Nyob rau hauv xyoo tas los no, regenerated cellulose fibers (xws li viscose, modal, Tencel thiab lwm yam fibers) tau tshwm sim tsis tu ncua, uas tsis yog tsuas yog ua tau raws li tib neeg cov kev xav tau raws sij hawm, tab sis kuj ib nrab txo cov teeb meem ntawm kev tsis txaus thiab ib puag ncig kev puas tsuaj.
Vim hais tias regenerated cellulose fiber muaj qhov zoo ntawm ntuj cellulose fiber thiab hluavtaws fiber, nws yog dav siv nyob rau hauv textile nrog ib tug unprecedented scale ntawm kev siv.
01.Ordinary viscose fiber ntau
Viscose fiber yog lub npe tag nrho ntawm viscose fiber.Nws yog cov cellulose fiber ntau tau los ntawm kev rho tawm thiab kho cov fiber ntau molecules los ntawm ntuj ntoo cellulose nrog "ntoo" ua raw khoom.
Txoj kev npaj: cog cellulose yog alkalized los tsim alkali cellulose, thiab ces reacts nrog carbon disulfide los tsim cellulose xanthate.Cov kua nplaum uas tau los ntawm kev sib cais hauv dilute alkaline kua yog hu ua viscose.Viscose yog tsim rau hauv viscose fiber tom qab ntub spinning thiab ib tug series ntawm cov txheej txheem
Qhov tsis sib xws ntawm cov txheej txheem molding ntawm cov viscose fiber ntau zoo tib yam yuav ua rau ntu ntu ntawm cov pa viscose fiber ntau tshwm hauv duav puag ncig lossis tsis sib xws, nrog cov qhov hauv thiab qhov tsis sib xws nyob rau hauv txoj kab ntev.Viscose muaj qhov nqus dej zoo heev thiab dyeability, tab sis nws cov qauv thiab lub zog tsis tshua muaj, tshwj xeeb tshaj yog nws lub zog ntub dej tsawg.
02.Modal fiber ntau
Modal fiber yog lub npe lag luam ntawm siab ntub dej modulus viscose fiber.Qhov sib txawv ntawm modal fiber thiab zoo tib yam viscose fiber ntau yog tias modal fiber txhim kho qhov tsis zoo ntawm lub zog tsis tshua muaj zog thiab tsis tshua muaj modulus ntawm cov viscose fiber ntau hauv lub xeev ntub, thiab kuj muaj lub zog siab thiab modulus hauv lub xeev ntub, yog li nws feem ntau hu ua siab ntub modulus viscose. fiber ntau.
Cov khoom zoo sib xws ntawm cov tuam txhab fiber ntau kuj muaj cov npe sib txawv, xws li Lenzing modal TM hom fiber ntau, polynosic fiber, Fuqiang fiber, hukapok thiab lub npe tshiab ntawm lub tuam txhab lanzing hauv Austria.
Txoj kev npaj: Lub siab ntub dej modulus tau txais los ntawm cov txheej txheem tshwj xeeb ntawm cov txheej txheem ntau lawm.Sib txawv ntawm cov txheej txheem viscose fiber ntau:
(1) Cellulose yuav tsum muaj qib siab nruab nrab ntawm polymerization (kwv yees li 450).
(2) Cov tshuaj npaj spinning npaj muaj siab concentration.
(3) Qhov tsim nyog muaj pes tsawg leeg ntawm coagulation da dej (xws li nce cov ntsiab lus ntawm zinc sulfate nyob rau hauv nws) yog npaj, thiab kub ntawm coagulation da dej yog txo kom ncua lub sib sau ceev, uas yog conducive rau tau txais fibers nrog compact qauv thiab siab crystallinity. .Cov txheej txheem sab hauv thiab txheej txheej ntawm cov fibers tau txais hauv txoj kev no yog qhov sib xws.Cov txheej txheem ntawm daim tawv nqaij ntawm tus ntoo khaub lig-section ntawm cov fibers tsis pom tseeb li cov viscose fibers zoo tib yam.Tus ntoo khaub lig-sectional zoo li lub voj voog lossis lub duav ncig, thiab qhov ntev ntawm qhov chaw yog tus du.Cov fibers muaj lub zog siab thiab modulus nyob rau hauv lub xeev ntub, thiab cov khoom zoo hygroscopic kuj haum rau ris tsho hauv qab.
Cov qauv ntawm cov khaubncaws sab nraud povtseg thiab sab hauv ntawm cov fiber ntau yog sib xws.Cov qauv ntawm daim tawv nqaij core txheej ntawm fiber ntau cross-section yog pom tseeb tsawg dua li ntawm cov viscose fiber ntau.Tus ntoo khaub lig-sectional zoo li puag ncig los yog lub duav puag ncig, thiab lub longitudinal kev taw qhia yog tus du.Nws muaj zog thiab modulus nyob rau hauv lub xeev ntub thiab zoo heev noo noo nqus kev ua tau zoo.
