7. Kusungunuka: Ikhoza kusungunuka m'madzi mumtundu uliwonse, ndipo imatha kupanga colloids ndi ma asidi ena;
8. Kugwirizana: Itha kugwiritsidwa ntchito limodzi ndi othandizira ambiri a nsalu;
9. Kukhazikika kwa Bath: Kukhazikika pakusamba kwa maola opitilira 5.

Processing Makhalidwe

A) Nsalu za cellulose fiber

Makhalidwe otsatirawa atha kupezeka pogwiritsa ntchito utomoni ndi YT kuphatikiza kupanga zinthu zolimba za cellulose:

1. Mkulu makwinya ndi kuchepera kukana, cholimba ndi kuchapa;
2. Chokhalitsa makina processing ntchito pambuyo kutsuka;
3. Kukakamira komwe kumachitika chifukwa cha utomoni kumachepetsedwa, ndipo kumatsutsana bwino ndi chlorine;
4. Kumawonjezera kuchapa kwamitundu yambiri yolunjika;
5. Kumawonjezera kukana kwa hydrolysis chifukwa cha asidi kapena kutulutsa zinthu za asidi;
6. Sasintha mtundu chifukwa cha kutentha kutentha;
7. Otsika kwambiri otsalira formaldehyde pamwamba pa nsalu, kuchepetsa kwambiri chizoloŵezi cha mankhwala kukhala ndi fungo la formalin panthawi yosungirako pambuyo pokonza nsalu;
8. Palibe fungo la nsomba.

B) Ulusi Wopanga

Utoto ukhoza kupereka zotsatirazi za NYLON, DACRON kapena ulusi wina wa hydrophobic:

1. Kumva bwino kwa manja;
2. Kuuma koyenera komanso kukhazikika kwakukulu;
3. Kusamva madzi kwambiri komanso kutsukidwa kouma;
4. Palibe pamwamba utomoni chodabwitsa;
5. Palibe fungo pa nthawi yosungirako;
6. Kuchepetsa mavuto makina processing ndi kuipitsa.

Malangizo Ogwiritsa Ntchito

1. Zovala pansalu: Nsaluyo iyenera kukhala yoyera ndipo isakhale ndi chinthu chilichonse chomwe chingalepheretse kulowa kwa utomoni, kukonza bwino komanso kukhazikika kwamadzi, monga asidi, alkali, mchere kapena zinthu zina.
2. Kukonzekera Kusamba: Palibe njira zapadera zodzitetezera kapena njira zokonzekera kusamba, chifukwa mankhwalawa amatha kusungunuka m'madzi mumtundu uliwonse kutentha.Kusankhidwa kwa chothandizira kumadalira zipangizo zothandizira kutentha ndi njira yopangira;
3. Kugwirizana kwa Catalyst: Zothandizira monga YT-01, YT-02, YT-03 zitha kugwiritsidwa ntchito.
