Kwiminyaka yakutshanje, iifiber ze-cellulose ezihlaziyiweyo (ezifana ne-viscose, i-modal, i-Tencel kunye nezinye iifayibha) ziye zavela ngokuqhubekayo, ezingahlanganisi nje iimfuno zabantu ngexesha elifanelekileyo, kodwa zinciphisa ngokuyinxenye iingxaki zokunqongophala kwezixhobo kunye nokutshatyalaliswa kwendalo.
Ngenxa yokuba ifayibha yeselulosi ehlaziyiweyo ineengenelo zefiber yeselulosi yendalo kunye nefayibha yokwenziwa, isetyenziswa kakhulu kwilaphu elinomlinganiselo ongazange ubonwe ngaphambili.
01.Ifiber ye-viscose eqhelekileyo
I-Viscose fiber ligama elipheleleyo le-viscose fiber. Yifiber ye-cellulose efunyenwe ngokukhupha kunye nokuhlaziya iimolekyuli zefiber kwi-cellulose yomthi wendalo kunye "nomthi" njengento ekrwada.
Indlela yokulungiselela: i-cellulose yesityalo i-alkalized ukwenza i-alkali cellulose, kwaye emva koko isabela nge-carbon disulfide ukwenza i-cellulose xanthate. Isisombululo se-viscous esifunyenwe ngokunyibilika kwisisombululo se-alkaline edibeneyo sibizwa ngokuba yi-viscose. I-Viscose yenziwe ibe yifayibha ye-viscose emva kokujikeleza okumanzi kunye nochungechunge lweenkqubo zokucwangcisa
I-non-uniformity yenkqubo yokubumba eyinkimbinkimbi ye-fiber ye-viscose eqhelekileyo iya kwenza i-cross-section ye-fiber ye-viscose eqhelekileyo ibonakala esinqeni okanye ingaqhelekanga, kunye nemingxuma ngaphakathi kunye ne-grooves engaqhelekanga kwi-longitudinal direction. I-Viscose inokufunxeka kakuhle kokufuma kunye nokudaya, kodwa imodyuli namandla ayo aphantsi, ngakumbi amandla ayo okumanzi aphantsi.
02.Modal fiber
I-Modal fiber ligama lokurhweba le-modulus viscose fiber ephezulu. Umahluko phakathi kwefiber ye-modal kunye ne-viscose ye-fiber eqhelekileyo kukuba i-modal fiber iphucula ukungahambi kakuhle kwamandla aphantsi kunye ne-modulus ephantsi ye-fiber ye-viscose eqhelekileyo kwimeko emanzi, kwaye inamandla aphezulu kunye ne-modulus kwimeko emanzi, ngoko ihlala ibizwa ngokuba yi-modulus emanzi ephezulu ye-viscose. ifayibha.
Iimveliso ezifanayo zabavelisi befayibha abahlukeneyo banamagama ahlukeneyo, anje ngeLenzing modal TM brand fiber, polynosic fiber, Fuqiang fiber, hukapok kunye ne-newal brand name yenkampani yeLanzing eOstriya.
Indlela yokulungiselela: Imodyuli ephezulu emanzi ifunyenwe yinkqubo ekhethekileyo yenkqubo yokuvelisa. Ukwahluka kwinkqubo yokuvelisa ifayibha ye-viscose ngokubanzi:
(1) I-cellulose kufuneka ibe neqondo eliphezulu le-polymerization (malunga ne-450).
(2) Isisombululo sesitokhwe esilungisiweyo sinoxinzelelo oluphezulu.
3 . Izakhiwo zangaphakathi kunye nezangaphandle zeentambo ezifunyenwe ngale ndlela zifana ngokufanayo. Ubume be-skin core layer ye-cross-section ye-fibers ayibonakali njengento eqhelekileyo ye-viscose fibers. Ubume obunqamlezileyo buthande ukuba setyhula okanye isinqe sesetyhula, kwaye umphezulu welongitudinal ulula. Iintsinga zinamandla aphezulu kunye nemodulus kwimeko emanzi, kunye neempawu ezibalaseleyo zehygroscopic nazo zifanelekile kwiimpahla zangaphantsi.
Ubume bomaleko bangaphakathi nangaphandle befiber bufana ngokufanayo. Ubume bomgangatho we-skin core we-fiber cross-section ayibonakali kangako kune-fiber ye-viscose eqhelekileyo. Ubume obunqamlezayo buthanda ukuba bungqukuva okanye esinqeni, kwaye ulwalathiso lwelongitudinal luthambile. Inamandla aphezulu kunye nemodyuli kwimeko emanzi kunye nokusebenza kakuhle kokufunxa ukufuma.
03.Lessel fiber
Ifayibha ye-Lyocell luhlobo lwefiber eyenziweyo ye-cellulose, eyenziwe nge-polymer cellulose yendalo. Yasungulwa yinkampani yaseBritane kautor kwaye kamva yatshintshelwa kwinkampani yaseSwitzerland yaseLanjing. Igama lokurhweba nguTencel, kwaye igama elithi "Tiansi" lamkelwa eTshayina.
