ʻO ka Modal a me ka rayon nā mea i hana hou ʻia, akā ʻo ka mea maka o Modal he pulp lāʻau, aʻo ka mea maka o ka rayon he fiber maoli. Mai kahi manaʻo, ʻo kēia mau mea ʻelua he mau ʻōmaʻomaʻo. Ma keʻano o ka manaʻo lima a me keʻano, ua like loa lākou, akā, mamao loa ko lākou kumukūʻai mai kekahi i kekahi.
Modal
ʻO ka Modal fiber kahi lole i kūkulu houʻia i nā makahiki i hala iho nei, i kapaʻiaʻo Modal no ka pōkole. ʻO ia ka fiber hou e hoʻohui i ke ʻano nani o nā fiber maoli me ka pono o nā fiber synthetic. Loaʻa iā ia ka palupalu o ka pulupulu, ka ʻulaʻula o ke kilika, a me ka maʻalahi o ka hemp. Eia kekahi, ʻoi aku ka maikaʻi o kona komo ʻana i ka wai a me ka ea permeability ma mua o ka pulupulu, a he kiʻekiʻe kona kiʻekiʻe. He nani a piha ke kala lole. Hiki ke hoʻohui ʻia a hoʻohui ʻia ka fiber Modal me nā ʻano ʻano like ʻole, e like me ka pulupulu, hemp, siliki, a me nā mea ʻē aʻe, e hoʻomaikaʻi i ka maikaʻi o kēia mau lole, i hiki ai i ka lole ke noho mālie a maʻalahi, e hāʻawi i ka pāʻani i nā ʻano o kā lākou. nā fiber, a loaʻa ka hopena maikaʻi aʻe i ka ʻaʻahu.
Rayona
ʻO Rayon ka inoa maʻamau o ka fiber viscose, i kapa ʻia ʻo rayon no ka pōkole. Wehe ʻia ka fiber Viscose mai ka cellulose makaʻala e like me ka lāʻau a me ka mea kanu ligusticum α－ Cellulose, a i ʻole ka pulupulu i hana ʻia e ke kanaka i hana ʻia mai ka pulupulu linter, i hana ʻia i mea hoʻoheheʻe wili a laila pulu. ʻO ka hōʻuluʻulu ʻana, ʻo ka rayon kahi ʻano o ka fiber i hana hou ʻia.
Nā ʻokoʻa ma waena o Modal a me Rayon:
ʻO Modal kahi fiber regenerated cellulose o ka fiber modulus viscose mākū nui i hoʻomohala ʻia e Lenzing, Austria. ʻO ka mea maka o kēia fiber he lāʻau beech mai ʻEulopa. Hana mua ʻia i pulp lāʻau, a laila hana ʻia i fiber ma o ke kaʻina wili kūikawā. ʻO nā mea maka o kēia huahana nā mea kūlohelohe a pau, ʻaʻohe mea ʻino i ke kino o ke kanaka, hiki ke hoʻoheheʻe maoli ʻia, a ʻaʻohe pōʻino i ke kaiapuni. ʻO ka modal fiber kahi ʻano o ka cellulose fiber, i hana ʻia mai nā kumu lāʻau i hana ʻia ma ʻEulopa a hana ʻia me ka slurry lāʻau ma o ke kaʻina wili kūikawā. He pulupulu maʻemaʻe maʻemaʻe, nona ka ʻāpana like me ka pulupulu.
Loaʻa i nā huahana Modal ka palupalu maikaʻi a me ka hoʻomaʻamaʻa maikaʻi ʻana i ka wai, akā ʻaʻohe ʻoʻoleʻa ko lākou mau lole. I kēia manawa, hoʻohana nui ʻia i ka hana ʻana i nā lole komo. Hoʻohana nui ʻia nā lole i ulana ʻia e hana i nā lole lalo. Akā ʻo Modal he kala keʻokeʻo keʻokeʻo, maikaʻi ka dyeability a me ka waihoʻoluʻu ʻulaʻula ma hope o ke kala ʻana, ua lawa ia e hoʻohana ʻia e like me ke kapa. Ma muli o kēia, ua lilo ʻo Modal i mea waiwai no nā ʻaʻahu a me nā lole hoʻonaninani. I mea e hoʻomaikaʻi ai i ka paʻakikī maikaʻi ʻole o nā huahana Modal maʻemaʻe, hiki ke hoʻohui ʻia ʻo Modal me nā fibers ʻē aʻe e loaʻa ai nā hopena maikaʻi. Hiki iā JM/C (50/50) ke hoʻoponopono i kēia hemahema. ʻO ka lole i hui ʻia i ulana ʻia me kēia wili e ʻoi aku ka maʻalahi o ka pulupulu a hoʻomaikaʻi i ke ʻano o ka lole. Hiki iā Modal ke hōʻike i kona hiki ke ulana ʻia i ka ulana ʻana i nā lole i ulana ʻia, a hiki ke hoʻohui pū ʻia me nā wili fiber ʻē aʻe e ulana i nā lole like ʻole. Loaʻa i nā huahana Modal nā manaʻolana ākea no ka hoʻomohala ʻana i nā lole hou.
