Koj puas paub qhov txawv ntawm tencel, viscose, modal, lyocell?

1. Lawv yog tag nrho cov regenerated cellulose fibers:

Regenerated cellulose fiber yog tsim los ntawm tej yam ntuj tso cellulose xws li paj rwb linter, ntoo, xyoob, bagasse, reed, thiab lwm yam., los ntawm kev kho tshuaj thiab mechanical ua.

Ntawm cov tshuaj fibers, Viscose, Modal, Lyocell, Triacetate, Polynosic, Cupro thiab Bamboo Pulp fibers thiab cov zoo li yog nyob rau hauv qeb ntawm regenerated cellulose fibers.

2. Viscose thiab Rayon:

Ua ntej tshaj plaws, nws yuav tsum paub meej: Viscose thiab Rayon ob leeg sawv cev rau viscose fibers, tsis muaj qhov sib txawv. Viscose Rayon kuj tseem siv los sawv cev viscose hauv qee qhov chaw.

Hauv Tebchaws Europe, tus qauv ISO tau siv los siv Viscose, thaum US FTC tau siv los siv Rayon, thiab tom qab ntawd kuj tau lees paub ISO's Vicose.

Hauv Suav teb, txhawm rau paub qhov txawv viscose filament thiab staple fiber, qee cov neeg siv Viscose los sawv cev filament, hu ua "rayon", thiab siv Rayon los sawv cev staple fiber, hu ua "rayon".

3. Qauv:

Modal is a regenerated cellulose fiber with high wet modulus High-wet-modulus (HWM). (Saib qeb thib ob hauv Table 1)

Thaum xyoo 1940, Nyiv tau ua tiav cov khoom ntub dej ntub dej modulus viscose staple fiber, hu ua "Toramomen tiger kapok", thiab Tuam Tshoj kuj tsim cov fiber ntau hauv xyoo 1965, hu ua "nplua nuj fiber ntau", hu ua "nplua nuj fiber ntau". ", cov fiber ntau no kov yeej qhov tsis txaus ntawm cov viscose fiber ntau, thiab nws qhov kev ua tau zoo yog ze rau ntawm cov paj rwb fiber ntau, thaum xyoo 1950, cov khoom siv ntub dej ntub dej viscose fiber ntau tau tsim tawm.

Lub npe nrov tshaj plaws yog Austrian Lenzing (Lenzing) tuam txhab. Lawv hu ua lub siab ntub dej modulus regenerated cellulose fiber li Lenzing Modal. Tom qab ntawd, lo lus Modal (Modal) kuj tau tsim los ua ib lub ntsiab lus rau siab ntub dej modulus viscose fiber. Tam sim no ISO Modal cov kev faib fiber ntau twb muaj nyob rau hauv tus qauv, thiab Modal tuaj yeem siv los txheeb xyuas cov ntawv luam tawm.

4. Tencel thiab Lyocell:

Tencel (tencel) yog lub npe ntawm Lyocell fiber ntau tsim los ntawm lub tuam txhab British Acocdis, thiab Suav lub npe yog "tencel" sau npe hauv Suav teb. Thiab Austria Lenzing (Lenzing) lub tuam txhab Lyocell fiber ntau muaj npe: Lenzing-Lyocell.

Hauv xyoo 2004, Austrian Lenzing tau txais Tencel cov chaw muag khoom ntawm Acordis, yog li Tencel kuj tau los ua Lenzing lub cim lag luam.

Lyocell fiber yog lub zog muaj zog regenerated cellulose fiber ntau. (Saib qeb thib peb hauv Table 1) Xyoo 1989, nws tau raug npe los ntawm International Man-made Fiber thiab Synthetic Fiber Committee. Teb Chaws Asmeskas FTC tau ua Lyocell ib qho kev faib tawm raws li viscose uas tuaj yeem siv rau ntawm cov ntawv xov xwm.

5. Qhov txawv ntawm viscose, modal thiab lyocell:

Yuav ua li cas paub qhov txawv viscose thiab modal?

Raws li lub ntsiab lus ntawm BISFA, lub zog thiab ntub dej ntawm modal yuav tsum ncav cuag qhov tseem ceeb, uas yog, lub zog tawg yuav tsum siab dua 3.14cN / dtex, thiab cov qauv ntub dej yuav tsum ntau dua 8.8cN / dtex.

Qhov txawv ntawm modal thiab lyocell:

Ob leeg viscose thiab modal yog regenerated cellulose fibers siv txoj kev viscose, thiab lyocell yog regenerated cellulose fibers siv hnyav txoj kev.

Lub qub yog tsim los ntawm thawj sulfonating cellulose los tsim cellulose sulfonate, uas yuav yaj nyob rau hauv caustic soda, thiab ces desulfurized los ntawm spinning; lub tom kawg yog tsim los ntawm ncaj qha dissolving cellulose nyob rau hauv NMMO thiab spinning.
