Kev lag luam tshuaj lom neeg tsim ntau yam polymers. Ib tug ntawm lawv, hu ua cellulose, yog tau thaum lub sij hawm cov tshuaj tiv thaiv ntawm ntoo fiber nrog acidic los yog alkaline reagents thiab tom qab kev kho cua sov. Qhov tshwm sim ntawm cov txheej txheem yog fibers haum rau cov xov paj filaments. Cov khoom woven los ntawm lawv yog hu ua rayon.
Kev lag luam tsim tawm ntawm cellulose pib ua ntej nws cov qauv tshuaj raug txiav txim siab. Cellophane - pob tshab polymeric ntawv rau ntim - tau tsim nyob rau hauv Fabkis nyob rau hauv lub xyoo pua 19th. Nyob rau hauv lub USSR, technologies siv cov khoom ntawm cellulose tsim sai heev nyob rau hauv lub peb caug xyoo.
Txhua tus paub tias cov ntaub siv rau kev txiav yog hluavtaws thiab ntuj. Niaj hnub no, naturalness muaj nuj nqis heev, tab sis nws tsis yog tas li. Cov neeg siv khoom ntawm paj rwb, linen lossis ntaub plaub yog ntau dua li cov nylon lossis polyester, txawm hais tias thaum lub sijhawm pom ntawm cov khoom sib xyaw, nws ua rau muaj kev tawg tiag tiag, ua tsaug rau cov khoom zoo tshaj plaws rau cov neeg siv khoom ntawm plaub caug thiab tsib caug: txawv tshaj plaw. brightness thiab durability ntawm cov xim, muaj peev xwm tsiswrinkle, yooj yim ntawm kev ntxuav thiab ziab sai. Txawm li cas los xij, tib neeg tsis ntev los no pom tias lawv tseem muaj kev zoo siab dua hauv tej yam ntuj tso. Cov txheej txheem tseem ceeb uas txiav txim siab qhov kev nplij siab ntawm cov khaub ncaws yog nws cov hygroscopicity thiab muaj peev xwm dhau ntawm huab cua, uas yog, qhov cua.
Thiab yog li ntawd, tus neeg yuav khoom khaws lub tsho uas nws nyiam thiab nyeem ntawm daim ntawv: ib puas feem pua viscose. "Dab tsi yog ntaub?" nws xav tias. Raws li lub npe qhia, nws tsis zoo li ntuj. Tej zaum nws yog hluavtaws? Tsis yog, cov ntaub no tsis muaj dab tsi cuam tshuam nrog fibers tau los ntawm cov khoom siv roj av. Thiab tus nqi, raws li txoj cai, tsis yog me me - cov khoom polyester feem ntau pheej yig dua. Tab sis nws tsis yog paj rwb los yog txhob lo lo ntxhuav, tab sis ib yam dab tsi nyob rau hauv nruab nrab ntawm kov …
Qhov laj thawj no yog qhov laj thawj zoo. Viscose yog cov khoom siv dag zog, tab sis tsis yog hluavtaws. Nws yog tsim los ntawm fiber ntau fiber ntau thiab khaws nws cov txiaj ntsig zoo, uas ua rau kev nplij siab hnav. Nws zoo kawg nkaus absorbs noo noo thiab muab cua microcirculation, uas yog li tsim nyog rau nourishing daim tawv nqaij pores nrog oxygen.
Nws kuj yog qhov qab ntxiag rau qhov kov, ua tsaug rau nws cov silkiness, ntuj viscose pleasantly txias rau hnub kub. Thiab tus nqi, zoo, yog vim qhov nyuaj manufacturing technology. Yog li, feem ntau, cov khoom zoo yog viscose. Dab tsi ntawm cov ntaub, thiab nws nyob li cas ntawm kev ua haujlwm ntev? Hmoov tsis zoo, nws yog qhov tseem ceeb tshaj rau kev ntxhua khaub ncaws thiab hnav tsis tshua muaj zog dua li tib lub paj rwb. Tab sis qhov tsis zoo no yog tag nrho los ntawm nws txoj kev zoo nkauj. Cov poj niam lub ris tsho hauv qab ua los ntawm viscose zoo litsis muaj tsawg impressive tshaj li ib tug txhob lo lo ntxhuav robe, thiab cov txiv neej lub Hawaiian tsho tsuas yog ib lub tsiab peb caug rau lub qhov muag. Nws yog qhov zoo tshaj plaws los ntxuav cov khoom ntawm tes, thiab yog tias koj siv lub tshuab ntxhua khaub ncaws tsis siv neeg, ces koj yuav tsum xaiv hom maj mam tshaj plaws, txwv tsis pub cov npoo ntawm cov ntaub yuav raug kev txom nyem, thiab nws yuav pib "crumble".
Hauv kev tsim cov ntaub ntawv textile, nws tsis yog qhov tsis yooj yim los ua ke ntau yam khoom: ntuj, hluavtaws thiab hluavtaws fibers. Viscose tsis muaj qhov zam. Dab tsi ntawm cov ntaub koj tau txais thaum koj sib tov nrog paj rwb? Cov khoom zoo heev, sib txuas ua kom zoo nkauj thiab tactile zoo ntawm ob qho khoom siv. Nws yuav tiv taus ntau dua vim muaj paj rwb cov tshuaj antioxidants ntuj nyob rau hauv nws cov muaj pes tsawg leeg thiab tib lub sij hawm silky, nrog me ntsis sheen thiab tints.
Raws li txoj cai, cov neeg siv khoom kuj xav paub seb cov viscose tuav cov xim zoo li cas. Dab tsi ntawm cov ntaub yog qhov no, uas nyob rau tib lub sijhawm muaj cov xim zoo li no thiab tsis tso? Tej zaum nws tseem yog hluavtaws? Tsis yog, nws tsis yog hais txog qee yam tsis zoo, tab sis dua txog kev siv tshuab. Cov dye yog nkag mus rau hauv cov xov twb nyob rau theem ntawm nws tsim, yog li nws yog ib feem ntawm cov qauv molecular ntawm cov ntaub, thiab cov khoom ntuj niaj hnub yog thawj woven thiab ces dyed.
Cov khoom siv yog ntuj, txawm tias tsim los, yog, tau kawg, viscose. Dab tsi ntawm ntaub thiab dab tsi yog nws cov khoom, tej zaum koj twb to taub lawm. Cov fibers uas ua rau nws muaj cov qauv cellular, yog li koj yuav tsum tsis txhob ntshai tias lub teeb khaub ncaws ua los ntawm cov khoom siv no yuav tsim cov nyhuv tsev cog khoom thiab ua rau txhua yam tsis xis nyob.

Dab tsi yog briquette, nws yog dab tsi, qhov zoo thiab qhov tsis zoo ntawm roj
Nws nyuaj rau nrhiav lwm txoj hauv kev yooj yim rau cov pa roj uas yog qhov cua sov hauv tsev. Tab sis nws tsis yog ib txwm ua tau los ua cov txheej txheem tsim nyog, yuav cov roj boiler thiab lwm yam khoom siv. Ntau tus xav paub txog dab tsi tuaj yeem siv los ua kom sov ib lub tsev ntiag tug, tshwj tsis yog cov taws tswm ciab, dab tsi tuaj yeem siv tau, ntxiv rau cov tsoos roj. Yav dhau los, ntau cov pov tseg tau muab pov tseg thiab pov tseg. Niaj hnub no, ntawm ntau nag hmo cov neeg ua lag luam "cov khib nyiab" "ua tau nyiaj", tau txais txiaj ntsig zoo rau ib puag ncig thiab cov pej xeem
