Dab tsi yog raw paj rwb fiber?
Raw paj rwb fiber ntau yog ib hom fiber ntau uas tau muab los ntawm cov paj rwb, kev tshawb fawb hu ua Gossypium. Nws yog dav paub thiab siv vim nws ntau yam xwm thiab ntau yam khoom uas yuav ua tau los ntawm nws. Raw paj rwb fiber ntau plays lub luag haujlwm tseem ceeb hauv kev lag luam textile vim nws tau hloov mus rau ntau hom los tsim cov ntaub, xov, thiab lwm yam khoom siv paj rwb.
Keeb kwm ntawm Raw Paj Rwb Fiber
Cov paj rwb cog tau ntseeg tias muaj keeb kwm nyob hauv thaj chaw sov thiab subtropical ntawm lub ntiaj teb, xws li Central America, India, Africa, thiab Mexico. Nws tau raug cog rau ntau txhiab xyoo rau nws cov mos mos, fluffy fibers, uas tau ua tib zoo sau thiab ua tiav los tsim cov paj rwb siv tau.
Cotton Harvesting
Cov txheej txheem ntawm kev sau cov paj rwb fiber ntau muaj ob peb kauj ruam. Ua ntej, paj rwb nroj tsuag yog zus nyob rau hauv loj teb, feem ntau hu ua paj rwb teb. Cov teb no xav tau tej yam kev mob tshwj xeeb, suav nrog qhov kub thiab txias, tshav ntuj txaus, thiab dej txaus rau kev loj hlob zoo.
Thaum cov paj paj loj hlob tuaj, lawv cov paj tawg thiab nws thiaj li loj hlob mus rau hauv paj rwb bolls. Cov bolls no muaj cov paj rwb nyoos fiber ntau uas peb siv. Kev sau qoob loo feem ntau tshwm sim thaum lub bolls tau tag nrho matured thiab tig xim brownish. Nyob rau theem no, cov paj rwb fibers hauv lub bolls yog npaj txhij mus sau.
Txhawm rau khaws cov paj rwb, cov neeg ua liaj ua teb siv cov tshuab tshwj xeeb lossis cov txuj ci tshwj xeeb. Cov tshuab maj mam tshem cov paj rwb los ntawm bolls, thaum handpicking yuav manually plucking paj rwb fibers. Tom qab ntawv xaiv cov paj rwb fiber ntau yog sau thiab thauj mus rau cov chaw ua haujlwm.
Ua Raw Paj Rwb Fiber
Ua raw cov paj rwb fiber ntau yog txheej txheem intricate uas muaj ntau theem. Cia peb tshawb xyuas cov kauj ruam tseem ceeb:
1. Kev Tu: Cov paj rwb nyoos fiber ntau feem ntau muaj impurities xws li av, nplooj, noob, thiab lwm yam khib nyiab. Txhawm rau tshem tawm cov impurities, cov paj rwb tau dhau los ua txheej txheem hu ua ginning. Thaum lub sij hawm ginning, paj rwb yog dhau los ntawm lub tshuab uas cais cov fiber ntau los ntawm cov noob thiab lwm yam khoom tsis xav tau.
2. Carding: Thaum cov paj rwb nyoos tau ntxuav, nws yog carded los ua kom cov fibers thiab tshem tawm cov impurities seem. Carding yog ua tiav siv lub tshuab hu ua lub tshuab carding. Cov txheej txheem no ua kom ntseeg tau tias cov paj rwb fibers tau zoo sib xws thiab npaj rau kev ua haujlwm ntxiv.
3. Spinning: Cov kauj ruam tom ntej yog spinning, qhov twg daim carded paj rwb fibers hloov dua siab tshiab rau hauv xov los yog xov. Spinning tuaj yeem ua tiav siv ntau txoj hauv kev, suav nrog lub nplhaib spinning, rotor spinning, thiab qhib-kawg spinning. Cov txheej txheem no sib txawv raws li kev ua tau zoo, xov paj zoo, thiab kev ua haujlwm ceev.
4. Weaving los yog Knitting: Tom qab spinning, cov paj rwb xov paj yog npaj txhij rau woven los yog knitted los tsim fabrics. Weaving muaj interlacing lub lengthwise (warp) thiab crosswise (weft) yarns ntawm ib tug loom los tsim ib tug woven ntaub. Knitting, ntawm qhov tod tes, koom nrog kev sib txuas ntawm cov xov paj los tsim cov ntaub knitted.
Kev siv ntawm Raw Paj Rwb Fiber
Raw paj rwb fiber ntau yog incredibly ntau yam, thiab nws daim ntawv thov txuas mus rau lub textile kev lag luam. Nov yog qee qhov kev siv tseem ceeb ntawm cov paj rwb fiber ntau:
1. Textiles: Feem ntau siv cov paj rwb fiber ntau yog nyob rau hauv cov khoom siv textiles.

Cov paj rwb-raws li ntaub yog xis hnav thiab haum rau ntau yam huab cua.
2. Cov khoom siv kho mob thiab kev nyiam huv: Cov paj rwb nyoos fiber ntau kuj siv rau hauv kev tsim khoom siv kho mob thiab tu cev. Nws yog siv los tsim cov ntaub qhwv, paj rwb, hnav khaub ncaws phais, thiab cov khoom siv tu cev, xws li cov ntaub so ntswg thiab tampons.
3. Cov Khoom Siv Hauv Tsev: Cov ntaub paj rwb yog nrov rau kev tsim cov khoom vaj khoom tsev xws li ntaub, ntaub pua tsev, thiab ntaub pua chaw. Lub ntuj tsim ntawm paj rwb, nrog rau nws cov softness thiab hypoallergenic xwm, ua rau nws yog ib qho kev xaiv haum rau tsev textiles.
4. Cov ntawv thov kev lag luam: Raw paj rwb fiber ntau pom cov ntawv thov hauv ntau yam kev lag luam. Nws yog siv nyob rau hauv zus tau tej cov lim, ropes, industrial xov, thiab txawm nyob rau hauv kev tsim cov ntawv thiab banknotes.
5. Handicrafts thiab Art Projects: Raw paj rwb fiber ntau yog cov khoom siv tseem ceeb rau ntau yam khoom siv tes ua thiab kos duab. Cov kws kos duab thiab cov neeg ua haujlwm siv paj rwb fiber ntau los tsim cov qauv macrame, cov duab puab, thiab lwm yam khoom siv textile-based artworks.
Kev Sib Tw thiab Sustainability
Txawm hais tias nws muaj koob meej, kev tsim cov paj rwb nyoos fiber ntau ntsib qee qhov teeb meem, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm sustainability thiab ib puag ncig cuam tshuam. Kev ua liaj ua teb paj rwb feem ntau suav nrog kev siv tshuaj tua kab, tshuaj tua kab, thiab chiv, uas tuaj yeem ua rau ib puag ncig thiab tib neeg noj qab haus huv. Txawm li cas los xij, muaj kev paub ntau ntxiv thiab kev thov rau cov txheej txheem kev tsim cov paj rwb organic thiab ruaj khov.
Organic paj rwb txoj kev ua liaj ua teb txhawm rau txo qis kev siv tshuaj thiab txhawb kev coj ua ib puag ncig.
