Cov Ntaub Ntawv Ntau Lawm Kom Huv Huv Napkins Yog Qhov Tseem Ceeb

Cov ntaub ntawv tseem ceeb ntawm cov ntaub so tes yog paj rwb, tsis-ntaub npuag, ntawv pulp lossis polymer ntawv tsim los ntawm cov ntaub ntawv saum toj no. Sab tsim yog feem ntau siv los tiv thaiv kev tiv thaiv sab, vim tias nws yuav siv nrog cov phuam huv si Ntawm lub kaum sab xis, nws yooj yim dua rau txhuam tawm ntawm ceg ceg 2113, yog li cov ntaub so tes nrog cov tog hauv dej tau nrov dua nrog cov poj niam.

Cov nplaum ntawm daim ntaub huv si yog qhov tsis zoo rau dej, tuaj yeem khaws cov ntshav ntawm lub cev ntas tawm ntawm cov phuam huv. Nws yog siv los nqus cov ntshav thaum coj khaub ncaws tawm ntawm qhov chaw mos thaum coj khaub ncaws.

Raws li lub teb chaws tus qauv, huv cov ntaub so ntswg tuaj yeem muab faib ua peb pawg raws li cov khoom siv saum npoo av:

1. Cov ntaub so tes qhuav

Xa mus rau huv huv lub ntsej muag txheej txheej ua rau 5261 siv ntau yam perforated zaj duab xis yog thawj daim ntaub huv si, uas yog mas polyethylene, feem ntau hu ua PE zaj duab xis;

2. Cov paj rwb thiab ntaub ntxuav tes huv si

Xa mus rau cov ntaub so ntswg ua los ntawm ntau yam tsis-cov ntaub rau txheej txheej saum npoo ntawm cov ntaub so huv, uas yog polypropylene, feem ntau hu ua PP

3. Cov paj rwb huv si huv si

Xa mus rau cov ntaub so huv ua los ntawm cov paj rwb huv si rau txheej txheej saum npoo ntawm cov ntaub so huv, uas yog cov paj rwb ntshiab tsis-woven ntaub

Cov qauv ntawm cov ntawv huv huv tau muab faib ua cov txheej txheej saum npoo av, nqus cov tub ntxhais thiab cov txheej hauv qab

Cov khaubncaws sab nraud povtseg ntawm cov khoom siv sib txuas nrog kub yaj kua nplaum.

Cov txheej txheej saum npoo yog ib feem uas tau ncaj qha rau daim tawv nqaij. Nws cov khoom 4102 yog mos. Qhov txheej faus thiab cuam tshuam tuaj yeem cuam tshuam qhov rov qab osmosis nyhuv (dryness) ntawm cov ntaub so huv.

PE perforated membrane saum npoo txheej thiab paj rwb xov txheej txheej yog ob yam khoom siv feem ntau. PE nto txheej nrog micro-tsim qauv tuaj yeem ua rau cov ntshav tsis yooj yim rau pom thiab ua rau cov neeg siv ua kom qhuav, tab sis cov khoom siv nyuaj thiab qee cov neeg siv yuav ua rau muaj qhov tsis haum; vim kev txhim kho cov paj rwb khaub ncaws tsim qauv, thiab muaj cov ntaub ntawv perforated thiab cov khoom sib txuas, cov kev lag luam hauv cov xyoo tsis ntev los no tau maj mam siab dua li ntawm PE cov ntawv xaum.

Lub puab txheej yog tsuas yog tsim ntawm paj rwb, tsis yog-ntaub npuag, daim ntawv 1653 pulp lossis cov ntawv sib xyaw ua ke ntawm cov ntawv siab polymer thiab cov nplai siab sib txuas ntawm cov ntawv, siv los nqus tawm ntawm cov ntshav thaum coj khaub ncaws. Tus qauv tsim ntawm sab yog feem ntau siv los tiv thaiv kev tiv thaiv sab, vim tias nws yuav qhia lub kaum ntse ntse nrog lub phuam huv huv lub cev thaum siv, thiab nws yooj yim kom muaj kev sib txhuam nrog rau puab tais. Yog li ntawd, cov ntaub ntaws mos mos sab xis yog qhov nrov dua nrog poj niam. Kev muab rov qab ntawm cov ntawv so huv yog qhov tsis yooj yim rau cov khoom siv thiab tuaj yeem khaws cov ntshav thaum coj khaub ncaws. Hauv 70s thiab 80, cov nplaum rau tus kheej tau tsim los pab txhawb kev txhim kho cov ntawv huv hauv qab ntawm underpants.