ʻO Rayon ka fiber viscose, kahi ʻano nui o nā fiber i hana ʻia e ke kanaka. Hoʻokumu ʻia ka cellulose alkali mai ka cellulose maoli ma o ka alkalization, a laila hana me ka carbon disulfide e hana i ka cellulose xanthate. ʻO ka hopena viscous i loaʻa ma ka hoʻoheheʻe ʻana iā ia i loko o ka solution alkali dilute i kapa ʻia he viscose. Hoʻokumu ʻia ka fiber Viscose ma hope o ka wili pulu a me kahi ʻano o nā kaʻina hana. ʻO kāna ʻano kumu ʻo ia ka ʻāpana keʻa o cellulose (C6H10O5) ʻaʻohe fiber viscose maʻamau he zigzag ʻili kumu kumu, pololei i ka longitudinal kuhikuhi a grooved i ka transverse kuhikuhi. He ʻāpana kea poepoe ko ka fiber rich coreless structure.
He maikaʻi ka hoʻomaʻamaʻa ʻana o ka ʻili Viscose, a ʻo ka loaʻa hou ʻana o ka wai ma kahi o 13% ma lalo o nā kūlana o ka lewa. Ma hope o ke komo ʻana o ka wai, hoʻonui nui ʻia, a piʻi ke anawaena e 50%, no laila ʻoi aku ka paʻakikī o ka lole a me ka nui o ka emi ʻana ma hope o ka hoʻokomo ʻana i ka wai.
ʻO ka haʻihaʻi ikaika o ka fiber viscose maʻamau ka haʻahaʻa ma mua o ka pulupulu, ma kahi o 1.6 ~ 2.7 cN / dtex; ʻO ka elongation ma ka haʻihaʻi he 16% ~ 22% kiʻekiʻe ma mua o ka pulupulu; Ke emi nui nei ka ikaika pulu, ma kahi o 50% o ka ikaika maloʻo, a piʻi ka elongation pulu ma kahi o 50%. ʻOi aku ka haʻahaʻa o kona modulus ma mua o ka pulupulu, a he maʻalahi ke deform ma lalo o kahi haʻahaʻa liʻiliʻi, ʻoiai ʻoi aku ka maikaʻi o kāna hana hoʻihoʻi elastic, no laila ua maʻalahi ka lole e hoʻolōʻihi a loaʻa ʻole ke kūpaʻa. ʻOi aku ka ikaika o ka fiber waiwai, ʻoi aku ka ikaika ma mua o ka viscose maʻamau, ʻoi aku ka liʻiliʻi o ka elongation i ka wā haki, a maikaʻi ke kūpaʻa dimensional. ʻAʻole maikaʻi ke kūpaʻa abrasion o ka viscose maʻamau, aʻo ka maikaʻi o ka fiber waiwai.
ʻO ka hui kemika o ka viscose fiber ua like ia me ka pulupulu, no laila ʻoi aku ka pale ʻana i ka alkali ma mua o ka pale ʻana i ka waikawa, akā ʻoi aku ka maikaʻi o kona kūpaʻa alkali a me ka waikawa ma mua o ka pulupulu. Loaʻa i ka fiber waiwai maikaʻi ke kūpaʻa alkali a me ke kūpaʻa waikawa. Pēlā nō, ʻano like ka waiwai hoʻoluʻu o ka fiber viscose me ka pulupulu, me ka chromatography dyeing piha a me ka waiwai kala maikaʻi. Eia kekahi, ua like nā mea wela o ka viscose fiber me ka pulupulu, me ka nui o 1.50 ~ 1.52g / cm3 kokoke i ka pulupulu.
ʻO ka fiber viscose maʻamau he hygroscopicity maikaʻi, maʻalahi ke kala, ʻaʻole maʻalahi e hana i ka uila static, a he spinnability maikaʻi. Hiki ke wili ma'ema'e a i hui pū ʻia me nā pulu lole ʻē aʻe. He palupalu ka lole, maʻemaʻe, hanu, ʻoluʻolu e ʻaʻahu, ʻālohilohi ka waihoʻoluʻu a me ka wikiwiki o ka waihoʻoluʻu ma hope o ke kala ʻana. He kūpono ia no ka hana ʻana i nā lole lalo, nā lole waho a me nā ʻatikala hoʻonaninani like ʻole. He māmā a lahilahi nā lole filament, a hiki ke hoʻohana ʻia no ka hana ʻana i nā uhi quilt a me nā lole hoʻonaninani ma waho o nā lole. ʻO nā hemahema o kēia ʻano fiber viscose ʻo ia ka wikiwiki wikiwiki, haʻahaʻa haʻahaʻa haʻahaʻa modulus, kiʻekiʻe shrinkage, maʻalahi deformation, maikaʻi ʻole elasticity a me ke kūpaʻa.
Hōʻuluʻulu manaʻo:
ʻOiai ʻo ka rayon a me ka Modal he mau fiber recycled, hiki ke hoʻololi i ka hopena electrostatic. ʻO ka uila static koʻikoʻi me ka friction e hoʻopuka i ke ahi ākea. I ka hāʻule a me ka hoʻoilo, ʻo ka hana ʻana o ka lole electrostatic reaction ke kumu i ka huluhulu a me ka pilling. I kēia manawa, ʻoi aku ka nui o nā mea kālepa e hoʻohui i ka hoʻopau antistatic i ka pae hope o ka fiber. ʻAʻole hiki i kēia ke hoʻomaikaʻi wale i ka ʻoluʻolu o ka lole, akā pale pū i ka lole mai ka fuzzing a me ka pilling, a hoʻomaikaʻi i ka manaʻo a me ka nani o ka lole. No ka laʻana, hiki i ka ZJ-Z09H non-ionic antistatic agent ke hoʻomaikaʻi maikaʻi i ka absorption moisture a me ka conductivity o ka lole, a me nā waiwai anti fouling a me ka lepo-hōʻoia, a hiki ke hoʻomaikaʻi i ka pilling anti o ka lole ma mua o 0.5 pae. .
