Mumakore achangopfuura, maregenerated cellulose fibers (akadai seviscose, modal, Tencel uye mamwe mafiber) ave achibuda nguva dzose, izvo zvisingaite chete zvinodiwa nevanhu panguva yakakodzera, asiwo zvishoma kuderedza matambudziko ekushomeka kwezviwanikwa uye kuparadzwa kwezvakatipoteredza.
Nekuti regenerated cellulose fiber ine zvakanakira zvechisikigo cellulose fiber uye synthetic fiber, inoshandiswa zvakanyanya mumucheka ine chiyero chisingaenzaniswi chekushandiswa.
01.Ordinary viscose fiber
Viscose fiber ndiro zita rakazara re viscose fiber.Iyo cellulose fiber inowanikwa nekubvisa uye kugadzirisa mamorekuru efiber kubva kuhuni huni cellulose ine "huni" seyakagadzirwa.
Kugadzirira nzira: chirimwa cellulose inogadziriswa kuti igadzire alkali cellulose, uyezve inopindirana necarbon disulfide kugadzira cellulose xanthate.Iyo viscous solution inowanikwa nekunyungudika mu dilute alkaline solution inonzi viscose.Viscose inoumbwa kuita viscose fiber mushure mekunyorova kutenderera uye akatevedzana ekugadzirisa maitiro
Iyo isiri-uniform yeyakaomesesa kuumbwa maitiro eyakajairwa viscose fiber ichaita kuti muchinjiko-chikamu cheyakajairwa viscose fiber ionekwe chiuno chakatendereka kana chisina kujairika, ine maburi mukati uye asina kujairika grooves munzira refu.Viscose ine yakanakisa kunwisa hunyoro uye dyeability, asi modulus yayo uye simba zvakaderera, kunyanya kunyorova kwayo kwakadzikira.
02.Modal fiber
Modal fiber izita rekutengesa repamusoro wet modulus viscose fiber.Musiyano uripo pakati pe modal fiber uye yakajairwa viscose fiber ndeyekuti modal faibha inonatsiridza kuipa kwesimba rakaderera uye yakaderera modulus yeyakajairwa viscose fiber munzvimbo yekunyorova, uye zvakare ine yakakwirira simba uye modulus mukunyorova, saka inowanzonzi yakakwira wet modulus viscose. fiber.
Zvigadzirwa zvakafanana zvevagadziri vakasiyana siyana vanewo mazita akasiyana, akadai seLenzing modal TM brand fiber, polynosic fiber, Fuqiang fiber, hukapok uye newal brand zita re lanzing kambani muAustria.
Kugadzirira nzira: Iyo yakakwira yekunyorova modulus inowanikwa neyakakosha maitiro ekugadzira maitiro.Yakasiyana kubva kune yakajairwa viscose fiber kugadzira maitiro:
(1) Cellulose inofanirwa kunge iine yakakwira avhareji degree yekupolymerization (inenge 450).
(2) Iyo yakagadzirira kutenderera stock solution ine yakanyanya kudzika.
(3) Iyo yakakodzera kuumbwa kweiyo coagulation bath (yakadai sekuwedzera zvirimo zinc sulfate mairi) inogadzirwa, uye tembiricha yecoagulation yekugezesa inoderedzwa kunonoka kuumba kukurumidza, izvo zvinoita kuti uwane fiber ine compact chimiro uye yakakwirira crystallinity. .Zvimiro zvemukati nekunze zvemukati zvefibers zvinowanikwa nenzira iyi zvakafanana.Iyo yeganda core layer chimiro chemuchinjiko-chikamu chefibers haisi pachena seyakajairika viscose fibers.Muchinjikwa-sectional chimiro chinowanzoita denderedzwa kana chiuno chakatenderera, uye iyo longitudinal pamusoro inenge yakatsetseka.Iwo mafiber ane simba rakawanda uye modulus munzvimbo yekunyorova, uye yakanakisa hygroscopic zvimiro zvakakodzerawo zvipfeko zvemukati.
