Leliphi icandelo le-cotton livelisa isellulose emsulwa?

Intshayelelo kwi-cotton kunye nesellulose

Umqhaphu, i-fiber yendalo ethathwe kwisityalo sekotoni, sibunjwe ikakhulu yi-sellulose. Iseli Extracting pure cellulose from cotton involves separating the cellulose fibers from other components of the cotton plant, such as lignin, hemicellulose, and pectin.

Ukuqonda i-anatomy ye-Cotton City kubaluleke kakhulu kwi-seluplose. Iifibhori zeCotton zizikolo zembewu, ezikhula kwiiseli ezinkulu ze-cottonseed. Ezi fibers ziquka ikakhulu i-sellulose, kunye nezixa ezincinci zeeproteni, ii-waxes, kunye neswekile. Iintsinga zekotoni zikhula kwiibhotile, ezizikhusela iicaphu ezikhusela imbewu.

Inkqubo yokukhuphela iselfowuni

Ukuvuna: Inkqubo iqala ngokuvuna i-botton evuthiweyo kwi-botton yezityalo zekotoni. Ukuvunwa koomatshini yeyona ndlela ixhaphakileyo, apho oomatshini basusa iirull kwizityalo.

UGuinning: Emva kokuvunwa, umqhaphu uphoxekile, apho imbewu yahlulwe khona kwiintsinga. Le nkqubo ibandakanya ukudlulisa umqhaphu ngoomatshini abaseGin esusa imbewu evela kwiintsinga.

Ukucocwa: Nje ukuba zihlukane nembewu, i-fibers yekotoni ihlambulula ukuze isuse ukungcola ezinje ngokungcola, amagqabi, kunye nezinye izinto zesityalo. Eli nyathelo liqinisekisa ukuba i-seluped ye-seluped bubunyulu obuphezulu.

Ukuhamba kweKhadi: UkuKhathwa kweKhadi yinkqubo yoomatshini ehambelana ne-fibers yekotoni kwiwebhsayithi emfutshane. Isusa nayiphi na into engcolileyo kwaye ilungelelanisa iintsinga zokulungiselela ukuqhubekeka.

I-fibers: Iintsinga zekotoni ziqukethe ukungcola kwendalo ezinjenge-waxes, ii-pectan, kunye ne-hemicelluloses, ngokudibeneyo zibizwa ngokuba "gum." Igrimume ibandakanya ukunyanga i-fibers yekotoni kunye nezisombululo ze-alkaline okanye i-enzymes yokususa ezi zinto zingaqhelekanga.

I-Bleaching: I-Bleach linyathelo lokukhetha kodwa lihlala lisetyenziswa ukuqhubela phambili ngeentsinga zeselfowuni kwaye iphucule ubumhlophe babo. Iiarhente ezinzulu ezahlukeneyo ezinjenge-hydrogen peroxide okanye i-chlorine derivetives zinokusetyenziswa kule nkqubo.

I-Perrince: Ingqondo ibandakanya ukunyanga i-fibers yeselselose ngesisombululo seCaustic, iSodium Hydroxide. Le nkqubo inyusa amandla entsizi, i-luster, kunye nobubele kwii-Dyes, zenza ukuba balungele izicelo ezahlukeneyo.

I-Acid Hydrolysis: Kwezinye iimeko, ngakumbi kwiinjongo zokwenza imizi-mveliso, i-Acid Hydrolysis inokuqeshwa ukuze iqhubekeke i-selsulose ibe ngamancinci, ngakumbi amasuntswana afanayo. Le nkqubo ibandakanya ukunyanga i-seluplose nge-dilsese acid iphantsi kweemeko ezilawulwayo kwi-hydrolyze i-glycosidic binds, ivelise i-nanocrystals.

Ukuhlamba kunye nokomisa: Ukulandela unyango lwekhemicamicamicamicamicamicamicali, iintsinga zeselselose zihlanjululwe ngokupheleleyo ukuba zisuse nayiphi na imichiza okanye ukungcola. Emva koko, iintsinga zomiswa kumxholo wokufuma.

Izicelo ze-selsulose emsulwa

I-selsulose emsulwa ifunyenwe kwikotoni ifumana izicelo kumashishini ahlukeneyo:

Iimbaleki: Iintsinga zeselselose zixhaphakile kwimitya kwaye zihonjiswe kwilaphu lempahla yokunxiba, ikhaya, kunye nezicelo zemveliso.

Iphepha kunye nePhepha lePhepha lePhepha: I-Seleulose yinxalenye ephambili yephepha, iphephabhodi, kunye neemveliso zekhadibhodi.

I-biofuels: I-Seleculose inokuguqulwa ibe yi-biofuel enjenge-ethanol ngokusebenzisa iinkqubo ezinjenge-enzymatic hydrolysis kunye nokubila.

Ukutya kunye nemizi-mveliso yamachiza: Iiseli zeselselose zisetyenziswa njengamanzi amakhulu, izilo, kunye ne-emulsiber ekutyeni nakwimveliso yamayeza.

I-cosmetics: Ii-Selesese Schorivetives zisetyenziswa kwi-cosmetics kunye neemveliso zononophelo zobuqu zokuzibamba kwabo kwaye zizimisele iipropathi.

Ukukhupha isellulose ecocekileyo kwikotoni kubandakanya uthotho lweenkqubo zoomatshini kunye neekhemikhali ezijolise ekuphumeni kweentsinga zeseluplose ezivela kwezinye izinto zesityalo somqhaphu kwaye sizihlambulule. Ukuqonda i-anatomy yesityalo somqhaphu kunye nokuqesha iindlela ezifanelekileyo ezinjengokuphambana, ukukhukhuma, ukugqobhoza, kunye nokuqhubela phambili kubalulekile ekufumaneni i-selsulose ekumgangatho ophezulu. I-selsulose emsulwa ifunyenwe kwi-cotton ineendlela ezahlukeneyo kumashishini, isuka ezivela kwii-bipermang kwi-biofuels kunye nezixhobo zendalo nezixabisekileyo.
