Iyo yakadzika-tembiricha-inonyungudika mvura fiber inotorwa PVA seyakagadzirwa uye yakagashira gel kuruka nzira ine zvinotevera maficha:
1. Mvura yakaderera tembiricha inonyungudika.Iyo inosiya pasina chakasara kana ichinyungudika mumvura pa20-60 ℃.Iyo Sodium sulfide nzira inogona chete kuburitsa yakajairwa mafiber anonyungudika mukupisa kwe80 ° C kana kupfuura.
2. Inokodzera kugadzirwa kwemachira nekuda kwesimba rayo repamusoro refiber, raundi fiber muchinjiko chikamu, yakanaka dimensional kugadzikana, ine mwero linear density uye kureba.
3. Kudzivirira kwakanaka kune zvipembenene uye mildew, kumira zvakanaka kuchiedza, kuderera kwakanyanya kwesimba kudarika mamwe mafiibhi pakusangana kwenguva refu nechiedza chezuva.
4. Isiri-chepfu uye isingakuvadzi kuvanhu nenharaunda.Kusavapo kwe sodium sulfide kunotungamira kune yemahara guruva njodzi panguva yekutenderera maitiro.