Chimiro chemukati nekunze kwezvikamu zvefiber zvinenge zvakafanana.Mamiriro eganda repakati peganda refiber cross-section haina kujeka kupfuura iyo yakajairwa viscose fiber.Chimiro chemuchinjiko chinowanzoita chakaita denderedzwa kana chiuno chakatenderedza, uye kutungamira kwelongitudinal kunenge kwakatsetseka.Iyo ine yakakwira simba uye modulus mune yakanyorova mamiriro uye yakanakisa mwando kunyudza kuita.
03.Lessel fiber
Lyocell fiber imhando yeartificial cellulose fiber, iyo inogadzirwa neakasikwa cellulose polymer.Yakagadzirwa nekambani yeBritish kautor uye yakazoendeswa kukambani yeSwitzerland Lanjing.Iro zita rekutengesa ndiTencel, uye homonym yaro "Tiansi" inogamuchirwa kuChina.
Kugadzirira nzira: Lyocell rudzi rutsva rweselulosi faibha yakagadzirwa nekunyungudutsa zvakananga cellulose pulp mune inotenderera mhinduro ine n-methylmoline oxide (NMMO) aqueous solution sechinhu chinonyungudutsa, wozoshandisa nyoro kuruka kana yakaoma wet kuruka nzira, uchishandisa imwe confusion ye nmmo-h2o mhinduro seyokugezera yekugezesa kugadzira fiber, uyezve kutambanudza, kugeza, kuzora mafuta uye kuomesa iyo spun primary fiber.
Kuenzaniswa neyakajairwa viscose fiber kugadzira nzira, mukana mukuru weiyi nzira yekuruka ndeyekuti NMMO inokwanisa kunyungudutsa cellulose pulp zvakananga, maitiro ekugadzira ekutenderera stock anogona kurerutswa zvakanyanya, uye kupora kweNMMO kunogona kusvika kupfuura 99%, uye magadzirirwo acho haatombosvibisi nharaunda.
Iyo morphological chimiro cheLyocell fiber chakasiyana zvachose kubva kune yakajairwa viscose.Iyo yemuchinjikwa-chikamu chimiro chakafanana, chakatenderera, uye hapana ganda core layer.Iyo longitudinal pamusoro yakatsetseka uye haina groove.Iyo ine yepamusoro mechanicha zvimiro kupfuura viscose fiber, yakanaka yekugeza dimensional kugadzikana (shrinkage mwero ingori 2%) uye yakanyanya kunyura hunyoro.Iyo ine inoyevedza inopenya, yakapfava mubato, yakanaka drapability uye yakanaka elegance.
Kusiyana pakati pe viscose, modal uye lessel

• Iine zvinhu zvakawanda zvakanakisa zvefiber yakasikwa uye faibha yekugadzira, kupenya kwechisikigo, kunzwa kwakatsetseka, kusimba kwepamusoro, kusinga shrinkage, kupenya kwakanaka kwemwando uye kupera, kupfava, kugadzikana, kutsetseka uye kutonhorera, kudhirowa kwakanaka, kusimba uye kusimba.
(3)Chikamu chekushandisa
• Viscose fiber
•Mahombe mapfupi anogona kuve akachena akarukwa kana kusanganiswa nemamwe machira eshinda, ayo akakodzera kugadzira zvipfeko zvemukati, zvekunze uye zvakasiyana siyana zvekushongedza.Iyo filament jira rakareruka uye rakatetepa, uye rinogona kushandiswa kune quilt uye machira ekushongedza mukuwedzera kune zvipfeko.
•Modal fiber
•Machira akarukwa aModale anonyanya kushandiswa kugadzira zvipfeko zvemukati, asiwo zvemitambo, zvipfeko zvenguva dzose, shati, machira epamusoro-akagadzirwa akagadzirwa, nezvimwe.
•Lessel fiber
• Inobata minda yese yemucheka, ingave donje, shinda, sirika, zvigadzirwa zvehemp, kana kurukwa kana kurukwa, inogona kugadzira zvigadzirwa zvemhando yepamusoro uye zvemhando yepamusoro.
