Qhov twg yog qhov zoo dua, nrawm nrawm da dej phuam da dej lossis ntshiab phuam da dej? Cov phuam da dej kom ceev ceev yog cov khoom siv phuam da dej ua los ntawm cov khoom siv superfine, uas tuaj yeem ziab tau sai thiab muaj dej zoo thiab muaj cov dej ua tau zoo. Cov phuam da dej feem ntau siv hauv tsev so thiab tsev so. Lub hauv paus ntsiab lus ntawm cov phuam da dej nrawm-nrawm yog txiav txim siab los ntawm cov qauv tshwj xeeb ntawm cov phuam da dej nrawm-ziab. Cov fiber ntau ntawm cov phuam da dej kom ceev nrawm siv cov txiv kab ntxwv nplaim paj tshiab cov tshuab, uas zoo heev nce capillary qhov sib txawv ntawm cov phuam da dej, yog li txhim kho cov dej nqus ntawm cov phuam da dej. Yog li, cov phuam da dej kom ceev-nrawm yog qhov muaj txiaj ntsig zoo.

Cov phuam da dej kom qhuav sai tuaj yeem nqus dej noo sai sai ntawm lub cev, thiab tom qab ntawd muab tso rau hauv tshav ziab kom ntev li kaum feeb, uas yooj yim heev. Nyob rau tib lub sijhawm, cov phuam da dej nrawm nrawm nrawm muaj kev ua tau zoo, xis nyob, muag muag, kho kom zoo nkauj, thiab kev ua haujlwm siab, uas yog qhov tsim nyog rau kev siv txhua hnub.

Cov phuam da dej ua kom yooj yim-sai yog yooj yim los ntxuav. Lawv feem ntau nqus cov av ntawm cov fibers (dua li sab hauv cov fibers). Tsis tas li ntawd, cov fiber muaj qhov zoo thiab qhov siab ceev, yog li nws muaj lub zog adsorption muaj zog. Tom qab siv, tsuas yog siv dej huv lossis ntxuav me ntsis Tus neeg sawv cev tuaj yeem muab ntxuav tau.

Qhov twg yog qhov zoo dua, nrawm nrawm da dej phuam da dej lossis ntshiab phuam da dej?

1. Cov phuam da dej ntxuav muag yog cov ntaub phuam da dej tshaj plaws nyob rau ntawm kev ua lag luam, feem ntau nrog cov khoob loj. Tom qab ntxuav tas, feem ntau lawv yuav tsum tau qhuav rau ib hnub. Cov phuam da dej kom ceev-nrawm yog paub txog lawv txoj kev ziab kom qhuav. Lub ntsiab tseem ceeb yog tias lawv tuaj yeem qhuav sai sai tom qab siv, uas yooj yim rau kev siv tom ntej.

2. Thaum cov phuam ntxuav muag ntawm cov paj rwb ntshiab siv, tshwj xeeb tshaj yog cov tshuaj fiber ntau hauv cov phuam da dej, cov plua plav, roj, av, thiab lwm yam nyob rau saum npoo ntawm cov khoom uas yuav tsum tau muab so yog ncaj qha nkag rau hauv lub fiber. Tom qab siv tas, nws nyob hauv lub fiber ntau thiab tsis yooj yim tshem tawm. Tom qab lub sijhawm ntev Nws yuav txawm ua rau tawv thiab plam elasticity, uas yuav cuam tshuam rau kev siv ib txwm nyob rau yav tom ntej. Txawm li cas los xij, lub phuam so nrawm-da dej yuav nqus cov av ntawm cov ntaub (tsis nyob sab hauv cov fibers). Tsis tas li ntawd, cov fiber muaj qhov zoo thiab qhov siab ceev, yog li nws muaj zog adsorption muaj peev xwm. Tom qab siv, nws tsuas yog xav tau ntxuav nrog dej los yog xab npum me me.

3. Cov kev pab cuam lub neej ntawm cov zuaj da dej kom ceev ceev thiab cov phuam da dej ntshiab kuj tseem sib txawv. Feem ntau ua nrawm nrawm da dej phuam da dej muaj cov yam ntxwv ntawm siab zog thiab muaj zog tawv, yog li lawv lub neej kev pabcuam tuaj yeem ncav tau ntau dua 4 npaug ntawm kev pab cuam lub neej ntawm cov phuam da dej zoo li qub. Tsis deformed. Tab sis cov phuam da dej ntshiab tsis tuaj yeem ua kom tau cov nyhuv no.
