'Game-Hloov' Biosynthetic Fibers

'Game-Hloov' Biosynthetic Fibers

Daim ntawv tshaj tawm xyoo 2021 los ntawm Lub Tsev Haujlwm Biomicry hu ua Qhov Xwm ntawm Kev Zam qhia tias ntau dua 60 feem pua ​​​​ntawm cov ntaub ntawv fibers yog cov khoom siv hluavtaws tau los ntawm cov tshuaj petrochemical. Txawm hais tias ua los ntawm cov khoom siv rov ua dua lossis tsis tau kho, cov khoom siv petrochemical tsis yog biodegradable. Tsis tas li ntawd, kev tsim cov fibers no tso tawm cov pa hauv tsev cog khoom, tshuaj thiab lwm yam khoom tsis zoo uas tseem nyob hauv peb cov av, huab cua thiab dej, thiab ib tiam tshiab ntawm biosynthetic polymers thiab fibers tuaj yeem yog qhov kev daws teeb meem rau qhov teeb meem no.

Biosynthetic fibers yog tsim los ntawm biomaterials, nrog rau cov khoom pov tseg, algae, roj castor los yog siv cov paj rwb ntaub, thiab tuaj yeem tsim ua "hloov" rau cov tsoos polyester thiab nylon. Txawm hais tias tsis yog txhua qhov biosynthetic fibers yog biodegradable, lawv tsis txhob siv petrochemical fibers.

Tshiab fiber ntau rau cov khoom siv "dawb carbon".

Tsim los ntawm peb tiam polymers los ntawm cellulosic feedstocks, xws li algae, qab zib pas nrig, straw thiab hemp-uas ntes carbon thaum lawv loj hlob mus-AeoniQ yog tsim los ua piv rau polyester, nylon thiab regenerated cellulosics.

HeiQ hu xov tooj tshiab yog "kev ua si hloov pauv rau tag nrho kev lag luam textile" vim tias nws tuaj yeem rov ua dua tshiab yam tsis muaj kev cuam tshuam zoo. Tam sim no, LYCRA tau dhau los ua nws tus khub peev, thiab cov khaub ncaws high-end Hugo Boss kuj tau tshaj tawm tias nws yuav koom tes nrog HeiQ ntawm nws thawj qhov kev nqis peev uas cuam tshuam txog kev lag luam.

Cellulose filament

Cov kws tshawb fawb ntawm Dunkendorf lub koom haum rau Textile Fibers (DITF) hauv lub teb chaws Yelemees tau tsim ib lub tshuab hu ua HighPerCell (HPC). Lub tshuab siv cov kua ionic los tsim cov fibers txuas ntxiv los ntawm cellulose.

DITF tau siv hemp stalk ua raw khoom rau nws HighPerCell fibers. Cov txheej txheem no yog lwm txoj hauv kev zoo rau cov txheej txheem viscose dav siv. Cov kua ionic tsis muaj tshuaj lom thiab tsis muaj hluav taws kub, thiab tuaj yeem siv tau yooj yim dua tom qab. Spinned los ntawm cellulose raw cov ntaub ntawv xws li ntoo pulp, hemp, thiab chitin (feem ntau yog muab rho tawm los ntawm cws hlwb), HPC fibers yog yus muaj los ntawm siab zog thiab yog haum rau kev siv.

Khaub ncaws thiab khib nyiab ntawm paj rwb los yog cov cellulose regenerated thaum kawg ntawm lub neej tuaj yeem siv tau los ntawm HPC thev naus laus zis. DITF tsis ntev los no tau pib koom tes nrog cov tshiab tsim Technikum Laubholz rau kev tsim tawm ntawm HPC thiab HPCCarbon fibers.

Cov khoom tsim los ntawm HPC fibers yog ob qho tib si recyclable thiab biodegradable, hais tias Dr. Antje Ota, tus lwm thawj coj ntawm DITF Center rau Biopolymer Materials. Cov khaub ncaws thiab pov tseg cov paj rwb lossis cov ntaub qhwv cellulose tuaj yeem siv tau los ntawm HPC technology tom qab siv. DITF tsis ntev los no tau pib koom tes nrog cov tsim tshiab Laubholz Technologies rau kev tsim tawm ntawm HPC thiab HPCCarbon fibers.

Ntiaj teb no carbon capture specialist LanzaTech tau tsim ib tug txheej txheem rau ua textile fibers los ntawm industrial emissions thiab gasified municipal pov tseg.

Cov kab mob hloov cov pa phem rau hauv cov roj thiab tshuaj xws li ethanol. Rau kev tsim cov biosynthetic polyester, cov koom tes nruab nrab India Glycols Ltd. thiab Far Eastern New Century (FENC) siv ethylene glycol los tsim polyester yarns thiab textiles. Txawm hais tias carbon-based polyester fibers tsis biodegradable, cov khaub ncaws tuaj yeem rov ua dua los ntawm tib txoj kev tom qab siv.

"Los ntawm kev rov ua dua cov pa roj carbon monoxide, peb tab tom hloov cov pob txha pob txha roj carbon monoxide tshem tawm hauv av," piav qhia LanzaTech tus thawj coj saib xyuas kev ruaj ntseg Freya Burton. "Cov neeg siv khoom tam sim no tuaj yeem xaiv qhov twg cov pa roj carbon hauv lawv cov khaub ncaws los ntawm. Lub tswv yim yog li tshiab, peb txhua tus tau sim seb yuav ua li cas kom tau txais cov lus hla."

LanzaTech craftsmanship tau ua tiav pov thawj nyob rau hauv capsule collections los ntawm sportswear hom Lululemon thiab thoob ntiaj teb ceev zam khw muag khoom Zara. "Los ntawm kev rov ua dua cov pa roj carbon monoxide, peb tab tom hloov cov pa roj carbon virgin fossil," piav qhia LanzaTech Chief Sustainability Officer Freya Burton. "Tam sim no cov neeg siv khoom tuaj yeem xaiv qhov twg cov pa roj carbon hauv lawv cov khaub ncaws los ntawm. Lub tswv yim yog qhov tshiab, thiab peb txhua tus ua haujlwm hnyav kom tau txais cov lus ntawd mus rau cov neeg siv khoom zoo dua."
