Ulwazi Lwendwangu:Umehluko phakathi kweRayon neModal

I-Modal ne-rayon zombili ziyimicu egaywe kabusha, kodwa impahla eluhlaza ye-Modal iyi-pulp yokhuni, kanti impahla eluhlaza ye-rayon iyi-fiber yemvelo. Ngokombono othile, le micu emibili iyimicu eluhlaza. Ngokuphathelene nokuzizwa kwesandla nesitayela, zifana kakhulu, kodwa amanani azo akude komunye nomunye.

I-Modal

I-Modal fiber iyindwangu esanda kwakhiwa eminyakeni yamuva nje, ebizwa ngokuthi i-Modal ngamafuphi. Kuwumucu wesimanje ohlanganisa ukuthungwa okunethezeka kwemicu yemvelo kanye nokusebenza kwemicu yokwenziwa. Inokuthamba kukakotini, ukucwebezela kukasilika, nokushelela kwe-hemp. Ngaphezu kwalokho, ukumuncwa kwawo kwamanzi kanye nokungena kwawo emoyeni kungcono kunokotini, futhi inodayi ophakeme. Umbala wendwangu ugqamile futhi ugcwele. I-Modal fiber ingahlanganiswa futhi ihlanganiswe nemicu ehlukahlukene, efana ukotini, i-hemp, usilika, njll., ukuze kuthuthukiswe ikhwalithi yalezi zindwangu, ukuze indwangu ihlale ithambile futhi ibushelelezi, inikeze ukudlala kuzici zabo. imicu, futhi uthole umphumela wokugqoka ongcono.

I-Rayon

I-Rayon igama elivamile le-viscose fiber, ebizwa ngokuthi i-rayon ngamafuphi. I-Viscose fibre ikhishwa ku-cellulose izinto zokusetshenziswa zokusetshenziswa ezifana nokhuni nesitshalo i-ligusticum α－ I-Cellulose, noma i-fiber eyenziwe umuntu eyenziwe nge-linter kakotini, ecutshungulwa ibe yisixazululo sesitoko esiphothayo bese siphothwa esimanzi. Ukufingqa, i-rayon iwuhlobo lwefiber evuselelwe kabusha.

Umehluko phakathi kwe-Modal ne-Rayon:

I-Modal iyifayibha evuselelwe kabusha ye-cellulose ye-high wet modulus viscose fiber eyakhiwe yi-Lenzing, e-Austria. Impahla eluhlaza yale fiber izinkuni ze-beech ezivela eYurophu. Iqala yenziwa i-pulp yokhuni, bese icutshungulwa ibe yifayibha ngokusebenzisa inqubo ekhethekile yokuphotha. Izinto zokusetshenziswa zalo mkhiqizo ziyizinto zonke zemvelo, ezingenabungozi emzimbeni womuntu, zingabola ngokwemvelo, futhi azinangozi emvelweni. I-Modal fiber iwuhlobo lwe-cellulose fiber, eyenziwe nge-shrubbery ekhiqizwa eYurophu futhi yenziwe ngodaka ngokhuni ngenqubo ekhethekile yokuphotha. Kuyi-fiber yemvelo ehlanzekile, eyingxenye ye-cotton.

Imikhiqizo ye-Modal inokuthamba okuhle nokumunca umswakama omuhle kakhulu, kepha izindwangu zabo zinokuqina okubi. Manje isetshenziswa kakhulu ekukhiqizeni izingubo zangaphansi. Izindwangu ze-modal knitted zisetshenziselwa ikakhulukazi ukwenza izingubo zangaphansi. Kodwa i-Modal inokucwebezela okumhlophe okusiliva, ukudaya okuhle kakhulu nombala ogqamile ngemva kokudaya, okwanele ukuwenza isetshenziswe njengejazi. Ngenxa yalokhu, i-Modal iye yanda ibe yimpahla yamajazi nendwangu yokuhlobisa. Ukuze kuthuthukiswe ukuqina okungekuhle kwemikhiqizo ye-Modal emsulwa, i-Modal ingaxutshwa neminye imicu ukuze kuzuzwe imiphumela emihle. I-JM/C (50/50) ingalungisa lokhu kushiyeka. Indwangu ehlanganisiwe elukwe ngale ntambo yenza i-cotton fiber iguquguquke futhi ithuthukise ukubukeka kwendwangu. I-Modal ingaphinda ikhombise ukuluka kwayo enqubweni yokuluka yezindwangu ezilukiwe, futhi ingahlanganiswa neminye imicu yefiber ukwaluka izindwangu ezihlukahlukene. Imikhiqizo ye-modal inamathemba abanzi okuthuthukiswa kwezingubo zesimanje.

