāwahi;He pipiʻi ka ʻili maoli, pilikia ka mālama ʻana, akā paʻa.

(1) Ka ikaika kiʻekiʻe, ka lahilahi a me ka elastic, ka palupalu a me ka maʻalahi, ka hanu maikaʻi a me ka wai permeability, a me ka wai.

(2) I ka haʻahaʻa haʻahaʻa, ua mau nō ka ikaika tensile maikaʻi a me ka ikaika flexural, ke kūpaʻa ʻelemakule maikaʻi a me ke kūpaʻa hydrolysis.

(3) ʻAʻole hiki ke ʻaʻahu, a ʻo kona hiʻohiʻona a me kāna hana kokoke i nā mea o ka ʻili maoli.He maʻalahi ke holoi, hoʻokaʻawale a humuhumu.

(4) He laumā a paʻa ka ʻili, hiki ke hoʻohana ʻia no nā ʻano o ka mālama ʻana i ka ʻili a me ke kala.He ʻokoʻa ka ʻokoʻa a he haʻahaʻa ke kumukūʻai.

(5) ʻAʻole maʻalahi ka hoʻopili ʻana i ka wai i ka hoʻonui a me ka deform, a he mea pili i ke kaiapuni.

02: Kaʻina hana a me ka hoʻokaʻawale ʻana

ʻO ka ʻili Nubuck: Ma hope o ka palaki ʻia, ʻulaʻula melemele a waihoʻoluʻu, ua hana ʻia kona ʻili i kahi papa luna e like me ka lauoho maikaʻi o ka ʻili suede.ʻOiai ʻo ia ke ʻano o ka ʻili luna, ʻoiai ua nāwaliwali ka ikaika o ka ʻili e ke kaʻina hana kiʻi i kekahi ʻano, ʻoi aku ka ikaika ma mua o ka ʻili suede maʻamau.

ʻIli lio pupule: He lima ʻoluʻolu kona manaʻo, ʻoi aku ka maʻalahi a me ka ikaika, loaʻa nā wāwae elastic, a e loli ka ʻili i ka wā e paʻi ʻia e ka lima.Pono e hana ʻia me ka ʻili holoholona o ke poʻo.Ma muli o ka maʻalahi a me ka ikaika o ka ʻili lio, hoʻohana ka hapa nui o lākou i ka ʻili lio papa poʻo.Eia naʻe, no ka nui o ka manawa o kēia kaʻina hana ʻili, he liʻiliʻi nā mea maka, a he kumukūʻai kiʻekiʻe, ʻo ka ʻili lio pupule ka mea maʻamau ma waena a me ka mākeke ʻili kiʻekiʻe.

ʻili aniani PU: ʻoluʻolu ka ʻili.Hoʻohana nui ʻia ka ʻili e hoʻomālamalama i ka ʻili a hōʻike i ka hopena aniani.No laila, kapa ʻia ka ʻili aniani.ʻAʻole paʻa loa kona mau mea.

ʻO ka ʻili synthetic ultrafine fiber: he ʻano hou o ka ʻili kiʻekiʻe kiʻekiʻe i hana ʻia me nā fiber maikaʻi loa.Ua kapa ʻia e kekahi poʻe ʻo ka hā o ka hanauna o ka ʻili kūlohelohe, kahi i hoʻohālikelike ʻia me ka ʻili kūlohelohe kiʻekiʻe.Loaʻa iā ia ka inherent moisture absorption a me ka ea permeability o ka ʻili maoli, a ʻoi aku ka maikaʻi ma mua o ka ʻili maoli i ke kūʻokoʻa kemika, ke kūpaʻa wai, ka pale ʻana i ka maʻi, etc.

ʻO ka ʻili i holoi ʻia: ʻO ka ʻili PU retro, i kaulana i ʻelua mau makahiki i hala aku nei, e hoʻopili i kahi papa o ka pena wai ma luna o ka ʻili PU, a laila hoʻohui i ka waikawa e holoi ai i ka wai e hoʻopau i ke ʻano o ka pena ma luna o ka ʻili. ka ʻili i holoi ʻia, i mae nā wahi i hoʻokiʻekiʻe ʻia ma luna o ka ʻili e hōʻike i ke kala hope, ʻoiai ʻo nā wahi concave e paʻa i ke kala kumu.He mea hana ka ʻili holoi.Ua like loa kona helehelena a me kona manao me ka ili.ʻOiai ʻaʻole hiki ke hanu e like me ka ʻili, ʻoi aku ka māmā a hiki ke holoi ʻia.ʻOi aku ke kumukūʻai ma mua o ka ʻili.

ʻO ka ʻili i hoʻomaʻemaʻe ʻia i ka wai: He huahana plastik i hana ʻia e kekahi kaʻina hana, ʻo ia ka hui ʻana o ka polyvinyl chloride resin, plasticizer a me nā mea hoʻohui ʻē aʻe, i uhi ʻia a i hoʻopili ʻia ma ka ʻili o ka lole.Eia kekahi, aia kekahi mau ʻaoʻao ʻelua PVC ʻili artificial me nā papa plastik ma nā ʻaoʻao ʻelua o ka substrate.

Ka ʻili ʻulaʻula: Hana ʻia ia ma ka hoʻohui ʻana i ka resin discolored i loko o ka ʻili o ka PU a me ka papa BASE o ka ʻili, hoʻoluʻu ʻia, a laila hoʻomaʻamaʻa no ka hoʻokuʻu ʻana i ka pepa i uhi ʻia a i ʻole embossing, a paʻi.Ma hope o ke kaomi wela o ka mea paʻi wela, ua hoʻopili ʻia ka ʻili o ka ʻili i hoʻoheheʻe ʻia i ka hopena carbonization like, e hoʻohālike ana i ka hōʻailona i waiho ʻia e ka ʻili wela ke ʻike ʻia i ka wela kiʻekiʻe, e hopena ana i kahi kala ʻeleʻele o ke kala. ʻo ka ʻili wela, no laila ua kapa ʻia ʻo ia ka ʻili ʻili wela.