Indlela yokulungiselela: I-Lyocell luhlobo olutsha lwefiber ye-cellulose elungiselelwe ngokuyinyibilikisa ngokuthe ngqo i-cellulose pulp kwisisombululo esijikelezayo kunye ne-n-methylmoline oxide (NMMO) isisombululo samanzi njengesinyibilikisi, emva koko kusetyenziswa ukujikeleza okumanzi okanye indlela eyomileyo yokujikeleza emanzi, usebenzisa i-concentration ethile. Isisombululo se-nmmo-h2o njengebhafu yokudibanisa ukwenza i-fiber, kwaye emva koko ukusolula, ukuhlamba, ukufaka i-oyile kunye nokomisa i-fiber ephambili e-spun.
Xa kuthelekiswa nendlela yokuvelisa ifayibha ye-viscose eqhelekileyo, inzuzo enkulu yale ndlela yokusonta kukuba i-NMMO inokunyibilikisa ngokuthe ngqo i-cellulose pulp, inkqubo yokuvelisa i-stock spining ingenziwa lula kakhulu, kwaye izinga lokubuyisela le-NMMO linokufikelela ngaphezu kwe-99%, kwaye inkqubo yemveliso ayingcolisi imo engqongileyo.
Ubume be-morphological ye-Lyocell fiber yahluke ngokupheleleyo kwi-viscose eqhelekileyo. Ulwakhiwo olunqamlezileyo lufana, lungqukuva, kwaye alukho ulusu olungundoqo. Umphezulu welongitudinal ugudile kwaye akukho groove. Ineempawu eziphezulu zoomatshini kunefayibha ye-viscose, ukuzinza komgangatho wokuhlamba okulungileyo (izinga le-shrinkage li-2% kuphela) kunye nokunyuka komswakama ophezulu. Inobuhle obukhazimlayo, umqheba othambileyo, ukutsaleka okuhle kunye nobuhle obuhle.
Umahluko phakathi kwe-viscose, i-modal kunye ne-lessel
(1)Icandelo leFayibha
(2)Iimpawu zeFayibha
•Ifayibha yeViscose
• Ifunxa kakuhle ukufuma kwaye iyahlangabezana neemfuno zefiziyoloji yolusu lomntu. Ilaphu lithambile, ligudileyo, liyaphefumla, alifani nombane ongatshintshiyo, ukuxhathisa kwe-UV, ukukhululeka ukunxiba, kulula ukudaya, umbala oqaqambileyo emva kokudaya, ukukhawuleza kombala okulungileyo, kunye nokujikeleza okulungileyo. Imodyuli emanzi iphantsi, isantya sokushwabana siphezulu kwaye kulula ukuyikhubaza. Isandla siziva siqinile emva kokuqalisa, kwaye ukuqina kunye nokumelana nokunxiba akubi kakuhle.
• I-Modal fiber
• Inomchukumisa othambileyo, oqaqambileyo nococekileyo, umbala oqaqambileyo kunye nombala okhawulezayo. Ilaphu livakala ligudile ngakumbi, umphezulu welaphu uqaqambile kwaye uyakhazimla, kwaye ukutsaleka kungcono kunomqhaphu okhoyo, ipolyester kunye nemicu ye-viscose. Inamandla kunye nokuqina kweentsinga zokwenziwa, kwaye inokukhanya kunye nokuziva kwesilika. Ilaphu linokuxhathisa imibimbi kunye nokumelana ne-ayina, ukufunxwa kakuhle kwamanzi kunye nokungena komoya, kodwa ilaphu lihlwempuzekile.
• I-Lessel fiber
• Ineempawu ezininzi ezigqwesileyo zefiber yendalo kunye nefayibha eyenziweyo, i-luster yendalo, imvakalelo egudileyo, ukomelela okuphezulu, ngokusisiseko akukho kuncipha, ukunyanzeliswa kokunyakama okulungileyo kunye nokungena, ithambile, ikhululekile, igudile kwaye ipholile, idonsa kakuhle, ihlala ixesha elide kwaye ihlala ixesha elide.
(3)Ubungakanani besicelo
• Ifayibha yeViscose
•Imicu emifutshane inokuba yi-spun ecocekileyo okanye idityaniswe nezinye iintambo ze-textile, ezifanelekileyo ukwenza iimpahla zangaphantsi, iimpahla zangaphandle kunye namanqaku ahlukeneyo okuhombisa. Ilaphu le-filament lilula kwaye lincinci, kwaye lingasetyenziselwa i-quilt kunye neempahla zokuhombisa ngaphezu kweengubo.
•I-Modal fiber
•Amalaphu ezinithiweyo kaModale asetyenziswa ikakhulu ukwenza impahla yangaphantsi, kodwa nakwimpahla yezemidlalo, impahla eqhelekileyo, ihempe, amalaphu asele enziwe akumgangatho ophezulu, njl. njl.
•I-Lessel fiber
• Ibandakanya onke amabala endwangu, nokuba ngumqhaphu, uboya, isilika, iimveliso zehemp, okanye ukunitha okanye ukuluka, inokuvelisa iimveliso ezikumgangatho ophezulu nezikumgangatho ophezulu.