I-Rayon iyi-viscose fiber, izinhlobonhlobo ezinkulu zemicu eyenziwe umuntu. I-alkali cellulose yakhiwa nge-cellulose yemvelo ngokusebenzisa i-alkalization, bese isabela ne-carbon disulfide ukwenza i-cellulose xanthate. Isixazululo se-viscous esitholwe ngokusihlakaza kusixazululo se-alkali esincibilikayo sibizwa nge-viscose. I-Viscose fiber yakheka ngemva kokuphotha okumanzi kanye nochungechunge lwezinqubo zokwelapha. Ukwakheka kwayo okuyisisekelo ukuthi ingxenye yesiphambano se-cellulose (C6H10O5) ayikho i-viscose fibre ejwayelekile iyisakhiwo esimazombezombe sesikhumba, siqonde kuhlangothi lwe-longitudinal futhi igobe ibheke ngakwelinye icala. Isakhiwo se-fiber ecebile sine-cross-section eyindilinga.

I-Viscose fiber inokumunca kahle umswakama, futhi ukubuyiswa komswakama cishe ku-13% ngaphansi kwezimo ezijwayelekile zomkhathi. Ngemuva kokumunca umswakama, uyanda kakhulu, futhi ububanzi bukhuphuka ngo-50%, ngakho-ke indwangu izwa kanzima futhi inenani elikhulu lokushwabana ngemva kokufakwa emanzini.

Amandla okuphuka kwefayibha ye-viscose evamile iphansi kunaleyo kakotini, cishe 1.6 ~ 2.7 cN/dtex; Ukwelulwa ngesikhathi sekhefu kuphakeme ngo-16% ~ 22% kunokotini; Amandla amanzi ehla kakhulu, cishe amaphesenti angama-50 wamandla omile, futhi ubude obumanzi bukhuphuka cishe ngo-50%. I-modulus yayo iphansi kunaleyo kakotini, futhi kulula ukuyikhubaza ngaphansi komthwalo omncane, kuyilapho ukusebenza kwayo okunwebekayo kokululama kuphansi, ngakho-ke indwangu kulula ukuyinweba futhi ayinakho ukuzinza kwe-dimensional. Amandla e-fiber ecebile, ikakhulukazi amandla amanzi, aphakeme kunalawo e-viscose evamile, ubude ngesikhathi sekhefu mancane, futhi ukuzinza kwe-dimensional kuhle. Ukumelana nemihuzuko ye-viscose evamile kubi, kuyilapho lokho kwefayibha ecebile kuyathuthukiswa.

Ukwakheka kwamakhemikhali efiber ye-viscose kufana nekakotini, ngakho-ke ayizwani ne-alkali kune-asidi, kodwa ukumelana kwayo ne-alkali ne-asidi kubi kakhulu kunokotini. I-fiber ecebile inokumelana okuhle kwe-alkali kanye nokumelana ne-asidi. Ngokufanayo, impahla yokudaya ye-viscose fiber ifana nekakotini, ene-chromatography yokudaya ephelele kanye nempahla enhle yokudaya. Ukwengeza, izici ezishisayo ze-viscose fiber zifana nezokotini, ezinobuningi obungu-1.50 ~ 1.52g/cm3 eduze nalolo lukakotini.

Ifayibha ye-viscose evamile ine-hygroscopicity enhle, kulula ukuyidaya, akulula ukukhiqiza ugesi omile, futhi inokuphenduka okuhle. Imicu emifushane ingaphothwa noma ihlanganiswe neminye imicu yendwangu. Indwangu ithambile, ibushelelezi, iyaphefumula, ikhululekile ukugqoka, umbala ogqamile kanye nokushesha kombala omuhle ngemva kokudaya. Kufanelekile ukwenza izingubo zangaphansi, izingubo zangaphandle kanye nezihloko ezihlukahlukene zokuhlobisa. Izindwangu ze-filament zilula futhi zincane, futhi zingasetshenziselwa ukwenza izembozo ze-quilt nezindwangu zokuhlobisa ngaphezu kwezingubo. Ukungalungi kwalolu hlobo lwe-viscose fiber ukushesha okubi, i-modulus emanzi ephansi, ukuncipha okuphezulu, ukuguqulwa okulula, ukunwebeka okubuthakathaka kanye nokumelana nokugqoka.

Isifinyezo:

Njengoba kokubili i-rayon ne-Modal kuyimicu egaywe kabusha, ukuthengiselana kwe-electrostatic reaction kwenzeka. Ugesi ongaguquki omkhulu kanye nokungqubuzana kuzoveza umlilo ovulekile. Ekwindla nasebusika, imisebenzi yendwangu ye-electrostatic reaction iphinda ibangele ukufiphala kwendwangu kanye nokuphiliswa. Manje abathengisi abaningi ngokwengeziwe bangeza ukuqedela okulwa nokuvuvukala esigabeni sakamuva sefayibha. Lokhu akukwazi nje ukuthuthukisa ukunethezeka kokugqoka kwendwangu, kodwa futhi kuvimbele indwangu kusuka ekuxubeni nasekuphiliseni, futhi kuthuthukise umuzwa nobuhle bendwangu. Isibonelo, i-ZJ-Z09H i-non-ionic antistatic ejenti ingathuthukisa ngempumelelo ukumuncwa komswakama kanye nokuhamba kahle kwendwangu, kanye nezindawo ezilwa nokungcolisa kanye nezindawo ezivikela uthuli, futhi ingathuthukisa ukuphikiswa kwendwangu yendwangu ngezinga elingaphezu kuka-0.5. .
