Muaj ntau txoj hauv kev los ua hydrophilic Nonwoven npuag

Hydrophilic yog ib txoj kev kho mob rau cov ntaub tsis woven. Feem ntau, nonwoven fabrics yog dej resistant. Raws li qhov kev thov, cov neeg tsim khoom ua cov kev kho mob ua ntej lossis tom qab kev kho mob ntawm cov ntaub tsis muaj ntaub, thiab ob txoj kev kho mob ncaj qha cuam tshuam rau cov nyhuv hydrophilic. Hnub no kuv qhia koj txog qhov sib txawv ntawm kev kho mob ua ntej thiab tom qab kev kho mob ntawm hydrophilic non-woven fabrics. Kuv vam tias nws yuav pab tau koj!

Ua ntej ntawm tag nrho cov, cov ntaub tsis-woven yog cov tshuaj tiv thaiv dej, hydrophilic non-woven fabrics thiab dej tsis-woven fabrics yog opposite. Vim tias cov ntaub tsis-woven nws tus kheej tsis yog hydrophilic, nws yog ib qho tsim nyog yuav tsum tau ntxiv hydrophilic masterbatch los yog ntxiv cov roj hydrophilic los txhim kho qhov sib piv ntawm hydrophilic non-woven npuag, uas yog los txhim kho kev ua haujlwm ntawm hydrophilic.

Hydrophilic non-woven npuag yog tus cwj pwm los ntawm lub peev xwm nqus dej, uas yog, hydrophilic ratio, hydrophilic ceev, hydrophilic lub sij hawm, hydrophilic lub sij hawm siv tau thiab lub sij hawm. Txhawm rau txhim kho hydrophilicity ntawm non-woven fabrics, nws yog feem ntau los txhim kho qhov ntub dej kom ua tiav lub hom phiaj ntawm hydrophilicity. Tam sim no, kev tsim cov txheej txheem ntawm hydrophilic non-woven fabrics tuaj yeem yog los ntawm kev hloov kho lub cev thiab tshuaj lom neeg: kev hloov kho (piv txwv li ua ntej spinning) thiab kev hloov kho deg (xws li tom qab spinning).

1.Blending kev hloov kho (kev hloov kho ua ntej spinning)

Raws li lub sijhawm sib txawv ntawm kev hloov kho additives, nws tuaj yeem muab faib ua tus qauv masterbatch, tag nrho cov txheej txheem granulation thiab txoj kev txhaj tshuaj ua ntej spinning.

1. Hom masterbatch feem ntau

Qhov no yog ib txoj hauv kev tseem ceeb rau cov tuam txhab uas tsis yog-woven los tsim hydrophilic non-woven fabrics. Hydrophilic masterbatch yog tsim los ntawm ntau hydrophilic additive los ntawm masterbatch chaw tsim tshuaj paus, thiab ces sib tov nrog PP rau yaj spinning ntaub, uas yog hydrophilic non-woven npuag.

Qhov zoo: kev tsim khoom yooj yim, tsis tas yuav ntxiv cov khoom siv, thiab tsim rau cov khoom me me. Tsis tas li ntawd, nws hydrophilic persistence muaj zog.

2. Tag nrho granulation

Hydrophilic PP hais tau npaj los ntawm cov ntsia hlau extrusion granulation, thiab tom qab ntawd yaj spun rau hauv daim ntaub.

qhov zoo; Kev ua tau zoo, cov nyhuv ruaj khov, daim ntaub tuaj yeem siv dua.

3. Txhaj tshuaj ua ntej tig

Lub hydrophilic polymer tau ncaj qha ntxiv rau hauv lub ntsiab ntsia hlau ntawm cov ntaub tsis-woven thiab tov nrog PP yaj rau ncaj qha spinning.

Qhov zoo: cov nyhuv kav ntev, daim ntaub tuaj yeem siv tau ntau zaus

2.Surface hydrophilic xov (kev hloov kho tom qab spinning)

Hydrophilic xov yog ib qho yooj yim, siv tau thiab tus nqi qis los ua cov ntaub ntawv hydrophilic tsis-woven. Cov txheej txheem thev naus laus zis tseem ceeb yog raws li hauv qab no:

Ntawm kab spunbonded kub-kuav los tiag tsis-woven fabrics - yob txheej los yog txau hydrophilic tus neeg saib xyuas - infrared los yog kub cua tshuab - winder - hydrophilic xov non-woven membrane.

Qhov zoo: tsis muaj teeb meem spinnability, ceev hydrophilic nyhuv, kev ua haujlwm siab thiab tus nqi qis ntawm cov ntaub tsis-woven, uas yog 1 / 2-1 / 3 ntawm tus nqi ntawm cov qauv masterbatch. Haum rau kev tsim khoom loj.
