Vim muaj qhov sib txawv ntawm cov paj rwb ntau yam, ib puag ncig kev loj hlob, kev cog thiab kev sau qoob loo, cov paj rwb uas tsim los kuj muaj qhov sib txawv ntawm cov yam ntxwv fiber ntau thiab cov nqi.Ntawm lawv, qhov tseem ceeb tshaj plaws uas cuam tshuam rau qhov zoo yog qhov ntev ntawm cov paj rwb thiab cov txheej txheem sau qoob loo.
Ntev fiber ntau vs. luv fiber ntau paj rwb
Thaum tib neeg xav txog paj rwb, lawv yuav tam sim ntawd xav txog cov paj dawb fiber ntau loj hlob ntawm cov ceg hauv paj paj.Cov qauv dawb no, zoo li paj, hu ua "pob".Nws yog qhov tseeb cov txiv hmab txiv ntoo ntawm tsob ntoo paj rwb.Nws yog cov tsos ntawm paj rwb noob tom qab paj paj yog pollinated thiab tsim paj rwb noob.Lub fuzz ntawm paj rwb noob loj hlob los ntawm daim tawv nqaij ntawm cov paj rwb, maj mam sau rau hauv cov txiv hmab txiv ntoo, thiab thaum kawg tawg cov txiv hmab txiv ntoo ntawm daim tawv nqaij.
Nws yog feem ntau paub tias paj rwb yog tsim tom qab flowering thiab bearing, thiab thaum kawg lub fiber los ntawm paj rwb noob lov lub plhaub ntawm cov txiv hmab txiv ntoo.
Cotton fibers zus ntawm paj rwb noob tau muab faib ua 2.5 mus rau 6.5 hli ntev fiber ntau paj rwb, 1.3 mus rau 3.3 hli ntev fiber ntau paj rwb, thiab 1 mus rau 2.5 hli luv fiber ntau paj rwb raws li lawv ntev.
Feem ntau hais lus, qhov ntev ntawm cov fiber ntau, qhov softer thiab thinner cov ntaub yog vim hais tias cov xov paj yog spun nrog tsawg raug fiber ntau hau, uas yog haum rau ua high-qib khaub ncaws, intimate txaj pw, phuam da dej, thiab lwm yam, thaum lub luv luv. fiber ntau yog, qhov rougher cov xov paj yog spun nrog ntau lub taub hau fiber ntau, yog li nws feem ntau ua rau hnav-resistant thiab ntxhua khaub ncaws txhua hnub.
Hand picking vs. machine picking
Ntxiv rau qhov ntev fiber ntau ntawm paj rwb, txoj kev sau qoob loo kuj tseem cuam tshuam rau cov paj rwb zoo.Cov khoom siv paj rwb qib siab yog yuav luag txhua yam ua los ntawm tes khaws cov paj rwb, tsis yog vim tias cov paj rwb sau los ntawm tes tuaj yeem khaws cov paj rwb tag nrho, tab sis kuj vim cov paj rwb txiv hmab txiv ntoo loj hlob los ntawm qis kawg ntawm cov nroj tsuag.Cov paj rwb sau los ntawm txhais tes tuaj yeem sau rau ntawm qhov kawg ntawm cov nroj tsuag ua ntej, thiab tom qab ntawd cov paj rwb tau sau rau ntawm sab saud dua ib hlis lossis ob zaug tom qab, es tsis yog rub tawm zoo li lub tshuab, uas tsis yog yooj yim rau kev puas tsuaj. fiber, tab sis kuj cov roj Plua plav kuj tuaj yeem paug cov fibers.
Txhawm rau sau paj rwb manually, koj yuav tsum tuav hauv qab ntawm paj rwb tswb nrog tsib ntiv tes kom txo qis kev puas tsuaj rau cov fiber ntau.
Nyob rau hauv cov txheej txheem ntawm kev sau tshuab, cov ceg tuag, cov xuab zeb thiab lwm yam impurities yuav muab sib xyaw rau hauv paj rwb, uas yuav ua rau cov fiber ntau puas.
