Nruam refinement ntawm raw khoom technology
In the development of bio-based chemical fibers, the importance of bio-based raw material innovation is becoming more and more significant, and its development technology is becoming more and more refined, from simple primary processing and utilization to gene modification and expression combined with bioengineering technology, to purification, separation and reprocessing and utilization of microscopic chemical components. The utilization of raw materials is becoming more and more diversified, from the development of traditional cellulose and lignin components to the utilization of biological active ingredients, such as the supercritical extraction of lavender, Wormwood, mint leaves, apocellae, torreya grandis and other plant active ingredients, adding "flavoring" elements to bio-based chemical fibers.
Peb yuav xyuam xim ntau dua rau ntsuab thiab qis - carbon kev loj hlob
Bio-raws li fiber ntau muaj qhov zoo ntawm kev txhim kho los ntawm qhov chaw, thiab nws yog lub neej yav tom ntej kom paub txog ntsuab thiab qis -carbon kev loj hlob nyob rau hauv tag nrho lub neej voj voog ntawm lub hauv paus no. Thawj yog ntsuab kev loj hlob ntawm raw khoom ua technology. Kev tsim cov khoom siv raw ntawm cov khoom siv rov ua dua tshiab xws li viscose fiber ntau siv tshuaj kho mob, acid-base hydrolysis, siab - kub ua noj thiab lwm yam txheej txheem los ua pulping, uas feem ntau ua rau muaj kev puas tsuaj rau ib puag ncig. Yog li ntawd, kev txhim kho kom zoo, muaj kuab paug-dawb thiab qis- tus nqi pretreatment txhais tau tias yuav yog lub ntsiab kev taw qhia ntawm cellulose raw khoom pretreatment yav tom ntej. Siv txoj kev fermentation microbial los npaj siab - purity cellulose lov los ntawm ib txwm lub tswv yim ntawm kev cia siab rau cov nroj tsuag uas muaj lub voj voog loj hlob ntev los npaj cellulose fibers, thiab txhim kho cov thev naus laus zis ntawm kev npaj siab - purity cellulose raw cov ntaub ntawv raws li ntawm microbial system, uas tuaj yeem tshem tawm tag nrho cov pa phem hauv cov txheej txheem ntawm kev npaj cov khoom siv raw thiab muaj qhov zoo ntawm kev tiv thaiv ib puag ncig ntsuab.
Thib ob, kev sib cais ntawm lub cev ntawm lignin, hemicellulose thiab cellulose los ntawm ultrasonic assisted steam explosion method yog ib qho ntawm cov qauv ntawm cellulose raw khoom kho rau yav tom ntej. Hais txog cov khoom ntsuab, peb tsom mus rau kev tsim bio-raws li cov fibers thiab cov khoom xws li cov xim ntawm cov kua nyoos, stain kuj thiab yooj yim tu, zoo zoo khaws cia (dawb ironing), sov thiab txias, kom cov khoom tuaj yeem ua tau qis dua -carbon thiab ib puag ncig tus phooj ywg nyob rau hauv cov txheej txheem ntawm kev siv, kev saib xyuas lossis qhov kawg ntawm kev pab cuam lub neej.
Cov khoom tsim muaj kev tshaj lij
Bio-raws li regenerated fibers tau maj mam nthuav tawm los ntawm ib txwm viscose thiab Lyocell rau seaweed fiber thiab chitosan fiber. Bio-raws li hluavtaws fibers tau nthuav dav los ntawm bio-raws li PTT thiab PLA fibers mus rau lwm yam bio-raws li polyester (PHB, PBT, PET, thiab lwm yam), bio- Raws li polyamides (PA6, PA66, PA56, PA69, PA610), bio-raws li polyethylene, bio-raws li polypropylene, bio-raws li PVC, bio-raws li TPU thiab hmoov txhuv nplej siab-raws li polymers, thiab lwm yam. Nyob rau hauv cov txheej txheem no, kev loj hlob ntawm bio{15}}raws li monomer ntau yam plays lub luag hauj lwm irreplaceable.
Nrog rau kev txhim kho txuas ntxiv ntawm qib ua fiber ntau, kev txhim kho ntawm bio-cov ntaub ntawv fiber ntau yuav tsum tsis tsuas yog them sai sai rau nws txoj kev txhim kho kom zoo, tab sis kuj yuav tsum tau muab nws txoj haujlwm tshiab. Tag nrho coj mus rhaub cov yam ntxwv ntawm kev sib txawv ntawm cov roj ntsha sib txawv ntawm cov hluavtaws fibers, muab kev ua si tag nrho rau qhov zoo ntawm nws cov kev ua tau zoo, docking apparel, tsev textile, tsheb sab hauv trim, cov kev xav tau ntawm cov ntawv thov sib txawv xws li cov khoom kho mob, kev tshaj lij, kev tsim qauv. , tsim ib lub monomer, kev lag luam tshwj xeeb, txoj kev tshiab, mus rau txoj kev zoo thiab kev sib koom ua lag luam.
