1.Txoj kev sawv cev

• Mev suav (NM) yog hais txog qhov ntev hauv meters ntawm ib gram ntawm yarn (lossis fiber ntau) ntawm kev muab ya raws.

Nm = l (chav tsev m) / g (chav tsev g).

• Nti suav (nev) nws hais txog pes tsawg 840 yards ntawm paj rwb paj weighing 1 phaus lauj kaub (453.6 grams) (1 yard = 0.9144 meters) ntev.

Ne = l (chav tsev y) / {g (unit p) x840)}.

Lub nti suav yog qhov ntsuas ntsuas ntsuas ntawm lub teb chaws qub qub txheem rau cov thickness ntawm paj rwb paj, uas tau hloov los ntawm tus lej tshwj xeeb. Yog tias 1 phaus ntawm cov xov paj muaj 60 840 yards ntev, cov yarn fineness yog 60 nti, uas tuaj yeem sau tau raws li 60s. Cov sawv cev thiab kev xam txheej txheem ntawm cov nti suav ntawm cov strands yog tib yam li cov lej nruab nrab.

2.Taag-Ntev Zog

Hais txog qhov hnyav ntawm qee qhov ntev ntawm fiber ntau lossis xov paj.

Tus me dua tus nqi, cov xov paj. Nws cov chav ntsuas suav suav nrog tus lej tshwj xeeb (NTEX) thiab Denier (Nden).

• Ntex, lossis TEX, hais txog qhov hnyav nyob rau hauv grams ntawm 1000 ntev ntev fiber ntau lossis xov ntawm cov dej noo uas tau ua ntej, tseem hu ua tus lej.

NTex = 1000g (Chav G) / L (Chav Tsev M)

Rau ib lub xov paj, tus lej Tex tuaj yeem sau tau rau hauv daim ntawv ntawm "18 Tex", uas txhais tau tias thaum cov xov paj yog 1000 hnyav yog 18 gram. Tus naj npawb ntawm cov strands yog sib npaug rau cov naj npawb ntawm ib cov xov paj huam los ntawm tus naj npawb ntawm cov strands. Piv txwv li, 18 x 2 txhais tau tias ob lub yarns ntawm 18 tex yog pled, thiab lub plied, thiab cov plied fineness yog 36 Tex. Thaum tus naj npawb ntawm ib cov xov uas ua rau cov strands sib txawv, tus naj npawb ntawm cov strands yog qhov suav ntawm txhua cov xov ntawm txhua cov xov.

Rau cov fibers, tus naj npawb ntawm tex yog loj heev, thiab nws feem ntau qhia hauv DecreX (NDTEX). Lub DecreX (Chav Tsev DTEX) yog hais txog qhov hnyav nyob rau hauv grams ntawm 10000m ntev fiber ntawm ib qho kev muab ya raws.

NDTEX = (10000g × GK) / L = 10 × NTEX

• Denier (Nden) yog qhov tsis lees paub, uas yog hais txog qhov hnyav nyob rau hauv grams ntawm 9000m ntev fibers lossis yarns ntawm lub npe tau ua ntej.

Nden = 9000g (Chav G) / L (Chav Tsev M)

Denier tuaj yeem qhia tau raws li: 24 Denier, 30 txwv tsis pub thiab lwm yam. Tus denier ntawm cov strands yog qhia nyob rau hauv tib txoj kev uas yog tus lej tshwj xeeb. Denier feem ntau yog siv los nthuav qhia lub txiaj ntsig ntawm cov khoom noj muaj kuab lom lossis tshuaj fiber ntau.

3.Qhov kev sib tw

Cov ntaub ntawv suav yog txoj hauv kev hais tawm xov xwm, feem ntau qhia ua ke ntawm 840 vaj ntxwv

Feem ntau, thaum ua cov ntaub ua lag luam, ob peb cov lus tshaj lij feem ntau koom tes nrog: suav, ntom ntom. Yog li dab tsi cov ntaub ua tiav cov ntaub ua kom cov ntaub thiab qhov ntom muaj nyob rau ntawm cov ntaub?

Qee tus neeg tseem tuaj yeem nyob rau hauv lub puzzle.Qhov lwm tsab xov xwm yuav mus rau hauv kev nthuav dav.