03.Lessel fiber ntau
Lyocell fiber yog ib hom khoom siv cellulose fiber ntau, uas yog tsim los ntawm ntuj cellulose polymer.Nws tau tsim los ntawm British kautor tuam txhab thiab tom qab ntawd hloov mus rau Swiss Lanjing tuam txhab.Lub npe lag luam yog Tencel, thiab nws hom lus "Tiansi" tau txais hauv Suav teb.
Txoj kev npaj: Lyocell yog ib hom tshiab ntawm cellulose fiber uas tau npaj los ntawm kev faib cov cellulose ncaj qha mus rau hauv cov tshuaj spinning nrog n-methylmoline oxide (NMMO) aqueous tov raws li cov kuab tshuaj, ces siv ntub spinning los yog qhuav ntub spinning txoj kev, siv ib tug tej yam concentration ntawm nmmo-h2o daws raws li coagulation da dej los tsim cov fiber ntau, thiab ces ncab, ntxuav, oiling thiab ziab cov spun thawj fiber.
Piv nrog rau txoj kev tsim cov viscose fiber ntau, qhov zoo tshaj plaws ntawm txoj kev spinning no yog NMMO tuaj yeem ncaj qha yaj cellulose pulp, cov txheej txheem ntawm spinning Tshuag tuaj yeem yooj yim heev, thiab tus nqi rov qab ntawm NMMO tuaj yeem ncav cuag ntau dua 99%, thiab cov txheej txheem ntau lawm hardly pollutes ib puag ncig.
Cov qauv morphological ntawm Lyocell fiber ntau txawv kiag li ntawm cov viscose zoo tib yam.Cov qauv ntoo khaub lig yog sib xws, puag ncig, thiab tsis muaj txheej txheej ntawm daim tawv nqaij.Lub longitudinal nto yog du thiab tsis muaj zawj.Nws muaj cov khoom siv zoo tshaj li cov viscose fiber ntau, zoo ntxuav qhov ruaj khov (shrinkage tus nqi tsuas yog 2%) thiab siab noo noo nqus.Nws muaj zoo nkauj luster, mos kov, zoo drapability thiab zoo elegance.
Qhov sib txawv ntawm viscose, modal thiab lessel
(1)Fiber seem
(2)Fiber yam ntxwv
•Viscose fiber ntau
• Nws muaj qhov nqus dej zoo thiab ua tau raws li qhov xav tau ntawm lub cev ntawm tib neeg cov tawv nqaij.Cov ntaub yog mos, du, breathable, tsis yooj yim rau hluav taws xob zoo li qub, UV resistant, xis hnav, yooj yim rau zas xim, ci xim tom qab dyeing, zoo xim ceev, thiab zoo spinnability.Modulus ntub dej yog qhov tsawg, tus nqi shrinkage siab thiab nws yooj yim rau deform.Tes xav tias nyuaj tom qab tso tawm, thiab elasticity thiab hnav tsis kam.
• Modal fiber ntau
• Nws muaj qhov muag muag, ci ntsa iab thiab huv, xim ci thiab zoo xim ceev ceev.Cov ntaub zoo nkauj tshwj xeeb tshaj yog du, cov ntaub saum npoo yog ci thiab ci, thiab cov drapability zoo dua li cov paj rwb uas twb muaj lawm, polyester thiab viscose fibers.Nws muaj lub zog thiab toughness ntawm hluavtaws fibers, thiab muaj cov luster thiab zoo li ntawm txhob lo lo ntxhuav.Cov ntaub muaj wrinkle tsis kam thiab ironing tsis kam, nqus dej zoo thiab huab cua permeability, tab sis cov ntaub tsis zoo.
• Tsawg fiber ntau
• Nws muaj ntau yam zoo heev ntawm ntuj fiber ntau thiab hluavtaws fiber ntau, ntuj luster, du zoo, siab zog, yeej tsis shrinkage, zoo noo noo permeability thiab permeability, mos, xis, du thiab txias, zoo drapability, ruaj thiab ruaj.
(3)Scope ntawm daim ntawv thov
• Viscose fiber ntau
•Cov fibers luv luv tuaj yeem ua kom huv si los yog sib xyaw nrog lwm cov khoom siv textile, uas tsim nyog rau kev ua cov ris tsho hauv qab, tsho sab nrauv thiab ntau yam khoom zoo nkauj.Cov ntaub npuag yog lub teeb thiab nyias, thiab tuaj yeem siv rau quilt thiab cov ntaub zoo nkauj ntxiv rau cov khaub ncaws.
•Modal fiber ntau
•Modale's knitted fabrics yog tsuas yog siv los ua cov ris tsho hauv qab, tab sis kuj yog rau cov khaub ncaws ncaws pob, xws li hnav, tsho, high-end npaj-ua fabrics, thiab lwm yam.
•Tsawg fiber ntau
• Nws npog tag nrho cov teb ntawm textile, txawm nws yog paj rwb, ntaub plaub, txhob lo lo ntxhuav, hemp khoom, los yog knitting los yog weaving, nws muaj peev xwm tsim high-zoo thiab high-end khoom.
